ELI5: What is unified field theory?
gpt
At rediculously seriously high temperature, like big bang temps, the forces we know of (magnetism, strong nuclear, weak nuclear, ECT) "melt".

They melt, and turn into the same force one by one. We know they all do, except for gravitation. We can't fully be sure if that one will also. But since physics likes the simplest most elegant answer, it's likely true that gravitation will also "melt" into the others.

This means that all forces are the same, they are just "frozen" into acting differently, like ice, water, and steam.
