Researchers from NASA's Goddard Space Flight Center in Maryland believe they have captured a glimpse of the first stars that lit our universe.

Do you think they're right? I'm a little skeptical. Based on the article you posted, it seems like they're saying they have found radiation and they don't know where it came from, therefore it must have come from those first stars. Isn't that a little irresponsible? Isn't it more likely that the radiation they measured came from a more recent, or even a current, source?

From what I've read, it could go either way. What they describe certainly COULD be true, but it also could be flawed information (as some of their critics suggest).
For me, the joy is in living in a time when this kind of thing is possible. Even if this particular group didn't quite get it right, we live in a world where it's possible that they did get it right. I can't get over how amazing that is.
Is radiation's age measurable, and if so how is it done? What I mean is, can one tell the difference between the remains of a lot of old radiation, and a little new radiation?
I'm afraid this is out of my league to even ask intelligent questions about, my cousin is the astronomy buff, I couldn't even bring myself to watch the last Star Wars movie.
I agree. Whether this particular research is accurate or not, it is exciting to know that we live in a time when data is being collected that could eventually describe the earliest ages of the universe.
