How do we know that the universe isn't dead? Think about it, every star we see takes billions of years to see us. Even the ones we see as alive right now aren't. Is everything dead, and we're just waiting for the death to catch up with us?

Stars are constantly bieng created in Nebulas, so it would be unlikely that they are all dead although nice theory.

stars may be created by nebulas, but the time it takes for the light from the farthest star to reach any telescope on earth(light cant travel any faster than light travels) its already bin millions of years when we look at the farthest stars we can see so technically they are in the future and we are in the past if u agree with the "big bang theory" , to think any deeplyer into this would just mind fuck you

it isn't that they're in the future, we're just seeing what is happening to them after it happens.

The concept of "future and past" as set in accordance with time is false....Time as we know it is nothing more then a man made idea based on how fast the earth rotates...Did you know where all going through time at different rates due to our velocity and pull of gravity...It will actually make you perceive the world differently then to someone else...Time Dilation

even if there was no other reason why that's not the case, apply descartes's reasoning to it- cogitas ergo sumas .. i don't know any latin haha 'it thinks, therefore it is' was what i was trying to say

the closest nebulae is 650-700 light years away, how do we know that isn't dead now? because of everything we've researched telling us its not, or because something unseen from human experience happened? im high again, so who fucking knows.

I think with the limited amount we have discovered about the universe there could be just as much of a chance of either one.

You can't even physically see all the stars.. simply because they're so far away, you the light o the stars hasn't even reached earth yet. If you would see all the stars in the universe at night, the sky would no longer be dark.

Hmm, makes me think of all the planets that have died already. I wonder how many planets with evolved life have died out and how far they were able to make it(whether it be in years or scientific achievement).

There are about 60 galaxies within 2 megaparsecs of earth which is roughly 6.5 million light years. Some of these galaxies can contain up to one trillion stars (Andromeda). Others can contain smaller amount of stars like Canis Major Dwarf galaxy which has approximately 1 billion stars. The life of a star can range from millions of years to trillions of years which is true in the case of brown dwarf stars, which never really became fully fledged stars in the first place. A star the size of the sun will last for around 10 billion years.
There is no possible way that every other part of the universe has used its energy become nothing but darkness while our little solar system is still going strong.
oh and by the way the closest starlight doesn't take billions of years to get here, light from Proxima Centauri takes about 4. Keep positive knowing our universe has plenty of more time, and maybe somebody in a differnt galaxy is looking back at ours when you look at the sky

While it is highly unlikely, there is no way you can make the statement you did. Remember, unless you can prove something 100% without a doubt, dont make statements stating otherwise. Theres always a slimmer of hope.

 
 
Mon, 12/10/2012 - 4:51pm

Im Pretty sure that you can make that statement if you agree with the Big Bang...Which new and mounting evidence even within the last month has proven it to be more correct....Plus string theory......But i do concur, you can give absolutes either way if there is no absolute..

Just like stars die, they are being created. In a few million years if you looked up, the sky would be completely diferrent.

it depends on how fast the death is moving in relation to the speed of light. and time works differently in certain types of space and would apply the the light traveling through it. if "the death" is faster than the light we see, than we are just the lucky ones on the end of a universally destructive chain reaction of events? It sound way to farfetched to me. Another prime example of the dream our planet is more important than it is. Maybe one day if can evolve to that point but for now were just a rock thats probably gonna keep on spinning.

OR.....

death is an invention of mankind, it is a completely ambiguous term meant to put a label on something we can't understand or even comprehend. All we can subtly grasp is that a change of state has occurred amongst the individual, we cannot determine whether their is afterlife, nothing all together, or (most likely) something we don't have the ability to fathom.....

THUS...... saying that the universe and its inhabitants are dead means essentially nothing, your just labeling it as a remaining or existing entity that is altered its state of being into something we cannot understand

I very much doubt that the universe is dead. When a star dies we can still observe there supernovi from Earth. It may take dozens or hundreds of years to reach us, but we know when a star dies based on how it explodes or collapses, and its position in the Universe. On the bright side, a supernova scatters the minerals and elements we are all made of, and triggers the formation of stars in other nebulas where dense clouds of gas are already condensing into the beginning stages of planets. So I don't think the universe will be totally dead for a long time to come.

Life and Death are terms that humans have made up to describe the universe. The dichotomy does not actually exist. "Death" does not have the opposite, "life", in reality. Only in our definitions. All human philosophizing is the manipulation of terms using a primitive form of communication. Enough with language, bring on the telepathy! LSD! haha

Enough with the stupid astronomy lectures. No one came here to have you repeat what your teachers told you. He is asking if we live in a dead universe. Are you dead or alive? If you are alive, than the universe around you is alive. The universe feeds off of direct experience. If you did not have a direct experience of this universe at this moment, It would be dead, to you at least. So as long as you are alive, so is the universe, because the universe is actually inside you, not separate from you. No need for astronomy, the answer is common sense. The stars are not trying to see us, We are trying to see them. To answer your other question, Live bacteria was actually found on an astroid sample, proving that the building blocks of life actually came from impact. Stop looking outside of earth. Nothing interesting is happening in space. The most amazing things are happening on this planet. If you can look around you and see the life in everything, You wouldn't ask this question. Death is not catching up to us, We are approaching a launch into another dimension, and we are catching up to IT. Death is a privilege. What do you know of, that Can live for 100 years, then go to another dimension? Only living things can. Stars and planets don't go anywhere, But it seems as if we are headed somewhere.

Yes, Much of the light from stars we see are dead, but what about the stars that are being born? Just because we can't see them doesnt mean they aren't there. Right?

The "life" of the universe can easily be modeled using a number of laws, theories, and observations. Firstly, the Second Law of Thermodynamics states that heat can only spontaneously travel from a hotter object to a colder object. This means things will tend toward an energy equilibrium and energy will distribute itself evenly across the universe as time goes on. Since we know there are hot and cold points of energy density throughout the universe, like our Sun, for example, we cannot say the universe is dead, or even close to dead for that matter.

Another good principle to examine is the nuclear stability of elements. All matter wants to eventually fuse of fiss into Iron, the most nuclear stable element. Since we can still find almost every element except the extremely unstable ones, it would be safe to assume there is still plenty of time left for the universe.

Going a bit deeper, the lifespan of a Proton can be used as an indicator of the lifespan of the universe. As it stands now, there have been no confirmed instances of Proton Decay, which would indicate to many people that protons have no half life. Some scientists believe, however, that the life span of a proton my be finite and related to the very existence of the universe itself. To be sure, if all the protons in the universe decayed, and all matter destabilized into energy ripples, who is to say there is a universe at all?

Lastly, and arguably most importantly, Einstein's theory of General Relativity provides us with an excellent foundation to estimate things on a cosmological scale. For many years it was thought the universe was still a static body, neither expanding nor contracting. We now know that the universe is not only expanding, but its expansion is accelerating. There are a few theories concerned with why this is happening, but the important thing here is that eventually, all objects in the universe will be moving so fast with respect to one another that no light will be able to pass between them. In fact, the observable universe is shrinking with every passing second, and eventually nothing will be observable at all. This version of the Universal Death is known as the Big Rip. Luckily for us, it would seem this isn't going to happen for many more billions of years, so there's still time to smoke one more bowl.

I've pondered this myself, I came to the conclusion that we exist in both states, yet only one is truely real. The only way to determine if we have died or not would be to look at the universe from an alternate perspective. It's allot like Schrödinger's cat. Google that if you don't understand this.

stars dont take billions of years to reach us, the closest star takes 4 something years for its light to hit us. Im sure there are stars out there that have died long before the light even reaches Earth though.
