ok, I can buy that first answer, I guess I'm looking for a more drastic change though, almost stopping light

ok, maybe not stopping...........

actually, Yes... most defintely..

is has been done in an experiment.. where you pass a beam of light via different mediums, and were able to actually freeze the beam to a stop.. you can probably find the article on the times archive.. or perhaps Physics Today ..... quite impressive if you ask me..

however, light itself is a constant.. so, can you actually slow the actual speed of light?.. no. but the beam itself can be stopped....

The speed of light is affected by different mediums. Light travels slower through any material - water, glass, air.

In space however, there is not matter to form a medium to slow down or block the light. Therefor, light tracels constanty at the max speed for anything - 3*10^8 m/s

Light travels at different speeds in different mediums (such as, the speed of light in water is slower than the speed of light through air), if that is what you mean.

-------------edit----

As some people have noted, scientists have slowed down a photon of light to a standstill (see article below), but I suppose that the only way to actually change the maximum speed of light in a vacuum is to bend space-time itself by using extreme gravity from a black hole (which one guy below also said).

on the initiating we could comprehend that our theory of time will consistently be the comparable, a minute will consistently "sense" like a minute even although our velocity is on the edge of the fee of sunshine.we can't sense that we are residing longer if we pass swifter. what is going to alter, is how the observers are perceiving us. in the event that they could watch us travelling at very intense speeds, our strikes will decelerate added and larger the closer we get to the fee of sunshine. If we could pass decrease back and learn our clocks, there will be a substantial distinction in them. The time slows down for the observer that has been under acceleration forces, no longer the only that has stay in an inertial reference. Time additionally slows down under gravitational fields. we could comprehend that gravitational forces are the comparable as acceleration forces. All this that sounds so unusual, is defined in an common way in lots of books approximately relativity.

Stopping light is easy! If you want to accelerate light that can also be done! I read a scientific paper a few months ago about how some particle physicists supposedly acclerated light past the speed of light using electric fields.

you can make it appear that light is moving faster then the speed of light. However you are measuring the wave packet and the group velocity, which is not the same as saying its speed exceeded the speed of light.

No not in the same frame of reference. the speed of light "c' is constant. You certainly cannot stop it unless it goes into a black hole. Light has electromagentic prpoerties.

light can't be stopped. The speed is constant; it does not change at all. However, you can bend it.

yes! You can stop light itself. Since light moves very fast, one thing that could stop it is gravity. Like blackhole. It has massive gravity which prevents light to escape.
