The Apollo moon landings were faked.
The answers to those questions are simpler than you may think. There are for the same reason you don't see stars during the day on Earth: The bright glow of daylight on the surface washes them out. U.S. sewn in them to appear as though they were moving. Without these wires, the flag would have hung straight down, making for a pretty lackluster photo prop. And the lunar modules, though heavier, didn't put prominent marks in the surface in some places because their mass was more evenly distributed than the astronauts' weight was in their boots.
NASA is a lie.
In reality, NASA was formed in 1958 "to provide for research into problems of flight within and outside the Earth's atmosphere, and for other purposes," according to the National Aeronautics and Space Act of 1958, which then-president Dwight D. Eisenhower signed into law shortly after the start of the space race against the Soviet Union. Since then, NASA has launched hundreds of satellites into orbit around Earth, the moon and several other worlds. In fact, NASA spacecraft have orbited, flown by or landed on every planet in the solar system. NASA also sends astronauts into orbit, where they conduct (ISS).
Not convinced? Try watching a rocket launch for yourself, or see the space station and other satellites with your own eyes with the help of a satellite tracker.
The Earth is flat.
One way of demonstrating to yourself that the Earth is round is to consider how orbits of satellites work. Satellites constantly "fall" around the Earth as they are pulled around by our planet's gravity; they just need to be traveling fast enough at a high enough altitude to not slam into the atmosphere. Or, you can look at the at the ISS.
Still not sold? . "The Earth looks flat because you aren't far enough away at your size," Tyson explains. "Your size isn't large enough relative to Earth to notice any curvature at all."
Planet Nine will kill us.
Although the planet's existence has not been confirmed, astronomers are actively looking for it to explain motions of some objects in the icy Kuiper Belt, a vast region of icy objects beyond Neptune. If the planet is actually found, the California Institute of Technology's Mike Brown (who is one of the original backers of the Planet Nine theory) says the planet .
While Area 51's true focus is classified, the U.S. government has acknowledged its existence (although the CIA officially calls it "Homey Airport" or "Groom Lake"). A part of Edwards Air Force Base, the area was a known location for high-technology airplane flights in the 1960s and 1970s. It first served as a proving ground for as early as 1955. UFO sightings reported in the area were indeed unidentified objects, but only because the planes were top-secret — not because they were flown by aliens.
There is a killer planet known as "Nibiru."
Years later, self-proclaimed psychic Nancy Lieder claimed to have communicated with extraterrestrials who said Nibiru would collide with Earth in 2003. When that didn't happen, the date was moved to 2012 (and linked, of course, with the ). Of course, the collision never occurred, the world didn't end in 2012 and no astronomer has ever found a planet on a collision course with Earth.
There is a face on Mars.
NASA followed up with taken from the Mars Reconnaissance Orbiter and the Mars Global Surveyor in 1998 and 2001, respectively. These new images made it quite clear that the "face on Mars" is nothing more than a trick of light and shadows on a completely normal Martian mound.
The moon Iapetus is an alien Death Star.
A Daily Mail article published in May 2016 . As "evidence," the article cited a photo taken by NASA's Cassini spacecraft in 2004. In the photo, there's a line around the moon's equator that resembles the equatorial trench around the Death Star. But this line isn’t nearly as interesting as the Death Star's trench, which houses the battle station's engines, thrusters and docking bays. That line is nothing more than a mountain ridge, and Iapetus is actually just made up of boring old rock and ice. Cassini has flown by the moon to take pictures several times without being blasted by deadly alien lasers.
Immediately after the Voyager returned its first images of Saturn's strange feature, even stranger theories arose to explain it, including that it was somehow related to alien technology, or perhaps even was a gateway to hell. The hexagon is not artificial, but rather a weird-looking hurricane at Saturn's pole. NASA has done several flybys of this region with the Cassini spacecraft, studying the haze particles and other features of the storm, to try to learn more about its weird properties.
Mars is as big as the moon.
Although Mars is indeed relatively close to Earth in a cosmic sense, it will never be as large as the full moon. It will appear as a red dot in the sky, just as the ancient astronomers saw it. If you'd like to see Mars magnified, take out a telescope or look at one of NASA's .
The moon will turn green.
The moon never actually turned green, although it can appear red during a lunar eclipse, when the moon passes through Earth's shadow. In the same way sunsets often appear red, sunlight is scattered as it passes through Earth's atmosphere, casting a reddish shadow on the moon's surface.
Skywatching columnist Joe Rao . He pointed out that a full moon actually took place on April 22, 2016, and speculated that the April 20 date of the "green moon" might have to do with "National Weed Day," popularly known as 4/20. Considering that the last green moon supposedly happened 420 years ago as well, this doesn't appear to be a coincidence.
As we all know, Earth did not actually experience that much darkness that year. (The article claimed that the alleged darkness was partly due to a Jupiter-Venus conjunction, which actually took place more than 500 million miles apart.) Darkness occurs when the Earth rotates, causing the sun to "set" on the local horizon. Brief periods of darkness can also happen when the sun is totally obscured during , which occur rarely in any particular spot on Earth. But even during an eclipse, Earth is never completely in the dark.
Zero-gravity day will make you weightless.
But, of course, nobody floated off the surface of Earth that day. Earth's gravity is too strong for people to become weightless. The only way to experience weightlessness without going to space is to ride aboard a plane that performs parabolas, with some including a few seconds of weightlessness. This is sometimes nicknamed the .
Alien spacecraft caused a mysterious explosion.
The Tunguska incident flattened hundreds of square miles of forest, and signs of the destruction were visible even decades afterward. At the time, news reports claimed that evidence of aliens was found at the site, but this claim was never substantiated. "The Russian team stupidly stated long before they went to Siberia that the main intention of their expedition was to find the remnants of an alien spaceship," Benny Peiser, a researcher at Liverpool John Moores University in the U.K., . "And bingo! A week later, that's what they claim to have found."
UFO was caught "refueling" at the sun.
However, NASA pointed out that the ," which has cooler and denser plasma than the outer atmosphere of the sun, or the corona. Scientists are still trying to figure out how solar prominences develop, but they're pretty sure it has nothing to do with aliens.
You can imagine that, with all of the rocks available on Mars, some of them would happen to look like familiar objects. In fact, the human brain tends to perceive meaningful images in random patterns - a phenomenon known as .
When evaluating the claims, consider that the Martian environment is extremely harsh to life as we know it; the surface is baked with radiation, the "air" is mostly carbon dioxide and there's not much atmospheric pressure.
I just saw a bright UFO!
While every situation is different, one common explanation for "UFOs" is actually another extraterrestrial object: Venus. Venus can be extremely bright when it's at its closest, because it's relatively near Earth. The planet is also extremely reflective because the sun's light bounces off the clouds. So before calling to say you've spotted a UFO, check your sky charts!
NASA can travel faster than light.
In reality, NASA is downplaying the reports. The engine in question is a prototype that is producing some interesting results, such as appearing to create thrust when there was no reason for this to happen – and thereby violating . That said, NASA has not yet verified the results from these tests, and the engine has not been widely discussed in peer-reviewed research.
We have launched balloons into space!
With the advent of high-resolution, miniature cameras, several people have decided to strap these cameras on to high-altitude balloons and take pictures from up high. They've caught glimpses of blackness and, at times, taken interesting tiny passengers along (such as these ). So they must be in space, right?
There are canals on Mars.
There are no artificial canals on Mars. Several spacecraft have flown by the planet or orbited it, and not one has caught signs of aliens from orbit. What they have seen, however, are smaller channels that were created by nature – likely from water, ice or other processes that cause erosion.
A star is flinging comets at Earth.
However, 2011 study , because the comet strikes in recorded history haven't happened with any regularity. The pattern that was recorded in the hoax is actually a statistical artifact, or the result of researchers trying to find patterns in nature where they do not exist, the study's authors found.
There's life on Venus.
These alleged life-forms on Venus are just an example of "letting your mind see patterns in low-resolution data that simply aren't real," Jonathon Hill, a research technician who processes images taken during NASA's Mars missions, . According to NASA, the objects that appeared to be moving were actually camera-lens covers that automatically popped off of the cameras after landing LiveScience reports. These half-circle objects were seen in images from and Venera-14, two identical spacecraft that landed about 590 miles (950 km) apart. Both had two identical cameras (one in the front and one in the back) so it makes sense that the covers would appear in different places. Another photograph that Ksanfomaliti said was a scorpion is actually a blur in the image.
An asteroid is about to crash into Earth.
NASA and a network of monitoring telescopes across the world are cataloging all known asteroids wider than 459 feet (140 meters) across in line with a . (Smaller asteroids, if found, are also cataloged.) Of the space rocks discovered so far, NASA has not found a single asteroid that has a high probability of hitting Earth in the foreseeable future. .
Aliens landed in Roswell, New Mexico
While rumors of aliens circulated, some people speculated that the crash was just a plain old weather balloon that might not have been recognized by the local community. The U.S. military has the "spacecraft" was actually a weather balloon sent aloft as part of Project Mogul, which involved flying microphones on high-altitude balloons to listen for sound waves generated by possible Soviet Union nuclear tests.
Climate change is not real.
While there are many components of climate change, the fact that . Temperature graphs show that the climate has not warmed this much, this quickly in all of Earth's history (as seen in geological records), and that the increase correlates with increased industrialization.
