then all energy in the universe has always existed... there was no beginning..
I don't think so. Conservation only applies to closed systems. Unless the universe stops exanding, we can't assume it's closed.
i dont really comprehend how energy was somehow created from nothing at the beginning..
Don't worry, nobody else understands that either. :rofl:
In quantum physics, there are loopholes to conservation laws. You can 'borrow' a little energy for a short amount of time, as long as you pay it back later.
