The Final Frontier

Nothing has inspired the human mind more than space. It has been the topic of countless books, films, tv shows, it even inspired a genre of music. And that’s just in the past 50 years, or so. Given the level science and technology are at right now, there’s very little we know about space. Still, some of the things we do know, are nothing short of fascinating, and here are some of them:

Fact: If you could somehow place Saturn into water, it would float. Of course, we would need a giant glass of water to test that one out first-hand, but that’s where science comes in. The density of Saturn is 0.687 g/cm3, while the density of water is 0.998 g/cm3. So there you go, it floats.



Fact: The moon is slowly moving away from Earth as we speak. This is caused by tidal effects. Each year, Moon steals some of the Earth’s rotational energy, causing it to slow down a bit, and then uses that energy to distance itself further away, around 3.8 centimeters. Scientists claim that when the Moon was formed, its distance from Earth was only 22,530 kilometers. Now the distance is closer to 450,000 kilometers.

Fact: The light we see on Earth right now is over 30,000 years old. Or, to be exact, the energy in the sunlight started out in Sun’s core 30,000 years ago, but took most of its time passing through dense atoms. Once it accomplishes that, it takes only 8 minutes to reach the surface of the Earth.

Fact: Although it makes for a serene and wonderful view, Sun is much more violent than it appears. Its core produces so much energy, every second, that it equates the strength of 100 billion nuclear bombs.

Fact: If you were to leave your footprint on the Moon, it may hang around there longer than you might expect. Seeing as there is no wind on the moon, your footprint has a good chance of staying there forever, barring the occasinal meteoric collision.

Fact: If two pieces of metal touch in space, they become permanently stuck together. This is true, although is sounds unbelievable. This wouldn’t happen on Earth, because metals would have a thin oxidized layer covering their surface. Theoretically, it might pose a problem for astronauts in space, as most of their tools are made out of metal, but those tools come from Earth, so they have an oxide layer around them as well. Unfortunately, the only evidence to support this claim comes from experiments done in a strictly controled enviroment, to provoke a certain reaction. The process is called cold welding.

After reading all this, it’s not hard to understand why space has captivated our curiosity for centuries, and why it still continues to push us forward in terms of technology and science, causing us to lift the bar every so often. Still, it is easy to see we haven’t even scratched the surface of that endless frontier that we call space.
