We are looking 13.1 billion years in the past. :mindblown:

By using data collected by the Hubble Space Telescope and observations from the Keck I telescope at the Keck Observatory in Hawaii, astronomers have now confirmed that the galaxy designated z8_GND_5296 formed within 700 million years after the beginning of the universe, making it the oldest and most distant galaxy ever verified.

Because the galaxy is so far from Earth, scientists were able to observe z8_GND_5296 as it would have appeared about 13.1 billion years ago. [How Galaxies are Classified by Type (Infographic)]



I don't want to be that guy but how the frick could they possibly know that?

They have no way of knowing how old the universe is and you can't calculate how old a galaxy is just by the amount of electrons your little telescope sucks in or whatever the frick they do

More people need to start being that guy instead of just sitting back drooling from their mouths at all of this crap

Light travels at a set speed through deep space, so if you can determine the distance between the observation point and the object being observed, the distance in light years would be equal to the number of years ago that light was emitted due to the fact that we can't see the light from an object until it travels the vast distances to reach the observer.

Yes I understand how the telescope works and how they got the light and estimate how old that galaxy may have been when it sent those photons and what not but that still doesn't explain how one could know when the universe started.

you definitely can calculate that. Just like we can calculate that it takes 8 minutes for light from the sun to get to the earth, theres no reason to no be able to calculate that the thing is atleast 13.1 billion years old by how long it took the light to get here. However this was about the point where it went from me owning to physics in college to it kicking my ass.

So, what percentage of people in this country can really comprehend 13 billion light years, either as a measure of time or distance? Probably about the same percentage as LSU fans that knew Furman was in South Carolina!

Would it be theoretically possible to see far enough back in time to immediately following the big bang? I think we'll come up with something to see that far back one day and all we'll see is a troll face.

I don't understand how we can see what this galaxy looked like 13 billion years ago and not see how much more dense the universe was at the time. IE, if the universe is constantly expanding, and it takes 13 billion years for the light to reach us, could we also not theoretically find the light that the milky way put out 13 billion years ago?

wed have to be 13 billion light years away looking towards the milky way for that to work. And since we are in the milky way, thats not happening.
