Neglecting energy absorbed or reflected by Earth's atmosphere, the solar energy hitting 1 square meter of Earth's surface is 1360 J/s (the solar constant). How long does it take a baseball diamond (90 ft on a side) to receive 1 megaton of solar energy? (Hint: A 1 megaton bomb produces about 4 x10^15 J.)
__________years

There are comets, the sun light dying out, black holes? what is the risk of these coming? how long will it take? Would it scare everybody?
I would be scared I get worried about it because who knows when this could happen I would hope it wouldn't happen while i'm alive.

Apparently there are limitations to our global growth and it has to reach a certain time or level in the future. There must be scientific or economic models to better determine when that will be.

Which move faster?
comets or human built space probes?
I would guess comets.
Why don't we send out a probe. Land it on a comet. Have it take readings. Fly way out of our solar system.
Then when it comes back, we can get all of the data.

According to my logic (which is probably incorrect), since the moon is always in orbit around the earth, it should come between the earth and the sun at least every month or so. Please tell me why this is not so.

Hello,

Astronomors and scientists often refer to the Big Bang theory when they attempt to explain the creation of the universe. Generally, all matter was in "one tiny place," and then the matter was blown outward in an incredible explosion to create the universe.

My question is this: Describe the matter before the Big Bang occurred. In other words, of what substances did that matter consist? How did all of that matter end-up in "one tiny place" before the Big Bang occurred?

Thank you.

Sincerely,
D
