Re: JWST spots giant black holes all over the early universe
#43Can someone who really knows this stuff clarify my understanding? I've been given to understand that black holes remain a physics theory that has not been directly observed or proven. I thought that we had a fair amount of observational evidence that suggests their existence, but no "smoking gun" proof of it, and that these types of "observed a black hole" articles are a little misleading - that in reality, what was…

There are several smoking guns:

Wouldn't that be incredibly hard, considering that the players perspective is disconnected from the units? I observe my base and order a group of units to go to some place on the minimap. I see them moving along on their way, and decide to scroll to them. Only to realize that they already arrived and got massacred by the enemy. I go back to my base only to realize that it was destroyed ages ago (in its frame of refer…
In ordinary strategies you already have an assumption of immediate information transfer from unit to player - you see what each unit is seeing. This can be kept so you will see you units moving in real time but as things get further from your units on the map, the older info about them you get.
EDIT: Also if a unit traveled close to C away from a friendly unit, and then back, whos reference is real?

#47So this is one of them "shower thoughts", you know, those stupid things you think about while working on something else.That is, purely science fiction. Can an analog be drawn between galaxies and solar system creation theories, with several orders of magnitudes in time required for formation due to scale difference. That is, the galaxies we see with their billions of stars are actually young proto accretion disks. w…

My understanding is that a particles, like photons, don't have wave shifts. That's an emergent property of many particles

> internally consistent limits on what the player can know Interesting thought. Can you expand? What do you mean by this?
Not the original author but my first interpretation is that this means, if it were in a video game, it would be a way to self-reinforce "fog of war" where you can only have extremely local information and you don't want extra information to leak to the players.

You can estimate how close to the event horizon the disk is based on how broad the spectral lines are. The part of the disk that is coming towards you will be blueshifted and the part of the disk that is rotating away will be redshifted. From that (which is independent of the overall depth of the potential well) you can figure out how fast the disk is rotating. And from that you can figure out how far away the disk is from the black hole.
