A new world record has been set for the most distant astronomical object ever observed, astronomers have viewed light from a star that exploded 13 billion years ago, just 640 million years after the Big Bang occured.
A star that exploded 13 billion years ago has set a new record for the most distant astronomical object yet observed. Light from the blast, known as a gamma-ray burst, has been travelling across the universe since just 630 million years after the Big Bang that launched the cosmos.

obviously the Earth isn't the center of the galaxy. My question is, why do we point to fixed point in time, (in only one direction) & base the age of space off of that?...It would serve better, IMO, to find 2....at the same time, 180 degrees from the previous point. I'm positive the 13 billion year old exploding star would have an equal in the opposite direction...So why not estimate the universe @ 26 billion years old? Seems almost like common sense. I don't understand what you are saying. Yes, if something exploded 13 billion years ago its light would have traveled 13 billion lightyears ... [More]

oh, i see, thanks for noobing it down for me, lol...well, have this theory ever been tested or is it just what most decide to just go by? But how can we see it if it exploded 13 millions years ago?..thats the most confusing thing to me if it exploded 13 million years ago. and we just now seeing it. that means it took the light 13 million years to get here.

What was out there 701 million years ago?? i'm going to say it because i believe it. God whomever or whatever he is.

Someone said that the universe can expand at faster than light speed. If that were true, wouldn't all visible light be red shifted so much, you would not be able to see it? Let me sum up. The ever-expanding universe theory just doesn't make sense. What makes more sense is that space is not "flat" and not linear. This exploding star happened to be in a part of the universe where space is more compressed, giving the appearance that it is receding from us.

This exploding star happened to be in a part of the universe where space is more compressed, giving the appearance that it is receding from us. You are correct in one thing - visible light often is redshifted to the point you can no longer see it. Light emitted 13 billion lightyears ag... [More]

i wonder if anyone can answer this. when we look at distance galaxies we are not seeing them as they are today, we are seeing them how they where millions or billions of years ago. Now if intelligent life in these galaxies were to look in their rear view mirror towards where we are in space would we be visible to them? or would we not be in existence. No, they wouldnt know about us. They would be in the same predicament as we are in trying to find them. You would think the light from this event would have circled around the universe at least once since then. This light wouldnt circle, in an or... [More]

No, they wouldnt know about us. They would be in the same predicament as we are in trying to find them. This light wouldnt circle, in an orbit if thats what you were getting at. From my understanding the light basically expands "straight". There is always something there. This something may not have anything solid actually in it, but it would still be something...(SPACE) I dont know if any of you have ever seen The Neverending Story but, in it, they fear - "The Nothing". The "Nothing" was still able to destroy anything in its path to leave an empty void. So, my point is...even The Nothing...wa... [More]

I believe that the universe expanded, but it is not ever-expanding. The universe is like a piece of popcorn. It goes back and forth between two stable states - popped and unpopped. So the universe quickly expanded to its present size and then stopped. Someday, it will collapse again and the cycle will start over. Explaining the red shift is a little complicated. I believe the universe is divided into several regions that are separated by rifts - just like the earth is divided into several plates separated by rifts. The closer you are to a rift, the more space is compressed. Objects like quasar... [More]

Great post. I don't know if these would be of any interest, but- Undulant Universe Observational Constraints on Undulant Cosmologies and The Dark Energy Survey Mounted on a telescope in Chile, the Dark Energy Camera will peer deeper into the sky and unveil more galaxies at greater distances than any previous project, including the Sloan Digital Sky Survey. It will collect data on the distances of supernovae from Earth; the large-scale clustering of galaxies; the abundance of massive galaxy clusters; and the bending of light caused by galaxies and clusters of galaxies. Scientists will use these... [More]
