I heard a theory i dont know if its true or not just wanted to get an explanation from someone smart enough to figure it out
the theory said that if you measure a distance of lets just say 10ft then divide that in half you get 5ft and then continue dividing in half you can go forever 5=2 1/2=1 1/4 and so on
there is no shortage of numbers which they said means in essence there should be an infinte amount of space but if theres an infinite amount of space then how come i can measure out 10ft and walk from here to there its a pretty well known theory cant remember who came up with it.
could someone smart please explaine this in a way other than saying something like because its wrong or saying and i thought i was stupid

If given a chance will you go to the Moon ? I will not because I am scared that something may go wrong and I will not see my family again.

A loaf of bread weighs 3.3 N on Earth.
What should it weigh, in newtons, on the moon, where the acceleration due to gravity is one-sixth that on Earth? What should it weigh on Jupiter, where g is 2.64 times Earth's gravity in Newtons?

cause there seems to be phyiscal proof. like the roswell crash, they recovered pieces of the ship. And implants that doctors have taken out of people that are made up of material not on earth.

I asked b4 but didn't give any examples

Therefore allow me to give some examples

1.) there's no wind on the moon why was the flag waving, was it b/c the astronaut was shaking it, if so that was a pretty hard shake.

2.) The lighting, there couldn't have been that much light on the moon at the time, the sun can't reach all parts and light every single part.

3.) How come when the shuttle thingy landed it didn't make a blast crater? How come moon dust didn't fly everywhere?

4.) How come in most of the pictures claim to have been taken on the moon in different places. Like in one for example it has the same background as another but yet it says it's 2 miles apart yeah right!

5.) How come we don't see any stars?

I believe that the whole thing was shot at Area 51, in the desert, I mean the desert surface kinda resembles the moons so called surface.

I'm no scientist or anything, just a guy who likes looking at the moon, the stars, and whatever else crosses the eyepiece of my telescope. I was just wondering if there were any online communites or clubs I could join just to chat with other Amateur Astronomers, casual star gazers or if it's possible real Astronomers! Just curious, thank you!

If so, how? I can understand being able to artificially create Earth-like atmospheric conditions including pressure, oxygen content, temperature, etc. However, what about gravity, the lack of which causes a loss of bone density in astronauts? Would exercise alone prevent the bone density loss?
