| Halfway across the universe? http://www.cnn.com/2008/TECH/space/0....ap/index.html Apparently scientists know exactly how big the universe is now. |

Aren't gama-rays the horribly intense radiation beams that will melt everything? I think I saw something about it on the History Channel's The Universe show. |

OK, so by my calculations, which could be wrong, the blast was 442,500,000,000,000,000,000,000 miles away. Can anybody say roadtrip? |

| Gamma rays consist of high energy radiation (similar to x-rays) but produced by decay of radioactive materials (like the Uranium in a star). Gamma rays are used to treat cancer and don't melt everything.

| That has nothing to do with the type of radiation....just the quantity and how it relates to temperature. Since most stars are at quite a distance from our planet and radiation is emitted isotropically and is inversely related to the square of the distance from the source, our risk should be low. BTW, the radiation below your feet and in your body is imparting energy to you right now, but not enough to "cook" you. Last edited by JeremyH; 03-24-2008 at 07:13 PM. |

That means it exploded along time ago. Dont know the exact calculations but do you guys realize how long it takes for the light just to get here from that far away? Its nuts.

I think it's time they turned the telescope the other direction to see what's ahead of us rather than worrying about the past. If we / this universe is still expanding from the big bang? Makes since that things we are doing now are already in the past and we are all living in a present that is also the past. I mean if they were to send a rocket in the other direction fron the past they are looking at, it would make sense that that rocket would be traveling into the cosmic future, which we have not gotten to yet and never will. No one ever said we were on the outer most part or even close to the big bang. So travel into the future could be possible???? But who cares our time is short here anyway. Really short according the the numbers they are counting by the universe would be about 15 bilion light years long and growing each second. I'm not sure of the rate of growth but it makes since it's still growing. Last edited by JIA's Dad; 03-26-2008 at 02:21 AM. |

Yeup. ...and to think that I'd planned to make a pit stop at the star I had dubbed "Midway" on my journey. |
