There was no big bang. There was no start to time. The red shift we also is due to inter stellar antimatter interacting with light. You are a smart, use your brain.

@YDDES NASA is full of shit.

@kaderoder Hubble seing galaxies but not lunar landers has nothing to do with the distance. It depends on how many arc-seconds the object occupies in the sky. And, we could see a lot of galaxies with our naked eyes if the eyes were much more light-sensitive.

@Chev4206 Try doing some research genius.No telescope,even hubble,has the resolution to see the landing sites.If you`re interested then the LRO and JAXA moon probes have recently taken images of apollo landing sites.They`re on utube under "ultra close up apollo 11".

[Chev4206]

@kaderoder Yes. Why don't (they) point Hubble at the moon and show us the Apollo landing sites? Because it would show fuck-all. One day the truth will be known.

LOL at 0:20.. Finally they will penetrate the universe.......

@kaderoder If I could guess, its due to the minimum focal length of the lens in question. Think of it sorta like this: close one of your eyes. Take an object, doesn't matter what it is, hold it at arms length and then focus your open eye. Now slowly move it towards that open eye. You'll see more and more detail (depending on how good your eyesight is) until eventually it gets so close to your face, it becomes fuzzy. Once it gets fuzzy, you've gone closer than your eyes minimum focal length. >

[kaderoder]

Huh? We can see galaxies from 13 billion light years away, thanks, but its technically too difficult to point something at the Moon and give us a clear view? I can smell BS.

[popeyeus]

So if a light image looks the same wither it is coming at us or going away except for the dopler effect and frequency light shift ,  time in relation to distance is the only thing that is changing along with the frequency of the image. The speed of light is constant.
