Do smaller black holes have more gravity?

Stellar-mass black holes are puny in comparison to their bigger cousins, but they actually boast the strongest tidal forces of any type of black hole. That’s because smaller black holes actually have a more intense gravitational gradient than larger ones.

Do bigger black holes have more gravity?

The gravitational field of a black hole is proportional to its mass. So all else being equal, if you are at the same distance from a more massive black hole, there is more gravity. Larger black holes have larger mass, lower temperature, higher entropy, and lower surface gravity (at their event horizons).

Why is the gravity from a black hole greater than the gravity from the star that it came from?

Because black hole have infinite density at center of it. So unlimited spacetime curve. Or gravity well is like that even light can’t escape. Whereas star never have that much density.

Do black holes have surface gravity?

In fact, the surface gravity of a general black hole is not well defined. However, one can define the surface gravity for a black hole whose event horizon is a Killing horizon.

Why do black holes get bigger?

Supermassive black holes (SMBHs) are much, much larger, on the order of millions to billions of solar masses. One possibility is that they form in their host galaxy, then grow bigger and bigger by slurping up a whole lot of stars and gas and dust, and collisions with other black holes when galaxies merge.

What is Earth’s surface gravity?

9.807 m/s²
Earth/Gravity
The nominal “average” value at the Earth’s surface, known as standard gravity is, by definition, 9.80665 m/s2 (about 32.1740 ft/s2).

Why does a black hole have such a high gravity?

A black hole has high gravity because it literally is the result of the gravitational collapse of a very massive star (though there can be other processes involved). Anything with mass produces gravity, and the more mass, the stronger the gravitational pull.

What is the difference between super-massive and stellar mass black holes?

Stellar mass black holes are much smaller in size than super-massive black holes, so the difference in gravity between say a persons head and feet is smaller. Imagine doing chin ups, now with somebody else hanging onto you feet, then 10 people the population of London.

How dangerous is it to go near a black hole?

All black holes are dangerous if you get close enough, but smaller ones are more dangerous because they cause stronger tidal effects, so they can cause spaghettification well before you reach the event horizon, whereas you can cross the event horizon of a supermassive black hole without the tidal effects becoming noticeable.

What would happen if the Sun became a black hole?

Instead, the Sun will become a dense stellar remnant called a white dwarf. But if, hypothetically, the Sun suddenly became a black hole with the same mass as it has today, this would not affect the orbits of the planets, because its gravitational influence on the solar system would be the same.
