Strangely enough, the simplest example of energy with repulsive gravity involves Einstein's nemesis, quantum mechanics, which holds that even a perfect vacuum is not empty.
Physicists struggled to ditch the ether and accept the void — until quantum theory refilled the vacuum with unimaginable energy, says Paul Davies
Quantum mechanics tells us that the vacuum of space - time is teeming with random quantum fluctuations, which create waves of energy.
This might have practical implications in quantum computing, as ours is a world of constant fluctuation — even a vacuum is alive with vibrations of energy.
Based on particle physics alone, if we were to naively guess what the energy density of the vacuum ought to be, you might think it was zero; and zero was sort of acceptable to us for a long time, but the quantum vacuum that physicists really know is not empty, so, zero was not really a very sensible answer anyway.
And empty space, as you know it, is not really empty, here is a quote about it: The physical interpretation of the cosmological constant as vacuum energy density is supported by the existence of the «zero point» energy predicted by quantum mechanics.
