10 Space Facts That Will Both Terrify And Amaze You

1. The Speed Of Light.


Everybody loves to imagine themselves flying through the galaxy at the speed of light, That roughly 299,792,458 meters per second. However, the reality might be less fun and a lot more fatal when coming into contact with an object moving at light speed. Hydrogen atoms transform into intensely radioactive particles that could easily wipe out the crew of a starship and destroy electronics in seconds. Just a few stray wisps of hydrogen gas floating through the cosmos could have a radioactive output equivalent to a proton beam created by the Large Hadron Collider.

2. The Moon.


Every year our moon gets about 4 centimeters further away from the earth and while this might not seem like much. At first, it could have devastating effects on our planet in the future although the Earth’s gravitational field should be enough to keep the moon from spiraling into space for good. The increasing distance between it and Earth will eventually slow the rotation of our planet down to the point where a single day will take longer than a month and our ocean’s tides are locked in place.

3. Black Holes.


Typically formed out of the death of massive stars black holes are super dense regions of space. With so much gravitational pull that they trap light and warp time just a small black hole. In our solar system would throw planets out of orbit and tear our Sun to pieces if that wasn’t scary enough on its own. Black Holes can hurtle across the galaxy at several million miles per second leaving trails of destruction in their wake.

4. Gamma Rays.


The most powerful type of explosion in the universe gamma-ray bursts is intense high-frequency bursts of electromagnetic radiation. That carries as much energy in milliseconds as our Sun will give off in its entire lifespan. If one of these rays were to hit Earth it could strip the atmosphere of ozone in seconds and some scientists even attribute a mass extinction 440 million years ago to gamma-ray bursts hitting the earth.

5. Zero Gravity.


Scientifically referred to as microgravity this condition occurs when an object is in a state of freefall and appears weightless. Although it may look like fun to float around like astronauts prolonged time in zero gravity conditions can have long-term mental and physical effects on humans.

6. Cold Welding.


Here on earth gases in the atmosphere react with metals to create a thin layer of oxidization the vacuum of space, however, has no atmosphere and therefore causes no oxidation to form on metals leading to an interesting reaction this reaction is called cold welding and it occurs when two metals of the same molecular makeup are pressed together and fuse together permanently as if they were one piece while this may sound neat it caused quite a few problems on the first satellites and can make in space repairs very tricky.

7. Alien Life.


The universe is massive and unbelievably old so the chances of other planets similar to Earth evolving life is not unlikely at all. According to Fermi’s paradox, the high probability of extraterrestrial life out in space is contradictory to the lack of apparent evidence. Supporting it at this point we aren’t sure which is scarier the fact that we might not be alone in the universe or the possibility that we are.

8. Rogue Planets.


Launched into space after the formation of their planetary system rogue planets our planetary bodies. They’re free to roam the cosmos crash into things as they go because they do not orbit a Sun rogue planets often have freezing surface temperatures. However, due to their molten cores and icy insulation, some scientists theorize that these free-roaming planets could contain massive subterranean oceans that support life.

9. Travel Times.


In 1969 it took the Apollo 11 lunar module three days to land on our own natural satellite the moon. Since then our technology has increased rapidly we could expect to reach Mars in seven to nine months and reaching Pluto would only take about ten years. Distances outside of our solar system become even more extreme even traveling at the speed of light. It would take us over four years to reach the nearest star Alpha Centauri on and over 100 thousand years to reach the galactic center of the Milky Way.

10. Extreme Temperatures.


Depending on where you are in space chances are you’re going to find yourself in some pretty extreme conditions the heat put off by a supernova can reach temperatures of 50 million degrees Celsius or more. Five times that of a nuclear explosion on the opposite end of the spectrum the cosmic background temperature of space measures minus 270 degrees Celsius. Just slightly warmer than absolute zero you definitely won’t want to forget your jacket.
