Curious what will happen to prices in these zoom towns once people return to office work? Wouldn't it be more prudent to shop around in areas where we know people will return in a year or two?

Ideas are cheap. I started working on slack before slack and on aws before aws. Neither have been executed through to the end.

Ok, thanks for clarifying - indeed i seem to have had quite a few misconceptions. But from outside the universe, are things inside of our universe moving faster than the speed of light due to our universe expanding, and as such, things traveling at the speed of light when seen from the outside are traveling at the speed of light + speed of expansion?

Thanks for this - will read more in the two terms.

Very interesting.

So the I wonder if everything expands along with the universe, does it mean that from outside, things moving at the speed of light in our universe, are potentially moving at speeds greater than the speed of light within our universe? If i was watching from outside, a rectangle moving at the speed of light in our universe, would one of its edges be moving away from me at the speed of light + the speed of expansion? If it makes sense.

Interesting analogy. So in effect to someone “watching” from outside our universe anything moving at the speed of light in our context, is moving either faster or slower than the speed of light in their context. Since the ballon and everything inside is expanding it means that either things are moving at the speed of light + speed of expansion, or speed of light - speed of expansion, when watched from outside. Assuming that everything expands along with the balloon. If I understand this correctly, and according to:

“Due to the expansion increasing as distances increase, the distance between two remote galaxies can increase at more than 3×108 m/s, but this does not imply that the galaxies move faster than the speed of light at their present location (which is forbidden by Lorentz covariance).”

But from outside we can move faster than the speed of light? Sorry having trouble getting my head around this.

All right hackernews. Genuine question, not sure where else to ask.

If galaxies and stars at the other “end” formed out of matter resulting from the big bang, just as the matter we are made of, how did we get here at the same time that that matter got there?

Is it because speeds faster than light are possible, and around the big bang all matter was spread near instantly at that speed? I don't understand how matter of the same “kind” was spread throughout the universe all at the same time without traveling at speeds greater than the speed of light. Because if we watch the ”opposite” direction from where the big bang occurred we don't really observe matter in a state closer to its original state, or parts of the universe in radically different states - which should result from that matter traveling further than the matter we are made of, as for us to now catchup with light that is “younger” than that towards the core of the universe. Am i missing something?
