The sun is basically a ball of fire, right?
But if it is, then how can it exist?
I mean, for fire you need oxygen but in space there is no oxygen, it's a vacuum.
Can someone tell me how the sun is possible please?

[This sounds like such a stupid question]

Beyond what is known as the physical universe, what is there? So to speak, what is it expanding into? I know we can only generate theories, but I would love to hear a great one. Thank you

All substantial evidence and logic surrounding the supposed US moon landing in 1969 seems a bit forced, even contrived. Does anyone with some astronomy / space exploration background care to anonymously shed some light on this subject?

Say an astrounaut throws a hammer out of a space craft. It will get some arbitrary orbit. Will this hammer remain in space or fall down through earths atmosphere? My take on this is, since earth has gravity it should get down. Also, how does the hammer get orbital propulsion to remain in orbit for whatever time it remains there?

I think airplains are eatting up the ozone.
I think airplains could release tanks of Ozone at high altitude.
Each flight could add even a small amount.
I understand Ozone expands out and up and very little is needed to stop harmful rays!
Or.. why not Rockets or balloons?

If not ... "Why not???

I know that the smaller object is pulled in by the gravity of the larger object but the smaller object must have some kind of counter-acting force on its own which propels it around in a circle instead of collapsing into the object. What keeps the object moving? Will the smaller object eventually crash into the greater object?

When you look into space, you are looking back in time. For instance, if you look at an object 100 light years away, you are seeing something as it was 100 years ago. This being the case, why can we not look back to the beginning of the universe?
