Is the speed of light the fastest speed in the universe?
Timemaster56
If one thinks about the possible states of the Universe, there are three possible situations - it's expanding, it's standing still or it's contracting. Einstein made, what he described, as his biggest blunder by assuming it stood still - as he said, a few seconds thought should have shown that a stationary Universe will immediately start to collapse under gravity. Hubble observed that objects in the Universe are moving away from Earth and that more distant objects are moving faster. The explanation of this comes from General Relativity and is interpreted as an expanding Universe, however it takes a few minutes calculation to realise that as we think about the further reaches of space, it is expanding at rates far greater than the speed of light (c). This seems to contradict Special Relativity and is getting a bit beyond my knowledge(!), but its solved by not thinking of the edge of the Universe zooming along well beyond c, it's not zooming into anything, it's simply getting bigger. So, yes it is expanding, and at enourmous (by our standards) rates.

∙ 14y agoAs far as we know, yes. In addition,we must understand maximum speed can be made within a vaccum and so, as such, the speed of light and all forms of electromagnetic energy travels at "c".

What is the fastest speed with anything can move?
speed of light
What is the fastest speed of anything in universe?
The fasted "known" speed in the universe is the expansion of the universe itself, at about 74km/s per 3m lightyears. That is incredibly fast. The fastest obseved would be light at of course, lightspeed, or rougly 300,000,000m/s.
How long is 9 trillion kilometers away from earth?
That is approximately equivalent to 1 light-year. That is to say, if travelling at the speed of light - the highest possible speed in the Universe - it will take a year to get there.
Why light-years are used to measure distances in the universe?
because it is the fastest way to measure in very long distances for example earth to other far away planets
Which modem has the fastest speed and what is the speed?
Verizon DSL Wireless
What is the fastest speed of any object in the universe?
The speed of light. 300,000 km/h, is the fastest speed of any object in the universe.
Which is the fastest thing in Universe?
Tachyons are theorised to be the fastest particle in the universe their slowest speed being the speed of light. But until they are proven to exist, light is the fastest thing in the universe.
What is the fastest speed possible?
The Fastest speed possible in the Universe is the speed of light in a vacuum exceeding 299,792,458 meters per second.
What is the difference between speed and light?
Speed is how fast something moves. Light is a form of energy carried by massless photons, these photons move at the speed of light, which is the fastest speed that anything in the universe can travel.
What is the fastest speed that there is?
You yourself do not have a speed limit of any kind. Everything else in the universe has the maximum speed of: Your Speed + the Speed of Light. However it is impossible to determine your own speed because there is no stationary point of reference in the universe.
Why do you measure distance in the universe in light years?
It's the fastest speed anyone can prove exists. Any speeds in excess of light speed are still just theory. Some scientists believe it is the fastest speed that will ever be achievable.( a cosmic speed limit.)
Which was the fastest the speed of light or the speed of sound?
speed of light
Is light speed the fastis?
Light speed is the fastest known speed.
What is the fastest moveing object in the universe?
Light.
What’s the speed of light?
Light is a "universal speed limit" and, according to Einstein's theory of relativity, is the fastest speed in the universe: 300,000 kilometers per second (186,000 miles per second).
Where is the speed of light at its fastest?
The speed of light is fastest in a vacuum. All other media slow the speed of light down, albeit very slightly.
Can you go the speed of light?
no, it is impossible the fastest you can go is 99.9 the speed of light , even if u run on the ship nature will slow u down, if u over come it there is a 99.9% u will destroy the universe. The only thing that can go the speed of light is light.
