Speed Light

(link CNN)

Captain Samantha Cristoforetti is flying in the space yet, studying the human

body reaction in that enviroment.

She didn't reply at my question concerning the light behavior under a big

propulsion, but it needs to wait the coming back on earth. That's the moment

in which the space ship records a propulsion which helps it to change the

orbital way.

In fact, tough the actual speed is around 28.000 Km/h, the motion

corresponds to a static state, being everything inside the ship at the same

velocity.

The equivalence principle says that each mass, launched in the space under

acceleration, records the same gravity force that would record on earth, so, if

Captain Cristoforetti will ever try to measure the possible light deflection in an

accelerated state, she'll try it during the back way. Meanwhile there's a new 

discovery which regards the light speed.

Everybody knows that light speed is an universal constant, its worth is the

same everywhere. A researchers staff from Glasgow University and HeriotWatt

University, discovered that speed light changes changing the space in

which it moves.

We have different and several space structure, so they tried to let a light ray

moving in a different space form, recording a different speed in confront the

absolute one, which is 299792 K/meter per second

(http://www.sciencemag.org/content/early/2015/01/21/science.aaa3035).

In that contest the speed light is minor of 0,001 per cent, so, as scientific

method requires, the trials must be repeated again and again, until the

international community approves the new result, avoiding possible scandals,

as the neutrinos one recorded a couple of years ago.

It remains to wait, something which will break the ordinary classic and

relativistic phisyc.
