Imagine 2 space ships flying away from you in opposite directions.
Lets say the are both traveling at speed 10 Mph.
You would observe both ships at the same speed (10Mph).
But if you are on one of the ships things are different for you.
Now 2nd space ship moves at speed of 20Mph due to you.
What if we change 10 Mph to 2500Mph? Than 2nd space ship moves at speed of 5000Mph due to you.
But what happens at very high speed and by really high I mean 150 000 miles/s ~0,8C .
Using same process we did previously we have answer 1.6c but that is not possible based on what Einstein figured out(speed of light is only absolute in our universe) so what now ?!
I spent a lot of time trying to figure what happens but I am still clueless.
Can ANYONE help me and my readers find truth?
You actually need to make the calculation in the framework of special relativity. For such high speeds, you cannot consider time as absolute.
And Einstein is not wrong, in contrast to what said the other comment. There is no proof he is (otherwise please show it to me). Note that having an alternative explanation is a totally different story that saying the explanation commonly considered is wrong. I also do not know about this alternative explanation and cannot therefore judge its relevance.

Thank you for answer. So you are saying by applying special relativity it is explainable ? You are probably right I just need to spend some time thinking about it.

That's indeed what I was meaning. The speeds are not simply added anymore. It is a bit more complicated, but nothing too complicated as well.

So the point where it gets more complicated is where? 0,5 C ?

At a much lower speed. When relativistic effects are negligible.

ohh but at low speed the effect is too small for us to even consider it ?

Responding here because of the nesting limit. If you want easy calculations, then you need to be non-relativistic. As soon as you go quick, relativity is at work and that's the price to pay. You can also achieve relativistic calculations at low speed and you will find that the results agree with the non-relativistic case.

The correct answer is that Einstein was wrong and Tesla was correct, that gravity is the fastest direct propagation speed in the universe. But there is also a speed of interference propagation that is almost instant across the universe.
But, you probably want to understand the physics as it is taught today in physics books. This is where relativity comes into play.
The two space ships, each travelling at 0.8c away from the planet. But, to each other, they are travelling about 0.96c away from each other. What is happening is that space is getting contracted along the axis of the two ships.
Not only does time get slower, but also space shrinks.

Thank you very much for answer! It acctually makes sense now !
