I found this on the BBC News Website:



If we are still only just detecting such massive objects that are relatively close to us, who knows what else could be out there?

vulcan?

Mirror Universe?

heheheheheh well i would laugh my head off if there was some pointy eared aliens liveing up there lol

Actually, we do need Gravity.

Gravity keeps our muscles strong and stops our bones from breaking down. By constantly having to push against Gravity, our bones and muscles develop and maintain their strength.

Astronauts have to constantly excercise whilst they are in space to ensure that their bones and muscles don't waste away. Even then, when they come back to Earth, they are unable to walk properly, because their legs have to get used to Gravity again. They wouldn't have this problem if we had Gravity generators, Of course.

I'm not a mathematician, physicist, or whatever, so I don't really know the laws that govern Gravity, but to my knowledge, Gravity is all about mass.

Everything in the Universe - including us - have a Gravitational pull on objects close by, it's just that you need to be the size of an Asteroid, Moon, Planet or Star for the effects to be noticable. The bigger the object is though, the greater its force of Gravity will be.

Life on Earth evolved to how it is now because of the climate, because of the pull of Gravity, because of mass extinctions, and because of a great many more things.

If the Asteroid hadn't hit the Earth 65 million years ago, the Dinosaurs would likely have still have been around - and mammals wouldn't now rule the Earth.

It would be the same on other Planets - the smallest random event could trigger a complete change in the evolution of life - or its failure.

I personally think that the chances of finding life that is similar to us is extremely remote, although I certainly don't doubt its existance - in one form or another.

Sorry if i've missed the point here, but what is a GravGen (GravityGenerator?), what does it do and what do you do with one?

first, humanities biggest problem is the assumption that everything is how WE see it, and 'know' it to be.

second, any geological question i can answer, becuase i am in my last year of geology at university.

thirdly, remember, the universe is held together by rules. if we understand the rules, we can find ways to manipulate them. just because a smart man floggs out a theory which is mathimatically sound, doesnt mean its the only solution to the problem. breaking the speed of light is only a matter of time. but even then we might not actually travel faster than the speed of light, but bypass it, and it would only appear to go faster. also remember this, if something has happened before, it is possible, and will therefore happen again in an infinate universe. there is, will be, or was life out there.

thats my rant
