Is there a limit to how big a black hole can get?

There is no theoretical upper limit to the mass of a black hole. However, astronomers have noted that the ultra-massive black holes (UMBHs) found in the cores of some galaxies never seem to exceed about 10 billion solar masses.

How small can a black hole get?

NASA scientists have identified the lightest black hole yet, just 3.8 times the mass of the sun, in a binary star system in the Milky Way known as XTE J1650-500. The next smallest black hole, spotted in 1994, weighed in at 6.3 solar masses.

Is there a maximum mass?

The Chandrasekhar limit (/tʃʌndrəˈseɪkər/) is the maximum mass of a stable white dwarf star. The currently accepted value of the Chandrasekhar limit is about 1.4 M ☉ (2.765×1030 kg). Those with masses up to the limit remain stable as white dwarfs. The limit was named after Subrahmanyan Chandrasekhar.

Is there anything bigger than a black hole?

There are things out there bigger than even supermassive black holes. Galaxies are collections of star systems and everything that is inside those systems (such as planets, stars, asteroids, comets, dwarf planets, gas, dust and more). Nebulas, or vast clouds of gas, also have impressively large sizes.

Does mass really increase with speed?

The mass of an object does not change with speed; it changes only if we cut off or add a piece to the object. Since mass doesn’t change, when the kinetic energy of an object changes, its speed must be changing. Special Relativity (one of Einstein’s 1905 theories) deals with faster-moving objects.

Why is there an upper limit to the mass of a white dwarf?

5) Why is there an upper limit to the mass of a white dwarf? A) White dwarfs come only from stars smaller than 1.4 solar masses. Near 1.4 solar masses, the speeds of the electrons approach the speed of light, so more mass cannot be added without breaking the degeneracy pressure.
