Do Black hole die|hawking radiation|virtual particles|

The answer is yes,for that you have to know what is black hole?,so check out this link about black hole.


https://mysteryunlocked2020.blogspot.com/2020/02/what-is-black-hole.html

So ,till 1974 scientist believed that black hole are immortal since they don't emit radiation.But in 1974 a  an English theoretical physicist, cosmologist Stephen William Hawking proposed his theory that black holes also emit radiation.

He identity this by combining quantum mechanics and general theory of relativity.
He said that the blank space in our universe are not actually blank but ,collision of virtual matter and its anti matter and they both disappear,.

So ,like other parts of the universe ,at the event horizon there should be virtual masses forming and one goes to the singularity and other pops out from black hole as gamma radiation.so this radiation was termed as hawking radiation,in the honored of his discovery.

f black holes evaporate under Hawking radiation, a solar mass black hole will evaporate over 10⁶⁴ years.A super massive black hole with a mass of 10¹¹ (100 billion) M_☉ will evaporate in around 2×10¹⁰⁰ years. Some monster black holes in the universe are predicted to continue to grow up to perhaps 10¹⁴ M_☉ during the collapse of super clusters of galaxies. Even these would evaporate over a timescale of up to 10¹⁰⁶ years.

In June 2008, NASA launched the Fermi space telescope, which is searching for the terminal gamma-ray flashes expected from evaporating primordial black holes. In the event that speculative large extra dimension theories are correct,

At  its end time there will be a huge blast of gamma rays takes place.

Parallel universe|Alternate realities|time travel|black holes|H.G Wells|Hyper space

On our previous topics  we teased parallel universe ,so what are they actually and why we need to known about them.

Parallel universe are alternate realities which have different types of possible event occurrence.Scientist believe that like our galaxies are inside a space bubble ,there will be many universe space bubble which are nearly centimeters from our universe in an whole space time space.

I think you have a bit of confusion state ,let me explain in a simpler way.Imagine you have a sphere ,that sphere is the hyper space time ball and inside the sphere there will be molecules which we consider as a universe,like our universe there are infinite number of universe exists.

For example you can be a president of america in one universe ,whatever comes to your mind there is 100% chances of occurring in some other universe.

Another proof that scientist put forward of parallel universe exist is the amount of dark matter present in observable universe

This amount is 5 times more than normal matter,thus they predicted that some bigger universe should be located near our universe and dark matter are being from that leaked and reach our's.


TIME TRAVEL CAUSES PARALLEL UNI VERSE TRAVELLING:

H.G Wells the famous author mention in his book  "TIME TRAVEL" which was published in 1985 that on time travel instead of changing our reality we go to alternate realities,or alternate universe.

Its is because our universe has a particular space time lane and if we somehow manage to time travel we need to get release from our space time and start travelling.

There will be no problem of going to alternate realities until you change anything in past or future.

So instead of time travel errors ,can we make a portal to parallel universe.

The answer is yes but no:

Why I said yes is that scientist believe that if we eject 85000 watt beams of neutrons towards a wall, there is a chance of one neutron passing through the wall thus creating a hole to parallel universe.

For reason of saying no ,you should have probably guess it, that is this portal is extremely small that you should reduce your size to any atom to travel through this portal.

Another thing is that if we go inside a black hole we might probalbly being thrown by any another black hole of different universe

Earth 2.0|super earth|Kepler 452b|why it is termed as second earth|NASA|wormhole| space telescope Kepler|

In 2015 Kepler space telescope found any earth like planet which is 60% bigger than earth.

you would  ask how you say it has same like earth living?

For that you have to know about habitable zone, this zone is where if  any planet has its orbit will have temperature which is suitable for living ,this zone will generally depend upon the mass and size of the host star in that solar system .For instance sun the has its  habitable zone at earths orbit ,so makes earth a habitable planet

Okay now lets come to topic, how come NASA identify this planet and why do they name it as Kepler 452b

It all started at  March 7, 2009 where NASA send a space telescope to capture different solar system and study about planets in it and check whether they are earth like planets exists.

How a space telescope studies the planets is that :

1.First it capture the light from a star.

2.Then if gets a decreased intensity of light from the same star once every 365-400 days ,it is understood that some planet should have crossed it.

3.After that further study of that planet will takes place

In 2015  after studying 451 planet ,the 452 planet has specification nearly same as earths .For example it orbits in  habitable zone of its host star which is 6 million years old and has only 3.7% more massive and has same mass as sun.

Second thing is that this planet have shows a light glitch for every 385 days this means that 385 days = 1 year or 1 revolution of that planet.

 

 Last and important thing is that even water also exist in that planet and scientist believe that this planet has its own atmosphere too.

So you got the answer why i termed this planet as earth 2.0 or super earth.So lets pack up and have space travel.

But the problem is that it is 1400 light years from earth.so imagine that we go to that planet with a speed of light .It takes nearly 14-16 gen to reach that planet and your 17th generation will live that.

So all our efforts are waste,what to do now,Don't worry .

We can't go to that planet but our future generation if some how able to create a wormhole ,then it takes a matter of time to reach there

One way to time travel||predictors|Nostradamus|brain travel|Mayans|why we can't do time travel by travelling at speed of light

You know many scientist search about time travel for decades,but thing is that we failed most of the times

Many people say that we can time travel by travelling at a speed of light but that's not the case,
even you go at the speed of time your can't time travel,instead you can be teleport . Its is because earth has its own space time bending and even light follows it.

So to do time travel you need to get escape from the space time dimension,for those who don't know space time check out my previous blog

Now lets come to the point ,then how can we pursuit time travel there is way to achieve this ,for that i ask you a question you all know about Nostradamus ,he is world popular predictor of future , people say that he had visions of future by concentrating a candle flame for many hour. So how?

But the thing is that I believe to be is that while he concentrates one a flame is mind stops diverting and focus on one thing that is future ,so this is brain instead of multi functional task works on a single functional task ,this triggers his subconscious mind and show him some visuals that he believe to be future.

This is were he breaks the space time of the earth,so he achieve time travel not physically but mentally.that is the point that i want to say. your brain is the tool for time travel. we can take many examples in India where if you go and meet saints in kasi or some other place they predict your future by not astronomy but instead closing there eyes and predict it which mostly be correct.


Lets see how our brains make you to time travel, do you now that we still able to use only 12% of our brain .so we if able to use our brain's full potential, there comes the real reality, our brain will be directly concentrate the cosmic energies or space energy and so we can do many things such as parallel universe travel ,time travel.

One thing you need to know to energy can be transfer or replace ,so we will become a energy source more like we don't have a physical form ,we will be in our soul form.

Instead of 100%percent lets go to some 30 % percent, it time to we can able to time travel but we can't to parallel universe travel.

So at this time we can able to shift our particles otherwise our brain can control up to atom scale of your muscles.by this you can shift your size to smaller than atom and access quantum realm without any machines.

So this why our religions focus on brain activity,all there assumptions were from there visuals of subconscious mind which there frequently access by meditation .

Imagine your brain connects to computer?how it will be?|neuralink|Elon musk vision|advantages and disadvanges|

So lets have a day dream , imagine that you have a superpower to just to control all electronic devices around example your TV,mobile phone and you can also can store your memories in a computer,that would be awesome but you would say this can't happen in reality,but truth is that it can .

So is possible to connect our brain with electronic devices any proof ?

Here there are :

1.The 28-year-old man, who has been paralyzed for more than a decade after a spinal-cord injury, had electrodes from the prosthetic hand inserted into his sensory and motor cortex's. This allowed him to both control the hand with thought and sense when the fingers of the hand were touched individually. 

check out the video 

https://www.youtube.com/watch?v=xynE-43trQg&feature=emb_logo


2.In 2015 Nankai University in Tianjin develop a headset which has 16 sensors to read electronic signals from brain and used them to control a cars movement.

You would only need to concentrate on the thought when you want to actually change the status of your vehicle - something you do unconsciously anyway

so the advance version of this is gonna come in future that is we can able to store our memories and emotions and connecting our brain to internet.This idea was startup by elon musk in 2017 he named this project as neuralink , in that he stated that by using brain implant machines we can connect our biological Neal codex and  digital Neal codex. that is connecting brain with computer by implanting a chip inside your brain,this chip will be at nano scale (which is 10power-9 meter ) .   

Musk's company Neuralink is building tiny and flexible 'threads' which are ten times thinner than a human hair and can be inserted directly into the brain this is called as neuralace

So what are the advantages and disadvantages which it comes to neuralink

Advantages:

1. You can able to store your good memories with your loved ones in your pc 

2. No education is needed to world as our brains is connected to internet.

3. Less hand work , more brain work.

4. You can tune your emotions as you wish , that is you can remove short temper and replace with calm one.

Disadvantages :

This comes when someone hacks your brain interface , since we are connect with mobiles or pc, a simple malware a can lead to big privacy leaks.

cyber war will happen by  brainwash many people easily(just simply tune your emotions like a psycho killer one that is anger ,depressed and use you as a killing machine.

There will be no privacy any more


So one conclusion is that this technology is more valuable and need more high level of security

What is the brightest thing in the universe?Is it a star or a galaxy or something else?

when you see the title you should have guess that it would be a red giant or a galaxy.But the thing is that  you are actually wrong .

The worlds brightest object is quasar. so what are they ?how to they form?how we find  them? . Lets see  one by one

Quasars are formed when two super massive black hole (they generally have billion times the mass of sun) combine together releasing a super jet of energy and matter.

Sounds fishy right ,that is the complexity of space , we heard a proverb that is 

When we compare it to our topic we see that the darkest thing (singularity of black hole) combine to form a  brightest thing in the universe.

Wait a minute we all know that even light can't escape from black hole then how come a combine form of two super massive black hole let the surrounding mass escape.

First thing is that these mass are the junks around the event horizon of each black hole or it can be be the nearby stars get sucked when two black holes combine and there will be a huge magnetic field around the black hole because each black hole rotates while combining and the final black hole will be a rotating one.This magnetic field causes the matter around the event horizon to eject like a super jet  with 1/3th of speed of light

So we completed the origin of quasar ,now we move on how scientist identified them

this all happens in 1960 when the worlds first radio waves observatory identified a peculiar reading . they observe some spectral lines having rapid luminous intensity in optical range and even more in x ray range.

On further detail analysis they found that these should have come from the source which is located billions of light years from us . They termed this radio waves they get as quasar stellar radio waves and source as quasar.

After that on years of analysis they found that this quasar was emitted from two massive black hole when our universe is 690 million years old .
They estimated the luminous intensity they emitted is to be billion times brighter than our milky way.

Fun Fact:

Scientist estimated that in future two super massive black holes(one is from our milky way galaxy which is Sagittarius and another from Andromeda galaxy) combined to created quasar , this event  will happen few billion years from now. So chill

What is a black hole?

Even you are not a cosmology student you should have heard about black hole,previous year we got a image of it to.So what are they?How we find them?How do they actually look like?Lets discuss first lets come to the origin, they are formed by explosion of a star called as super nova when its core become unstable.

So you have a doubt that even our sun is a star this means that our sun will also become a black hole at its last stage.But the thing is that for a star to become a black hole should have a mass 20 times that of our sun.

Even though they have such mass they should have a core mass size 1.4 times of the sun after supernova explosion else there will become a neutron star.

So this is how black hole forms ,now lets see how to they look like

This image is a theorized image of Einstein relativity theory ,in this the outer circle is termed as event horizon and if something cross this region will be sucked by the black hole's singularity.

So what is a singularity?

It is the point where all the mass a compress to a single point .This means that volume will become zero

We know that d=m/v, then density becomes infinity.

This makes a black hole have extreme gravitational force so that even light can't escape from it

One fun fact :

 Consider that your friend crosses the event horizon and you see him from a distance telescope. at this time your friend will be sucked into pieces but you see him just 

staying in event horizon .

This is because since the black hole bend space time extremely . the time around will be slow then yours and the radio waves from him will take years to reach you.

So now see how can we take a picture of it

As i said that even light can't able to escape from it so how come scientist were able to take a picture of it.

There are two ways

1  When a star get suck or change in its speed due to black holes immense space time bending

2 .Next is that recording the radio waves  from the gases which are located at its event horizon.

 This was the method used by scientist to get a image of a black hole on April 10 2018 which is located 55 million light years from us.

The detail of how they capture will be explained tomorrow .stay tuned
