Thanks for this. I had heard of "standard candles" and knew what they were used for, but didn't understand how they are "standard" in the first place. So if we know distances and we have tracked how galaxies have moved over some period of time, can we figure out where the big bang actually occurred? Was it even a point? Like the space station in the Dr. Who episode Terminus? 😁

Uh, okay. This might get a bit complicated, but I'll try to explain it as well as I can. So, while we can measure the effects of a galaxy moving (like its redshift), we can't measure the actual movement itself. Imagine we are looking at a galaxy similar in size to our own milky way (~100,000 Ly across). Now imagine it is moving away from us at the speed of light. If we messed its position very accurately and then waited 10 years and messed it again, it would only have moved 1/10,000 (0.01%) of its diameter. This is far too little for us to measure. Adding to that, if we use redshift, we can only measure how fast it is moving away from us, and not from side to side. So we know what direction it's actually moving. Only how fast the distance between us is.

Why do we need to know the distances to deep space objects? The universe is expanding, causing all these objects to move in different directions. By taking snapshots of distant stars every year or so, how can we tell what exactly is moving? Near objects - ok, but what about distant stars? Some things appear to be moving, but this is actually because we are moving too. If there is no (0,0,0) point in space, how do we measure the distances without even knowing what is moving?
@cosmic_curiosity2 күн бұрын
Very good question. It's all a matter of what frame of reference you want to use. If we define our universe as our hubble-sphere then we will always be at rest at the center of our universe. We could also move our frame of reference to match yhe CMB. In that case we are moving... and rather fast. But here it can see be proven that for any observe in an expanding universe the observer will alway see all other object move away from them. Look up the bread load universe modle as that explain it very well.

I wrote my masters on solar flare predictions, and yes it is extremely difficult to predict a solar flare event. So all we can really do is to observe the sun until we see the event. It's not that we don't understand the science behind it, it's just not that easy to get good enough data to predict it. We can't just put down weather stations all over the place as we do here on earth.
