With all of the exploring that human beings are doing, I would wonder what would happen if we found such a scenario. There are surely many planets that are "suitable." It's just a matter of finding one that offers the "exchange" that humans can tolerate.

ies, hawks circling their prey, insects going towards light sources, hurricanes... could it be because of the path that the earth takes though space??

This is just a thought excercise. There is not right or wrong answer. Best story gets best answer.

I was wonder if the United States had a secret space program that was more advanced than NASA.

How Apollo’s speed was controlled for its safe landing of on lunar surface. As there is no atmosphere and hence can’t be landed like a chopper.
Again its take off speed is very low and should be decreases because of moon’s gravity until another rocket fired in opposite direction for thrust. And I notice from the video there was nothing left at bottom of Apollo for the next thrust. So why Apollo did not decelerate by the moon’s gravity after certain height.
And how did Apollo was accelerated after take off as acceleration is the rate of change of velocity which can only be possible in empty space by firing rocket from time to time.
A thrust of 3500 lbs was used for LM take off on lunar surface . How did the design engineers calculate the final design speed on the basis of 3500 lbs thrust and moon’s gravity at rendezvoused with CSM in lunar orbit. Or what was its final design speed at the rendezvoused with CSM in lunar orbit.

what is the % difference in terms of their masses between the actual force of attraction between two sperical masses the size and mass of the sun Ms
and the force of attraction as approximated by GMM/d^2
when the two planets' surfaces are less than 1 inch apart.

if your answer contains the double integral of:

[density(r1)].[density(r2)].[dV1].[dV2] /(r1-r2)^2

explain how this can be integrated.

I was wondering because the basis of this movie makes a lot of sense (the part about the USSR kicking America's butt in the Space Race and then they suddenly land on the moon), but as a theorist myself, I like to investigate before I believe.

I've read a bunch of posts from noobie astronomers wondering what type of telescope to buy and noticed many people recommend getting a goodset of binocuars first. How much detail can you actually see with a set of binoculars (bodies other than the Moon, say Mars or a nebula)? Do they make binoculars that mount to a tripod or do you just stay as steady as you can? What types and power are recommended for star gazing? Thanks much!

I understand the big bang theory.

My question is where did the stuff that blew up in the big bang theory come from

I do. I think as large as the universe is there is no way we are the only life form. As far as aliens visiting earth and kidnapping people for experiments,I think that might be a little far fetched. But I do believe they exist and have visited earth.
