does outer space exist

There are conspiracy theories about national tragedies, about high-profile crimes, even about celebrity couples. These effects can be minimized through a regimen of exercise. [71][72][73][74] The International Telecommunication Union responsible for radio communication (including satellites) defines the beginning of deep space at about 5 times that distance (2×106 km). Because the idea that the moon landing was faked is just the beginning. They also create aurorae seen at high latitudes in an oval surrounding the geomagnetic poles. This experiment resulted in the first mercury barometer and created a scientific sensation in Europe. [144] This was greatly exceeded in 1942 when the third launch of the German A-4 rocket climbed to an altitude of about 80 km (50 mi). The framework for international space law was established by the Outer Space Treaty, which entered into force on 10 October 1967. Lord Kelvin in 1871 suggested that life came to earth on meteors. This pressure is high enough to prevent ebullism, but evaporation of nitrogen dissolved in the blood could still cause decompression sickness and gas embolisms if not managed. Classified by conspiracy theorists as a "rogue planet," people believe that Planet X/Nibiru is going to spell humanity's destruction. The Kármán line, an altitude of 100 km (62 mi) above sea level,[7][8] is conventionally used as the start of outer space in space treaties and for aerospace records keeping. 4. Numerous experts, researchers, reporters, and alien believers have shared their thoughts and theories, and many of these theories support the notion that we are not alone in the universe and that there is life in outer space. [109][110], Since 1958, outer space has been the subject of multiple United Nations resolutions. Longer-term exposure to weightlessness results in muscle atrophy and deterioration of the skeleton, or spaceflight osteopenia. Despite the fact that the scientific consensus is that climate change is both real and manmade, you have probably heard all sorts of explanations for global warming. There is also gas, plasma and dust,[79] small meteors, and several dozen types of organic molecules discovered to date by microwave spectroscopy. [42], As a consequence of rapid decompression, oxygen dissolved in the blood empties into the lungs to try to equalize the partial pressure gradient. [121] In 1648, his brother-in-law, Florin Périer, repeated the experiment on the Puy de Dôme mountain in central France and found that the column was shorter by three inches. I don't disagree with any of the answers, but symantically, I would have to say, “NO”. He concluded that there must be a vacuum between the Earth and the Moon. This volume nearly coincides with a region of space known as the Local Bubble, which is characterized by a lack of dense, cold clouds. For the general concept, see, "Interstellar space" redirects here. At or above the Armstrong line, fluids in the throat and lungs boil away. Panspermia is the common name given to the concept that life originated in outer space and then migrated or was transported to earth. [122], In 1650, German scientist Otto von Guericke constructed the first vacuum pump: a device that would further refute the principle of horror vacui. And yet the conspiracy exists. More specifically, exposed bodily liquids such as saliva, tears, and liquids in the lungs boil away. [77] The heliopause in turn deflects away low-energy galactic cosmic rays, with this modulation effect peaking during solar maximum. [43] Rapid decompression can rupture eardrums and sinuses, bruising and blood seep can occur in soft tissues, and shock can cause an increase in oxygen consumption that leads to hypoxia. Atmospheres have no clearly delineated upper boundary: the density of atmospheric gas gradually decreases with distance from the object until it becomes indistinguishable from outer space. [65], Although it meets the definition of outer space, the atmospheric density within the first few hundred kilometers above the Kármán line is still sufficient to produce significant drag on satellites. The U.S. is a signatory to the 1967 Outer Space Treaty, which prohibits placing nuclear weapons in space. Health. [10] This leaves open the question as to whether the Universe is finite or infinite. [137] The modern measurement of the cosmic microwave background is about 2.7K. This status as a common heritage of mankind has been used, though not without opposition, to enforce the right to access and shared use of outer space for all nations equally, particularly non-spacefaring nations. Since that time, uncrewed spacecraft have successfully examined each of the Solar System's planets, as well their moons and many minor planets and comets. As a sound wave passes through the air, the air pressure in any given spot will oscillate up and down; picture the way water gets deeper and shallower as waves … [87], The local interstellar medium is a region of space within 100 parsecs (pc) of the Sun, which is of interest both for its proximity and for its interaction with the Solar System. [90], Intergalactic space is the physical space between galaxies. Due to the high cost of getting into space, human spaceflight has been limited to low Earth orbit and the Moon. I really dont see how thats possible. Experiments suggest we create time. [120], The Italian scientist Galileo Galilei knew that air had mass and so was subject to gravity. [111] Four additional space law treaties have been negotiated and drafted by the UN's Committee on the Peaceful Uses of Outer Space. [116], In 350 BCE, Greek philosopher Aristotle suggested that nature abhors a vacuum, a principle that became known as the horror vacui. [10] Matter that remained following the initial expansion has since undergone gravitational collapse to create stars, galaxies and other astronomical objects, leaving behind a deep vacuum that forms what is now called outer space. And while some of that is scientific theorizing, some of it involves space-related conspiracy theories that will definitely have you scratching your head. In other words, there’s an incredible drop in both temperature and pressure when it comes to the depths of outer space as compared to what we have here on Earth. [37] Seeds of Arabidopsis thaliana and Nicotiana tabacum germinated after being exposed to space for 1.5 years. This can cause nausea and vomiting, vertigo, headaches, lethargy, and overall malaise. [140] The shorter term space is older, first used to mean the region beyond Earth's sky in John Milton's Paradise Lost in 1667. Initially, more than 50% of astronauts experience space motion sickness. I don't think there's really anything else that needs to be said here. Astronauts might float in space, but that doesn’t mean gravity doesn’t exist up there. "Lucifer" is supposed to both refer to the fact that the devil's name also means "morning star" and to be an acronym for "Large Binocular Telescope Near-infrared Utility with Camera and Integral Field Unit for Extragalactic Research" — which is a mouthful. [97], A spacecraft enters orbit when its centripetal acceleration due to gravity is less than or equal to the centrifugal acceleration due to the horizontal component of its velocity. [33] Cosmic rays can damage electronic components and pose a health threat to space travelers. If you thought it was ridiculous that some people think President Obama wasn't born in the United States, just wait until you hear about the people who think the CIA teleported him to Mars in the 1980s. In 2014, the European Space Agency landed a probe on comet 67P, but some people believe it wasn't a comet at all, but an alien spacecraft. (There is quite likely a correspondingly large number of neutrinos called the cosmic neutrino background. Geospace extends from Earth's atmosphere to the outer reaches of Earth's magnetic field, whereupon it gives way to the solar wind of interplanetary space. All … The latter is also called Nibiru by believers, and stories about it go back to 1995, when a woman in Wisconsin began publicly saying she received messages from the aliens who inhabit the planet via an implanted device. Latest. It all depends on who you ask. [141][142], For most of human history, space was explored by observations made from the Earth's surface—initially with the unaided eye and then with the telescope. [13], Estimates put the average energy density of the present day Universe at the equivalent of 5.9 protons per cubic meter, including dark energy, dark matter, and baryonic matter (ordinary matter composed of atoms). The inner boundary is the ionosphere. [118] As late as the 17th century, the French philosopher René Descartes argued that the entirety of space must be filled. The energy required to reach Earth orbital velocity at an altitude of 600 km (370 mi) is about 36 MJ/kg, which is six times the energy needed merely to climb to the corresponding altitude. Magneto-hydrodynamic processes in active elliptical galaxies produce their characteristic jets and radio lobes. [136] This theory holds that the universe originated from a very dense form that has since undergone continuous expansion. Those displaced molecules bump into their neighbors, and then those displaced molecules bump into their neighbors. [34] According to astronauts, like Don Pettit, space has a burned/metallic odor that clings to their suits and equipment, similar to the scent of an arc welding torch. For example, the temperature in the Boomerang Nebula is 1 K,[29] while the solar corona reaches temperatures over 1.2–2.6 million K.[30], Magnetic fields have been detected in the space around just about every class of celestial object. [131] But the scale of the Universe remained unknown until the first successful measurement of the distance to a nearby star in 1838 by the German astronomer Friedrich Bessel. [41], Out in space, sudden exposure of an unprotected human to very low pressure, such as during a rapid decompression, can cause pulmonary barotrauma—a rupture of the lungs, due to the large pressure differential between inside and outside the chest. For decades it was assumed that the Sun had a bow shock. This decrease in pressure was further demonstrated by carrying a half-full balloon up a mountain and watching it gradually expand, then contract upon descent. In physics, aether theories (also known as ether theories) propose the existence of a medium, a space-filling substance or field, thought to be necessary as a transmission medium for the propagation of electromagnetic or gravitational forces. [49] Most space suits use around 30–39 kPa of pure oxygen, about the same as on the Earth's surface. [11] As light has a finite velocity, this theory also constrains the size of the directly observable universe. But what they see out in the void is a little different than what the rest of us observe. [145] This was followed by the first human spaceflight in 1961, when Yuri Gagarin was sent into orbit on Vostok 1. These storms increase fluxes of energetic electrons that can permanently damage satellite electronics, interfering with shortwave radio communication and GPS location and timing. The Local Bubble contains dozens of warm interstellar clouds with temperatures of up to 7,000 K and radii of 0.5–5 pc. There is no such thing as the “outer space” that we have been conditioned to believe in by charlatans who claim to be scientists. [80] A cloud of interplanetary dust is visible at night as a faint band called the zodiacal light. It was replaced by Albert Einstein's theory of special relativity, which holds that the speed of light in a vacuum is a fixed constant, independent of the observer's motion or frame of reference. It forms a cavity in the Orion Arm of the Milky Way galaxy, with dense molecular clouds lying along the borders, such as those in the constellations of Ophiuchus and Taurus. It has effectively no friction, allowing stars, planets, and moons to move freely along their ideal orbits, following the initial formation stage. They film the effect using zero G planes and huge swimming pools as shown in the videos. People who believe the Earth is flat have a whole host of strange opinions on how things like the sun and moon are really situated, but at least some believe they are equidistant from Earth. Where does outer space start? With their "Declaration of the First Meeting of Equatorial Countries", or "the Bogotá Declaration", they claimed control of the segment of the geosynchronous orbital path corresponding to each country. By Stefanie Waldek. The surviving books of the Hsüan Yeh school said that the heavens were boundless, "empty and void of substance". [106][107], The Outer Space Treaty provides the basic framework for international space law. [42] Even if the subject's airway is fully open, the flow of air through the windpipe may be too slow to prevent the rupture. It is a void that sits there waiting to be filled, as in “I saved space for dessert” or “I found a great parking space.” If you follow this notion, then space is something that can exist by itself without any matter to fill it. But most of space doesn't have any stars. Learn more. Svante Arrhenius coined the term in 1908 and is considered the father of panspermia. Can't you accept that outer space exists for variety of reasons and whether you are there to observe it and ask questions about it is totally irrelevant to outer space. In the high energy range, the flux of electrons is only about 1% of that of protons. [20] In spite of this, extinction, which is the absorption and scattering of photons by dust and gas, is an important factor in galactic and intergalactic astronomy. [138] The expression outer space was used as an astronomical term by Alexander von Humboldt in 1845. Non-thermal radio sources have been detected even among the most distant, high-z sources, indicating the presence of magnetic fields. [40], Even at relatively low altitudes in the Earth's atmosphere, conditions are hostile to the human body. For the album, see, sfn error: no target: CITEREFUnited_States (, International Union of Pure and Applied Chemistry, International Telecommunication Union responsible for radio communication, Committee on the Peaceful Uses of Outer Space, Timeline of knowledge about the interstellar and intergalactic medium, "Existence and nature of dark matter in the universe", Annual Review of Astronomy and Astrophysics, "Where does space begin? [133] The distance to the Andromeda Galaxy was determined in 1923 by American astronomer Edwin Hubble by measuring the brightness of cepheid variables in that galaxy, a new technique discovered by Henrietta Leavitt. In fact, some even say that it is far more sophisticated than our civilization. "The occupants in outer darkness are there for various lengths of time. [51] Other effects include fluid redistribution, slowing of the cardiovascular system, decreased production of red blood cells, balance disorders, and a weakening of the immune system. [48] Supplemental oxygen is needed at 8 km (5 mi) to provide enough oxygen for breathing and to prevent water loss, while above 20 km (12 mi) pressure suits are essential to prevent ebullism. [82], Interstellar space is the physical space within a galaxy beyond the influence each star has upon the encompassed plasma. [76] Interplanetary space extends out to the heliopause where the influence of the galactic environment starts to dominate over the magnetic field and particle flux from the Sun. [22] The Earth's atmospheric pressure drops to about 0.032 Pa at 100 kilometres (62 miles) of altitude,[23] compared to 100,000 Pa for the International Union of Pure and Applied Chemistry (IUPAC) definition of standard pressure. In 1640, he demonstrated that an established force resisted the formation of a vacuum. Others believe the Earth is a disc covered by a dome instead of a planet orbiting through outer space. Before reliable rocket technology, the closest that humans had come to reaching outer space was through balloon flights. [147], The first spacecraft to reach escape velocity was the Soviet Luna 1, which performed a fly-by of the Moon in 1959. [88], When stars are moving at sufficiently high peculiar velocities, their astrospheres can generate bow shocks as they collide with the interstellar medium. [159], Interstellar travel for a human crew remains at present only a theoretical possibility. The region outside Earth's atmosphere and extending out to just beyond the Moon's orbit, including the Lagrange points, is sometimes referred to as cislunar space.[68]. ... Scientists have yet to show any conclusive proof that dark matter does in fact exist. Once the deoxygenated blood arrives at the brain, humans lose consciousness after a few seconds and die of hypoxia within minutes. [25][26] All of the observable universe is filled with photons that were created during the Big Bang, which is known as the cosmic microwave background radiation (CMB).

Do Aliens exist? By comparison, the air humans breathe contains about 10 molecules per cubic meter. Star formation in spiral galaxies can generate small-scale dynamos, creating turbulent magnetic field strengths of around 5–10 μG. Perhaps the swathes of space strung with gossamer nebulae serve some aesthetic purpose, beauty wrought on an inhuman scale. [66] This region contains material left over from previous crewed and uncrewed launches that are a potential hazard to spacecraft. This, despite the fact that many experts say the footage was actually impossible to fake with 1969 technology, but perhaps the conspiracy theorists assume that government technology was secretly more advanced? [150] In August 2012, Voyager 1 became the first man-made object to leave the Solar System and enter interstellar space. According to some conspiracy theorists, Obama was part of a secret CIA program in the 1980s that sent "chrononauts," including a young Obama, to explore the solar system via teleportation. [35][36], Despite the harsh environment, several life forms have been found that can withstand extreme space conditions for extended periods. [15] Unlike matter and dark matter, dark energy seems not to be concentrated in galaxies: although dark energy may account for a majority of the mass-energy in the Universe, dark energy's influence is 5 orders of magnitude smaller than the influence of gravity from matter and dark matter within the Milky Way. The rate of orbital decay depends on the satellite's cross-sectional area and mass, as well as variations in the air density of the upper atmosphere. [123], Back in the 15th century, German theologian Nicolaus Cusanus speculated that the Universe lacked a center and a circumference. It does mean, however, that humankind has yet to leave the Earth’s atmosphere. [91], Surrounding and stretching between galaxies, there is a rarefied plasma[92] that is organized in a galactic filamentary structure. [32] The peak flux of cosmic rays occurs at energies of about 109 eV, with approximately 87% protons, 12% helium nuclei and 1% heavier nuclei. These plasmas form a medium from which storm-like disturbances powered by the solar wind can drive electrical currents into the Earth's upper atmosphere. This is evidenced by the spectacular pictures sent back by the Hubble Space Telescope, allowing light from more than 13 billion years ago—almost to the time of the Big Bang—to be observed. Perhaps the most bizarre space-related conspiracy theory is the one that seems to imply outer space doesn't exist at all — or at least is radically different than we believe. The density of the IGM is 5–200 times the average density of the Universe. NASA. Molecules in outer space exist because their atoms happened to bump into each other and stick. So, space probably does exist, but we're not advanced enough to understand how or why yet. The altitude where atmospheric pressure matches the vapor pressure of water at the temperature of the human body is called the Armstrong line, named after American physician Harry G. Armstrong. [58], Geospace is the region of outer space near Earth, including the upper atmosphere and magnetosphere. [38] A strain of bacillus subtilis has survived 559 days when exposed to low-Earth orbit or a simulated martian environment. [57] Interstellar space then continues to the edges of the galaxy, where it fades into the intergalactic void. Large Binocular Telescope Near-infrared Utility with Camera and Integral Field Unit for Extragalactic Research, wasn't a comet at all, but an alien spacecraft, Donald Trump has even claimed it's a hoax, other planets in the solar system are warming up, people who think the CIA teleported him to Mars, Classified by conspiracy theorists as a "rogue planet,", at least some believe they are equidistant from Earth, NASA and world governments are covering up. [100] Spacecraft with a perigee below about 2,000 km (1,200 mi) are subject to drag from the Earth's atmosphere,[101] which decreases the orbital altitude. Microgravity also has a negative effect on human physiology that causes both muscle atrophy and bone loss. [124] These ideas led to speculations as to the infinite dimension of space by the Italian philosopher Giordano Bruno in the 16th century. We've been taught that time and space exist. When an object moves — whether it’s a vibrating guitar string or an exploding firecracker — it pushes on the air molecules closest to it. [31], Outside a protective atmosphere and magnetic field, there are few obstacles to the passage through space of energetic subatomic particles known as cosmic rays. [83] The cataclysmic explosion of a supernova generates an expanding shock wave consisting of ejected materials that further enrich the medium. [84] The density of matter in the interstellar medium can vary considerably: the average is around 106 particles per m3,[85] but cold molecular clouds can hold 108–1012 per m3. In 1935, the U.S. Explorer II crewed balloon flight reached an altitude of 22 km (14 mi). The incredible picture that 'PROVES' there is life on other planets THIS astonishing image is the long-awaited proof that alien life DOES exist, scientists have sensationally claimed. [58] The contents of interstellar space are called the interstellar medium. [3][4] Observations suggest that the majority of the mass-energy in the observable universe is dark energy, a type of vacuum energy that is poorly understood. The distances to the nearest stars mean it would require new technological developments and the ability to safely sustain crews for journeys lasting several decades. Leviathan (yes, you, the smug one). [56] The Van Allen radiation belts lie within the geospace. (There is a small group of researchers who believe viruses may even have come here from outer space, an idea known as panspermia.) – Aerospace Engineering, Aviation News, Salary, Jobs and Museums", "Survival of Plant Seeds, Their UV Screens, and nptII DNA for 18 Months Outside the International Space Station", "How do we know when Voyager reaches interstellar space? [89][90] A bow shock is the third boundary of an astrosphere after the termination shock and the astropause (called the heliopause in the Solar System). The first successful planetary mission was the 1962 fly-by of Venus by Mariner 2. Believe it or not, there are people (like presumably whoever made the video above) who think that NASA is trying to turn Jupiter into a second sun within our solar system. [60], The day-side magnetopause is compressed by solar-wind pressure—the subsolar distance from the center of the Earth is typically 10 Earth radii. [114], In 1976, eight equatorial states (Ecuador, Colombia, Brazil, Congo, Zaire, Uganda, Kenya, and Indonesia) met in Bogotá, Colombia. In reality, what goes up, comes back down, there is no point high enough where everything just suddenly goes weightless. Outer space, often referred to simply as space, refers to the empty areas within the universe that are not occupied by the atmospheres of celestial bodies.Although the earliest use of the term "outer space" is attributed to Alexander von Humboldt in 1845, it was popularized by English science fiction writer H. G. Wells, who used the term in his 1901 book The First Men in the Moon. We know that stars and planets outside our solar system exist, and these, too, were created for the glory of God. It covers the legal use of outer space by nation states, and includes in its definition of outer space the Moon and other celestial bodies. Above this altitude, isotropic gas pressure rapidly becomes insignificant when compared to radiation pressure from the Sun and the dynamic pressure of the solar wind. The interplanetary zodiacal dust emits a diffuse near-infrared radiation that can mask the emission of faint sources such as extrasolar planets. These atoms are ejected into the interstellar medium by stellar winds or when evolved stars begin to shed their outer envelopes such as during the formation of a planetary nebula. Yes, some people believe that the Earth is heating up because the sun is heating up. These observations indicate that the spatial geometry of the observable universe is "flat", meaning that photons on parallel paths at one point remain parallel as they travel through space to the limit of the observable universe, except for local gravity. There are several standard boundary designations, namely: In 2009, scientists reported detailed measurements with a Supra-Thermal Ion Imager (an instrument that measures the direction and speed of ions), which allowed them to establish a boundary at 118 km (73.3 mi) above Earth. [94][95][96] When gas falls from the filamentary structures of the WHIM into the galaxy clusters at the intersections of the cosmic filaments, it can heat up even more, reaching temperatures of 108 K and above in the so-called intracluster medium (ICM). The incredible picture that 'PROVES' there is life on other planets THIS astonishing image is the long-awaited proof that alien life DOES exist, scientists have sensationally claimed. The radiation of outer space has a different temperature than the kinetic temperature of the gas, meaning that the gas and radiation are not in thermodynamic equilibrium. By Stefanie Waldek. The atoms account for only 4.6% of the total energy density, or a density of one proton per four cubic meters. Outer space is a vast expanse that we have so much more to learn about, which is why it's hard to flat-out deny the possibility that other intelligent lifeforms exist. The low density of matter in outer space means that electromagnetic radiationcan travel great distance… Why is NASA trying to turn Jupiter into a second sun? I mean, I'm not an astrophysicist, but I'd imagine that having our planet suddenly sandwiched between two suns and their strong gravitational fields would probably be pretty bad. This was followed by crewed rocket flights and, then, crewed Earth orbit, first achieved by Yuri Gagarin of the Soviet Union in 1961. The duration of space sickness varies, but it typically lasts for 1–3 days, after which the body adjusts to the new environment. [99], To achieve an orbit, a spacecraft must travel faster than a sub-orbital spaceflight. When this happened, matter and energy became decoupled, allowing photons to travel freely through the continually expanding space. And while we've all heard theories about the moon landing being faked, or the idea that the government covered up an alien spaceship crash in Roswell, New Mexico, there are some lesser known conspiracy theories that are even more perplexing. He showed that the star system 61 Cygni had a parallax of just 0.31 arcseconds (compared to the modern value of 0.287″). Much of this chemistry is driven by collisions. [94] It consists mostly of ionized hydrogen; i.e. He believed that the Universe, while not infinite, could not be held as finite as it lacked any bounds within which it could be contained. This video explains why.All footage and music from Space Engine. Seriously , WHY does everything HAVE to have purpose for it's existence. The Orion Nebula is located within the central bright region of this scene, where massive star formation is most intense. [149] The first fly-by of Mars was by Mariner 4 in 1964. [75], Interplanetary space is defined by the solar wind, a continuous stream of charged particles emanating from the Sun that creates a very tenuous atmosphere (the heliosphere) for billions of kilometers into space. When you say, "Planet X," you could be referring to one of two different things: the real planet researchers think they've discovered in our solar system, orbiting our sun at a great distance, or the planet conspiracy theorists think houses a hostile alien race and/or is going to destroy the Earth.
