i am always skeptical to believe in space theories as most of them are just hypothesis and no one ever saw anything in person (or) sent some robots to take take pics beyond pluto :dream:

Though we can't see it in person we can see the photons reflected from those objects

There are no proofs in science bro but only convincing demonstrations. They may change with time. 

A hypothesis becomes science only when it is backed up by a repeatable experiment which proves the hypothesis.

 

The confusion seems to come from thinking similar to this : We all thought newton was right for 200 years but then came einstein who said sorry bro you were wrong. 

While the above  perception of science is prevalent, it is totally wrong. What newton said is still true today. You can run the same experiments independently and they will still succeed. However Newton's theory did not explain some observations. Under those conditions his model broke. Then came einstein with a model which worked even in the conditions where Newton's model failed. So Einstein's model is more complete. 

 

If something is proved in science experimentally then it remains true forever ( of course you need to run the same experiment under the same conditions)

Nothing is true forever. When you consider something as true forever, you will stop researching that.
