Hawking radiation is one of the most striking works of Professor Stephen Hawking, helping decode the black hole and the origin of the universe.
Professor Stephen Hawking has dedicated his life to finding answers to the most cosmic questions. What is that?
What exists at the center of the black hole?
Black holes are objects with odd material density, their gravity is so great that light cannot escape.
According to research by Stephen Hawking and physicist Roger Penrose, if you can travel inside the center of the black hole, you will find something called the singularity.
At the singularity, an enormous amount of material is compressed into a small space, causing gravity there to become infinite and everything falling into it is crushed.
What happens at the edge of the black hole?
Maybe you think, vacuum is a space that does not contain matter. However, this is not true, at least not in accordance with quantum theory.
The vacuum always has fluctuations between particles and antiparticles. At the edge of the black hole, when the outer particles are sucked in, the particles inside will escape. These outflow particles are a form of energy radiation, called Hawking radiation, which causes the black hole to shrink and disappear.
This process takes place over a very long period of time, but eventually they will explode and release energy equivalent to a million through the atomic bomb, erasing all traces.
Stephen Hawking showed that everything in the universe originated at a singular point and then exploded (Big Bang explosion) to form galaxies, stars, planets, people and everything that existed. . That is the beginning of the universe.
In fact, Elon Musk’s satellite internet package: costs only 9.99 USD, speed of 1 million Mbps
There are rumors that Elon Musk has now started selling global internet packages for only $ 9.99 to $ 29.99 but speeds up to 1 million Mbps.
Currently, there have been rumors that SpaceX’s CEO – Elon Musk with the success of the high-speed internet satellite launch at the end of February sold this global internet package.
Accordingly, this satellite internet package will be sold to all residents on Earth and … those who want to travel out of space. The price of this package will range from $ 9.99 to $ 29.99.
The price of this package will range from $ 9.99 to $ 29.99.
The cheapest basic package, the StandardX, costs $ 9.99, which will be available at 1,000 GB per month at a rate of 10,000 Mbps and can be texted with short global content.
The more advanced package, PremiumX, is supplied with 2,000 Gb capacity per month at 20,000 Mbps, with unlimited messaging support worldwide. This package costs $ 19.99.
The strongest network called ProfessionalX is priced at $ 29.99. Users of this package will be able to use the internet without capacity limitations at super fast speeds of 1,000,000 Mbps. According to Elon Musk, this premium package is a vision for the future to provide Internet for … other regions in the galaxy.
For those who do not know, SpaceX’s satellite named Tintin A and Tintin B was successfully tested in late February, opening up great hopes for the project to launch 12,000 satellites that broadcast high-speed internet bandwidth. of this company in the future.
If this project is successfully implemented, it will provide a speed-up internet network 180 times higher than today for users worldwide. According to SpaceX’s plan, by the end of 2019, 4,000 internet satellites will be launched into space. These satellites will orbit the Earth from 1,100 – 1,200km and are supported by 7,500 spacecraft at lower orbit.
