Black hole | White Hole | Wormhole

Portals- oh...OMG portals.........

I know you also get amazed like that only after reading about portals.

So let's discuss about it 

• Wormhole

          

           Wormholes are also known as Einstein-Rosen bridge. It was discovered by Ludwig Flamm in 1916. It was rediscovered by Albert Einstein and his colleague Nathan Rosen, they published their research in 1935.

Wormhole is a short-lived portal, lasting only a brief moment, that joins two coordinates of space-time, two black holes. It could connect points of present day universe or perhaps, in different times.

Wormhole is a highly speculative idea of modern physics.

According to wormhole theory, matter which falls on wormhole should emerge from white hole (opposite side or reverse of black hole).

But the fact is that wormholes haven't discovered yet.

But wormhole for magnetic field has prepared in laboratory on 2015 in Spain.

Wormholes can be used to perform time travel. Wormhole can connect two different points of present day or with any other time.

Wormholes are extremely small in size. To use it, exotic matter will be required.

Sir Stephen Hawking has contributed to this theory a lot.

Wormholes can be created by creating two entangled black holes and then increasing distance between them.

• Black Hole   

 

           Black hole  was found by Karl Schwarzschild in 1916.

 Black Hole forms when large, dying star collapse.

Matter of star get that much condense which results in very powerful gravitational force.

The gravity is that much strong such that even light could not escape from it's pulling force.

It has so much gravitational force that it slows down the time near it.

Matters get started stretching when came close to event horizon (outer part of black hole).

Types of black holes-

       1• Stellar Mass Black Hole

                 It has mass few times greater than our sun. It is formed from collapsed cores of giant stars.

      2• Intermediate Mass Black Hole

  

                 It is 100-10,000 times more massive than our sun.

      3• Supermassive Black Hole

        

                  It is largest type black hole. It inhabits at cores of galaxies. It is billions times larger than sun.

      4• Primordial Black Hole

                  It is smallest black hole formed in early universe soon after big bang.

Black Hole has that much mass and gravitational force that it can slows down the time. That's why it can be used for time travel. If we just take a round of black hole than we will be in future with respect to our earth.

Black hole can be a way to other dimensions.

Black holes can't be seen by optical telescope. Black holes get detected by the disk of surrounding materials funnelled by its gravitational force.

Scientists have developed sonic black hole.

• White Hole

          

          According to general relativity, a white hole is a hypothetical place of singularity and space time where entering from outside is not possible.

In fact white hole is considered as opposite end of black hole. From white hole things comes out.

But light, energy-matter can escape from it.

In 2014, Carlo Rovelli, a theoretical physicist at Aix-Marseille University in France, and his colleagues says that when black hole dies, than white hole formed.

When black hole evaporates to a degree from where further shrink of space-time is not possible then it rebounds to white hole.

White holes can be used to understand dark matter.

Dark matter and dark energy will be discussed later.
