What is the Universe Expanding Into?

By popular Space Fan request, I offer this video to help answer some of your questions regarding the expanding universe. Many of you consistently ask: If the universe is expanding, then what is it expanding into?

This concept is non-trivial to try and explain in a 5 minute YT video, but I do my best. I hope this helps!

Thanks to all of you space fans for watching this channel, it means a lot to me.

Our universe is expanding into a mega universe. There are more universes
inside this mega universe than there are grains of sand on all the planets
in all of the universes.

I find it interesting, and indicative of the problems inherent in human
understanding, that the two possibilities we can come up with for the
Universe (all that is, not the universe which is all that we can see) are
also unfathomable to us. We either live in an infinite universe or a finite
one. If it's infinite, we can't imagine that, period. If it's finite, it
either exists on its own in nothing - which is also unfathomable, we can't
really imagine nothing, only lack of light and energy - or within something
else, which then again falls to the same paradox.

I thought that because at the time of the big bang the universe expanded
faster than the speed of light we can't actually see the whole universe and
therefore don't know how expansive it actually is. As far as I know they
haven't located the point of singularity. Is this true?

If the Universe were to be infinite, it wouldn't have had a beginning.
Indeed, worth adding, if the Universe were infinite even for aspect of its

No true we may see beyond in the future - expending faster then light means
that light emitted at some point outside of visible universe may become

There is no reason for the universe to ever continue so is should by you
you said. You have showed its total annihilation from the Earth we live.
You claim that the universe should end because of your ignorance. Not only
end but this is the end and you sleep every night claiming that you every
night is the end. We see something great being born in its place. Born
because of this sick end of us all. A sick that will not be and always was.
Do you claim that your sickness is and always was? You herd what is and
always was and there is better to still to be written as to whats come of
it. What is and always was is what is still to come. Come because there is
something there to see it as what it has to come.

universe, and in the scale of the atom, would this stretch have anything to
do with the nuclear strong force or weak force?

An object moving trought a lower dimension might look like it increases and
decreases in size, like a sphere moving trough a 2 dimensional membrane
would. I believe the reason the universe is expanding might be because the

i don't get something and i would like for an expert to answer it
how can we tell that the universe will keep expending? how can we predict
that this expansion will continue the way it is?
is it not possible that the universe is only expending now, like an
explosion? and when the force of the explosion will stop, that expansion
will stop with it?
thank you

Автор phiddlehead ( назад)
The massive center of a galaxy, perhaps a black hole, acts a 'cosmic
drain'; we are spiraling in towards the center of our galaxy. Gravity warps
space-time; the closer to the massive gravity at the center, the more
space-time contracts. Therefore, space-time compresses as you approach the
center. In other words, we are shrinking. There is no way we can tell the
difference between us shrinking and 'the Universe' expanding. "Honey! I
shrunk the Galaxy!"

Автор garcemac ( назад)
The "universe" is not expanding, Spacetime itself is expanding faster than
the speed of light. We will never find the edges of it. If the "universe"
started with the big bang and is expanding with spacetime, then it is,
indeed, finite - and it had borders. I truly believe that there are other
universes. Everything orbits something.

we could call it anything, but the reality is our universe is expanding. It
is expanding into the vast vacume of empty space. Our universe or more
accuratley our small bubble, is one of many and probably millions of
billions of other universes or bubbles.We as inhabitants of a small blue
orb in a small pinhead size of our own universe, can only begin to
contemplate the vast expance of the reality the vastness of the reality.
There are many universes each with billionsand trillions of galaxies.

I'm sorry but its NOT expanding, the reason they think it is ? Well look at
it like this we are spinning and the galaxy is spinning and the universe is
spinning and the other universe's are spinning and when we look at it from
earth the spinning look like its Expanding! its that simple , if everything
was Expanding like they think then everything would be, our moon would get

Somehow, when I saw the question "What is the universe expanding into?", I
thought the video would attempt an answer - but it only asks the question.
What's the point? Is the question being asked in the hopes that somebody
else will answer it?

Before you can ask what the Universe is expanding into, you have to define
what the Universe is, and this video doesn't even do that. To suggest that
it expanding into something would be to suggest that it has a boundary - a
surface, but the video doesn't know - so how can it conjecture that there
is something outside of the Universe, into which it would then be

The universe is not expanding at all. The galaxies are not generally
receding from each other. Their redshifts are neither due to the doppler
effect or the "creation of new space-time". They are due to light losing
energy to the molecular hydrogen that fills interstellar space.

Mainstream science is gonna have to let go of this dumb-ass big bang theory
at some point.

What if it's not expanding but going back to the point at which it started?
Kinda like water down a drain, the closer you are to the drain the faster
you go to the drain, the farther away, the slower you move to it. What if
it's not expanding, but one side that we look at is closer (to the drain;
or the singularity), and the other side we look at is farther away, so
distance is becoming greater between us and that's why we observe a red
shift between us and them (stars)?

What if the expanding has already stopped? How would we know the difference
between expanding and shrinking, if the shrinking was in a way that I said
in the top of this comment.

I doubt that the Big Bang Theory is actually a single bang because any
galaxy is too big to conceive that I suspect that each galaxy is actually
more of an universe itself.. which I mean that each galaxy began with its
own big bang.

How do we see photons from the earliest parts of the Universe? That relies
on the premise that we are here before the photon gets here, and if the
photon started travelling billions of years ago, before the earth was even
formed, how did the matter for the earth to form from get here before that
photon did, when the matter the earth is made from came from supernova'd
stars, the matter of which came from energy, which came from the Big Bang.
All of those things would have to get here and occur before that photon
could get here, which left it's origins way before the matter we are made
of ever got here, so how is it that a photon travelling at the speed of
light got here billions of years after the matter did? I just don't follow

I think the universe and spacetime is like a flower unfolding, or new
growth appearing on a plant. In that way, plants mimic, and are
manifestations of the structure of the universe. The universe then is
probably a crystal lattice like plants are, but obeying its own laws of
growth. The question of from where does new spacetime arise, and into what
or where does it expand is the same as from where does a new petal or leaf
of a plant arise.The answer of course appears to be magical in nature.
Therein lies the seed of all creation, that initial spark of being that yet
resonates through the cosmos. The closest we can come to understanding the
laws of the universe might be the Fibonacci sequence. In that light, the
universe can be seen as a recursive, crystalline fractal. Ebbing and
flowing, undulating and growing. A wellspring of energy upon an ocean of

@Deep Astronomy .. 1.) The Universe is not expanding into anything.. Just
like there was nothing, not even time, before the Universe began to exist,
there is nothing outside the Universe for it to expand into..

2.) The expansion of the Universe is absolutely not creating new space-time
as you said in your video.. The expansion is simply stretching the already
finite amount of existing space-time.. Think about what you are saying...
When you blow up a balloon are you creating new balloon surface as it gets
bigger and bigger, or is the surface of the balloon stretching? I think the
answer to that would be immediately obvious to a group of Special Ed

The total sum of everything in our closed system came into existence at the
same time, all at once, and then expansion took it over from there..
Nothing has been newly created, or destroyed since..

The Universe is finite in the sense of matter, energy and time, but
theoretically, if you could just start traveling through the space of an
expanding Universe, the Universe would appear to be virtually infinite to
you if the rate of expansion is happening faster than you can travel.. You
could never reach the border/edge of a Universe expanding faster than you
can travel, so it would seem to you to go on and on and on, forever.. This
is if time wasn't finite.. If time wasn't finite, then the Universe could
simultaneously be finite and infinite.. Finite in the sense that there's
only so much matter and energy in the Universe, with no matter and no
energy neither being created or destroyed, while the infinite stretching of
finite space-time occurs, but again, the problem is, in time, our Universe
will cease to exist altogether, just as it began.. Like death, time is the
great equalizer, without it, empty space couldn't exist, and without space,
there would be no place for matter to exist..

Space itself is the boundary. The finite universe is a toroidal pulse wave

Автор Peter Herz ( назад)
I'll share with everyone what this video misses telling deliberately and
succinctly. The Universe like all matter and the Earth herself is shaped
like a sphere and thus the perplexing question of its shape and dimensions
similar to flatlanders before they circumnavigated the globe to make the
spherical discovery. As far as its expansion 'into' anything else that
depends if you believe in an infinite formless God who uses spheres as his
or her geometric instrument on all scales that integrate into unified
physics. Thus the big bang was a conversion of infinite self into infinite
particle bindings of energy where the Universe is expanding and decaying
into God cyclically.

When I was at school, one of my tutors said "never say never". Our cosmic
journey has, basically, barely begun - and I think we will have to do more
researching and a lot of theorising before we can say that we will never
reach the edges of our galaxy and cosmos.. One question I've wanted to ask
is , while looking at a picture of galaxies and assorted stars what exactly
fills up so much of the space between the galaxies? Are all those white
spots simply stars and their solar systems?

This was awful you could have given us theories about what the universe is
expanding into. Such as, the black hole theory, or anything really, not
just we don't know, but it is accepted that the universe is infinite so it

expanding into something, what if it is expanding in a multiverse give us
something not just well we are not sure.
