Ozzy,
It's all relative. From our point of view, it did take 2 billion
years to get here. But if you're a photon traveling at the speed of
light, time is slowed by time dilation to zero (if you believe
Einstein). Like I said, boggles the mind.

| Hi Scott,
|
| If you are implying that the light we see from 3C273 gets here
| instantaneous. I believe you would be incorrect in that. Btw,
| I dont hold an advanced degree in either astronomy and physics
| so if I'm incorrect perhaps someone else can enlighten me. The
| whole concept of light boggles my mind ever since I took up
| astronomy. I was fine with it when you just turned a light bulb
| on you got light lol
|
| Here's another example, super nova 1987a for instance, if lights
| trip was instantaneous then we would of miss that SN by 160 000
| years.
