Answer 》
Q . 1 》Are dimensions and galaxies same ?
Ans 》 Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across. That sounds huge, and it is, at least until we start comparing it to other galaxies. ... Another galaxy, IC 1101, spans as much as 4 million light-years.
Q .2 》 can the closest black hole to the earth.. swallow earth if it grow?
Ans 》 Probably not. Despite their large mass, stellar black holes only have a radius of around 300 kilometers or less, making the chances of a direct hit with us miniscule. Although because their gravitational fields can affect a planet from a large distance, they could be dangerous even without a direct collision.
Q . 3 how fast can a black hole grow?
Ans 》 Our numerical calculations show that the process of dynamic migration and fusion of stellar black holes can make the supermassive black hole seed reach a mass of between 10,000 and 100,000 times that of the Sun in just 50–100 million years,” Lapi explains.

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!
