Space Light

(link CNN)

Some day ago, I sent a question to Samantha Cristoforetti, the equipe italian

member who's now aboard the International Space Station around the earth,

which asked if light, at 28.000 Km/h speed, deflected its beam, as the Einstein

elevator principle suggests. The question was born from different

interpretations which can be read in the several notes written from scientists

and physicians. Some of them says that light deflects its beam, faithfull to the

Equivalence Priciple, some other says that light follows the space time curve,

generated from the mass which rests on it. All of us know the Special

Relativity formula, which establishes that a beam light, closed in a moving

space ship, at high speed next to the light one, can be seen from a stationary

observer like a deflected beam, which suggests the time dilation at that speed.

It's called Relativivty just because the effect is only related respect at the

stationary observer. The case changes when the light could be curved from

the velocity, in absolute terms, because the time dilation becomes an universal

principle. Anyway, we all wait for the experiment aboard the ISS around the

earth, who knows, may be something new gets out, may be a new born Jesus.
