Makes no sense at all.Only distant space is supposedly expanding so exactly where is the dividing line and by definition it tears itself apart at that point. Also all the red shifted light is just an echo of less than light speed expansion.From that point the universe will be black and lightless because the emitter of the light is moving away faster than its light can leave it.

This is a great explanation of how the Universe/Universes and the space they are in is expanding, I recently watched a video of how quantum computers work, however, It's in It's infancy, some day they may help us understand more about the Cosmos, Thank you Ardit and Russ, and of course the entire crew that make this channel so great. 👍 🇺🇸
Yeah I asked myself that question as well. I did find ‘something’ “The universe’s expansion is a fascinating and complex topic. Unlike expanding into a pre-existing space, the universe is actually expanding ‘into itself.’ This means that space itself is stretching. According to Einstein’s theory of general relativity, space can expand, contract, and bend. So, when we say the universe is expanding, we mean that the fabric of space is stretching, making the distances between galaxies increase. It’s not expanding into anything outside of it; instead, the expansion is of space itself. There’s no ‘outside the universe’ that we know of, so the concept of space outside the universe doesn’t apply in our current understanding of cosmology.” Annnnd my mind is bending and stretching as well 😅
Ok , then please please someone make a explanation on what "space" is , getting tired of hearing about how it expands , contracts , curls in on itself thats all fine , but what the hell is it ?
Space is a void in between. Outerspace is space and as far as we go, basically it is nothing, but not like the nothing that existed outside the envelope of the big bang, or before the universe exploded into being, about 15. Billion years ago.. The space in a black hole is more like the space outside our universe, or before the big bang, and gives us clues therefore, to what caused the big bang. think of a black hole like raw parts of a pizza thats been cooked. If we measure those raw places with a thermometer, we might get an idea what the pizza was like before it got cooked. Space is varying degrees of cold to absolute zero, and it is in a vacuum. I look at it like this. when a piece of glass gets cold it shrinks, and expands in heat. Since the governing laws exist, then in a vast space of emptiness, very heavy gravity forms. pockets get so dense, they explode like nuclear warheads, giving off massive radiation, which in turn becomes a universe. The governing laws of physics coupled with research, provide scientists clues to how the universe began from nothing of space. The theories have changed some in my lifetime.. we used to use solid state theory for the universe, meaning it essentially always existed.. it was Stephen hawking probably who popularized, but did not invent, big bang theory over solid state theory, in the 1960s when he wrote a lengthy open essay to the scientific community..the former theory had nothing to with Einstein, who rejected quantum theory for his own special relativity. Recent discoveries have put big bang theory back slightly, and researchers are for now using a mixture of principles from both solidl state and big bang for theory. The many laws and studies regarding these branch off into several theories. in Einstein, a very prominent physicist who invented shared field theory, special relativity, created a term called "space time". In this he speculated both time and space move in a constant, but travel in waves.
It's like a whole new entity that no one explains. The matrix that matter and everything sits on. It can expand, curve under mass etc. I think it should be studied more
Whoever has that answer will win a Nobel prize. What Space is, is not exactly known. Mass just exists in it. Understanding, and manipulating Space, just might be the key to make a functioning wormhole. The logistics of that would make you be able to go faster than light too, because a wormhole's "tunnel" is made outside of Space as well.
Still don't get it. What's the difference between space expanding and two objects moving away from each other? If drive away from my house, aren't I also expanding the space between me and the house? My momentum was initiated by the car's engine. The galaxies' momentum was initiated by the big bang. So that means the big bang launched these outer galaxies at a speed faster than light.
So basically when space expands its not going at a speed its the space itself growing and creating distance while two objects are moving away from each other they are going at a speed. Space expansion does not have a speed the universe expands at a rate not a speed thus even though the expansion is faster then light its not breaking the laws of physics because its not going at a speed its just growing distance between two objects so fast that even light cant catch up but that does not change the fact that in a vaccum nothing can go faster then light its the limit of speed itself
It is said that expansion in between galaxies is ocurring with a very high speed ---- but how the heck space inbetween galaxies can be more than speed of light. If expansion of space in between galaxies is occurring so rapidly , how we can even see the galaxies?
The light from there took billions of years to come here. Those billions of years ago the distance was smaller and the velocity not so high. Same thing as the thing that the universe is about 14 billion years old but about 92 billion light years in visible diameter.
The space is expanding faster than the speed of light but the individual objects are not exceeding the speed of light speed limit. An important distinction.
I’m sure space has areas more dense than others which could speed up or slow down light. And also light is only as fast as it is shoot away from the suns.
In an exponentially expanding space-time universe faster than light expansion relative to the inverse exponential would still be the same as the local speed of light, due to relativity. Because time may speed up relative to a lower space-time-gravity density, relative to the space-time density of the time of the post inflationary big bang, when there would have been a high space-time gravitational density, and therefore time and light would have been slower.
I'm not sure if there's theories like this out there. But combining the gist of relativity and the notion to think outside the box(outside the universe). We see an explosion as something that goes from 1 point going outwards. Where the force is generated from the inside. And many assume the big bang does the same. What if instead of the force going outwards, there's an outward force pulling our universe appart or rather it's a matter of perspective like space+time and electro+magnetism. This could explain the rate of expansion of our universe. Similar to when you pull appart sticky substance when dense packed together its easy to pull, but once it becomes tensile you'll feel resistance. Keep going and the substance breaks apartcreating a web like structure with empty pockets, similar when you look at the pattern of galaxy clusters. Pulled appart it becomes easier and easier to pull even further appart. Ofcourse this metaphore is 4 dimensional, but the pulling force of our universe is outside our dimensions. This force might well be the dark energy we're looking for. And this could also explain dark matter something that doesn't fully interact with normal matter but it does affect the dimensions of spacetime. To me this seems like a very plausible explanation to what we know so far about our universe. Which means that we should start looking outside our universe to find the answers we're looking for.
The observable universe which is the universe we know, is not the part that's moving faster than light from us. It's the distant universe, the universe we will never be able to see.
@@CosmoknowledgeThat part is confusing because from their perspective (the distant galaxies) wouldn’t we appear to be moving away from them faster than the speed of light?
Heat singularities are the cosmic speed limit in resistance. Dark energy is expelled force of heat energy singularities as waves from decaying stars. Light is only present in resistance to mass. Heat imagining. Sparks of electrons or lights as renewable singularities energy in chain reactions until resistance is overcome by open space itself. Heat waves distort imagining in some cases. Dark energy is singularities outside of entanglement of mass as heat waves of decay from stars as singularities of thermaldynamics singularities passing through space and mass as renewable energy exchanging singularities in chain reactions until resistance is overcome by open space. Heat waves are expelled by stars decaying atmospheres as singularities of heat. Electricity is rapid heat loss as current. Theoretically factual probability that works with quantum physics.
So the fabric of spacetime can move faster than the speed of light? Because even spacetime is a reality and must represent some deeper physics at Planck levels. So the "quantum foam" can move faster than the speed of light? How come it has no mass?
I've heard the universe could be or is estimated to be at least 512 times bigger than our observable horizon, but how does the math of of expansion in reverse prove this? I mean, what would be in one spot (plank scale length) 13.78 billion ya, what we observe? 512 times what we observe? Or our little slice of infinity shrunk to max density...but then if infinity was shrunk to max density, it would still be... Big? Ugh my head hurts thinking of infinity shrunk everywhere and we just see our part
"512 times what we observe"? We are now observing some of the first galaxies to form after the 'big bang' whatever that is/was. It has taken their light a long time to reach us, but we are seeing that far. Beyond them there is only a particle soup.
Very good. These cosmic scales and velocities are ridiculous. Considering the smallest possible size of the universe, with the minimum figure of uniform expansion compounded over a diameter of 7 trillion light-years, the rate of recession of one end relative to the other would be around 480 times the speed of light. From a perspective of that hypothetical reference point even light is far surpassing its own speed.
No matter how many different illustrations are out forward, I can’t grasp the concept that nothingness beyond our universe is nothing. That area (fourth dimension, if I’m understanding it correctly) is indeed something. Even if there’s nothing there, there’s still a there? Correct? By virtue of us discussing what’s beyond space, makes a noun of it, does it not? Therefore, I’m left wondering I’ve we’ve willed the entire thing, simply on observable perception. I’m clearly ignorant to this stuff, but damned if it’s not mind boggling.
If the redshift of farther cosmic objects is greater than the redshift of closer objects - wouldn't that mean that the rate of the expansion of universe in DECELERATING - since that light began its jorney to us long before the light of the objects closer to us?
Let's be honest with ourselves we don't know what the physical laws of the universe is all we have are guesses and that's it.If we are going to learn anything about the universe we need to acknowledge what we have gotten wrong and stop trying to convince everyone that we are right when we are wrong.
Calculations are based on the idea that light has a constant speed, and always has been the same. Is it possible that the speed of light has decreased over the history of the universe? Is it possible that at the time of the Big Bang light was moving at a much greater speed?
Some physicists argue that the speed of light might've been different at the time of the big bang, however highly unlikely. The constancy of the speed of light over time and space is a cornerstone of both Albert Einstein's theory of relativity and the Standard Model of particle physics. Therefore, while it's theoretically interesting to consider variations in fundamental constants like the speed of light, such ideas remain in the realm of speculative physics
How can you claim that some galaxies are receding from us so fast that we we never see them, if we are now looking at some of the first galaxies to form?
If I understood it correctly, we are able to see the light emitted from those initial galaxies, which is the distant past. However, because of the expansion of space, we will never be able to see those galaxies as they are now because the light emitted from them will never reach us. Maybe this isn’t right but what I understood to be the explanation 🤔.
@@stbaz Yes, that is what he is saying, and that soundbite is currently very common. But if the universe is 92 billion light years across, the furthest they can be now is 46 billion light years so we will (if we're still here) observe them as they are now sometime well before the year 46 billion AD. That's an awfully long time, but it's an infinity away from "never". I find that a major problem in discussing topics like this one is that we do not use a universal definition of "now".
And if there’s nothing faster then the speed of light. Then you can’t say that the universe is expanding faster then the speed of light bc then the speed of light obviously ain’t the fastest speed ever. Specially if a black hole if also move faster then the speed of light which is why it’s a black hole then therefore the speed of light is definitely not the fastest speed available
Yes, space in our solar system is expanding, however the distance between us and other planets in our solar system is infinitesimal compared the scale of the outer universe. To understand, say that the distance between planets doubles every 10 years (it definitely doesn’t) if you have planets 10 light years from one another, and another 100 light years. After 20 years passes, the first planet is 40 light years away now, as the space itself expanded. But the other Planet is now 400 light years away, as space itself is getting bigger, the larger the distance the more it expands. I tried to explain it relatively simply, sorry for any inconsistency.
I believe that in our perspective of time... "the big bang" just happed ... as in like 1000 of milliseconds. The reason I believe it "appears " to be speeding up is because we are observing it at still an early age. We re experiencing it as it just happened. if you like an explosive .. yes it's going to appear (if we could slow down time) that it's speeding up...because it is.. the force doesn't slow down right away.. it pushes out until the force is no longer a force.. I believe the "big bang" force has just begun. We feel as if it is almost over.. which then could appear to be slowing down. In other words a billion + years ago is like seconds to us... as where the bang could go trillions of years if not longer before it is observable as slowing if not longer.. It's just our perspective of time ;) If I light a stick of dyno mite next to an object... that object won't feel the force for 1000's of milliseconds before that force interacts with object because it's speeding up to that point in space... that's where I believe we are now
The universe was fine 13.8 billion years ago.... Then, nothing happened; it's been happening ever since, think about it. Where is all this "nothing" coming from
Right now dark energy is inferred using the Hubble constant, 70.5 km/s per megaparsec. Galaxies are spread out by a megaparsec on average. Each megaparsec comes out to be about 3,261,563.8 light years. If the universe is only 13.8 billion years old then how fast could galaxies be moving away from us after 13.8 billion years if the Hubble constant were correct? Well, 13,800,000,000 light years / 3,261,563.8 (1 Mpc = 3,261,563.8 light years) = 4,231 megaparsecs wide. So we multiply 4,231 megaparsecs by 70.5 km/s and we get a velocity of 298,292 km/s after 13.8 billion years. The speed of light is 300,000 km/s. Thus the furthest galaxy could only be moving away from us at a velocity of 298,292 km/s. 299,792 km/s - 298,292 km/s = 1,500 km/s. Thus, no galaxy after 13.8 billion years would be moving away from us faster than the speed of light if the Hubble constant is 70.5 km/s per megaparsec.
While your calculation using the ubble constant is insightful, it oversimplifies the complex nature of the universe's expansion. The universe's expansion isn't linear, so applying the Hubble constant uniformly over 13.8 billion years doesn't fully capture the reality. Due to dark energy, the universe's expansion is accelerating, not constant, which means distant galaxies can indeed appear to recede at superluminal speeds.
. Or is it a giant black hole at the center and we're being pulled back in faster than the light from the edges can catch up. Would have the same effect I believe...
You would be able to detect that if that was the case. Space expanding faster than the speed of light is based on the theorized age of the universe and the big bang theory. It's hard to admit that those are wrong is all.

@@stbaz Yes, that is what he is saying, and that soundbite is currently very common. But if the universe is 92 billion light years across, the furthest they can be now is 46 billion light years so we will (if we're still here) observe them as they are now sometime well before the year 46 billion AD. That's an awfully long time, but it's an infinity away from "never".
I find that a major problem in discussing topics like this one is that we do not use a universal definition of "now".
@@mimikurtz2162 interesting and I’ll have to keep thinking about this. Thanks 😊
And if there’s nothing faster then the speed of light. Then you can’t say that the universe is expanding faster then the speed of light bc then the speed of light obviously ain’t the fastest speed ever. Specially if a black hole if also move faster then the speed of light which is why it’s a black hole then therefore the speed of light is definitely not the fastest speed available
The idea of a big bang everywhere does seat well with me.
have a presentation soon, I am screwed
In 30 billion years the Big Rip will pop the universe like a balloon. All matter will rip apart including atoms. Time itself will cease.
If this theory is correct then space in our solar system is streching. Where are the measurements
Yes, space in our solar system is expanding, however the distance between us and other planets in our solar system is infinitesimal compared the scale of the outer universe. To understand, say that the distance between planets doubles every 10 years (it definitely doesn’t) if you have planets 10 light years from one another, and another 100 light years. After 20 years passes, the first planet is 40 light years away now, as the space itself expanded. But the other Planet is now 400 light years away, as space itself is getting bigger, the larger the distance the more it expands. I tried to explain it relatively simply, sorry for any inconsistency.
The expansion of the universe is different from the matter in it the expansion has no mass. Mass slows down everything..
Nothing tràvels in space, it's too compacted or its opposite day
Big Bang? Theory, nothing more.
What is mathematics founded on? seems to be in the dreamstate like everything else
I believe that in our perspective of time... "the big bang" just happed ... as in like 1000 of milliseconds. The reason I believe it "appears " to be speeding up is because we are observing it at still an early age. We re experiencing it as it just happened. if you like an explosive .. yes it's going to appear (if we could slow down time) that it's speeding up...because it is.. the force doesn't slow down right away.. it pushes out until the force is no longer a force.. I believe the "big bang" force has just begun. We feel as if it is almost over.. which then could appear to be slowing down. In other words a billion + years ago is like seconds to us... as where the bang could go trillions of years if not longer before it is observable as slowing if not longer.. It's just our perspective of time ;) If I light a stick of dyno mite next to an object... that object won't feel the force for 1000's of milliseconds before that force interacts with object because it's speeding up to that point in space... that's where I believe we are now
This is my theory does it seem to make sense.. lol :)
Well no one knows how big the universes are
We know how big the observable universe is. And also, we know how old it is since the big bang.
Never heard evanthorizon?
The universe was fine 13.8 billion years ago....
Then, nothing happened; it's been happening ever since, think about it. Where is all this "nothing" coming from

GRACIAS. Ya lo SABÍA 🤔😉😴😂😱😂😂 30.10.2024
Right now dark energy is inferred using the Hubble constant, 70.5 km/s per megaparsec. Galaxies are spread out by a megaparsec on average. Each megaparsec comes out to be about 3,261,563.8 light years. If the universe is only 13.8 billion years old then how fast could galaxies be moving away from us after 13.8 billion years if the Hubble constant were correct? Well, 13,800,000,000 light years / 3,261,563.8 (1 Mpc = 3,261,563.8 light years) = 4,231 megaparsecs wide. So we multiply 4,231 megaparsecs by 70.5 km/s and we get a velocity of 298,292 km/s after 13.8 billion years. The speed of light is 300,000 km/s. Thus the furthest galaxy could only be moving away from us at a velocity of 298,292 km/s. 299,792 km/s - 298,292 km/s = 1,500 km/s. Thus, no galaxy after 13.8 billion years would be moving away from us faster than the speed of light if the Hubble constant is 70.5 km/s per megaparsec.
While your calculation using the ubble constant is insightful, it oversimplifies the complex nature of the universe's expansion. The universe's expansion isn't linear, so applying the Hubble constant uniformly over 13.8 billion years doesn't fully capture the reality. Due to dark energy, the universe's expansion is accelerating, not constant, which means distant galaxies can indeed appear to recede at superluminal speeds.

The universe expands 327617.961 miles in 0.25 seconds. That’s 1/4th of a second. That’s 1.31e6 (1,310,471.844) miles a SECOND.
. Or is it a giant black hole at the center and we're being pulled back in faster than the light from the edges can catch up. Would have the same effect I believe...
You would be able to detect that if that was the case. Space expanding faster than the speed of light is based on the theorized age of the universe and the big bang theory. It's hard to admit that those are wrong is all.
@@noahbarkelew6093 I actually figured that would be the case but sometimes ya gotta toss a tinfoil hat in the microwave and see what arcs. Don't mind me, after a week of freezing my tail off fighting a cold but still having to chase down deposit drink cans to cash in I'm barely making sense to myself rn
There is no centre. Except for relative positions of individual galaxies the universe is the same from any location.
why do you guys treat big bang as if it's a fact...
Hello guys this was early explained by god in Holy Qur’an. The book that was descended a 1400 years ago, and the fate of the universe is also explained
That is the most ridiculous thing I’ve read today. Thank you for showing how brainwashed you were as a child.
I’m sure you’ll be able to provide the verse that explains this. Right?

This is all fine unless the cosmic expansion is an artifact of our measurements and observations. Please see the relevant paper entitled "Is the Big Bang an artifact?" (doi:10.5281/zenodo.11401298)
