Visit my website at http://www.junglejoel.com - in this episode of Hubblecast, Dr. J explains how the Hubble Space Telescope can "look back in time" to see the Universe as it was billions of years ago. Not only can we see vast distances with this telescope, we can look back in time as well. Please rate and comment, thanks!

Sorry, but not once in this video did they say the Earth was 8 billion years old or even imply that via some form of math like 13-5=x, can you guess x boys and girls? Care to explain again where you got that idea or just admit you pulled that number out of your ass? Now had you said that there were 8 billion years of this Universe's past where the Earth had not even formed yet, then I might cut you some slack. But you didn't, you said "the earth is only 8 billion years old" and you are wrong.

It truly would be just big ol' waste of space if we were the only ones here... Quite a thought-provoking video, nice job guys.

Okay, now that the video is over I'll devote a little more time to your comment. The Earth is not 8 billion years old, where did you hear that? The Earth is more like 4.54 billion years old. The Sun is about 4.6 billion years old. So there is only about a 60 million year difference between their ages. The Universe itself is about 13.8 billion years old. The Milky Way is nearly that old. Given those figures I don't see where you get 8 billion unless you just felt like throwing a number out there.

no.

a photon of light doesn't know what the speed of light is.
