Edge of the universe -- now you know.

"Most distant cosmic blast sighted." BBC News, 9/12/05.

Scientists report that they have observed light from the probable collapse of a massive star that came from 13 billion light years away . . . .

Considering that in one light minute light travels 11,160,000 miles, how does one grasp the immensity of the distance that is 13,000,000,000 light years?

One light year represents a distance of 60 x 24 x 365 (525,600) x 11,160,000 miles, or roughly 5,865,696,000,000 miles. Now multiply that by 13,000,000,000!!!

The only way the human mind can possibly grasp the immense distances involved and the blinding speed of light is to watch how fast Christmas decorations go up in Wal Mart again after December 26 each year.

One Wal Mart in Ponca City, Oklahoma, put up its Christmas decorations again one year on Memorial Day.

NOW do you grasp how far away that collapsing star was?
