34. Saturn Phelps.

Saturn would float if you put it in water. Technically, this is true since Saturn, which is composed mostly of gas, is much less dense than water. However, finding a pool of water big enough may be a challenge… And, of course, the planet itself may not be the best swimmer. Most physicists agree that Saturn would fall apart pretty quickly if ever plopped it into this yet-to-be-discovered colossal pool.

33. Kaboom!

If you placed a pinhead-sized piece of the Sun’s core on the Earth, you would die from standing within 145 km (90 miles) from it. Why? Basically, it contains a wack ton of energy, and it’ll blow up like a freaking nuclear bomb.

32. Is there anybody out here?

Space is not a complete vacuum. There are about 3 atoms per cubic meter of space. Massive understatement of the century: that’s not a lot.

To put it in perspective, at sea level, there are approximately 2.5 x 10^25 air molecules in a cubic meter of air. That’s 250,000,000,000,000,000,000,000,000 atoms.

31. Avada kedavra!

Only 5% of the universe is made up of normal matter. 25% is composed of dark matter. 70% is dark energy.

30. Do you even lift, bro?

Neutron stars are so dense that a teaspoon of them would be equal to the weight of Earth’s entire population. In fact, Scientists agree that even Chuck Norris couldn’t bench press a neutron star.

Chuck Norris. Our writers believe this was shortly after he was told that he couldn’t bench press a neutron star.

29. Thanks, NASA.

You can’t actually see a black hole. This is because a black hole is indeed “black.” No light can escape from it, so our mere mortal eyes don’t pick up any light bouncing off it. In fact, it’s impossible for us to sense the hole through any of our instruments, no matter what kind of electromagnetic radiation we use (light, X-rays, whatever). The key is to look at the hole’s effects on the nearby environment, NASA points out.
