Relativistic energy and mass |
The energy of a mass m is given by Einstein's equation of the Enery,
E=mc^2, where "c" is the speed of light.
However, what would happen when we put that mass m, for example, into
water?
The speed of light in water is different of the speed of light in
vacuum, so, provided that energy "E" is constant, will the mass m
increase? or "c" is always the speed of light in vaccum?
Thank you.

You got it. It is the speed of light in vacuum. Or, more exactly,
the speed of light in vacuum is c.

Lightspeed is a physical constant. The world viewed through your
profound ignorance must be of great amusement to you. Hey git - what
is the measured acceleration of Earth's gravity inside a fully
submerged, neutrally boyant submarine? Inside a submarine ascending
or descending at constant velocity?

Hey git! How come it takes longer to send a signal to Cassini than
it does to get the answer, fuckhead?

Hey fuckhead!

"we establish by definition that the ``time'' required by light to travel
from A to B equals the ``time'' it requires to travel from B to A. "
I'll repeat my question, imbecilic arsehole.
How come it takes longer to send a signal to Cassini than
it does to get the answer, fuckhead?
Your idiocy is based on a dumb definition, fuckhead.

No, and here is the misconception.
c is rather the universal limiting speed.
It happens that light travels at the limiting speed in a vacuum, but
that is irrelevant for the formula above.
However, what would happen when we put that mass m, for example, into
water?
Nothing, because that changes nothing about the universal limiting
speed.
The speed of light in water is different of the speed of light in
vacuum, so, provided that energy "E" is constant, will the mass m
increase? or "c" is always the speed of light in vaccum?
Thank you.

PD Light (photons) never change speed Going through water they travel a
greater distance. It takes photons 100.000 years to go from core to the
Sun's Surface. They use the proper theory here Absorbed and emitted

Sam Photons from the core probably take100,000 years to reach the sun's
surface Here you see the uncertainty principle coming into play

That's it.
Also off topic here. You want sci.physics.relativity.
