So, I was checking out this exploding star....
http://www.tcd.ie/Physics/Schools/what/stars/EtaCarinae.html
... and I thought "How long until the shockwave hits us?"
Well, it is 8,000 LY away, and to us it happened 150 years ago.
So, that means the actual event transpired 8,150 years ago.
The shock wave is traveling at about 1.5 million miles an hour.
8,000 LY is 47,029,002,985.468864 million miles.
8,150 years is (8,150 * 365 * 24) = 7,139,400 hours.
So, to this date the shock wave has traveled (7,139,400 * 1.5) = 1,070,910,000 million miles.
That leaves a remaining distance of about (47,029,002,985.468864 - 1,070,910,000) = 46,921,911,985.468864 million miles.
Okay, so how long until it gets here?
Well, (46,921,911,985.468864 / 1.5) suggests 312,812,744,656 hours.
In years that is (312,812,744,656 / (365 * 24)) = 3,570,921.
Phew! What a relief!

I read in the paper this morning that they discovered a huge fireball travelling through the galaxies, eating up mucho galaxies etc along the way. It's supposed to be some crazy number like 93 million times the size of our sun, or something like that. We live in a fun place, eh? I didn't read far enough to see how fast it was supposed to be travelling, but I suppose with that size and all, its probably moving quickly per second.

So, should we make dinner plans or not bother?

infinities aren't applicable to the universe. Just as time is not infinate, space cannot be. It's a philosophy thing. If you'd like, I'll give you an example of how infinites can't really be in a physical universe, but only in the mind.
