But still its just a theory and no supporting evidence.

if it has no supporting evidence... that would be a hypothesis. you're 28? and you don't even know what a theory is?

Hi there
I was just thinking , if the Einstein twins and slower time would be just a Doppler effect and nothing else ?
If the observer on earth, could see the clock in the rocket , going half of the speed of light , clock would bee seen as going at half speed.
Same with the twin ageing slower.
The thing not mentioned is that, if the rocket reverse with the same speed , clock will go faster ? Similar to ambulance going towards you, and the way pitch changes ?
It's again "things are not the way you see them" they are what they are
And if the speed of light is not the limit ( why would it ? ) , I wonder what the equivalent of sonic boom would be ? What if that is the explanation for ufo's appearing ad disappearing ?
And about time travel.
If you know the paradox of going back in time and shooting younger yourself in the head , for me it's enough proof for time travel being impossible.
I'm ready for getting flamed
cheers
