WE KNOW THE SPEED OF LIGHT IS 186,000 MILES PER SECOND... BUT WHAT iS THE SPEED OF DARK?

Answer 1

It's the same as the speed of light. If the Sun "went out", we would be aware of it 8.32 minutes later when the light stopped. Why? Because it takes light 8.32 minutes to arrive here from the Sun. Thus, the sunlight you see right now left the Sun 8.32 minutes ago.

Thus, the speed of dark is equal to the speed of light.

Answer 2

Hey, is this one of those trick questions? Actually there isn't a "speed of dark" per se. Visible light is part of what's called the spectrum which goes from infra-red to ultra-violet. The light we see is somewhere in the middle. Every wavelength in the spectrum moves at the speed of light.

However, scientist have recently learned that over 90% of the universe is "missing". While studying how the stars and galaxies behaved with each other gravitationally, they realized there wasn't enough mass to account for how they interacted with each other.

Enter "Cold Dark Matter" (CDM) - not to be confused with black holes. Unlike other matter in the universe, CDM doesn't react with other matter electromagnetically - no light, no radiation, nothing. But it is there. The idea of CDM has bee around since Einstein published his paper on relativity. It has been detected through a phenomenon called gravitational lensing. If you look through a lens, you'll notice how the objects you're looking at are warped, especially around the edges. CDM acts as a huge lens and the objects we see behind it are distorted (to see an image of this type the keywords "Hubble+gravitational lensing"). This phenomenon has been observed everywhere in the universe. It may be impressive but scientists would like to have more direct proof. Any matter that behaves like this is worth studying.

I don't know if this even remotely answers your question but there it is.

Answer 3

Okay, this is really beginning to get on my nerves now. This stupid question has been asked countless times. Listen, asking this question won't make you smart, it just makes you stupid, because first of all darkness is the absence of light, it doesn't travel, that means whenever light leaves a place, darkness fills it up. Therefore it is obvious that if somehow darkness traveled it would travel AT THE SAME SPEED OF LIGHT. I mean come on, have you ever seen darkness fill up a place before light left, or darkness gradually filing up a place? No, you idiot!

Answer 4

Light is comprised of massless particles called photons....if your question is refering to invisible particles, then the speed would depend on whether or not the particles have mass. Only particles WITHOUT MASS can travel light-speed....particles WITH MASS can only travel sub-light speed.
NOTHING goes faster than light-speed...the fact that it's even called "light-speed" is a bit of a misnomer...ANY particle, whether it's technically "light" or not, that has NO MASS travels 186,000 miles a second.

Answer 5

You could look at the speed of dark in two ways:

1 - What follows behind a photon is dark so you could postulate that the speed of dark is the same as the speed of light.

or

2 - The speed of dark is zero simply because dark is the absence of light.

Since I don't believe that dark travels... I would agree with the 2nd theory.

Answer 6

I dont know if this is a serious question but it made me laugh when i read it. Im gonna have to agree w/ some of these answers and say the speed of dark is ZERO!

Answer 7

Actually, the speed of light is 186,202 miles per second.

Answer 8

Dark does not have a speed. It is stationary and exists everywhere all the time. You can't see it when light is present.

Answer 9

Since dark is opposite to light the speed of dark is -186,000mps.got that.

Answer 10

Faster than the speed of stupidity.
