How fast does a black hole expand
WebNo, a 1kg mass would not turn into a black hole, even if it were zipping past you at very close to the speed of light. The principle of relativity is a fundamental idea in physics, and one consequence of it is that we can understand the physics of something that's moving by imagining we're moving alongside it.

Web22 jul. 2014 · Black holes are so massive that they severely warp the fabric of spacetime (the three spatial dimensions and time combined in a four-dimensional continuum). For … Web28 dec. 2015 · 7. Most † black holes are indeed expanding, but not because the Universe is expanding. Rather, their size (more precisely their Schwarzschild radius) increases proportionally to their mass, so they grow as they accrete more matter. It is a common misconception that everything expands along with the expanding Universe. It doesn't.
Before Stephen Hawking came up with the concept of Hawking radiation, the question of black holes having entropy had been avoided. However, this concept demonstrates that black holes radiate energy, which conserves entropy and solves the incompatibility problems with the second law of thermodynamics. Entropy, however, implies heat and therefore temperature. The loss of energy also implies that black holes do not last forever, but rather evaporate or decay slowly. Bl… WebStellar black holes can move through space at a low end of 45 miles per hour. This is the linear velocity of forward (non-rotational) movement of a stellar black hole not the …
Web15 nov. 2024 · It takes just a few seconds for two spiraling black holes to merge, so assuming a static universe over that short time frame, as past work has done, seems … Web13 feb. 2013 · They orbit the black hole in a lightning-quick 20,000 miles per second, over a tenth of the speed of light.

WebI presume the answer is that it depends on the mass and size of the star and black hole and how they approach either other, but I was wondering if somebody could provide some rough bounds (e.g. hours vs thousands of years) theorized or based on historical observed data.

However, light has no mass so it is not accelerated by gravitational forces. Even when light travels on a curved path it does so at the “speed of light” which is a universal speed limit.

Mass still falls into a black hole, it's just that from the point of view of the mass, its last instant outside of the hole is infinitely long. The mass falls into the hole, but just can't perceive that it has. We detect black holes because they emit x-rays, have accretion discs, and have a very strong gravitational field. green concept technologyWeb14 mrt. 2024 · The theoretical density of a black hole depends on how big it is and how you define its size. The density at the center of a black hole is infinite (it's a famous "singularity" [1], which leads to difficulties in modern cosmology).
