to the people who says this don't matter to "regular guys"

Is this really something a regular guy working hard to eek out his existence REALLY needs to know or is it just something you physics types get all tingly in your underpants about?


Imagine you woke up naked in a field, in the middle of nowhere. You have no idea where you are, or how you got there. What do you do? First, you'd probably go into survival mode; you'd look for the basic necessities to sustain life: water, food, and shelter from the elements.
Once you had everything you needed to stay alive, and you knew that, if nothing else, you could at least remain in your current location indefinitely, you might start to wonder what in the hell happened: one minute you're bouncing around Reddit, the next you're bare-ass in the middle of nowhere.
After you come to grips with the reality of the situation, you'd probably want to try and figure out where in the hell you are. You might try and look for clues from your environment or maybe a constellation you recognize, or perhaps you decide to do a little exploring around the immediate area, to see if there's anything around that could give you some clue as to where in the hell you are.
Let's say that your efforts reveal that you're in the middle of Africa. Once you've figured out where you are, you only have two choices left: stay there and simply exist as long as you can, or attempt to get back to civilization; either option has it's own risks.
If you chose to stay where you are, then that's essentially it for you, you now know how your future will play out: you'll remain at your current location until you either die of old age, or your area becomes unable to sustain life. Either way, the game is over for you; your entire existence becomes about survival, and you're just running out the clock until, at some point in the future, you cease to exist.
Maybe you decide to try and leave a message for someone to find in the future, maybe you're content to simply fade off into oblivion, either way, your fate is sealed.
Now let's say you decided to try and get back to civilization. Since you know where you are, your logical next step is going to be to try and figure out someplace to go, and then of course, how to get there. Now you have a goal, something you're striving towards. Life ceases to be about mere survival and becomes an epic journey to get you where you want to go.
This is the timeline of humanity. We woke up with nothing, on a little rock, in the middle of nowhere. We figured out how to survive, and we struggled to come to grips with our own reality. Then we started exploring, trying to find out just exactly where we were in the Universe. Now we're faced with the same choice: exist, or move on.
You ask if it's something that a "regular guy REALLY needs to know", to me it's the most important thing he/she needs to know: that humanity chooses more than an existence of mere survival. That humanity chooses to move forward and keep exploring and expanding. To know that, even though we might never make it, at least we're making the effort. That we have hope.
The alternative is to simply run out the clock and wait to fade off into oblivion.

But if there is a multiverse, then would it not be valid to say that there have been a number of Big Bangs? Each forming its own universe, its own time and its own space?

There is a theory which says that our dreams are images of what our alternate selves are doing in the parallel and alternate universes !

For every choice we make, every decision we take there exists a parallel and alternate universe where we have taken a different decision !

A multitude of universes bending the very fabric of space and time !.

What if that other universe is independent of the big bang in our universe?
 
Well it can be independent or can't be
We just don't know yet
And we will never physically examine the universe
Even at the speed of light or nearest star is 4 light years away
We may take time dialation in consideration that at greater speeds the time slows down but still if we see a human there waving his hand and travel there at the speed of light we will feel just a second passed away but the man will be 8 years old and won't even remember the waving of his hand
Let's hope we will be able to achieve more than we've achieved in 20th century

parallel universes is one of the theoretical ways explain hierarchy problem. scientists are a perplexed about gravity not being strong enough. apparently universe can influence and interact with each other in some models of cosmology, but mostly this is enough if only gravity leaks to other universes.
if the megaverse/universe is truly independent, then there is no difference for us between theoretical and real, because we can only imagine it but never get any direct evidence for it
 
Or maybe we live in the matrix?

For me, it's enough to know that based on actual calculations more scientists openly believe that matter / energy travelled faster than the speed of light from the point of origin (big bang). If nature did it, humans can replicate it one day too, hopefully. That's the exciting bit for me.

Plus, how would an explosion look to a one dimensional or two dimensional creature? Maybe the big bang happened in more dimensions than we perceive and thus created all the parallel universes as well - in all the other dimensions, or maybe just one more dimension.

For me, just one additional dimension makes it possible to have one, or billions or trillions or countless universes more, just as the Z axis allows us to perceive a sheath of papers vs just a sheet. Whether it's one additional sheet or a trillion more stacked on top of each other, it's all possible with just one extra dimension.
 
Well yeah but big bang didn't happen at a single place
It happened everywhere in the universe
This was found out by scientists when they compared 2 images taken after years and whichever star they choose it appeared as its the center

Also 4th dimension adds the possibility of another universe
Like if we take 2 dimensional object like paper and bend it like doughnut it is infinite in 2 dimensions but finite in 3rd dimension
Similarly if we take a cube and connect all the ends so it's infinite then we get a hollow sphere where the inside of the sphere is the outside of another 3 dimensional universe and the outer side is the inner side of that universe

It's complicated but easy when you start thinking in the 4th dimension

These are some great videos explaining hypercube
Apply the same principles on the sphere and it will start to make sense
