Watch “Why the Universe is quite disappointing really – Episode 6” on YouTube
I had to suspend the production of these videos for a month or so while I dealt with examination matters, but after that short hiatus, here is Episode 6 during which I explain just how weak and feeble the force of gravity really is. Combined with the fact that the Universe has such a low density (see Episode 5), the weakness of gravity means that the cosmos evolves extremely slowly.

And for two electrons, the ratio of electrostatic to gravitational force is ~ 10^{-42}. It’s rumoured that if anyone finds out just why this is the case, the universe will be replaced by something even more disappointing…
