How big would the sun need to be if it were a black hole?

The Sun would need to be about 20 times more massive to end its life as a black hole. Stars that are born this size or larger can explode into a supernova at the end of their lifetimes before collapsing back into a black hole, an object with a gravitational pull so strong that nothing, not even light, can escape.

What would happen to Earth if the Sun 1 M ⊙ suddenly collapsed to form a black hole?

The Earth would become very cold and very dark which of course goes without saying. If the sun compressed itself into a black hole it would be around 3.5 miles in diameter but would still have the same gravitational pull as the sun has now. Signicantly smaller diameter but with the same gravitational force.

What happens if a black hole hits Earth?

What would happen, hypothetically, if a black hole appeared out of nowhere next to Earth? The edge of the Earth closest to the black hole would feel a much stronger force than the far side. As such, the doom of the entire planet would be at hand. We would be pulled apart.

Is Sun a black hole?

No. Stars like the Sun just aren’t massive enough to become black holes. Instead, in several billion years, the Sun will cast off its outer layers, and its core will form a white dwarf – a dense ball of carbon and oxygen that no longer produces nuclear energy, but that shines because it is very hot.

What would a black hole look like in outer space?

Imagine that you are in outer space directly above the black hole, looking at the black hole that is on the earth’s surface. Can you imagine what it would look like? It would simply be a hole with the surrounding light gravitationally lensed around it (possibly lensing the entire earth if it’s big enough – but let’s say it’s not).

How fast does a full sized black hole travel?

Exploring a Full Sized Black Hole 6-8 6 A Scale-Model Black Hole – Orbit speeds 6-8 7 A Scale Model Black Hole – Orbit periods 6-8 8 A Scale Model Black Hole – Doppler shifts 6-8 9

How to understand black holes in math?

Amazingly enough, many aspects of black holes can be understood by using simple algebra and pre-algebra mathematical skills. This booklet fills the gap by presenting black hole concepts in their simplest mathematical form. General Approach: The activities are organized according to progressive difficulty in mathematics.
