00:00Friends, you all know that the universe in which we live, it has to end one or the other day.

00:07By the way, this is a very sad thing, but we humans have become so advanced that we have also found different ways to die.

00:16Through the current understanding of science, we have found a lot of interesting ways through which everything will end.

00:24The most important thing about these theories is that science has always introduced new theories about the end of our universe.

00:33For example, take the theory of vacuum decay.

00:36If vacuum decay occurs, the level of energy in the high field will change,

00:41due to which a bubble will form that will break all the rules of physics and will expand in the entire universe at the speed of light.

00:50In today's video, we will learn more interesting theories other than vacuum decay, so watch the whole video.

01:06Friends, as I told you that science always tells us different ways to end our universe.

01:13One of these theories is the theory of heat death.

01:16The idea of heat theory comes from the second law of thermodynamics,

01:19in which according to a version, the entire type increases in the isolated or closed system.

01:26Entropy is a measurable physical property that represents a disorder or an uncertainty.

01:33This means that in the isolated or closed system, uncertainty continues to increase.

01:39This happens when all the energy moves from the hot source to a place with less energy, such as the cold source.

01:48If this happens once, then no kind of work will be extracted in our universe.

01:54Due to this, the heat flow will also stop, the same will happen with the equilibrium state,

01:59due to which mechanical energy and electrical energy will stop.

02:04Now if no work will be extracted from the universe, then it is obvious that everything will be dead.

02:10You all know that we are dependent on different forms of energy to stay alive.

02:16If there is a change in one of these energies, then it will be very difficult for us to stay alive.

02:22This concept is very different from the core death theory.

02:25Core death happens when the universe continues to expand.

02:29Due to this expansion, our universe will keep getting colder and colder,

02:34due to which it will not be able to support any life.

02:37Here I tell you that the core death is not the opposite of the heat death,

02:42but its opposite is the Big Crunch.

02:44The Big Crunch theory is dependent on Einstein's theory of relativity.

02:49This means that if Big Bang tells us how our universe was formed,

02:54then Big Crunch will tell us how our universe will end.

02:58According to Big Crunch, the expansion from the Big Bang will not happen forever.

03:03Along with time, there will be a point when this expansion will stop

03:07and then it will collapse due to gravity.

03:10Now let's understand this with the example of a balloon.

03:13No matter how much energy is increased in it, it will never burst.

03:17We are filling gas from the cylinder in this balloon.

03:20As the air increases in it, the balloon will continue to expand.

03:25But as the gas in the cylinder decreases, this balloon will stop expanding

03:31and will come to its initial state.

03:33According to the Big Crunch theory, something like this will happen,

03:36but scientists do not prefer this theory much

03:40because according to the data so far, our universe is continuously expanding

03:44and it may continue to expand forever.

03:47Friends, all the theories are very interesting,

03:50but I have never seen anything as interesting as vacuum decay.

03:54According to this, a bubble will form anywhere in our universe,

03:59the laws of physics inside it will be very different from outside.

04:03This bubble will continue to expand at the speed of light

04:06and will take over our entire universe,

04:09due to which our entire physics will change or completely break.

04:14Due to the expansion of this bubble, galaxies move away from each other,

04:19atoms become unstable, and the attraction of particles also changes completely.

04:25To understand vacuum decay, we must first understand the vacuum state.

04:30For all of us, the vacuum state is outer space.

04:33This is also such a place where there is no matter of any kind.

04:36But let me tell you, outer space is not empty,

04:40but there is a fluctuating quantum field inside it

04:43which expresses such particles

04:46through which the fundamental laws of physics of our universe are formed.

04:49When these fields have very little energy,

04:52then they come into a vacuum state.

04:55But the meaning of vacuum state is not that it is completely useless,

04:59but because they live in their own state, they have made our reality.

05:04We know about such 17 particles that suddenly form.

05:08They form when the quantum field is excited,

05:12when this field receives energy, then it comes into an excited state.

05:17In these 17 particles, photons are also a particle,

05:20we receive it like light,

05:22and it also makes electromagnetic radiations,

05:25such as X-rays and micro rays.

05:28In addition to this, it also makes subatomic particles,

05:31from which protons and neutrons are formed.

05:33Other particles also form different types of forces,

05:36such as strong and weak nuclear forces.

05:39All these things are used to connect our universe.

05:43When all these quantum fields are in their vacuum state,

05:47then it can be said that our universe is stable.

05:50The vacuum state does not have to lose any kind of energy

05:54because if it changes,

05:56then the properties of fundamental particles will also change

05:59and the state in which our universe is running at this time will change completely.

06:04Friends, at this time, the quantum field is in a vacuum state,

06:07which means that it is stable at the moment and we are safe,

06:11but it is very difficult to measure this quantum field

06:15and it may be that the quantum field does not reach the vacuum state.

06:19Here I tell you,

06:21due to the high field and its associated high position,

06:26today there is mass in all things.

06:28According to scientists, the high field has risen to a special energy level.

06:32Here I tell you,

06:34Scientists say that the high field is still far from its vacuum state

06:39and it may go towards its vacuum state in the future.

06:43Here you are thinking that what is the problem in this?

06:47So let me tell you,

06:48the state in which the high field is present at the moment,

06:51our universe and its last depend on it.

06:54Now if there is any change in it,

06:56then there will be a lot of destruction.

06:59Scientists say that to bring the high field into its vacuum state,

07:03a lot of energy will be used.

07:05If the high field somehow comes out of this state and reaches its true vacuum state,

07:11then the physics of our universe will change forever.

07:14The high field came out of its false state just like a domino effect

07:19and we call it vacuum.

07:20The bubble of this vacuum decay will begin to spread at the speed of light throughout the universe.

07:25As it passes through other matter,

07:28the force of our universe will stop working.

07:31What will happen after this?

07:32No one knows about it.

07:34But what do you think about it?

07:36Do tell by commenting below.

07:38If you like the video, then like it and also come and share it.

07:42See you in another amazing video.

07:44Take good care of yourself.

07:46Allah Hafiz.
