What particles are you talking about?

I looked it up. Not only do we take into account the light coming toward us, but the movement of objections away from us. Light has one speed, the objects have another. There's more calculus involved, but I found a calculator that explains it mathematically. LINK
Nice calculations for the radius of the CMB. However the CMB is not the known universe.

sweet explanation...
I assumed that someone with a physics degree would know that the universe is expanding and that you would need to take that into account.

Do explain
That existence in itself proves that life has been happening elsewhere in the universe outside of us.

quote:It's not that simple. We were talking about the age of the universe. If it's just 13.7 billion years old, then particles have only had that amount of time to expand away from the big bang. If we move in one direction (at the speed of light) and are at one end of the universe, then the other end would have the same amount of time moving in the opposite direction. Logic says this can't be more than 27 billion years from end to end. I answered too quickly. There's more to it than that. In fact, what I just said supports that. If I'm moving in one direction at the speed of light... and something else is moving at the speed of light in the other direction... we would never see each other. Because in relative terms, we are moving twice the speed of light.

I know... I'm not arguing that anymore.

Umm, you really need to dig into this a little more.
Celestial bodies aren't moving faster than the speed of light.
The curvature of space-time is EXPANDING. Surely you remember the dots on the expanding balloon explanation to give a general analogy to how something could appear to be moving faster than light?

Does their god mandate they not masturbate? If not, I'll volunteer to go hang out.

Fwiw, I've never seen the expanding balloon analogy.

I didn't think the muslims at NASA even believed in other habitable planets, or other planets, or space, or science.
