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.

So the universe is expanding bug only in the sense of creating more
distance between objects? Or a new things being created in that expansion?

"The big bang" describes A piercing "Singularity" Everything "Matter". With
an expansion rate greater than the speed of light. What is this Singularity
expanding into? What is this " Void"? Did this "Big Bang" cause a bow
shock? I feel a headache coming on.

I propose sending space probes at various far off distances so they can
relay any images or radio signals to each other and back to Earth. I will
call the project "Leapfrog" and it may help us understand how vast the
universe is. Please donate all your money into my GoFundMe account so I
can start the project immediately after my Vegas vacation.

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
that...

... There were no Colors billion years ago. (Black, White , Gray, yellow..
etc)... No objects like Dust, rock... etc... And --> "NOTHING" did not
exist Billion years agooooo , before big bang even "NOTHING" did NOT exist.
No sounds,light , BLACK. Etc. .. 0_o... so in terms of bible.. Who created
God? and Who created God's creator.. so on and so for...... 0_o .... How

Great question... but NO ANSWER IN THIS VIDEO. DUMB...

Автор Joshua Bristol ( назад)
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
magic.

@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
students..

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
expanding in an infinite/eternal hyperspace. You can read about this in
REALITY by Un-Maa Saa.

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
really isn't expanding, but what if it isn't infinite, what if it is
expanding into something, what if it is expanding in a multiverse give us
something not just well we are not sure.

I am no cosmologist or physicist, so will someone please explain the
following seeming paradox to me? If the universe was created in the big
bang, and if it IS, and always has been expanding, then working backwards
in time, didn't there have to be SOME time when the universe was NOT
infinite? It surely wasn't infinite before it was even created, and
assuming the process of space-time expansion started at its very inception,
then wouldn't it seem that it has to have had limits as it grew/grows? Or
is it possible that a "Big Bang" that spewed MATTER out at some noninfinite
rate nevertheless accompanied a creation of space-time that was itself
INSTANTANEOUSLY infinite? My head hurts!

the Universe is a crystal snow globe and the flakes are the galaxies. but
unlike a snow globe there is no glass "boundary" when the flakes end so
does the Universe a cluster of ice crystals freely within a gravitational
"Sphere" beyond that is beyond the observable therefore laws of physics
don't exist or are different. dimension 0 is not a 3d "Space between
Universes" but nothing at all. but its there none the less. other Universe
lay on this 0 some over lap what is unobservanable to anything of
intelligence anywhere in Our Universe, and if we go to these fringes we
will not be perceiving it in 3d space, non-sense? not really.

100 billion galaxies.... 100/200 billion stars in each galaxy.... and
people still think we're alone?! It's a very well done bit of film this,
but just think, how vast this universe is, it's beyond our comprehension. I
simply don't think our minds can comprehend what lies beyond creation, is
it absolute nothingness? If so, what is it made of? Can we comprehend that
something is made of nothing? Is it made of a material that is as of yet
beyond our imagination? is it sub-atomic matter in a chaotic state?

Is the universe just a carrier? Did the big bang in fact not create the
universe itself, but just the stars and galaxies within it? is the space in
which these creations the sheer infinity we get taught it is as children?
If it is truly infinite, can our system of physics even acknowledge it as
such?

If "the space-time between all 100 billion galaxies in the Universe is
increasing", then the space-time WITHIN all 100 billion galaxies MUST also
be increasing, a convenient truth left out in cosmology and the Standard
Model. The "space-time-is-increasing-between-galaxies" excuse is
selectively and erroneously used to explain why the Universe is 95 billion
light years wide but only 13.5 billion years old. Impossible!!! If
space-time is increasing between galaxies, space-time MUST also be
increasing within every quark, electron, proton, photon, magnetic field,
electric field, etc.. Think about it. And you might want to question the
manufactured entity "space-time" as well. Impossible!!!

"Adding more fabric to infinity doesn't make more infinity." False. Not all
infinite quantities are the same. One reason "infinity" isn't a number. How
many integers end in 3? There's an infinite number. How many many integers
are there? Ten times as many. Still an infinite number.

If, as stated here, that whatever direction we look there are aproximately
the same number of Galaxies, then does that mean we are at the centre of
this universe?
If we are not at the centre, then if we looked away from where the centre
is, we would see less galaxies than if we looked toward the centre.
This assumption is based on being able to see 50% of the universe on the
other side of the centre, plus whatever percentage of galaxies there are
between us the the centre.

i don't get one thing... if you claim that we were able to see photons that
were travelling since the universe was a few millions of years old then
that means the universe is expanding from something, from a singularity
point - thus the big bang, right?
now the kicker... how can you claim that the universe is in fact infinite
since it started from something, from a physical, mesurable size? I get the
fact that time and space are being added continuously but i just can't wrap
my head around the fact that the universe is in fact ... infinite. An
infinite universe has no edges to expand into... as you mentioned

it ant expanding into anything. it is easy to prove that no light ever goes
in a straight line. Beside there is nothing it can expand into expect
itself because Universe means everything, physicists would have to redefine
Universe to mean less than half of everything since if it was expanding
into something, that something would have to be bigger than it.


The idea that you can change the passage of time is also the thought of a
real ignorant mind, since time is a measure of how far mass has moved,
changing the passage of time means you have just displace all matter in the
entire universe, an act that even god would have trouble performing.

The Universe isn't expanding into anything.
The Universe is expanding into itself.

It's hard to describe visually... Imagine a two points in an infinite void.
Say we call the distance between them 1. Say we make a ruler that touches
both points and it is exactly '1' in length. Now over time the distance
begins to grow...

1.1
1.2
1.5
2
5
10
100
1000
etc....

But we notice the ruler is still touching both vertices. The ruler hasn't
'grown' or changing in shape or size... rather, the quantity of the
distance between the points has grown.

The ruler always stays the same length, but the number of units on the
ruler increase over time. The universe isn't "expanding". The quantity of
distance is just growing. What was once 1 length is now 1.1 length. It
isn't expanding into anything. It is simply growing in distance within
itself, never changing it's shape.
