How Can Galaxies Travel Faster Than Light?

Get Astronomy tweets here http://twitter.com/DeepAstronomy Probably my biggest regret when I made the Hubble Deep Field in 3D video is saying the phrase "these galaxies are racing away from us, in some cases faster than light". I had originally thought I was being clever and the comment would spur discussion. instead there was no discussion, only name calling and I mightily regretted putting it in there. Anyway, this video was a long time coming, I had been meaning to make this for some time to illustrate what I was talking about.

Fantastic channel, really loved it!
-
sad that we will never learn billions of those galaxies. everything is fading away while we still here on earth.

Universe .if you see stars . does that exists . mauby in our minds .
-
I fear with the Trumpies and idiocracy on the rise, that the science like this beautiful video is becoming rarer and rarer. I love the input from Deep Astronomy. Beautiful and well structured. A pleasure to watch.

did u ever hear the name Halton Arp?
-
Did you have permission to use this video and voice
-
I still think tired light makes more sense.
-
looking way back in the past
-
Sooo the universe itself can expand faster than the speed of light? Brain explosion
-
thay was awesome and educational

How Can Man Kind Travel Slower Than A Snail? Simple Their Still Using Primitive Technology AKA Chemical Rockets ROFLMAO
-
That is sad. :'(

The notion that space is expanding was invented to explain away Hubble's observation that galaxies are moving away faster than light, to support Einstein's hypothesis that nothing can move faster than light. But, light is unaffected by space.... Distance means nothing to light.... Motion causes redshift, not space...... Space is the only thing that "exists" by not existing at all. It is merely distance between phenomena. Space is nothing, the void. Space is not that which fills the void ie; energy or force. But, the lack there of.

I believe our visible universe is a quark within a larger entity.
-
faster than the speed of light because light has a point of origin, while the universe has no point of origin. think of pointing to a single number in infinity and saying where the point of origin of that number is. it is that it is.
-
Matter cannot travel faster than the speed of light. Any measurement that postulates it is in error. (Ask Einstein.)
-
Relativity says that as a mass approaches the velocity of light, that it's mass gets heavier and it's mass will approach Infinite Mass if it reaches the velocity of Light. Wouldn't Infinite Mass pretty much destroy the entire Universe?

The sonic boom of Chuck Norris' roundhouse kick is why galaxies are moving away from us at faster than the speed of light. If you seek death, ask him to demonstrate.

It's kind of like having a bee flying around in your car while you're driving; the bee doesn't know it's moving any faster than it's flying. If you're car is moving at 55 mph, so is the bee.

So space time expansion is creating a naturally occurring warp effect. So conversely the galaxy we observe as super luminal would observe our Galaxy traveling at super luminal velocity as well.
