Hubble : The Most Distant Galaxies (Music: Oxygene 1 by Jean Michel Jarre)

Shameless plug here.

For anyone interested in exploring the universe, you could try "Celestia". Its an excellent free program that allows you to travel in real time (or light speed) to any point in the mapped universe at any point in time, look at our own sun, speed up the birth of the solar system and even just look up from any point on Earth for a cloudless nights star-gazing.

I wont post a link just in case its against some policy or another, but its on Google etc...

Yes, I would highly recommend Celestia too, I have been using it for years.

If God created such an immense thing....why would he worry about human suffering or existence? :S... Read the Star Maker, it's probably the best sci-fi book ever written.

If a galaxy is 4 billion light years away when it emitted light, why would it take 12.7 billion years for the light to reach us? I thought the speed of light was the same for all observers. What am I missing? Is it time dilation?

[speedfreek67]

At these huge cosmological scales, it is the expansion of the universe which puts more distance between us and that light, as the light is travelling towards us.

The expansion can increase those huge distances faster than light can cross them. By the time that light reaches us, the region of space that galaxy was in is now nearly 28 billion light-years away.

I don't get it. I need to brush up on my astrophysics lol.

[IamDuhmb]

Wait so when we look at distant galaxies we see old stuff right?

[speedfreek67]

Yes, whenever you look out into space you are looking back in time. When you see the Sun you are seeing it as it was around 8 minutes ago! This is due to the finite speed of light.

The light from the most distant galaxies took around 13 billion years to reach us!

[MrZoolook]

Strictly speaking, whenever you look at anything, because of the time it takes light to reach you, whatever your looking at is in the past... on an infinitely small scale of course!

my want to understand the cosmos and the reson for our exsistance is killing me inside.

[TryItAgain123]

I have to say you couldn't have chosen any better song than this. There's just a mystic spacy kinda sence in it. Truly haunting...

[road66agent]

truly enjoyed your video thanx for posting

[mankman1]

awesome video. very interesting to see what looks to have been the big bang??

[redrobincleveland]

Question what does it mean to you that there are other galaxies out there?What if other planets got the whole evolution thing down packed eons ago.Would it also mean that traveling at light speed is extremely difficult to do?What if there are beings that have been in existence before the earth even cooled down?Should we feel threatened that an advanced civilization that doesnt fight over contries but over whole galaxies could one day come and wipe us out.Our best technology is primitive to them.

Makes me believe more and more in all migthy God... nice video and music, thanks for posting it.

[Kysos2]

So many beutiful places, in this universe. I wanna flyyyyyyyyyyy :DDD

[steelsfirm]

Awesome!
