Something to wonder and ask about universe?

We Answered:

How universe started?
There is the theory of Big Bang. Which explain "theoretically" the beginning of the Universe.

Is there an end to universe,is there a line of end?
Well, Theories say that the Universe has no end. The Universe its expanding, and its velocity is increasing. There are theories that talk about dark energy, which says that it could be the cause why the Universe is expanding and instead of slowing down for gravity, its speeding up.

And how the hell did people discover all those planets(not the ones in solar system) i mean the ones 150.000 light years away from earth.
Planet the size of Earth is near impossible to see in other solar systems, most of the planets that were discovered are at least the size of Jupiter, and they were discovered because they affect the motion of the start and also, if we are lucky, we will be able to see it while its orbiting the star in the side facing us.

"What kind of technology people use to reach that far in space,I've watched a show on National geographic about planets out of solar system 100 light years away from earth"
The Hubble telescope I believe is one(if not the best) telescope in the planet for now, and with it, scientists have been able to discover thousands of things.

There is 500 other solar systems...Is there 500 other signs of life?
Not only 500 other solar systems, there are more than that, and signs of life, it all depends, there could be life anywhere, but microscopic life, but im assuming you mean Intelligent life, and so far we have not found any planet able to support life.

Isn't the best/cheapest and most efficient way to sequestrate carbon just leaving coal in the ground?

We Answered:

Yes, definitely. Greedy consumers are the cause of the waste through their excessive demand. The one good thing about the recession is that their awareness of waste is growing, and the demand is declining. Sure it's for the wrong reasons, but it's still in a good direction. If the cost of gas goes up, the recession will get much worse, and waste will go down even more. I would much rather see change for good positive reasons, but that's not in my control.
