What did Stephen Hawking say about technology?
Hawking’s biggest warning is about the rise of artificial intelligence: It will either be the best thing that’s ever happened to us, or it will be the worst thing. If we’re not careful, it very well may be the last thing.
What did Hawking invent?
Dr. Hawking is best known for his discovery that black holes emit radiation which can be detected by special instrumentation. His discovery has made the detailed study of black holes possible. Stephen Hawking was born in Oxford, England on January 8, 1942.
What is the greatest invention of Stephen Hawking?
Hawking was the first to set out a theory of cosmology explained by a union of the general theory of relativity and quantum mechanics. He was a vigorous supporter of the many-worlds interpretation of quantum mechanics.
What would happen if a supernova hit a black hole?
If you get a black hole with a small enough mass, it will evaporate in a short time. It is thought that the minimum mass of an astrophysical black hole created by a supernova explosion would be a few solar masses. A black hole with a mass of around 1 solar mass will evaporate in around 2×1066 years.
Can neutrinos kill you?
If you observed a supernova from 1 AU away—and you somehow avoided being being incinerated, vaporized, and converted to some type of exotic plasma—even the flood of ghostly neutrinos would be dense enough to kill you. If it’s going fast enough, a feather can absolutely knock you over.
Will a supernova destroy Earth 2022?
Risk by supernova type Although they would be spectacular to look at, were these “predictable” supernovae to occur, they are thought to have little potential to affect Earth. It is estimated that a Type II supernova closer than eight parsecs (26 light-years) would destroy more than half of the Earth’s ozone layer.
Is Betelgeuse bigger than the sun?
Betelgeuse, a red supergiant star roughly 950 times as large as the Sun, is one of the largest stars known.
Who is the biggest star in the universe?
Answer: The largest known star (in terms of mass and brightness) is called the Pistol Star. It is believed to be 100 times as massive as our Sun, and times as bright! In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy.
How big is Betelgeuse compared to Earth?
Between small planets in the solar system and the biggest stars, the size difference is enormous, for example, the diameter of the star Betelgeuse is 141,863 times larger than the diameter of the Earth.
Who is Big Earth or star?
Yes! In fact, most stars are bigger than the Earth. The diagram below compares the size of our sun with the sizes of the other planets in our solar system. The sun is much bigger than the Earth, and it isn’t even a particularly large star.
Is a galaxy bigger than a universe?
Galaxies come in many sizes. The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them! Our Sun is one star among the billions in the Milky Way Galaxy.
How many Earths fit Betelgeuse?
Betelgeuse would engulf all four terrestrial planets — Mercury, Venus, Earth and Mars — and even the gas giant Jupiter. Only Saturn would be beyond its surface….About the Image.

How many times star is bigger than Earth?
It is 864,000 miles (1,392,000 km) in diameter, which makes it 109 times wider than Earth.
What star is bigger than Uy scuti?
Thus we don’t know its size exactly, and the true range might between 1,642 to 2,775 solar radii. The upper part of the range would make it larger than UY Scuti. Another hypergiant star is WOH G64, also in the Large Magellanic Cloud, and thus located at a distance of some 168,000 light years from Earth.
