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.

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.

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.

Worth noting that using ctrl+shift+esc will not send a cpu interrupt, so it won’t help if stuff is locked up.

Salt water is a huge pain to work with. The salt would quickly corrode any cooling systems.

A single person can, but not every single person who chooses to is able to. You have to be born in very specific conditions or get very lucky to be able to enact meaningful change on a world scale.

Not certain about the mars trilogy but there is a collapsing space elevator in the foundation series (at least on the show, haven’t read the books yet.)
- Comment on If a Space Elevator became a reality, wouldn't the cable act as a kind of wick for all of the unfiltered radiation from outside our atmosphere? 4 months ago:
I think that depends on how big the tether is tbh. It has to be usable as an elevator so it can’t just be a thin cable. And your scenario is assuming that it would be cut down near the base, if it’s damaged anywhere higher up anything below the cut will fall down to earth.

Ah thanks, I was a dingus and looked up the diameter instead of the circumference. Still doesn’t really matter where you build it. No matter what it’s fucking up a a good portion of the equator if it falls.

By the necessities of its design a space elevator has to reach geostationary orbit, which would make it tall enough to wrap around the planet twice if it fell. Wouldn’t really matter if you built it on a west coast or not.

In the matrix humans were used as batteries, not processors. Although that was the original writing before an exec thought the average person would be “confused” by that

Not true, at least a couple of the but chains, e.g. target, will keep track of you even at different stores.

Well, we have the golden records on the Voyager probes, a similar one on New horizons, and our geo-stationary sats will pretty much last until the end of our solar system. So there will be some evidence of us for at least a few hundred million years or so.

Have you gone and looked at what W3 looks like recently? It’s not a bad looking game by any stretch but this still looks significantly better imo. The vegetation density definitely looks way better, as well as the lighting.

Just for the record, the in game OST was properly done by MG and was great. It was the Official OST album that was taking bits from that OST to make full songs that were very sub-par. The music MG was making us very dynamic in game, and each level had multiple musical phrases that start and stop dynamically during gameplay (this isn’t unique to doom of course, lots of games do this.) in game the music is some of his best work imo, and really brings the gameplay to another level.
Some people have released better mixes of the songs taken and edited from those music clips in the game files to make better mixes than the Official OST album.
