I have read that the velocity of light has been decreasing since the beginning of the universe. If I start travelling at .999 times the present velocity of light and after certain time, the velocity of light decreases beyond this value, would we be travelling faster than light then?

Nice try, but no. The speed of light in a vacuum represents a cosmic speed limit that relates mass to energy--it's not just an arbitrary number. The mass of an object increases the closer it gets to the speed of light, regardless of what that speed is. At the speed of light the mass of anything with mass is infinite--which is impossible--which is why it's a cosmic speed limit. If you get moving at .999 the speed of light, and then light slows down, you will have to increase your energy input to go .9995 the speed of light, and so on. Unfortunately, your mass is increasing exponentially at this point, and there's not enough energy in the universe to make you go faster. If you have mass--you stuck at less than the speed of light.

P.S. I was going to avoid the issue of whether or not light has "slowed" but since that has now been raised,,,,it's a load of crap. Or, more to the point, it's not a valid scientific theory that can be proved or disproved by experiment. I was trying to answer your question within your assumption instead of arguing about it.

No.
The velocity of light is not just slowing down. The velocity of light is the speed limit of anything with mass, and is the only absolute measure in the universe. Everything in the universe is slowing down at the same rate as light, so if you were traveling at .999 times the speed of light, you would always stay at .999 times the speed of light.

I have never heard of the speed of light "slowing down".
The speed of light is a limitation on mass because we can never hope to accelerate any amount of mass to that velocity since the energy required would be infinite as the mass gets heavier and heavier.
However, there are tricks that can be employed to effectively get around this cosmic speed limit. If you could create an apparatus that could warp space-time to your liking and also manage to keep your ship and device suspended inside a "bubble" of our space-time that is thinly connected to the rest of the universe, you could do it. Like folding a piece of paper, instead of drawing a line from point A to point B you could simply connect points A and B by bringing them together to virtually occupy the same space. This would be time travel as well.
You could also look for a wormhole.

If you were to start off at .999 * the velocity of lighty starting off then you would already be traveling .999 times faster than the speed of light. Now if you were to start from 0 to .999 and gradually through the next thousand of years doubling your velocity of .999 then within a matter of a couple thousand of years you would have reached the speed of light and within a couple of thousand of years afterwards you may then have reached the point of traveling faster than the speed of light. But take my advice if you want to travel faster than the speed of light go 88mph with a flux compastitor in a dolorian that always worked for me lol.

No.
That and light is not slowing down. Holy **** that is a ******* creationist myth and was discarded YEARS AGO as complete nonsense.
The experiments were faked by creationists. Light has been empirically measured since the 60's as completely and udderly consistant. Even before then with inaccurate measurements it was still consistant.

in case you look at a wave hitting a coastline at an attitude you will see that the connecting disturbance between the shore and the wave travels speedier than the wave. the same is actual with gentle hitting a curved merchandise. The disturbance between the floor of a curved planet and the gentle from an merchandise which contain a action picture star will holiday speedier than the gentle itself. additionally there's a caveat approximately speedier than gentle. How we comprehend the maths tells us that no longer something can holiday slower and thoughts-set the cost of sunshine however the maths will postpone in case you do no longer thoughts-set the cost of sunshine yet already are above the cost of sunshine. regrettably we exist under the cost of sunshine so we in basic terms can no longer get right of entry to something speedier than the cost of sunshine so for us it would not exist because of the fact we will not work together with it.

mayb there are faster wave then wave light speed
actually accorrding to relativity theory
time start to get slow and slow, the path get small and smaller
then u could travel faster than light
if u @ speed of 0.84c if i remeber corretly u do what light do in sec
cuz the relativity theory

its not that traveling the speed of light is impossible, but accelerating to the speed of light is impossible.

I don't know where dinizle got that number, but it's wrong.
The speed of light is actually
1799884800000 furlongs/fortnight.
