Oh, now this is a fun article: Ancient Star Nearly as Old as the UniverseDo you ever wonder what would happen if we were able to travel 13.7 billion light years from here? Would the universe wrap around on itself or is there more out there that we just can't see?

You know... thanks to speed-of-light delay, it's possible that this star has already perished. Still, it's an interesting thought.

Tyris Stark You know... thanks to speed-of-light delay, it's possible that this star has already perished. Still, it's an interesting thought. Actually according to the article the Star is in the Milky Way (our galaxy), which is only about 90,000 light years across (so the light we are seeing is only 90,000 years old which isn't too long for a star). Since we see it currently as a red giant, it is likely still a red giant or a worst a white dwarf. http://www.windows.ucar.edu/cgi-bin/tour_def/kids_space/milky_way_ask.html For my reference on the length of the Milky Way.

There's probably more out there, we just can't see it or go to it. If we could, it would be a scientific break through! Alas, there's that one problem of aging during space travel. Is it me, or did that last statement sound like something from a sci-fi movie? sweatdrop ehhe...oh well...It'd be cool though.

There is the possibility that no matter what our technology, we would never be able to get there. The speed of light is the speed limit... and when you have mass, you can't go that fast. None of that Star Trek warp stuff for now. There very well may be aliens out there but we will never be able to meet them.

sbpoofer Unless they come and meet us!!! Are they already out there??? rofl xd That leaves us with a couple of things to think about: a) they are similar to us technologically and can't break the speed limit of light b) they are so different from us that they have developed a way to get around that, but by doing so they are too alien for us to understand, in which case a meeting would be pointless. It would be akin to trying to speak with a plant. I do think there is life out there... Whether or not we would recognize it as life or intelligent is another story. =D

It is interesting that they say the first generatin stars were all supposed to be so big, and this one which formed right after was so much smaller. I wonder why that was?

SirKirbance It is interesting that they say the first generatin stars were all supposed to be so big, and this one which formed right after was so much smaller. I wonder why that was? My guess would be that because after the Big Bang the universe was not as big as it is now, that gravity condensed bigger stars. Also, at that time there was only hydrogen, helium, and maybe a trace of lithium. The heavier elements are only made in stars after they explode. This would mean that second generation stars have a ring of "dust" around them that can form into planets.

None of that Star Trek warp stuff for now. There very well may be aliens out there but we will never be able to meet them. There is some hope for FTL travel... There have been experiments in which light traveling through specially treated gas has appeared to move faster than the speed of light in vacum (normally what people reference when they say the speed of light). This opens up a whole new realm of changing the speed of light since it is the barrier according to most interpretations of Relativity. http://physicsweb.org/articles/world/13/9/3is an article that talks about it, you can also look up the study by L J Wang, A Kuzmich and A Dogariu.

one: science dating is messed up because there are stars that they think are older than the universe
two:the star may already have gone supernova for all we know and we might never know because i doubt earth will last another 90 million or is it billion years
three: see reason one again

Actually if i remember correctly, there are theoretical particles that travel faster than the speed of light. But they can't slow down slower than the speed of light.
Basically from what I understand the speed of light is like an asymptote... you can get REALLY close to it, be never past it. So going above to below isn't possible and below to above isn't possible.

Aliens could have more high-tech technology or even warp power like from Star Trek, but why meet us? we're the backwash of the galaxy xD
