does stephen hawking believe in dark matter? In the 1970s, Hawking proposed that dark matter, the invisible substance that makes up most matter in the cosmos, may be made of black holes formed in the earliest moments of the Big Bang.
What was Stephen Hawkings theory? Stephen Hawking worked on the physics of black holes. He proposed that black holes would emit subatomic particles until they eventually exploded. He also wrote best-selling books, the most famous of which was A Brief History of Time: From the Big Bang to Black Holes (1988).
What is Stephen Hawkings black hole theory? A central law for black holes predicts that the total area of their event horizons – the boundary beyond which nothing can ever escape – should never shrink. This law is Hawking’s area theorem, named after physicist Stephen Hawking, who derived the theorem in 1971.
What is dark energy in physics? Dark energy is the name given to the mysterious force that’s causing the rate of expansion of our universe to accelerate over time, rather than to slow down. That’s contrary to what one might expect from a universe that began in a Big Bang. Astronomers in the 20th century learned the universe is expanding.

And there is so much dark matter overall that the secondary kind could weigh as much as all of the visible parts of the universe. “The fact that nobody had thought about this before is incredible,” Randall says.
where can dark matter be found?
The answer is gravity. Astronomers indirectly detect dark matter through its gravitational influences on stars and galaxies. Wherever normal matter resides, dark matter can be found lurking unseen by its side.

What will happen if species keep going extinct?
According to a study for the U.N., the continued loss of species could cost the world 18 percent of global economic output by 2050. Already, a number of industries have been economically impacted by species loss. The collapse of bee populations has hurt many in the $50 billion-a-year global honey industry.
