"Eventually, the universe is going to die. It's not going to be soon, but it's going to happen, and when it does, our top priority should definitely be to have a computer that can survive it. Theoretical physicists have speculated that we can do this with something called a time crystal, and they may have just figured out how to actually make one."
I don't understand how the laws of physics could be different in another universe. It seems like physics are a by-product of matter.
Actually in most current models of the universe it's the other way around. The big bang was a big mass of potential that became something as it exploded out from the center and after that explosion our universe imposed half lives on the product of that explosion that created the first subatomic particles and then further imposed rules and limits such those parts assembled to form matter and at that point our universe could really define the laws by which substance exists within it.
Think of it like a canvas, you can always paint it anyway you like but in the end the painting is defined by the boundries of the canvas and it's texture and preperation to take up the paints. parallel to our universal canvas may be hundreds or even infinite other canvas in this gallery multiverse. Some oval, some circle, some square and others rectangle, there may be some spheres and tetrahedrons, the occasional tesseract, or klien bottle. Each one defining by it's shape and preparations how the universe within it unfolds. Are they watercolor, acrylic, or oils? Maybe they are just charcoal on white backgrounds, or pastels, maybe the backgrounds arn't white.
There could be entire universes of antimatter, or universes where dark matter was never an option and the skies of a billion times as many worlds as our universe are glowing brightly at night with the light from four times as much matter in the universe forming stars and nebulas to glow.
Perhaps there are whole universes where everything is made of photons and this seems to be a universe sized hologram.
More than likely there are universes so weird we can't imagine them because there is no frame of reference to start from based on anything we know. And some day we may walk outside and between universes and even shape them like craftspeople who create the canvases artists paint on. we could merge them and split them sculpt and form them and then slumber whilst the universe spawns beings that struggle and climb until they too walk amonst the multiverse and we meet. Children of seperate universes, might they even shape the creation of our universe as they emerge from theirs that we might have created each other, no one promises that time is linear outside of our universe, and some even question it in here as well.
Boggles the mind, no?
It boggles our minds because, unfortunately, the way our brains were developed was thanks to our evolution from basic amino acids to what we are now on a little rock in an insignificant speck of a corner in an universe we presently know has no boundaries. The ways we can potentially experience what "this speck of a corner" through our present five senses (and in addition, the radiation-detecting tools at our disposal and our feeble attempts at mathematics) has to offer is probably an unimagibly small fraction of what is really out there. We are vastly out-boggled!
If we want to truly understand the Universe and more, we will have to design far more efficient vessels to accommodate a radically evolved consciousness as well as incredibly advanced paradigm-shattering raw computation power. Heck, this may require a completely new states of matter we haven't begun to conceive as of yet. I wouldn't say it is going to be impossible, but to successfully get there, we'll have to cry in despair a few more times while contemplating suicide involving the entire civilization.
Maybe this solves the Fermi paradox of why there are no signs of civilizations.
