Answers: How large can black holes get in the universe?

• Primordial black holes
• Stellar black holes
• Supermassive black holes
• Ultramassive black holes
• Black hole growth and mass comparison

What it concludes

• Primordial black holes may be the oldest objects in the universe, potentially formed shortly after the Big Bang.
• Stellar black holes are formed by the collapse of massive stars or mergers like supernovae and kilonovae.
• Supermassive black holes sit at the centers of most galaxies and are held together by dark matter rather than gravity alone.
• Ultramassive black holes represent the largest single bodies in existence, growing up to tens of billions of solar masses.
