Why did the solar nebula shrank in size?
As the cloud shrank, its gravitational potential energy was converted to kinetic energy and then into thermal energy. Why did the solar nebula flatten into a disk? It flattened as a natural consequence of collisions between particles in the spinning nebula, changing random motions into more orderly ones.
How old is the solar system?
4.571 billion years
What force caused the solar system to form?
gravity
What shape is an irregular galaxy?
An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. Irregular galaxies do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.

Which is the largest thing in the universe?
The largest known structure in the Universe is called the ‘Hercules-Corona Borealis Great Wall’, discovered in November 2013. This object is a galactic filament, a vast group of galaxies bound together by gravity, about 10 billion light-years away.
What is the most powerful thing on earth?
Take the world’s most powerful computer, the IBM Roadrunner. With the ability to process 1 million billion calculations per second, this supercomputer has the strength of 100,000 MacBooks combined.
What is the most beautiful thing in the universe?
A: “The most beautiful thing in the universe is the human ability to comprehend it. “Our universe is extraordinarily complex, with processes occurring on all scales, from the subatomic world to the universe at large.
What is the dangerous thing in the whole world?
Of all the species in the world, the largest—and most dangerous—is the saltwater crocodile. These ferocious killers can grow up to 23 feet in length, weigh more than a ton, and are known to kill hundreds each year, with crocodiles as a whole responsible for more human fatalities annually than sharks.
What is the strongest explosion in the universe?
Astronomers have spotted a cosmic blast that dwarfs all others. A gargantuan explosion tore through the heart of a distant galaxy cluster, releasing about five times more energy than the previous record holder, a new study reports.
What happens to an explosion in space?
If a nuclear weapon is exploded in a vacuum-i. e., in space-the complexion of weapon effects changes drastically: First, in the absence of an atmosphere, blast disappears completely. There is no longer any air for the blast wave to heat and much higher frequency radiation is emitted from the weapon itself.
What is the most powerful star?
The biggest: UY Scuti But if it had started its life with a dozen or so times its current mass, it could have eventually evolved into a red supergiant. (UY Scuti has already shed a lot of mass.) The biggest of these stars, sometimes called hypergiants, can swell to more than 1,000 times the size of the Sun.
What is the hottest star color?
Blue stars
What is a Starquake?
Starquakes create cracks that allow astronomers and astrophysicists to peer inside stars. By Richard Gallagher | March 11, 2020. Conny Aerts, of the University of Leuven, says quakes creates waves that lets them measure gases inside stars, their density, temperature, chemistry.
What is the biggest magnet in the universe?

What is the strongest non electric magnet?
Developed independently in 1984 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet available commercially.
