Aside from the reasons u/Pinkratsss mentioned, which are good, it’s not really meant to think about the blackhole’s “current” size. The problem is that time becomes a really nebulous concept when you get out of our day to day lives and start talking relativistically. There is no “now” in any sort of absolute sense. There is no universal clock we can reference. Even though that light was emitted some 12 billion years ago, from our frame of reference the black hole does not really exist in any other concrete way “currently”. The only meaningful way to talk about it is as it appears to us now. While there is no absolute “now”, there is a well-defined “now” in every reference frame, and in each reference frame, things that are seen happened as long as ago in years as they are distant in light-years. Even Nice 2020 Jack Flaherty Throws Gas Shirt though it took some 12 billion years for the light from that black hole to reach us, it’s not really accurate to say the light is from the past.

Or put another way, asking about the blackhole’s “current size” is functionally equivalent to asking what it will be like 12 billion years in the future. Clarified my language based on critiques from u/wonkey_monkey. Thanks for the in-depth discussion. The core issues are that nowness is ambiguous and inherently dependent on a frame of reference. Furthermore, the “current” size of the black hole is something we cannot witness or interact with in any way (at least for 12 billion more years). The only meaningful way to think about the black hole is as we see it today. This is why the article refers to it as “the fastest-growing black hole in the universe”, not the “fastest-growing black hole 12 billion years ago”. No, it isn’t. It happened 12 billion years ago because it’s 12 billion light-years away. In some other reference frame, it happened 5 billion years ago and 5 billion light-years away, and in yet another reference frame it Nice 2020 Jack Flaherty Throws Gas Shirt happened one second ago and one light-second away – but that’s not our reference frame.

You’re on to something. It’s that our moon is larger and closer than average for a planet this size, so we get tidal forces that stabilize the Earth’s rotation and preserve its tectonics and magnetic field, which are all pretty important for life to continue. As for how closely the sun and moon are the same apparent size, that is a coincidence. In the past, the moon was closer, and we could only get total and partial eclipses. In the future, it will have receded enough that total eclipses are no longer possible, and so we will only get annular and partial. But maybe it’s no evidence of a creator, it’s just evidence of this is how life forms elsewhere. So that’s why we look for Earth-like planets because it’s the only thing we know that has the potential to Nice 2020 Jack Flaherty Throws Gas Shirt support life. So maybe for life to appear, the planet must have tidal forces, magnetic fields, and everything you said.
