Late Physicists Stephen Hawking’s greatest breakthroughs on Black Holes and Event Horizon

As per Hawking, if a tiny black hole radiates much energy quicker, the phenomenon can be observed first-hand. Paul stated how Hawking said that he would win a Nobel Prize for his discovery if such a phenomenon is observed practically.

Stephen Hawking's greatest breakthroughs: Black holes, event horizons & more

Stephen Hawking, one of the celebrated theoretical physicist who published around five breakthroughs over the years in his career spanning more than 50 years. His last research paper along with a co-authored was finally revised and submitted just 10 days before he took the last breathe at his home in Cambridge on March 14. Professor Paul Shellard who will be taking over as the director of the Centre for Theoretical Cosmology department at the University of Cambridge which, Hawking was instrumental in establishing, shared snippets of various theories Hawking proposed. The center was developed with the aim to develop theories based on observational testable and scientifically consistent objectives.

As per Shellard, Hawking wanted to achieve something that would be astounding for the rest of the scientists in the physical theory. For instance, he proposed his breakthrough on reconciling two major ideas. The first was quantum mechanics which expresses the uncertainty and disturbance on an extremely small scale while on the other hand, he established a connection with Einstein’s relativity theory which studies pretty much every large scale objects in the universe that includes stars, black holes, and galaxies, etc

Stephen Hawking expressed his theory based on the model of black holes where he explained the event horizon i.e. the point of no-return and that it hides away the singularity where the latter is a point in space which has a density to infinity so much that even light couldn’t escape it.

He even explored the process of production of symmetric pairs of particles and antiparticles which is what quantum theory states about and that it exists across the Universe. Do you know that antiparticles are considered the best fuel to power future interstellar spacecraft due to his 100% mass to energy conversion, however, it is also the most expensive element in the universe and it takes a great deal of time and efforts to even mimic a nano amount of it?

Moving further, he pointed out that a black hole irrespective of how much black it appears is not entirely black. It emits some particles that could fluctuate and escape the black hole and that process is known as Hawking radiation. It explains why a black hole emits energy slowly so that it can conserve energy for later. The Theory of Everything that Hawking proposed was an idea coined in 1974, however, even now, researchers are studying and developing new ways that would enable them to finally observe it practically.

As per Hawking, if a tiny black hole radiates much energy quicker, the phenomenon can be observed first-hand. Paul stated how Hawking said that he would win a Nobel Prize for his discovery if such a phenomenon is observed practically. Since 2010, many researchers have been conducting their research on creating an analogy of black hole to study Hawking Radiation and it is one of the active areas of study.

His latest observations were with respect to the Event horizon where he stated that our universe can have an event horizon and since the universe is expanding, it is referred as inflation. It is similar to that of black holes. He cited that during the process of expansion, it creates tiny ripples in the early universe which later became the seeds for the origin of celestial bodies like stars and planets, etc. He coined the term Inflationary fluctuation which has been studied by few satellites who glanced at the early days of the universe.

Stephen Hawking another breakthrough was when he proposed that when two black holes collide, the area of the event horizon always increases that would increase the gravitational pull exerted by the black holes. He found it analogous to the second law of thermodynamics. Although this theory dates back to 1960s and 1970s, it was only possible to observe it in February 2016 when experiments on disturbances in the fabric of space-time were recorded due to accelerated masses.
