I think change of momentum/energy per measurement unit is dangerous due to that the change isn't simultaneous to different parts of body.There factors can be defined .

Crimean GDP per capita grows with Russian help ,but it is temporary phenomenon.

People of development will brake development of Russia and its allies.Germany should be cautious,because it isn't scientific empire as was in beginning of twentieth century.

Turn an armchair then danger of positive acceleration = danger of negative acceleration Well. What about math?

Dangers to human body.

How to define a level of danger of acceleration in gravitational field and without gravitational field?

You are right, but professional American politicians are more correct, because they do not lose vigilance.

I think similar referenda like in Crimea are forbidden in Russia.

My calculation is correct!

t'=gamma(t - xv/c2) gamma = 1/(1-v2/c2)1/2 You can try to use the formula.

t = 100 years = 3155692544.5 seconds In your case: dp=dt*m*a v=p/(gamma*m) v=tma/(gamma*m) v=ta(c2-v2)1/2 / c v2c2=t2a2(c2-v2) v2=t2a2c2/(c2+t2a2) v = tac/(c2+t2a2)1/2 v = 298,448,718 m/s a - initial acceleration p - momentum created by invariable force

The speed will be more than "c". Every subsequent 1 m/c2 of acceleration takes more energy than previous,therefore such acceleration can continuously be during 10 years never.

Firstly you should develop your science up to a superiority.

The idea wasn't dangerous. Supporters of the idea were dangerous.

How?

I don't understand your theory without math.

Then what is created by you?

Only critical angles have symmetries relative to 90 degrees Because thetas critical +thetao critical = 180 degrees

http://en.wikipedia.org/wiki/Relativistic_aberration_formula Yes, but thetas critical=120 degrees thetao critical=60 degrees blue shift : theta<thetacritical red shift : theta>thetacritical

Seems I start to understand why that is important. When theta > pi/2 then positive speed turns into negative speed. For 0.8c thetas critical = arccos((1 - 0.6)/(-0.8))=arccos(-0.5)=120 degrees The observer sees blue shift when thetas < 120 degrees The observer sees red shift when thetas > 120 degrees For 0.8c thetao critical ~81.34 degrees

For 0.8c thetas critical = 60 degrees 90 degrees > 60 degrees 30 degrees < 60 degrees If thetas=90 degrees then light has blue shift, I am agreed. Does light have blue shift if thetas=30 degrees ? How does your formula work here?

beta=v/c thetas - thetao = arctan(v/c) What is thetacritical ?

I am afraid we misunderstood Janus. See relativistic explanation of light aberration: http://en.wikipedia.org/wiki/Aberration_of_light#Relativistic_Explanation tan(phi)=sin(theta)/gamma(v/c+cos(theta)) You can see deflection of perpendicular lines at different speeds and change of color shift from "red shift" to "blue shift". http://en.wikipedia.org/wiki/Relativistic_Doppler_effect Visualisation Diagram 2. Demonstration of aberration of light and relativistic Doppler effect.

Maybe I was wrong earlier. http://en.wikipedia.org/wiki/Relativistic_Doppler_effect fs / f0 =gamma(1+ v * cos theta /c) blue shift is when fs/f0 < 1 then: gamma(1+v*cos theta/c) < 1 v*cos theta < (1-gamma)c/gamma
