Without a doubt, the universe is quite large.
There are trillions of stars out there, and more galaxies than we can conceive.
Space is so infinitely huge that our brains literally cannot process just how big it really is.
I mean that unironically- the human brain hasn't evolved to be able to properly envision numbers that big.
That's why when we see numbers like 1,000,000 and 10,000,000, we can recognize that one is bigger than the other, but it's hard to realize the complete scale of the larger number's value.
That's all semantics though. Let's get back to the real question:
How can we make the universe seem even more mind blowingly massive?
Let's consider the multiverse.
The multiverse, while not proven to be true by any means, is the theory of multiple universes.
Each with their own sets of natural laws and star systems exc.
But what does that mean exactly?
The natural laws in our universe dictate things like gravity and its properties. Geniuses like Einstein, Neuton, and Hawking have all done extensive research on just how it works.
Gravity is the force that helps create everything, from stars to black holes. It's even been shown to bend space time.
That means, that if you manage to go a certain speed, or stand near an object massive enough, time bends- and depending on your proximity, time will move faster or slower.
If you ask me, that's completely insane. But let's get back to multiverses.
In a multiverse, gravity might act in entirely different ways.
It operates the way it does here because of all sorts of constants and natural laws, but those same safeguards might not exist outside of our own universe.
What if, in some other part of the multiverse, gravity makes planets look like donuts instead of spheres? In this universe, that's ridiculous. But out there? Perhaps it's possible.
Completely plausible. It's not just gravity though. What about time?
Time and space are both bendable here, but somewhere else? Maybe they're even more flexible.
In our universe, traveling to the past just isn't something we can do. But unbelievably enough, you can travel to the future.
The secret? Speed. If you move around the earth fast enough, time will slow down. 100 years on earth could be 1 week to you if you move close enough to the speed of light.
That level of technology doesn't exist yet, but who knows what the future holds.
Traveling to the past is still impossible, however. Though time can be stretched, it doesn't move backwards.
Consider another universe, however.
Maybe there, it's the past that's reachable, while the future remains inconceivable to enter.
It's a weird thought, isn't it? It doesn't feel right.
But multiverses are even more fun than that.
If there's truly an infinite number of them, that means that there's a universe out there right now exactly the same as our own, but everyone has the feet of a chicken.
There's a universe out there where the color blue doesn't even exist!
Infinity is endless, so that means that it is perfectly within the realm of possibility for there to be a universe where Superman has a handlebar mustache and all he eats are clam shells.
That all sounds like absolute garbage doesn't it?
I use these absurd examples to showcase how bizarre the idea of a multiverse is, because thinking about the possibilities is actually quite fun.
Ever sense I was little, I've imagined a world exactly the opposite of our own. Everyone walks on their hands, and when called on for a question in class, they put their hand down rater than up.
Cars floated, boats drove, and planes made excellent pseudo-submarines.
When I came up with this idea, not much came out of it, but now that I think about it- there's a universe out there that fits all those criteria.
But we can increase the scope of the multiverse even more. There are more subtle ways to showcase an alternative reality.
Instead of changes to your life, what if in another universe, everything is exactly the same, but happening merely a second after the same events unfold here right now?
Now picture a universe with the same criteria as the last example but it's happening 0.5 seconds after our own reality. .
See where I'm going with this?
In math, there exists the concept of an asymptote. Basically, it's an imaginary zone that can't ever be graphed, and the line being formed, while nearing it, will never reach that point.
Down to the micro level that line still won't cross. Now granted- once you reach calculus there are exceptions- but as a general concept, there is no crossing that zone!
Time could work similarly to asymptotes in multiverses like our own, where people who are exactly us just happen to live a moment out of our time.
If the theory is correct, then there's a universe out there where you're reading the very next slide right now, but the you from here hasn't quite reached that slide yet.
Is that a bit confusing? I hope so, I wouldn't want to be the only one scratching my head.
To conclude: space is big. Space is a bit scary. The multiverse is more so on all accounts.
The multiverse is complicated and weird, and for now, I am simply trying to get you- the reader-
To consider the multiverse.
