Heh, I assume I'm supposed to be 'Mr Science'? Yeah, guess I can get like that! I like science, I won't deny it, and I think some actual - y'know - facts would be quite handy in this thread...
...and now I will prove that reputation XD

You only think a Blackhole will kill us because Hollywood glamourised the truth. Not even they know what goes on inside a black hole. They just glamourised what they thought was the truth to turn it into a Horror Movie.
Lastly, this could be our only chance to find out what happened at the beginning of the Universe. If the Higgs Boson doesn't exsist, then hundres of years of work could go down the drain and we'd have to re-learn everything about how life was created here on Earth, how the Earth came into being. Because at this minute, no-one is completely sure about how the Earth was created. How is it so round? Why does it have a different Atmosphere to other Planets?
How does the gravitational pull of the Sun keep us from endlessly falling into nothingness? |
Well... A black hole would almost certainly kill us because its gravity would be SO strong that the tidal forces would rip our bodies (and everything else) in to its elementary particles before we got too close. But true, we don't actually know what's inside it - that's something we'll probably never know, unfortunately, due to its very nature. I mean, we couldn't well send a probe in to have a look if it's going to get atomised!
And we do know many of those. It was (and these are the best available scientific theories, which I should also point out are different to the word 'theory' in that the latter is basically a guess and the former has facts to back it up) thought that Earth was formed from the accretion disc around the sun as it was forming, with matter congealing and gathering together under the influence of gravity. It's round because of gravity as well - everything is being pulled towards the centre, so anything too tall or too out of shape will get crushed down by its own weight.
The atmosphere... Well, that's something we're still working on, but we're looking at Venus and Mars (extremely similar terrestrial planets which have an atmosphere, even if it's pretty tenuous on Mars, but there's plenty of evidence that it used to be thicker) to get answers for that.
And we know how Earth stays in its orbit, thanks to Kepler's laws of planetary motion and ESPECIALLY Newton's law of universal gravitation (although you use Einstein's laws of general relativity for more specific examples), but how gravity itself works is still a bit of a mystery - it's thought to be its own particle, the graviton, but we still need to learn more about its nature, and why it's so weak compared to the other three fundamental forces, and if it, y'know, exists. That's actually one of the things that the LHC is investigating, bringing us back on topic!
Aaaand I'm going to be quiet because I'm REALLY living up to my Mr Science reputation ^_^
