NASA Finds Most Distant Object in the Universe to Date

[deck]

[citation][nom]darkavenger123[/nom]I can never understand what the excitement is about. It is basically a blob of pixels. What can you make out of it??? Nothing. So the universe is x billion light years old or x trillion light years old. So???[/citation]

Agreed. We need more articles about smart phone sales.

[citation][nom]IndignantSkeptic[/nom]It seems your views are not based on scientific theories but on religious theories. That makes those views highly possibly incorrect, invalid, and dangerously irresponsible. Your views are not appreciated by me so if you wish to not offend me further then you will stop polluting the discussion with further such misinformation.There probably is no pilot in the cockpit and if we don't put someone there soon then something very bad could happen. Some peoples' insistence that there is a pilot in the cockpit when they don't even know that, is dangerously irresponsible and such people should probably be charged with negligent homicide for that.[/citation]

Ahh, but there is a cat in the box. Now whether it is dead or not ...

If this is 13.3 billion light years away, how can the universe be only 13.7 billion years old? That would mean it would have had to move 13.3 billion light years away from us in only 0.4 billion years.

They say at the Big Bang matter was traveling faster than the speed of light, but only for an instant. But how much faster and for how long? Because it would have to have been many times the speed of light for quite a while since gravity would also have to have time to slow it down to achieve a 13.3 billion light year distance in 0.4 billion years.

If it was going faster than the speed of light, which isn't supposed to be possible. Wouldn't it go backwards in time? In which case it would be traveling away to before it was created. In which case the Big Bang would keep reocurring as it reached the point of the Big Bang and another copy of itself would keep being produced an infinite number of times.

The most reasonable explanation is that either the universe is far older than they currently think it is. Or that galaxy is closer than they think it is. I'd say it is likely the former. Since it seems that every couple of years scientists increase their estimates of the age of the universe.

[citation][nom]surfer1337dude[/nom]Nothing is suppose to move faster then the speed of light from my understanding of physics.[/citation]

Nothing with mass can move faster than the speed of light. Space itself can expand faster than light due to quirks in the expansion of the universe.

Some of these replies?! Didn't anyone go to school?

Example:
Speed of light = 299,792,458 m/s or ~300,000 km/s
Distance to our Sun ~150,000,000 km
Time for light to travel from the Sun to the Earth (~150,000,000 km / ~300,000 km/s) = ~500 s
~500 s / 60 s/min = ~8.3 minutes or 8 minutes 19 seconds

If the Sun suddenly went 'out' or 'exploded' we wouldn't know it for over 8 minutes. Therefore, all we can see is the past and measures from ns to minutes to billions of years.

It's a very safe bet that all of the stars in MACS0647-JD are now extinct and there probably are replacement stars from the supernovae and gasses left over, but what we're observing is no longer present. Most stars have a lifespan of 1~10 billion years (dependent upon mass; bigger = shorter lifespans), and yep a miniscule fraction can survive >13 billion (oldest one found, HE 1523-0901, is theorized ~13.2 billion).

OR

Some folks religiously believe the world and the universe is 6,000 years old by ignoring all science and belief based.

OR

The Holographic Principle in which none of this 'exists' (M-Theory/Sting Theory) and all 'we' are is an elaborate SIM living out our 'lives' on a black hole or in some elaborate computer.

[citation][nom]mhawk13[/nom]My god.... you are so wrong on this and yet you try to appear so all-knowing that I had to comment here. Light always travel the shortest path from a to b, but gravity is the bending of the spacetime itself. Read more about General relativity before commenting such things. Or perharps you are just trolling?[/citation]

And I'm the all knowing? Oh it's the forum police, look out people.. First, i've read alot about general relativity, obviously I don't have a p.h.d, but I'm pretty sure light doesn't travel the shortest distance from A-B, I think your thinking of electricity traveling through the path of least resistance. Light can be refracted and bent, if it couldn't then you wouldn't be able to see. Who is to say how many times the light is being bent on it's trip from 13.3 billion light years away, even a small refraction from gravity, or even any kind of material it could be passing through could drastically alter it's path.

[citation][nom]SirTrollsALot[/nom]***Aliens pass by Earth and are thinking about communicating*** Hey Bob, did you just intercept that Toms post about that 13 billion year old galaxy? And how stupid some of the comments are? Yes Larry, screw them they're idiots. I heard this part of the galaxy is full of them....And you wonder why Aliens dont bother to visit us.[/citation]

Maybe you guys are just visualizing it differently then me. The only way I see the age of the universe being 13.75 billion light years old is if we are either right on the edge of the universe, or directly in the center, which I doubt we are directly in the center. So I'm not saying that I am a super genius or something, but if you could please draw this for me, or explain it so I understand it the way everyone else is, because when i try to visualize it, the math just doesn't make sense to me.

[citation][nom]fazers_on_stun[/nom]I doubt they'll be able to spot things much further back -- IIRC the universe was opaque to EM radiation for quite some time after the Big Bang..[/citation]I can't remember what I had for breakfast let alone 13.7 billion years ago 😉

Not sure where you read that...

Second, SPACE is expanding at an accelerating speed, and is expanding at the same time light is traveling, ever increasing the distance it must travel. That's why we can see stuff 13 billion light years away.

Third, I have an old book from 1987 that says the universe is approximately 15 billion years old, so I'm not sure why you think they change the age of it every couple of years. At most, they are making the time more accurate as we build more precise measuring tools.

[citation][nom]nebun[/nom]not really....in order for something to take life there has to be a number of processes that take place....there is no way for anyone to really know what happened and how it happened...the BIGBANG is a theory which has yet to be proven true...the same thing goes for the EVOLUTION theory....sorry but i can't really help you, if i could i would[/citation]A couple of replies have already pointed out that evolution is FACT. There is a good YouTube channel where a very knowledgeable person named AronRa http://www.youtube.com/user/AronRa

Look back at his videos and you'll see some extremely detailed information on the fossil record. He even shows us the missing link, a fact that to this day, is still denied by creationists. Ignore his religious attacking videos if you are offended, just view the educational ones.

[citation][nom]upgrade_1977[/nom]Hey, everyone used to think the world was flat, just cuz everyone thinks they are right doesn't mean they are right. And also, common sense doesn't just get thrown out the window because you want it to. Please explain to me how we can see 13.3 billion light years in two opposite directions? The age of the universe is not relative to our viewpoint. If all those scientist's are right, then we would be on the very edge of the universe. and you we would be able to see the edge of the universe, as it would only be .45 billion light years away. Neah, I think "ALL" the scientists who believe that the universe is 13.75 billion years old are just wrong. I don't care how many of them who believe that, you don't just throw common sense out the window. I actually believe the universe is infinite, if if there was a big bang, then our whole universe is probably just on the inside of a black hole, or maybe there is just billions of big bangs and space separates different universes. Honestly, where do scientist's get these calculations, like how many particles are in the known universe, lol, how could they possibly know that? If they are right, then they would have all the answers now wouldn't they. Believe whatever you want though.[/citation]
don't be a damned fool...

2 seconds of searching yielded the above video which explains your concept confusion for you upgrade_1977

there are gobs of great videos for layman out there on this... hawking, sagan, discovery channel... etc. youtube is free so your continued blatant ignorance has no excuse

Our current theories about the Big Bang depend upon something called inflation. Inflation expanded the size of the universe exponentially in a very short period of time. Nothing can travel THROUGH space faster than light, but there is no law that limits how fast space itself can expand.

Think of a balloon. Draw a few dots on the surface of the balloon and then blow air into the balloon. Can you envision how the dots expand away from each other? From the perspective of each of the dots, it seems that all other dots are moving away from it and that it is at the center of the "universe", but that's just a matter of perspective. There is no center and no edge to the surface of the balloon.

Scientists have actually decreased the age of the universe over the years. That's because without inflation, which was developed in the 1970's, the universe would have to be much older for other galaxies to be so far away. Plus there is the problem that the cosmic background radiation looks the same and the universe looks the same no matter what direction we look. There simply wouldn't be enough time for light to travel and information to travel that kind of distance if not for inflation, so your question is a good one and something that scientists also asked.

These theories, including evolution, are our best answers to the questions being asked. Evolution hasn't been directly observed, even with thousands of generations of fruitflies, we've never seen a species "evolve", yet it is the best answer we have and it fits our observations in the best manner. There are still questions and unknowns, but no observation rules out evolution. Theories cannot be proven as fact, they can only be proven wrong. Still we have no better explanation than evolution currently, likewise with the Big Bang.

 

[BrendanS]

A scientific theory is "a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.

The big bang theory has so much supporting evidence that the suggestion that it will be overturned like the flat earth idea is totally incorrect. It may be fine tuned and refined as knowledge increases but the evidence is abundant that the universe expanded from a central point - the big bang.

FYI - The universe is believed to have been opaque for only around 380 thousand years so there is still 400 million odd years of room to find a more distant/older object/galaxy!

Technically however the oldest light in the universe from just after the universe became transparent is now so old that it is detected as the cosmic microwave background... everywhere around us right now and throughout in the universe...

Oh and just to mess with peoples minds further the Wilkinson Microwave Anisotropy Probe has determined the curvature of the universe is likely to be flat... not the earth but space throughout the universe itself...

[citation][nom]drwho1[/nom]"Since the image displays the galaxy as it existed 13.3 billion years ago, it provides an unprecedented view into the beginnings of our universe as the big bang is theorized to have happened about 13.7 billion years ago."So how exactly NASA took a picture from a time where there were no cameras in existence, when it is still hard to take a still picture from a moving object today.just saying....[/citation]

You troll!

 

[mamailo]

[citation][nom]cookoy[/nom]Will we ever see the light from the Big Bang itself???[/citation]

Yes We do.
Is called cosmic microwave background radiation.Is not longer into the visual spectrum because has been red shifted by the expansion of the Universe but is originated from the Big Bang.
