The speed of light is constant, or so textbooks say. But some scientists are exploring the possibility that this cosmic speed limit changes, a consequence of the nature of the vacuum of space.
The definition of the speed of light has some broader implications for fields such as cosmology and astronomy, which assume a stable velocity for light over time. For instance, the speed of light comes up when measuring the fine structure constant (alpha), which defines the strength of the electromagnetic force. And a varying light speed would change the strengths of molecular bonds and the density of nuclear

They’ve been able to slow light down in lab tests for a few years now.
it is so slow in ‘rats they can’t even see it
Hussein’s halo is going dark.
It slows down considerably when it hits 0bama’s skull.
Thanks for the article now I get to go read on Mach’s Principle and compare it with this.

ill probably get yelled at again for this but according to afrophysics obama isnt really black he is just so dense light bends around him
Shocker (not). I’m also figuring it’s a matter of time (possibly soon, considering this post) before they figure out that light isn’t actually the speed limit, light has “mass”, and that dark matter/energy doesn’t exist because it isn’t needed to satisfy their observations.
Addressing the universe mathematically will teach you an awful lot, but it doesn’t solve everything. I believe it’s a “forest for the trees” problem.
Of course, to a mathematician I’m an unqualified boob - but it’s not the first time I’ve sat back and said “well duh” at one of these “discoveries”.
Refraction, like in a prism, is due to light slowing down in speed as it enters the prism medium.
He’ll never see the light.
I distinctly remember being taught the speed of light varied with the density of the material it was going through.
Light is photons right?
If you can stop it then it seems to me that the speed of those photons changed.
I’ve been saying this for years, almost always to the great derision of the scientific types. If it was that important to me I could probably go back and find the FR threads.
Pinging my favorite cosmologists. In the past, we have had some discussions where I posited that the speed of light is not really a constant.
"Screw you guys. I'm not giving back my Nobel Prize.
GO NAVY!"
So slowly that you risk ramming it from behind.
Who is this fellow?

BOOKMARK.
Speed Limit: 186,000 miles per second
It’s not just a good idea, it’s the law.
