>dark energyA force that exists everywhere and constantly pushes matter apart unless bound by gravity. It's the reason why there's a hard limit of what part of the universe we can explore and what will forever be out of reach.
Dark energy is likely related to quantum fluctuations which cause a gravitational effects (yes, gravitational pull from nothingness) though the one time someone tried to calculate how big this effect would be mathematically, he ended up with a value so high (worst prediction in the history of physics) that it would've ripped our universe apart nanoseconds after it was born. So there must be some kind of negating effect that cancels out the gravitational pull from the quantum fluctuations.
