I have confused. We should create law of addition of non-smultaneities. We can image any velocity(and bigger than c) as non-simultaneity. Then we can check any law of addition of velocities.

The Einstein's law is incorrect because we cannot use the same module of reverse velocities in two frames. 😝

Yes, i mistaken.

A very simple refutation of Einstein's law of addition of velocities.

When you have got change of momentum dp then any observer,in any frame, defines the your change of momentum as the same dp.

When they have equal masses.

When travelers ,relative to each other , have d momentum then it is the same in any frame.

Let's use conservation of momentums for correct addition of velocities V3×gamma3=v1×gamma1+v2×gamma2

Do you think that undefined opinios of mathematicians are more useful in physics than laws of physics? For y=x/x When we approach x to 0 there is no changing of the result.

You don't know what is 0/0. Then what do you try to explain?

Well. any2×0=0

Well. 0/0=unknown Then E1=unknown2×0=0 E2=unknown2×0=0

Teachets teached us 0/0=1 What is in Israel?

Do you want to dispruve the law? Or do you remake it?

Where?

I don't understand you. 0/0=1 Ask mathexperts.

Then p1 and p2=0. E=0 0/0=1 E1=12×0=0 E2=12×0=0 E is kinetic energy E1 and E2 are kinetic energies.

In S .

It is exactly incorrect because it violates energy momentum law. S' is traveling with velocity v1 in S. We acselerate body to S' then the body has momentum p1 and energy E1. Then we acselerate the body to v2. Then the body has momentum p and energy E . In the same time the body has momentum p2 and energy E2 in S'. The enegy momentum law is E1=(p1/p)2E E2=(p2/p)2E

Thanks.

My idea is so. Velocity v is between S and S' . gamma=1/(1-v2/c2)1/2. Object travels with velocity u in rame S. Norm of relation between distances and times is defined by gamma. u is rate of change of distance at time in S and it is the same when S travels in S'. We should only transform it relative to distance and time of S'. Then u transforms into u/gamma. And we should add velocity v. u'=v-u/gamma Einstein's velocity u' is another and therefore it changes norm of contracted and not contracted distances and times. Therefore it is incorrect.

I made correct math. Genady don't understand it because he is ortodoxal. You don't understand it because you understant no math at all.

Concrete mathematics was created by smoked brain. We cannot apply it anywhere.

We consider physics and the mathematics has no relation to the physics.

What experiment did Einstein present to the formula?
