Firstly, I assume that I'm correct in assuming that since expansion is accelerating it will increase to any arbitrarily large value at some point in the future. If this is true, there must be some point at which particle/antiparticle pairs (due to uncertainty) are carried away from one another at greater than the speed of light, analogous to the way in which hawking radiation is created at a BH's event horizon. Is there anything wrong with this thought experiment?(adsbygoogle = window.adsbygoogle || []).push({});
