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.
What else can I help you with?
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
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 of any object in the universe?
The speed of light in a vacuum, which is approximately 299,792 kilometers per second, is considered to be the fastest speed at which any object can travel in the universe according to the theory of relativity.
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 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.
The velocity of light represents a cosmic speed?
The speed of light is basically the speed limit in the Universe.
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.
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
What is the fastest thing that can travel?
The answer to "What is the fastest thing that can travel?" is light. Light can travel faster than any other thing in the universe!
Which particle travels the fastest?
There are some particles that travel at the speed of light - mainly, the photon (the particle that makes up light), and the (hypothetical) graviton. No particles are known to travel faster than that, and it doesn't seem likely that this is at all possible.
Is blinking the fastest thing in the world?
Nope, Tachyons might just be the fastest thing in the world...look it up for full description.
Is light speed the fastis?
Light speed is the fastest known speed.
