The Most Distant Light in the Universe?
The little smudge in the telescope images may be the most distant object ever seen — a dying star, exploding in what astrophysicists call a gamma-ray burst, 13.065 billion light-years from Earth. Since the Big Bang is currently estimated to have taken place 13.7 billion years ago, the explosion happened when the universe was very young — five percent as old as it is now. The explosion was spotted by several telescopes at 3:55 a.m. EDT on April 23. The light literally came to us from somewhere near the edge of space. The image above came from the Gemini observatory in Hawaii. The one below is combined from several sensors on board NASA’s Swift orbiting telescope, designed specifically to look for these most spectacular of cosmic events. "We’re seeing the demise of a star — and probably the birth of a black hole — in one of the universe’s earliest stellar generations," said Derek Fox of Penn State University. A light-year is a little less than six trillion miles. Do some math, and if the explosion was 13 billion light-years away, it was about 76,000,000,000,000,000,000,000 miles off. “This makes it easily the most distant object ever seen by humanity,” said Edo Berger of the Harvard-Smithsonian Center for Astrophysics. The European Southern Observatory, which detected the explosion too, agreed. NASA scientists think other objects, imaged by the Hubble telescope, may have been farther away — but they weren’t seen just as they exploded. The explosion was of "modest brightness," said astrophysicists, and lasted only about ten seconds. But it was violent beyond description. Scientists say gamma-ray bursts, which happen when stars run out of fuel for the nuclear fusion that powers them, are the "most powerful events in the universe," in the words of Britain’s Science and Technology Council, destroying everything around them for light-years around them. For now, the new find is only known by the name GRB 090423. Poetic alternatives welcomed.

Let’s see – nothing travels faster than light. If that’s true, how did we get here before that light did? Also, if nothing travels faster than light, that’s what we should build spaceships out of – nothing.

With no disrespect to the great minds in astrophysics, The Vedas state that the universe has a definite circumference and coverings of the same elements within it (begginning with earth, water, fire, air and ether, that’s why it’s dark, like the inside of a basketball. There are billions of universes floating like bubbles in a great cosmic ocean. This concept of billions of “light years” is questionable.

Can some math geek comment on this? If this is 13bbn light-years away and we are seeing it now, then it blew up 13bbn years ago. So that means that in 0.7 bbn years it lived, died, and it and us moved far enough away from each other so that it took the rest of the time for that light to reach us? Just how fast was/is everything moving? Does the math work?
Posted by: Andy | April 28, 2009, 5:52 pm 5:52 pm
If space is curved (Einstein proved it), then maybe we’re actually looking back at ourselves billions and billions and billions of light years ago.
Posted by: Peter Searle | April 28, 2009, 5:54 pm 5:54 pm
Correction: the time we’ve been moving apart would not be .7 bbn years, but 13.7, but light has been moving as well for those 13 bbn years.

I wonder sometimes how the people who claim the universe is about 6000 years old because the bible says so explain things like light that took billions of years to get here. I’m sure I don’t want to know the answer, because I’m sure it will make me angry.

I wonder if the galaxy is much older than they believe…
If the light if this is explosion is just now arriving to earth(meaning it happened 13 Billion years ago) then if there are object farther away, we won’t even know they exist because they behind the veil of time.
I watched a documentary on the gamma burst mentioned in the article. Those things are deadly events; wiping out all or a sizable chunk of the galaxy it happened in. If one occured in the milky way galaxy…life on earth would be obliterated in an instant… very scary ,and even more so when there’s nothing we can do about it.

Is this right? 76 sextillion, four hundred quintillion miles? I tried to figure it out. “Since the universe itself is believed to be 13.7 years old”, usually I don’t nitpick, but um what should that really be? Anyway, that’s really far out.
Posted by: BridgetoSomewhere | April 28, 2009, 6:14 pm 6:14 pm
Andy
Interesting question. I think we can only say that there are 13 billion light years between where the object was THEN (when the light left) and where we are NOW (when we finally detect the light). Where the two endpoints were traveling before and after that event shouldn’t affect the calculation.
I was going to say that astronomers could maybe calculate where we were THEN, but of course our solar syatem didn’t exist then.
Definitely mind-bending.

“Let’s see – nothing travels faster than light. If that’s true, how did we get here before that light did?”
The expansion of the universe doesn’t occur at the ‘edge’ of the universe, but everything within the universe (the whole universe) is expanding. In Einstein’s parlance – the speed of light is the speed limit within space-time, however space-time itself is expanding. Therefore for this reason many objects in the universe will be moving relative to the Earth faster than the speed of light. Some of these objects might never be visible from the Earth because their light may never reach us.

76 sextillion, 4 hundred quintillion; not quadrillion. Quadrillion is lower that quintillion. It goes million, billion, trillion, quadrillion, quintrillion, sextillion, septillion, octillion, googol, googolplex.

Matt, I had to do something with the 400. You rounded it off, and they did, too in the article but not the title; I’d say no big deal but its a huge big deal heh. Anyway, that table sat your link stops at octillion. What comes next? Non(t)illion? Dec(a)tillion? Now I know I’m being silly because I will never remember it anyway.

The Earth is not 40 billion years old. You’re off by about a factor of 10. I’m assuming you made a typo. The age of the Earth is estimated to be around 4.54 billion years. The age was determined by C.C. Patterson using uranium-lead isotope dating of meteorite material.

“I’ll like for you to show us where the Bible says the universe is 6K……” Well, I guess if you are using base 10 as your numbering system, that’s wrong, but if you use a huge one, you could make it work, like 6000 something. Please don’t ask me to figure it out. It’s analagous to the decimal numbering system as compared to the hexadecimal system only with a much greater spread.

If a gamma ray explosion destroys everything in its surrounding, why do we the see other bright objects next to it?
Astronomers always think with explosions and black holes–it makes it exciting and allows for metaphysical reasoning I guess.

“If a gamma ray explosion destroys everything in its surrounding, why do we the see other bright objects next to it?”
Answer: While that photo shows other objects in the same field of views, you can rest comfortably knowing the other objects are nowhere near the far-off exploding star. Understand?
Example: Of the stars in the Big-dipper, they are all at very different distances from us. They are not as near each other as they would appear to be.

As a scientist and Christian, I just wanted to clarify the following:
The Bible does not date the origins of the earth or universe. It states simply: “In the beginning God created the heaven and the earth.” This poetic account actually tracks quite nicely with our current scientific knowledge…”13.7 bn year ago, a infinitely compressed speck matter expanded to give all that see.”
Those who claim a “young Earth” based on a gross misreading of the Bible should look to the many pseudo-Christain doomsday cults as warning. Yes, the Bible predicts a cataclysmic end to our world but purposefully does not specify a date (“no man shall know the hour”). Groups obsessed with guessing the unknowable have a bad track record (David Koresh, Jim Jones, etc.) Interestingly, the very laws of Physics also point an unavoidable “end of days.” (see the Second Law of Thermodyamics, heat death).
For those who have never seriously investigated either, it may be shocking to find that Science and Bible are not in opposition. Please remember that the great scientist’s of old- Caprenicus, Kepler, Newton – were scientists because they wanted to see the beautiful fingerprints of God. The sought awe inspiring inspiration like the supernova just discovered.
If you interested, please check out the
About Time: Einstein’s Unfinished Revolution by Paul Davies gives a easy to read explanation about the nature of our universe (curvature, time travel, heat death)

Andy (in his simple way) raises a very profound point. How did we get here faster than the light did if everything was all in one place at the big bang?
Physicists will say that nothing moves faster than light, but they give themselves a big loophole called cosmic inflation. They say that at some time in the past the universe did expand much faster than light. But they don’t know how and don’t know why. I’m skeptical. I’ll believe it when they can explain it.

To all posters: Please differentiate between “Andy” and “andyr.” We are two different people. Just wanted to clear that up. My ways are simple because I’m a simple person asking naive questions. I certainly wouldn’t want to drag others down to my level of understanding things.
Posted by: andyr | April 29, 2009, 9:55 am 9:55 am
As a pastor and a guy very interested in all this cool astronomy stuff, I have to disagree with Theuje. Agreed, nowhere in the Bible is it written that the earth is 6k years old. However, when you take a literal interpretation of the Bible, there is no room for an exponentially greater amount of time. The other problem is, if you believe in 6 literal days of Creation, which I believe in for a host of reasons, it is impossible for things to happen out of order from Genesis 1. If the “light” was the big bang, how could plants begin to grow before the evolutionary timetable currently laid out by science.
Indeed the Bible and Science are not at odds. Bottom line is this: God, when He created everything, far beyond our understanding, created everything we see mature. That means, full size trees, ones that look much older. He created rocks and mountains. He created stars on the brink of explosion, so that we would see them now, even though they look billions of light years away.
God is the loving Creator-designer who imagined this world, created it, and loves it.

If we are so arrogant to think that there is but one “universe”, then we are not thinkers.
Our concept of the universe is what we can see, either by the naked eye or using timed exposure telescope images that receive light from billions of light years away.
To put this object in perspective, we would use a stone dropped into a pond, watching the waves move outward from the center (big bang theory). This object would of course be on some opposite side from that of our point of view.
If the “big bang theory” is correct, then there are an unimaginable quantity of “big bangs” that have, and are continuing to, occurred.
We cast ourselves as universal, that nothing but us and our universe is all that there is.
Astronomers were shocked when the first images from Hubble revealed masses of galaxies (Hubble Deep Field). The concept of so many galaxies was not thought of, because we weren’t thinking of the “beyond”.

I have read that 96% of the universe is made up of “dark matter” and “dark energy” with only 4% being visible. If the visible 4% is spread over a distance of 76,000,000,000,000,000,000,000,000,000 miles, then how much do you think we really understand about even that 4%? It seems to me that only a fool would read 4% of a book and profess to an expert or even have a clear understanding.

The reason scientists know that dark matter and dark energy exists is because they are clearly inferred by the physics that is understood, tested and known to be true. As laypeople, it is a mistake to assume that because you or I can’t understand something that it must be wrong, or can be dismissed, or that experts in the field are ‘fools’.

I’ve read the Srimad Bhagavatam (Bhagavata Purana). There are detailed descriptions of our universe, how it was created, by whom, when, and why. I can’t believe every time I read something on astronomy, the Vedas – the most ancient and complete source of transcendental knowledge, are not even mentioned! So much speculation!
Posted by: Gerald | April 29, 2009, 12:28 pm 12:28 pm
Gerald, transcendental knowledge is by definition supernatural and therefore I’m not surprised it isn’t featured in scientific literature. ‘Speculation’ is the opposite of science. Science is based on theories developed to fit with evidence. Theories are tested by continually comparing them with new evidence. Depending on how theories fit with this ever-growing body of evidence, they are either discarded, modified, or eventually embraced as mainstream science by the scientific community. There is no speculation as you describe it.

I’ve heard this argument may time’s but it is fundamentally flawed. Assuming that god created the world only 6000 are so years ago, with the light from distant stars already reaching earth, then any object greater then 6000 light years away should appear static. For example distant regularly variable object such as Pulsars would not be visible in distant galaxies under such a scenario. But they are so there must be something wrong with your hypotheses, unless of course you’re say god is some kind of cosmic liar.
Rather that argue that god create the universe with the appearance of great age why not simply argue that he actually create it with great age. That the act of creation would have encompassed both past and future events, then move on from there. That would be within his power would it not?

I’m a physicist, also a Christian – also studied the scriptures for many years. All truth is consistent – and there is evidence everywhere that the universe is ancient 13 – 14 BillYrs and the earth about 4.5 – it’s written in every rock, every star, every organism. The 6000 years idea came from Bishop James Ussher of the Anglican Church. He wasn’t infallible and wasn’t a prophet, he made a mistake – he assumed the biblical genealogies of the patriarchs was listed as single generations and complete. He also assumed nothing preceded Adam. Both these ideas are contradicted – even if we only use the bible as our primary source. Most christians think this anyway. I don’t think God wanted to trick us. If anything, everything we learn here tends to increase the grandness of the creation.
Posted by: PeteS | April 29, 2009, 2:15 pm 2:15 pm
SDR, I think science is great or I wouldn’t be reading articles about a distant light in the universe. I just wish scientists would make it a little more known that they don’t have all the answers rather than give the assumption that they have it all figured out and since a NASA scientist said it it must be right.
Posted by: Dyersburg | April 29, 2009, 2:31 pm 2:31 pm
Dyersburg: It is not my experience that Scientists claim to have all the answers. Most I have encountered claim categorically that they don’t have all the answers. However some things are just beyond question from an evidence standpoint. For example, the universe being vastly older than 10,000 years. Scientists will certainly be very forthright when challenged on such things simply owing to the evidence supporting their position. On other matters such as the nature of dark matter, there is considerable disagreement and scientists propose different theories all the time. As far as this article is concerned, there seems very little debatable science there to me.

@SDR – “Speculation” may be the wrong word. “Guessing” might be better! Is not the creation of the universe “supernatural”?
Posted by: Gerald | April 29, 2009, 3:19 pm 3:19 pm
Gerald:
1) I think both “Speculation” and “Guessing” are both equally bad words and not what science is about.
2) The initiation of the universe might have been supernatural – I suspect no one will ever be able to prove that one way or the other since all known science breaks down at t=0 (The Big Bang). However that is not what you seem to be saying. You seem to say that religious literature should be accepted as the truth of how the universe is and works now, rather than scientific evidence. I personally don’t believe this. There are many reasons for this, not the least of which is that there are many different religions and countless different interpretations of holy scriptures for each religion. I presume you disagree with Christians who take a literal view of the book of Genesis for example.
Posted by: SDR | April 29, 2009, 4:07 pm 4:07 pm
SDR – Eventually, science will prove that one religious depiction is correct and others are just fairy tales. Nothing comes from nothing. The Big Bang was a chunk of pure matter, created by God, and made to explode for the purpose of material creation. The point is, there is intelligence behind the creation of the universe, it didn’t just happen by chance or evolution. Science will eventually come to this conclusion, especially after we interact with another intelligent civilization from a distant planet that confirms it for us. will that be sufficient proof?
Posted by: Gerald | May 1, 2009, 12:32 pm 12:32 pm
Gerald: I think we have exhausted this conversation. You have said you believe science is guessing and/or speculation, so it is quite contradictory to now say that science will prove one religion is correct. Also, you seem to accept The Big Bang, but appear confused on the nature of evolution (the theory of how life has developed on Earth, not the creation of the Universe). Lastly it is far from certain humans will ever make contact with another intelligent civilization owing, at the very least, to the vast distances to neighbouring stars. Even if we do, unfortunately that would only count as opinion, not proof. Proof is evidence-based, not simply what someone tells you, alien or not. Best wishes.

Is it possible that the light from this exploding star was traveling faster when the star first exploded that the speed it was traveling when we saw it? Do we know if light travels at the same speed in the area of space the star exploded as it does in our own solar system?
Posted by: D | May 3, 2009, 1:10 am 1:10 am
Every now and then some unknown scientist discovers that something we have believed to be true for a long time is simply wrong. The limits of velocity are an excellent example. Soon it will be proven that the speed of light is not a barrier or limit at all, as it is now believed to be. We already know that light can be bent, and it can even be slowed down, so it is only natural that if we can manipulate light that we can also make it faster. That would make our current “yard stick” for measuring the universe totally unreliable, and completely change our view of our universe.

Thank you James, well said. @SDR – How do you know who your father is? Your mother told you = not evidence based, yet you believe it. Anything created by, used by, or perceived with our imperfect and limited senses will also be imperfect and limited. But, there is evidence beyond our sense capabilities. Also…how do you separate creation and evolution? Once upon a time, the intelligent class of men in the civilized world sincerely believed the world was flat.

SDR — excellent, concise explanation. No, I’m not an astronomer or physicist, but in high school I won a National Science Foundation scholarship for a university summer program in physics. I did miserably — except, for reasons beyond me and my professors, Einstein’s theories. Their *math* gave me fits — but not the underlying concepts. And you explanation seems to be exactly right.
Someone mentioned the Earth being 40 billion years old; drop the zero, and you’re in the ballpark. (About 3.7 billion years old, as I recall off the top of my head, is the most accurate current estimate.)

Why do we even put an age to the universe. When there are billions of other galaxies so further out that there light will never reach us. What if what we are viewing (in some parts of the cosmos) is the far distant future. What if what we are seeing is the reflections of reflections of reflections, instead of red shifting and blue shifting, the future part of the cosmos is green shifting and we just don’t have the optical atomics to visualize these unrealized spectrums.

There is one thing we can all agree upon, there are things in this universe that we will likely never understand.
