14 Facts That’ll Make You Feel Simultaneously Scared And Amazed At Space

TIME IS NOT LINEAR. MY BRAIN IS BROKEN.

1. The universe is completely silent.

Sound on Earth travels through vibrations in the air. But in outer space, there is no air for sound to travel.

2. Astronaut footprints on the moon can last for a million years.

Since the moon has no atmosphere, there is no breeze to slowly erase footprints. They exist in a vacuum.

3. Over one million Earths can fit inside the sun.

If the sun were like an empty ball, you could fit 1.3 million Earths inside.

4. You can fit all the planets between the Earth and the moon, distance-wise.

This is only the case when the moon is at apogee – aka the farthest point from Earth. You can see a great breakdown here.

5. There are so many stars in the known universe, we can’t even count them.

@neiltyson I don’t know who to ask; are there more stars in the sky than grains of sand on Earth? A debate with wifey.

They are about the same: Stars in the observable universe & grains of sand on all the world’s beaches.

It has been estimated that there could be 1000 billion billion stars in the observable universe, based on a couple of assumptions about galaxy size and distribution.

6. Which makes you think about WTF is happening in the whole universe.
The reason why we can't see the whole universe is because some parts are too far away from Earth. Their light hasn't had enough time since the Big Bang to reach us.

7. Jupiter is so fucking huge. Earth isn’t even as big as the Great Red Spot.
Jupiter's Great Red Spot is about twice the size of Earth. The storm has been raging for over a century. WE ARE SOOOOO SMOL.

8. And Jupiter’s gravity is so strong that it actually protects us from a lot of collisions.
The planet has been dubbed the "vacuum cleaner of the solar system", because its gravitational force eats up asteroids or comets that are nearby, stopping them from colliding with Earth.

9. If you go to outer space (without a spacesuit), you could swell up to twice your normal size.
Due to low pressure, the boiling point of your bodily fluids decreases below your body's normal temperature, which is about 37 degrees celsius. This means your fluids will start to form gas bubbles and you will swell up – but you won't explode, because human skin is super stretchy.

10. Although you will probably fall unconscious after 15 seconds.
This is because your body would have used up all the oxygen by this point. Oh, and if you tried to hold your breath, your lungs would rupture.

11. If you fell into a black hole, you would get stretched out like spaghetti.
This is scientifically known as "spaghettification", and happens when "the gravity wants to sort of stretch you in one direction and squeeze you in another," according to Joe Polchinski, a physicist at the University of California, Santa Barbara.

12. And from someone else’s perspective, you wouldn’t disappear – your body would appear to freeze-frame and then you’d slowly turn red.
You however, would continue past the event horizon to your inevitable death.

13. When you look at stars in the sky, you’re actually looking back in time.
Light takes so long to reach Earth that by the time we see the light from the stars, years have passed. The exact time depends on how far away the star is.

14. And finally, time does not flow the same everywhere.
The faster you move, the slower time goes goes for you. This concept is known as time dilation and it only really makes a difference if you're travelling close to the speed of light. (As seen in Interstellar.)
