hello. actually im still at college and wouldnt understand much about these physics. So id like to ask. I once read that when you go in a straight line you will come back to your starting point. doesnt sound sane to me actually. but could it be possible that instead of moving away from each other, they eventually warp back and all of them collide together. sorry for any nonsensical rant by me, just having a curious mind
The other day I was in math class and I asked my teacher about what we were learning about. I said,"Do fractals resemble the universe constant expansion?" Everyone looked at me very strange but I could see that he was impressed by the connection i had made. Do a short on fractals please! I made a few fractal animations myself but idk what I'm doing sooo I'd like you advice on my question.
This is awkward I posted that comment on my friends youtube account thinking it was my account. However, you can check out the animations on this account:) mb

PROVE THIS WRONG: all matter and everything is constantly shrinking at the same rate except for open space making the distances between galaxies seem to move faster and faster apart when really the gap between them is getting bigger . Also tell me if this is an already established theory because I have been thinking about this for a while and honestly i'd REEEEAALY like some recognition from the scientific community, SINCE IT IS AWESOME.
Also, if all the other galaxies in the universe suddenly vanished, our world would not be any darker or lonelier than it is now. The only galaxy visible to the naked eye is M31, (and the Magellanic clouds, but only in the southern hemisphere) and that is only a tiny blur in the night sky that most people have never even seen. So cheer up.
"All galaxies are moving away from all the other galaxies." This is blatantly false since the Andromeda Galaxy is approaching the Milky Way at about 100 to 140 kilometres per second. That's the trouble with these minute physics things, they leave a lot out.
@dstdvl When you can make a video a couple of minutes long on a topic that has covered centuries of research and thousands of books, papers, etc, WITHOUT leaving anything out, please give me a call :).
I liked the idea of the vacuum energy driving the expansion of the universe. It's easier for me to understand :P Since the Further you go, the less matter and energy you see, therefore the vacuum becomes closer and closer to perfect, sucking harder and harder on you the further you go away from everything else.
In islam we know there is an end for univese but no body knows except god only,and when that time comes god will ask every single humen beings in his life , if we belived that he is the only god and did we do will in our life meaning did we do what god told us to do .
@truebeliever2011 according to your statement, "nobody knows there is an end... for the universe except god"? since we now know this fact, we must therefore all be gods.
P.S. what did god tell (us) to do -- behead all unrepentant nonbelievers?
P.P.S. end of 'humanity' in the sense that mankind is slowly degenerating and becoming absorbed with superficiality and materialism, losing our 'humanity', it will surely end, but the universe will end and be reborn over and over, likely without mankind.
@DarkAvengerXVFilms "The universe will gradually become a lonelier, darker, emptier place". If you don't find it depressing you may better slow down with antidepressants
@resoprint I don't take anti-depressants, but the idea that we will drift further away from other galxies and such is just something that i don't find depressing at all.
Or maybe the Universe is still accelerating like a bullet continues to accelerate until it reaches a certain point. Considering how massive the big bang is supposed to be, maybe it will take 20Billion years for the expansion to slow down.
The other fun tidbit is that the inner teardrop is rotating in an opposite direction from the outer Cardioid. The intersection point is the interesting zone flaw.
By the way, the teardrop in the center of the polar coordinate plot is your known universe.
By the polar plot of; R = U + cos(t) , with t = 0 to 2*Pi, and U is decreasing from 2.5 to 0.
As the variable U decreases your "universe" (the inner teardrop of an off-center one) appears to expand quicker and quicker.
In case you are wondering, your known universe (you're not the only one out there) in this particular low-quality example is rotating around the angle 0-axis. The Cardioid is a 3D object.
Actually, this universe exists as a Cardioid expressed in 4th-directional spacetime.
The universe is not expanding so much as reaching the limiting zone of the exterior of the function. Plot in polar form; r = 1+cos(t). This is your "Big Bang". This universe, when it went off the temporal rotary center shown in r = 2.5+cos(t).
Your variable is r = U + cos(t). As the variable 'U' decreases, so the universe nears collision with the inner wall of annihilation.
I don't think its expanding... I think its collapsing to a singularity. Just because we see it moving very fast in one direction doesn't necessarily mean its expanding... it could be going toward a point.
@pogowitwiz Agreed there. "The Universe" is a title for the container everything is in". And combined with this video's content (plus what the video touched on, that Einstiens explanation for gravity is not a 'pull' but rather a 'push' going on...then there would also be something to consider about whats 'outside' this container we call the Universe which should be affecting objects movement.
@insyncnet1 In other words...wouldn't there be a 'push' effect on the outerlimit objects...pushing objects back? If so, it may be not as influential as inertia & etc.to slow down the speeds outwards. Because internally the Universe's objects would have a degree of velocity already in progress then add Dark Energy further pushing objects from each other. The two combined would dominate over external Dark Energy pushing in. Does that make any sense? o heck i dunno. I luv this stuff tho. heh.
Nice video , everyone check out my channel and give me a shot (Subscribe) . First video comng soon in my channel so i will appriciate if you check the channel . Thanks
what if there are universes within universes, because the galaxies spread out so much that there are empty spaces where new universes started? I can't really phrase it but what if?
@theabridgekid I believe (though I'm not that well educated in this field) that our universe is really just how we describe the space all the stuff is in. I'm saying that "The Universe" is a title for the container everything is in, and if more stuff were put inside, then it would still be in the universe.
@theabridgekid Well that would be finominal for we could actually see how universes were created. BUT i dont think so cause for that to happen a universe would have to begin and we would instantly catch a explosion of that magnitude. AND i dont think that the space between galaxies is enough to fit and entire universe since we live in one and thats big enough to fit MILLIONS of galaxies so i dont think so.... good theory though that would be cool =/ =P
Dark energy has negative pressure, so we're not just talking about the kind of vacuum we can create in atmospheric conditions. The more the vacuum expands, the more dark energy and the more negative pressure there is, so the harder it is for gravity to pull masses together. This means that things will keep on accelerating away from each other forever, until (entwined with entropy), the universe is just a luke-warm soup of subatomic particles.
What is to say we are not all just still being pushed away by the force of the big bang and that gravity hasn't taken hold yet to pull us all back together?
@huddl3buh50 Then what energy drives the acceleration today, and will in the future? The explosion has happened, it is PAST. The acceleration is still PRESENT.
This was the first Minutephysics i found by mistake searching threw the vastness of youtube...i clicked on it cuse the pitcture looked cool....i stayed for the physics
But shouldn't it eventually stop expanding? I mean does the "empty space" add more space to it as it expands? It can't go on for an infinite amount of time, even if it is going faster by the second. Eventually it should slow down because of the fact that it's getting less crowded and possibly should shrink back in due to gravity (and maybe bounce back and forth between shrinking and expanding until it eventually settles).
Somehow, with the expansion of the Universe, more energy of space is (theoretically) appearing, causing the expansion of the Universe to speed up. Because "empty space" contains energy, and energy can't be diluted into space, more energy appears to occupy this new space and cause the Universe to expand faster and faster
@joey1257984 But doesn't that go against the "conservation of energy". I'm not too sure how Vacuum energy works, but I've always thought that you can't create (you said "appear") energy. You can only channel if from another source/form of energy. Meaning that maybe the remaining space energy is diluted or the impact of energy varies based on positions relative to other objects on a macroscopic scale....maybe I'm over thinking this a bit.
@Raptik666 Yes, what you're saying is true that energy can be neither created nor destroyed. In a closed system, this applies. But as the Universe expands, the entire system is changing. Energy cannot be diluted, and with more space coming into the Universe - from where, we don't know - more energy of space is coming with it. In fact, this is only theoretical right now, there's no real evidence that this is actually happening.
@kyleisreallycool --- We got this in our physics class... but we never got told why it is heading towards us. Also why does Andromeda have a blue shift ? :S
@kyleisreallycool what does that matter to you. And what if the Andromeda would move towards us. It will move towards us over time but that's nothing that breaks this principle the fact that everyday it's moving towars us slower is another fact though it's velocity is increasing.
@kyleisreallycool Not collide, merge. Due to the vast distances between celestial bodies, there is only a tiny possibility that anything will collide, Andromeda will simply pass through and merge with our galaxy.
@kyleisreallycool andromeda is the only blue shifted galaxy. It just happens to be on a collision course with the milky way but the space it's in is still expanding
@kyleisreallycool Yes, andromeda is an exception in that it is on a closing in on us. Mostly because, universally speaking, it is pretty close to us and gravity keeps them together. However the idea that the universe is expanding still holds because the milky way and andromeda are riding the expansion together.
@kyleisreallycool its moving faster towards us then dark energy is pushing it away. its not so much gravity as it is the fact that andromeda is just movingnreally fast
@kyleisreallycool Within the strands and clusters of our universe the force of gravity is still too strong for dark energy to counteract, so the local group is not going to rip apart anytime soon. The galaxies scientists have been looking at to infer the existence of dark energy are much much further away.
@kyleisreallycool It's because of the gravitational pull of both galaxies, it's too great to become subject to the pulling apart of the universe, however, as both are moving closer together, they are moving father apart from other celestial bodies.
@Forkontheleft10 Actually, we are moving towards the sun. In a few billion years, if for some unexplained reason the sun didn't change in any way (it's going too...) and the earth didn't break up after getting too close... we'd eventually literally spiral into it. Don't worry though... life wont be possible on earth by that time...
We're not moving away from the sun. Basically the larger the space inbetween two bodies, the greater the force of vacuum energy. But we're fairly close to the sun and the force is the little to push us on a notable level.
if we would move away from everything around us, we should go every way, meaning we would go in our own matter, so we would collapse in ourselfs. that would mean kids, you don't grow in puberty, you get smaller.
@clevelandtyler2 yeah but it says its moving away from us, which makes it sound like we're staying on the same place in the center of the universe and everything around us is moving away from us, but thats not the case is it ?
@lehmejoun it's all relative. It's moving from us if you see it from our point of view.
If you now move the point of view in let's say Alpha Centauri, We would be moving away from them.
What I don't get is : there must be a limit to this expansion, since nothing can move faster than light. Unless you consider a limited universe where both extremes would move relatively from each other with a speed slower than light speed. But we're not likely to know it cause of the Even Horizons, for now
@lehmejoun He just uses "us" as a reference becuase it's where we are. It just makes more sense to says "us" than alpha centauri or some other galaxy, but yes, everything is moving away from everything else at an ever increasing speed.
Accelerated expansion theory is based upon assumption (And in my opinion, untrue). There is no real basis for it. The only way to prove accelerated expansion is to measure the same phenomena (Type 1A supernova) in 2 different time intervals, and measure the speed at which it is traveling (Through spectroscopy). This is impossible, and as such - this theory is unproven.
Well, how do we know that dark energy expands the universe by spreading matter farther and farther apart? It could just be that it creates the illusion of universal expansion through the compression of matter.
When he said that the galaxies should be moving back towards each other after spreading due to gravity i found that hard to believe. Because the concept of Gravity is that it gets weaker and weaker as objects move away from each other, so the galaxies would have less and less pull, allowing them to move faster and faster away. And they keep moving due to the FIRST LAW of Physics, an object in motion will stay in motion until acted upon by an outside force.
@Urmomrocks159 Not considering dark energy, if you suddenly turned off gravity galaxies would continue to move away from each other at a constant velocity NOT acceleration. This is Newton's law. The presence of gravity (at least in a Newtonian sense), even if it is getting weaker, should always reduce a galaxy's velocity.
@Urmomrocks159 this only depends on the initial conditions of their speed. Under a certain speed, an object goes back. Over it, it will never go back.
Think about when you throw an apple on the moon. If you were true, it wouldn't fall back on the moon.
You are true saying gravity goes weaker and weaker, but if it weakened slow enough to cover the "need" of gravity to bring back galaxies to each other, it would work. It's all about 1/n, 1/n2 or 1/n3 comparisons in the formulas.
@StamfordLegend Not considering dark energy, if you suddenly turned off gravity galaxies would continue to move away from each other at a constant velocity NOT acceleration. This is Newton's law. The presence of gravity (at least in a Newtonian sense), even if it is getting weaker, should always reduce a galaxy's velocity.
@euducationator I know it, and I even looked it up again. The velocity does change because it is acted on by an external force (gravity). and *Physics
wait so is the universe order or chaos? because its either helping other parts of itself(nebulae creating stars) or creating suicidal intentions(black holes)
@ThePlatoon4 well ............ according to the laws of entropy, the universe used to be incredibly organized but is desending into choas, so, in a way, both.
@semiDmg This isn't logistics, its physics. Get on topic before arguing with the man with a physics major trying to make interesting videos for the smarter masses.

@TheHylianShield no because empty space has no spacial orientation
Thebrowntown1234 1 month ago
Somehow, with the expansion of the Universe, more energy of space is (theoretically) appearing, causing the expansion of the Universe to speed up. Because "empty space" contains energy, and energy can't be diluted into space, more energy appears to occupy this new space and cause the Universe to expand faster and faster
joey1257984 1 month ago
@joey1257984 But doesn't that go against the "conservation of energy". I'm not too sure how Vacuum energy works, but I've always thought that you can't create (you said "appear") energy. You can only channel if from another source/form of energy. Meaning that maybe the remaining space energy is diluted or the impact of energy varies based on positions relative to other objects on a macroscopic scale....maybe I'm over thinking this a bit.
Raptik666 1 month ago
@Raptik666 Yes, what you're saying is true that energy can be neither created nor destroyed. In a closed system, this applies. But as the Universe expands, the entire system is changing. Energy cannot be diluted, and with more space coming into the Universe - from where, we don't know - more energy of space is coming with it. In fact, this is only theoretical right now, there's no real evidence that this is actually happening.

@kyleisreallycool what does that matter to you. And what if the Andromeda would move towards us. It will move towards us over time but that's nothing that breaks this principle the fact that everyday it's moving towars us slower is another fact though it's velocity is increasing.

@kyleisreallycool Not collide, merge. Due to the vast distances between celestial bodies, there is only a tiny possibility that anything will collide, Andromeda will simply pass through and merge with our galaxy.

@kyleisreallycool They're moving away in all directions. Eventually it will collide and move further and faster away until they're all gone.
atin20 1 month ago in playlist More videos from minutephysics
@kyleisreallycool Yes, andromeda is an exception in that it is on a closing in on us. Mostly because, universally speaking, it is pretty close to us and gravity keeps them together. However the idea that the universe is expanding still holds because the milky way and andromeda are riding the expansion together.

@kyleisreallycool its moving faster towards us then dark energy is pushing it away. its not so much gravity as it is the fact that andromeda is just movingnreally fast

@kyleisreallycool Within the strands and clusters of our universe the force of gravity is still too strong for dark energy to counteract, so the local group is not going to rip apart anytime soon. The galaxies scientists have been looking at to infer the existence of dark energy are much much further away.

@kyleisreallycool It's because of the gravitational pull of both galaxies, it's too great to become subject to the pulling apart of the universe, however, as both are moving closer together, they are moving father apart from other celestial bodies.

@kyleisreallycool technically, and in galactic scale, its pretty close, close enough that gravity is sucking us together : P

So does that mean we are moving away from the sun, or is it just the galaxies moving away while everything stay put within the galaxy.

@Forkontheleft10 Actually, we are moving towards the sun. In a few billion years, if for some unexplained reason the sun didn't change in any way (it's going too...) and the earth didn't break up after getting too close... we'd eventually literally spiral into it. Don't worry though... life wont be possible on earth by that time...

We're not moving away from the sun. Basically the larger the space inbetween two bodies, the greater the force of vacuum energy. But we're fairly close to the sun and the force is the little to push us on a notable level.

if we would move away from everything around us, we should go every way, meaning we would go in our own matter, so we would collapse in ourselfs. that would mean kids, you don't grow in puberty, you get smaller.

@lehmejoun it's all relative. It's moving from us if you see it from our point of view.
If you now move the point of view in let's say Alpha Centauri, We would be moving away from them.
What I don't get is : there must be a limit to this expansion, since nothing can move faster than light. Unless you consider a limited universe where both extremes would move relatively from each other with a speed slower than light speed. But we're not likely to know it cause of the Even Horizons, for now

Accelerated expansion theory is based upon assumption (And in my opinion, untrue). There is no real basis for it. The only way to prove accelerated expansion is to measure the same phenomena (Type 1A supernova) in 2 different time intervals, and measure the speed at which it is traveling (Through spectroscopy). This is impossible, and as such - this theory is unproven.

Well, how do we know that dark energy expands the universe by spreading matter farther and farther apart? It could just be that it creates the illusion of universal expansion through the compression of matter.

Dreakie92 2 months ago
When he said that the galaxies should be moving back towards each other after spreading due to gravity i found that hard to believe. Because the concept of Gravity is that it gets weaker and weaker as objects move away from each other, so the galaxies would have less and less pull, allowing them to move faster and faster away. And they keep moving due to the FIRST LAW of Physics, an object in motion will stay in motion until acted upon by an outside force.
Urmomrocks159 2 months ago
@Urmomrocks159 Not considering dark energy, if you suddenly turned off gravity galaxies would continue to move away from each other at a constant velocity NOT acceleration. This is Newton's law. The presence of gravity (at least in a Newtonian sense), even if it is getting weaker, should always reduce a galaxy's velocity.
hwlin076 2 months ago
@Urmomrocks159 this only depends on the initial conditions of their speed. Under a certain speed, an object goes back. Over it, it will never go back.
Think about when you throw an apple on the moon. If you were true, it wouldn't fall back on the moon.
You are true saying gravity goes weaker and weaker, but if it weakened slow enough to cover the "need" of gravity to bring back galaxies to each other, it would work. It's all about 1/n, 1/n2 or 1/n3 comparisons in the formulas.

Question: Aren't they accelerating faster because the force of gravity attracting them to each other is getting smaller as they grow farther apart?
