When it comes to time and space, it is easy
to become mind boggled.

Down here on planet earth, we are much less
than a tiny pinprick of our observable universe,

Adverbs of manner

and again, that is simply what we can see.

Many contemporary scientists speculate that
actually, our observable universe isn't

the entire picture, they believe our universe
is part of a multiverse.

Hello and welcome back to Life's Biggest
Questions, the channel that loves a good what

if ! I am your host Rebecca Felgate and today
I am asking What if the Multiverse was real?

Before we get into the video I want to hear
what you think?

Do you believe there are parallel universes
out there?

Let me know in the comments section down below!

Also while you are down there please do leave
a thumbs up on this video and share it with

a friend….also do stick around until the
end of the video where I will be reading comments

The late great Stephen Hawking's final research
paper was on the Multiverse.

The multiverse is actually a name that pops
up in a number of different strands of theories

One theory, shared by many physicists is that
when the big bang happened, our universe wasn't

the only one created, which makes up part
of the bubble theory.

Others have considered multiverses when it
comes to matter and antimatter.

Over the last few decades, Scientists have
observed a whole bunch of Dark Matter hanging

Dark matter, so to speak, are dark spots that
seem to make up 26.8 percent of our universe.

No one knows what it consists of and no one
has seen it, because it doesn't interact

with the matter scientists know about – visible
matter, that makes up around 4.9 percent of

Some cosmologists think that the dark matter
could be the sign of another inverse universe,

existing side by side to ours, but unseen.

My favourite multiverse theory is the theory
of multiple outcomes.

This one can be summized in Schrödinger's
cat paradox, or by considering the simple

Electrons can spin clockwise and anti clockwise,
but quantum mechanics says that they can spin

both clockwise and counter clockwise at the
same time…which…means there are two things

happening at the same time, which is hard
for us to get our heads around.

This creates a paradox as we have never seen
things spinning two ways at the same time,

But does that mean the other outcome didn't
happen.

This is the crux of the “quantum measurement
paradox”.

The answer here, could be the multiverse – with
each possible outcome for every possible decision

creating a new strand of reality… kind of
like tree branches…if you catch my drift.

So, if multiverses in this respect were real
it would mean that everything that could ever

have happened from the start of time to now
has happened in an infinite number of realities.

If we start small, this is easy enough to
understand.

This morning I woke up at 6am, I wrote my
blog, I sent an email, I had a shower, I put

make up on, I had breakfast, I slipped on
ice so I was late for work… there are already

a massive number of universes that would exist
where just the smallest factors were changed,

I didn't slip on ice so I wasn't late
for work so instead something else happened.

On a bigger scale, there could be a universe
where I didn't move to Canada, didn't

break up with that one ex… in another universe
my parents didn't meet so I don't exist.

If multiverses are real, there are many many
versions of you that could exist side by side

– one where you need glasses, one where
you don't….

some universes may be similar but some may
be different….

There would be a universe where World War
2 never ended or the Cold War did end in mutually

These are all reasonably basic concepts to
grasp… she says whilst discussing everything

that could ever possibly have been true to
be true… but the concept gets much deeper

when we consider all of the possible outcomes
created from the beginning of time, which,

so far as we can track, was 13.7 billion years
ago.

Planet earth was formed 4.5 billion years
ago and orbits our sun.

We have the perfect conditions on earth for
life, but if the multiverse theory is true,

there are infinite other universes out there
that that didn't happen, there will be universes

where time runs backwards, where gravity doesn't
exist… all of the constants within our own

provable physics wouldn't be the same…which
is mind boggling.

A few more things to mess with your brain
before we are done.

Again, so far as we can observe… the universe
keeps on expanding.

This means that, with every expansion, more
possible outcomes would take place…using

the earths population as a case study – if
every outcome from every action exists in

a multiverse…well…does that mean the multiverse
is speeding up and getting bigger?

The human population has nearly doubled in
my life time, with each individual creating

Do we really need to just accept the notion
of infinity, but know that we can only live

Many scientists theorize that the multiverses
exist but there is no way, considering our

universes rules of space time, that we can
ever get there… that is, unless, the multiverses

I want to talk about our friends the electrons
again before we go.

As well as having the ability to spin forwards
and back, electrons show Quantum indeterminism

– basically to keep this simple, if you
fire an electron through a double slit you

would expect it to go through one slit or
the other, choosing an outcome, however scientists

have observed electrons acting like waves,
passing through both slits simultaneously

It is complicated, but this could be a hint
towards proving the theory that multiple outcomes

create multiple universes…and actually they
are unknowingly influencing each other.

Would this mean that phenomenon like the Mandela
effect – an effect where large numbers of

people remember slightly different variations
of historical events, are actually interactions

of multiverses, rather than tin hat theories.

Ultimately, if the multiverse did exist, unless
we can access it, it isn't worth losing

At the moment, we can't prove Multiverse…
but if we could, it could be both a comfort

So thanks for sticking with me through that
brain work out – do you believe in the multiverse?

Let me know in the comments section down below.
