The universe may contain a staggering 40 quintillion black holes
Astronomers estimate that about 40 quintillion stellar-mass black holes exist within the observable universe, a number written as…
The universe’s total mass-energy budget, according to standard cosmology: 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy — meaning everything made from the atoms on the periodic table accounts for less than one-twentieth of the cosmos.
Everything directly available to our senses belongs to the smallest slice of the standard cosmological budget. Stars, planets,…
