Astronomy & Space - November 2007

If the water had really covered the entire Earth up to the level of the top of Mount Everest, how much water would be required to do that, how much would it weigh, and what would the effect of the increased gravitational pull by the Sun be - would it have pulled the Earth out of its orbit and crashing into the sun?

There was a catastrophic flood - there is geologic evidence for this (it was over 600 feet deep, but that's not "the entire world" now, is it?). I know that there is not enough water on the Earth for this to have been possible, but its interesting as an intellectual exercise. Thanks in advance to all the smart people that can help me with this one.

if i know a planet's sidereal period and i know how far that planet is from the sun, assuming a circular orbit, how do i find out its synodic period?

i have uranus' radius of orbit = 19.23 AU
and its sidereal period = 84.33 earth years
how do i get its synodic period?
is there some simple formula?

cheers.

I asked this question last night. but all though I agree with has been written, I dont actual mean physical heating!

As within a microwave oven, microwave radiation causes molicules to vibrate and heat up. Gobal warming has seamingly increased in the last 30 years, around the same time we have been sending more satilates into space for mobile communications, radio dishes and mobile phone masts, and Wi fi. Pigeons flying in the path of radio dishes can be instantly cooked, so with all these's signals and radio waves, there must have an effect, in heating up the atmosphere.

I mean that If radio waves can cause molicules to vibrate and heat up.

Mobile phone masts have been opposed on health questions

A micro wave oven doesn't produce that much heat to cook. With so much radio wave and other radiation criss crossing the globe, then is'nt there a chance then, we are microwaving ourselves

My price range is $400-500 i want to be able to see the rings on saturn and the red spot on juipiter and the ice caps on mars but i don't think a 500 telescope can see all that. But if im wrong tell me.

Okay, so I have to write a two page argumentative essay over a controversial topic.

My topic was the Big Bang, and how I'm for the theory (being a physics major and all).

Well, my teacher decides to flip everybody's sides to where they're against the topic they're for, and vice versa.

So, I need help.

I know of a couple of theories of how the universe came to be. The one I'm most familiar with is the Static Universe theory by Einstein; but there's a problem. His theory was proven wrong.

So I need some other theories that are very possible.

Serious answers, please. Best one = 10 points.

Thanks!

Assuming mankind will not destroy man sometime in the future, to a fatal degree, do you think man will ever discover external life someplace in the universe?

Wouldn't it be interesting to see what time era they are in, and what their lifestyles are like, etc? Assuming they live in an organized, civilized society of course.
