Most data centers use evaporative cooling, not closed circuit water cooling.

It's more accurate to say that gravity bends spacetime. The light we see being bent around a black hole is a consequence of that, and is evidence for time dilation as it is also evidence of space dilation. And (being extremely pedantic here, I know,) gravity bends spacetime and light travels through that spacetime in a straight line.
Being in any gravity well will slow your time ever so slightly, by the time you die your feet will be about 100-500 nanoseconds younger than the top of your head due to being closer to the earth!
I think the balloon analogy does not work well here. As far as we know the big bang was the start of our universes spacetime. There are plenty of theories on what might have happened "before.".
Here is a good playlist to get you started on learning some more info.

And this video from that playlist is directly related to this discussion.
The CMBR was the first light that could ever actually go a long distance in the universe, as before that the universe was opaque plasma. When the universe cooled to a threshold it the. Became transparent to light. This light was released in all directions at all points, which is why we still see it today. It will be detectable until the universe's expansion speeds up to a point where it outpaces the speed of light.
There are some patterns in the CMBR but only due to density fluctuations. A fascinating topic to look into is the Baryon Acoustic Oscillations. Small quantum density variations that were expanded rapidly as the big bang started going into overdrive that have shaped the universe on an immense scale.
I don't have time to answer every question you have sadly, and I'm just someone who really enjoys learning about this stuff in their free time. The channel I mentioned has videos on all of this. I highly suggest you start watching those if you actually want an in depth understanding of this.
Yea, all the time. It's like one of the first things engineers program.
Someone else already replied probably better than I can, but this is one of my favorite subjects to study.
The big bang didn't really start in a place, it happened at a point in time. As we look at all of the galaxies around us (minus the close ones we are gravitationally interacting with) they are all moving away from us, so either 1) we are exactly where the big bang took place (vanishingly unlikely) or 2) the big bang happened everywhere and all of space is expanding from that event.
We can actually see the first light ever released in the universe (not from the big bang, as the universe was a dense plasma for the first ~400,000 years until the recombination era) as the cosmic microwave background radiation. And it is (relatively) even in all directions, minus some minor temperature variations.
I highly suggest looking at a channel on YouTube called PBS Spacetime. They have videos going back years and years that dive into great depth on all of these topics!
Exactly, there will be causally disconnected pocket universes in the future. I'm thankful we still live in a time when we can see the rest of the universe. Creatures alive in 100 billion years might have no way to figure out how the universe started, or that there is anything outside of their local cluster at all.
Almost assuredly it can, I think it broke or went into a failsafe or something.
It's worth pointing out that evolution sometimes will just randomly evolve traits that don't really help a creature survive more, it just doesn't make it worse at surviving.
They will remain there until content creators they regularly watch and enjoy start moving. Mamdani is not that. No one is going to be creating a twitch account just to watch this, nor would they do it for some much smaller platform they've never heard of. Mamdani is not the one that will get people to move to new platforms, at least, not before he gets them more interested in the first place. Young people like him specifically because he reaches out to them on a personal level on platforms they actually use.
If you're trying to reach people, you need to go where they are.

Simple, they are more expensive per what cooled than evaporative cooling. Especially when a lot of data centers under report the amount of water they are using.
