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.

I have a theory but it is just something that I have thought to myself and
is in no way scientific or whatever.
I think that somehow matter has the property to exist or not exist, what I
call nothing is not an empty space but just something that doesn't exist
yet, somehow matter in this universe has the property to create existance,
space and time, so literally it is not expanding into something, it is just
the universe creating existance as it advances, anything outside the
universe doesn't exist.
That would explain why universe moves faster than light and Big Bang
expanded faster than light, Einstein was right that light is the fastest we
can go but once we live in an existant universe, as the universe would be
literally creating existance then it means there are no rules of speed that
it would have to follow, the rules of physics can only exist once there is
something, if the universe is creating existance it could expand at
whatever speed possible.

the narrator said if we cannot see the edge of the universe now we never
will because it is expanding. this I think is nonsense. 200 years ago we
thought man would never fly or see the bottom of the ocean let alone go
into space and explore the planets. don't be so quick to put the human race
down. the hubble telescope is a good example. when astrophotography was
young we looked at the cosmos and thought these were the best images we
would ever see. now hubble can peer into an apparently starless patch of
space an detect many new wonderful galaxies that we would never have
detected from earth. my point is just because we can't think of a way to
detect it now doesn't mean we never will. even if it does keep expanding.

the Earth is on a Star System... a star system is in a Galaxy... Galaxies
are the sources of light and which is why Universe keep expanding...
Universe has an edge... but the Edge expands with speed of light.. Time
moves "normally" inside the expanding universe... If you have successfully
defied the physics and thrusted your rocket more than the speed of light,
you'll reach the infinite space. But the space outsidr the universe is
instantaneous... which is why you'll feel that you can't reach the edge...
every time you do so, instantly the universe expands on your region...

therefore, what the universe is expanding into... is Infinite space...

Hi all,
I have a problem that could maybe be discussed in one of the new videos.
We have all heard about space expansion. The proof for that we have is the
red-shift of light coming from distant galaxies.
But my question is how is the space expanding? Is it the number of Plank
Lengths being increased or the number stays the same and the Plank Lengths
it self are increased? The second solution sounds nonsens but still leaves
an open question... because if the number of Plank Lengths is increasing
than where are they coming from?

Автор Roj H ( назад)
We're just looking at it the wrong way around. Space-time isn't expanding
into anything. A better analogy is that the 'amount' of space-time is
increasing inside the singularity of the (poorly named) Big Bang. From our
perspective, this creates more space (and duration) within which all the
material stuff can occur. It also has the effect of pushing all that stuff
away from all the other stuff (or at least seeming to) as greater
quantities of the space-time medium 'fill in the gaps'. Outside the
universe, there's nothing to expand into where space is a meaningless idea;
from that perspective, the universe is a timeless point of zero size
indistinguishable from all the other absence of location or duration.

Is there any concise sources of information that describe how in astronomy
distances are determined? I am not looking for " well you see there is red
shift and blue shift.. look at my hands wave!", but common language
explanation of the concepts involved.

It seems like those methods could be talked about a great deal more.
Especially given science is about evidence and not unsupported belief.
Would be just as useful and interesting to mention often for active
scientist as saying 'Quantum Einstein' is to laymen.

How can the universe be 91 billion light years across, but only 13 billion

I was under the impression from other videos, by tracing back the big bang
to the source point , a finite amount of matter erupted based on quantum
mechanics and how much matter can be crammed into one cubic plank space
without becoming a black hole.
Now I know they claim to have weighed the universe so does all the matter
they have "weighed" add up to this theoretical value including dark
matter?Or are they short by some astronomical amount?Also the geometry has
been determined to be flat so this must mean we are not a black hole.

Considering the universe is a bounded infinity. From the observer's
perspective, ours, the further we look away, the more we see into the
beginning of space time. Since the universe is expanding into that
direction, away from us, I suspect it is expanding, quite literally, into
it's origins-the singularity from whence it spawned. The future is, in
fact, becoming the past.

Автор AntoNeo1 ( назад)
My theory is that space time expansion is faster than light, space expanded
faster than the photon ever could, it was not bound by matter just length
and width, it could be a cube, a pyramid or a sphere in shape, but the
matter that makes galaxies could be in a sphere within the basic shape like
smoke in a room, while the room doubles and expands upon itself in each
expansion, but matter will ultimately run out, but if the universe creates
mirror expansions of it self does it mean it copies the other galaxies with
it on a quantum level, are those 20 Billion Galaxies just that a quantum
version of ours? A form of Grid cube universes of each island universe
known as a galaxy. But if we are a design then the Earth is the Universe a
memory card version of all the information.

There are things we can understand with our minds and things we cannot.

Infinity: Some things are beyond the mind, thus beyond understanding. The
mind has to realize it has limitations. All infinite and never-ending
things are beyond the mind, and the essence of everything is infinite and
never-ending. Example: we cannot comprehend that the universe goes out
forever, but we can understand that it has to. It is impossible for the
universe to stop going out. Something has to keep going out, even if it is
just empty space. This tells us infinity exists. We can understand infinity
exists without understanding infinity. Outer space is the easiest place to
see infinity, but it is actually the nature of everything in one way or
another.go to truthcontest ▲ com "Google "Truthcontest and read the

I'd imagine the universe is expanding into...void. Absolute nothingness,
the same void that surrounded the singularity just before the "big
bang"...assuming that particular theory is correct. That goes for a
universe that's either created by an intelligent designer (God) or simply
came to be on it's own.

The void/nothingness is removed from space/time, and therefore is infinite.
The universe is finite, even though it could theoretically expand forever.
Eventually, the universe as we know it will die...when all the hydrogen is
used up, and stars will no longer be born. Even then, the universe could
continue to expand into the void. Space/time might continue to exist, but
the universe will be very dark, and very cold.

That's my opinion.

"boundary is so far away that it can never affect us". wtf? wtf kind of
answer is that? Like 99.99999999999....% of the current universe is close
enough to affect us? So does that mean because it doesnt affect us like
99.999% of the current universe, we shouldn't study or question it? By that
logic we shouldnt bother with anything outside our galaxy. But we do. Out
side the next 3 galaxys next to us. But we do. Thats the point. It all
started with us venturing just 40,000 miles off our own ground, and now
were out viewing things trillions of times further than that. Why
arbitrarily stop in between where we are now and infinity. Were striving
for infinite knowledge. Worm out of this one: what was the ultra-dense
singularity of the universe sitting in before it exploded???????? Where did
the singularity come from???? All the matter in the universe now, was once
condensed into that singularity, where did that matter come from?????? I
thought matter couldnt be CREATED or destroyed?? you are following theories
and laws to explain this video, that agree with conservation of energy, yet
it is defied by the singularity. PSEUDO SCIENCE. The idea of the
singularity is pseudo science as well. It all is past 13.7 billion
lightyears. So dont talk about things beyond that many light years as fact.

What was there BEFORE the "big bang"?

Автор thimphu1 ( назад)
It can happen that Universe is not expanding at all. We believe Universe is
expanding in our 3 dimentional space, but according to the nowaday physics
Universe has 10-11 dimentions and our 3 dimentions is just a projection of
the whole number of dimentions. And this expanding could be just a changing
of 3-d projection. Let's assume we live in 1 dimentional world in a line. A
line (let's assume it's on the X scale) has infinte lenght, but it can be a
point of zero size if you look along it when Y=0. A kind of singularity.
Like that one before the Big Bang. We can't move along Y, but let's assume
the world is made this way that it is always moving along Y (like Time in
our world). Then if you move above this line along Y you will see the
length of the projection of this line will grow with increasing speed. But
the line is the same, just a projection is changing. In our world Y is
Time. We can't move in Time, but our 3-d world is moving along Time scale
with us and we see the 3-d world (actually a projection) is changing,
expanding with increasing speed.

The universe is not expanding.
If the space between galaxies is really expanding then we know what happens
to any point in that space, it will double, just in a moment. That means in
three moments all the galaxies will disappear out of the visible radius.

if something is eternal then it has no beginning and no end but the instant
we realize that there was a beginning by definition it cannot possibly be
eternal. Take for example life and death - life has a beginning and an end
but we think of death as going into eternity which does not make any sense
at all because even death has a beginning so it cannot possibly be eternal.
However looking at things in a linear fashion everything makes a little bit
of more sense. When a human is inside the womb there is a beginning there
and an end when that human leaves the womb or that world after 9 months and
enters this world - does it mean that we ever want to go back into the womb
? No, no one is interested in going back - then in this life just like in
the womb we develop and finally die or simply leave this world and enter
another without ever wanting to come back to this one - thus the dead never
returns - the human in the womb has never seen this world and when he or
she is born notice how afraid they are until placed in the mothers arms.
The same thing happens with death. We are so afraid because we have no clue
of how it is going to be. So thinking about things in a linear way helps to
understand.

Some people say that the universe is expanding and big bang is happened
because they see it by the red shift. And, they say that the saw by the red
shift, galaxies moving away each other and from us.
Well, if this is not pure lie how could they see by the so called red
shift, that the galaxies moving away from each other even if they see
galaxies moving away from us?

An expanding universe with static contents is equivalent to a static
universe with contracting contents. The latter model requires no pesky
background space or continuum, neither of which can be made intelligible,
and instead models reality essentially as proceeding via "descriptive
processing". See C.M. Langan's CTMU pdf & "Physics & Metaphysics" pdf.

Автор Shadowman1965 ( назад)
The question is a good one but can never be answered with our current
technology. Most people, even educated one still think that the Big Bang
was an explosion in "space" not an explosion of space/time. I remember
learning the steady state theory of space when I was a much younger man,
that never made any sense to me. Of course the Big Bang theory was already
around in the 70's, it had just not become well known to the public yet.
The fact of a beginning is about the only evidence of a supreme being for
me, did something will space/time into existence?? Of course, if there is
a "God" it is nothing like we imagine or even could imagine. It would be
like asking a virus what a human is like, only taken to an infinite
amount. Only one way to find out for sure, die.:)

The Universe isn't expanding into anything as there is no predefined space.
The universe is everything that will ever exist, so any talk of there being
a physical boundary is nonsensical. The only "boundary" that does exist is

If one believes in The Big Bang (and I don't mean many... I mean *THE* Big

Which means the Universe is lopsided, and continue to be.
And because Gravity rules all... everything will eventually go toward that
direction and the Universe ultimately becomes a straight line !?

there is also a 3rd possibility: imagine a balloon, its surface is not

was before. i think spacetime is a bit like it.

In my opinion and this is also a thoery, I think the universe is similar to
planets where is if you travel far enough you'll end up right where you
started. Unlike the planets the universe has the ability expand. So in
short mybe the "edge" of the universe is just another point of the universe
but constantly expanding. I like this theory because I can wrap my mind
around it lol. Also since space expands and contracts that also means
warp-drive's COULD be possible.
