Is the concept of infinity practical or just theoretical?
In: Mathematics
The vacuum of space is the only infinity that exists in every direction. Otherwise, everything else is finite: the number of atoms in a galaxy, the rate of conversion from mass to energy, the number of photons emitted by phosphorescent sources, the paths of those photons and other particles, the timing of their release from an electron or neutron, the extent of the observable universe, the mass of black holes, etc.
Infinity is a mathematical abstraction that helps our equations in determining probabilities, but doesn’t adequately describe the universe as a real object.
