You may have heard of black holes, but have
you heard of white holes?
White holes are the unicorns, the fairies,
the elves of the galactic landscape – areas
of piercing light and erupting matter – possible
universe creators.
Hello and welcome back to Life’s Biggest
Questions – the channel that loves to talk
about all things from space, science, history
to popculture and fiction….
Why ? Because curiosity swells beyond one
topic and questions are a beautiful thing,
I am your host Rebecca Felgate and today we
are talking about the wider universe as we
ask Are White Holes Real!
Before we get into the many holes and paradoxes
of space – I want to ask you guys whether
or not your find space as a concept scary?
I feel fear is sometimes just a response to
the unknown.
While you are down there leaving a comment,
why don’t you hit that thumbs up button
and share this video with a friend.
White holes are a theoretical mathematical
concept – and a complicated one at that.
They are the opposite equation to black holes,
which we know to exist.
While we have observed black holes, their
potential counterpoints have yet to be proven
and remain somewhat fabled.
From what we know of the laws of physics,
the universe works in balance.
So, does that mean that even without observing
them, we can assume they exist?
If one were to prove the existence of hell,
would they be enough to confirm heaven?
Okay, that might have been a dubious example,
but anyways….Before we understand what white
holes are, let’s see what exactly black
holes do.
Black holes are points in space with sooooo
much gravity that all matter is sucked in
and cant escape.
Light, the fastest observable thing in the
universe, isn’t fast enough to escape the
clutches of a black hole.
We cant actually see these black holes, but
we can see the areas where light dies around
it and can no longer escape.
Black holes form when HUGE stars collapse
on themselves.
In order for something to become a black hole,
it must be small and dense – so dense that
it starts sucking in all other matter around
it.
We don’t know a lot about black holes but
it is predicted that inside the hole all directions
lead to a funnel where particles are torn
up and stretched down to a very hot dense
point of singularity.
What happens beyond that singularity, though….
We just don’t know… but one of those theories
is a white hole.
So, much as a black hole draws in all matter
to a single hot dense point – white holes
are theorised to spew matter outwards….so
really not like holes at all and more like
bursts.
Which brings us to Gamma Ray Bursts.
Gamma ray bursts are the most powerful electromagnetic
events in our universe and we do not yet quite
know what causes them.
These bursts can vary in duration, most are
seconds long but in 2010 Nasa’s Swift Spacecraft
observed one that last 28 minutes.
In 2015, it was announced that the Swift space
craft has detected its 1000th Gamma Ray Burst
– while that sounds like a lot – they’re
actually pretty rare and come from very far
off galaxies.
When observed, it seems the Gama Ray Bursts
are jets of light.
Are these white holes?
If so…where did they come from and what
do they mean?
We know that black holes vary in size – there
are stellar mass black holes, which are much
smaller roaming holes which come from the
implosion of suns much denser than ours.
There are also Super massive black holes,
which are millions of times bigger – like
the one at the centre of our galaxy.
We have given this a name - Sagittarius A
– and while it is a big black hole, there
likely is bigger.
The reason I bring this up is, as we know,
gamma ray bursts vary in size and intensity.
Could this be in correlation with varying
sizes of black holes?
Let’s circle back to Gamma Ray bursts and
draw a link between another big mystery in
our universe – The Big Bang.
The Big Bang is a very credible theory on
how our universe may have started and formed.
Many describe the event as a very hot dense
outward explosion that cooled and expanded
to form what we know today.
Lending evidence to this theory is the observance
of cosmic background radiation, that seems
to play well into the predicted timeline of
events.
Was the big bang a huge gamma ray burts?
Was the big bang the result of a huge white
hole, than came from the end of a huge black
hole?
I guess this is where science meets fiction,
or at least fantastical prediction.
Some scientific theorists, including the late
great professor Stephen Hawkin, predicted
that black holes are folds in time space that
create portals to other universes.
Perhaps white holes are just the outward end
of black holes, playing into the multiverse
theory…or perhaps they are the recycled
matter that creates a new universe.
It is all pretty mind boggling and fantastical.
Unfortunately, despite speculation regarding
gamma ray bursts, we have never affirmatively
observed a white hole, or know enough about
black holes to confirm or deny the existence
of white holes.
I wouldn’t give up hope, though.
Einstein predicted black holes but his theory
wasn’t proven for a long time.
Just because we can’t prove white holes
exist right now, doesn’t mean we wont.
The first law of thermodynamics says that
energy can’t be created or destroyed…so
while we know that black holes seem to suck
in energy….if what we know to be true is
correct – then we know that it isn’t gone.
When we find out what happens to it, we may
have our next big clue as to the existence
of white holes…and beyond!
So that is our answer there for you ! What
do you think?
Do you think there are white holes out there?
Let me know in the comments section down below!
Also let me know if you are scare of space
– would you go?
I really would.
