How do you define “you” if not for your distinct body, your distinct conscious experience?

Do you experience any of these copies? No. Then even assuming they exist they are not you, only copies. Similar yes, but distinct in every way that matters.

If you disagree you have to define clearly what you mean by “you”.

SpaceX has more experience than anyone else in lighting dozens of rocket engines at once. They've never had a Falcon Heavy failure in 5 years of operation.

It's not the number of engines that's the concern, it's the sheer power. This is the most powerful rocket ever made. It produces as much thrust as two Saturn Vs. The danger here is that something on the ground gets damaged by the sheer magnitude of this thing. And failure here is very possible.

You have to give a reason though. Just saying so doesn't make it true. You can call a copy of you a copy, but that's just semantics, you could just as easily be described as the copy. I mean, unless you're alluding to the idea of a 'soul' being intrinsically unique or something like that. In which case, it's no longer a scientific argument.

But it doesn't mean they do exist either, if they were guaranteed to exist, then the infinities would be equal. If one infinity is infinitely larger than another, then you cannot say that the smaller infinity could contain the larger one. What I'm suggesting is that the infinite universe could be a version of this 'smaller' infinity. While the variations within each 'universe' could be considered the larger infinity. So, it's possible that the infinite universe, is not infinite enough to contain even every variation within a single universe, much less infinite copies of it.

I mean, apparently not?

Think about it... all the shit that was gonna hit the Earth... Kinda already has.

More profoundly...

Most of the shit that was about to hit the Earth, got pulled into the moon. Look at all them craters.

So what's left? A bunch of shit. But a bunch of shit that isn't gonna hit either of us. It's almost like delayed gratification, if you think about it.

The Earth/Moon busted eachother up. Then they both got busted up for millions of years.... Untill eventually there was nothing left...

And here we are.

The calm result of a chaotic evolution of astrological impacts.

It's kinda beautiful, if you think about it.

The difference in cardinality of infinities is certainly true, but also doesn’t change the fact that they are still infinities.

Take the example you brought up.

For ever single integer, there are an infinite amount of numbers between it and the previous integer. If you’re talking about traversing the numbers 0->1 in finite time, then of course you can find that you’ll never get to 1. However we aren’t talking about traversing universes in a finite amount of time. We’re talking about existence. The fact that I cannot traverse the numbers between 0->1 doesn’t prove the non existence of the number 2.

Thus, even if the types of infinities at play here mismatch, it doesn’t mean that elements within those infinities don’t exist. They’re infinite.

I think your question is quite broad and is a combination of answers:

  1. It takes a lot of effort to become a moon! Many likely formed from catastrophic planetary events that took place over billions of years. Some likely got caught in the gravitational pull of a planet eventually end up crashing into it. The moons we see now have attained relatively stable orbits, allowing them to survive.
  2. Moons being much smaller than planets like Jupiter, resulted in them being discovered much later in human history. As you can see, new ones are still being discovered! These are new things to study! Exciting!
  3. Our own moon is much larger compared to our own planet, and played a major role in how life developed over time. As mentioned, its own gravitational pull has influenced the earth enough to moderate its own orbit/spin/wobble. Its gravitational forces generate tides and help power circadian development of all life on earth! Evolution on earth is generally powered by the ebbs and flows of changes caused by the moon , spin/orbit of the earth, and gravity (among other things).

5 minutes, simultaneous, an infinity in the past or the future. If our copy is infinitely far away, I think trying to come up with some sort of common reference frame is futile. Maybe it's more helpful to think of ourselves as 4d objects, if the 4d version of ourselves exists somewhere else, I'm not sure you could really ever say for sure whether they existed 'simultaneously' or not. As we already know that even within our own universe, time is relative.
