![]() How small is a gravitational singularity? While it is said to be a point of zero dimensions, our current physical theories suggest that the smallest known scale for space-time is a Planck length, beyond which our physical theories break down and don’t make sense. 2: How small is a black hole singularity?īlack hole singularities are zero-dimensional – The singularity at the core of a black hole may shrink to a size smaller than an atom, with its gravitational force so strong that it forces the spacetime surrounding it to be bent to infinite curvature. A black hole refers to the region in space in which the singularity’s gravitational force is so strong that not even light can escape its pull. Such a star may become a white dwarf or a neutron star, but if the star is sufficiently massive then it may continue shrinking eventually to the size of a tiny atom, known as a gravitational singularity. The closest black hole is 1,600 light-years awayĪ massive star collapsing in upon itself – A black hole is formed when a large star starts running out of fuel and begins to collapse under its own gravity.Black holes eventually evaporate over time.Wormholes appear similar to black holes.Black hole gravity equal to other same mass objects.Objects falling into a black hole are spaghettified.Objects appear to slow down near a black hole.Black holes distort space and slow time.Black hole singularities are zero-dimensional.Caused by a massive star collapsing in upon itself.There is a super massive black hole at the centre of the Milky Way (our) galaxy.For instance a black hole can bend light from stars behind them because of the curvature of space and to an observer (you and me) of that star, it (the star) can appear to be in a different place than it is. X-ray telescopes can see them though, and we can observe the effect of their huge gravitational distortion on objects in the vicinity of the black hole. That's why we can't see them directly - they’re not reflecting any light. We can't see a black hole - the escape velocity required to leave a black hole once you’ve "passed the event horizon” (that’s the technical term for “falling in to a black hole”) is so great that even light can't get out (so you’ll never get out). ![]() Super Massive (millions or billions times as weighty as the Sun).Stellar (a few dozen times as weighty as the Sun). ![]()
