Theoretical physics + sex = a science lesson that anybody can understand.
Here are two of the Top 10 reasons why sex at the speed of light is not an advisable form of procreation:
7. Relativistic flaming semen:
In the unlikely event that a vaporised penis can perform ejaculation, then the relativistic semen will create enormous air resistance, burst into flames almost instantaneously, and generate enormous impact forces. These forces will be sufficient to pierce a small hole straight through a woman’s lower torso, just like a speeding bullet, only incinerating the surrounding tissue as it passes through.
6. Time-dilated necrophilia:
Unfortunately, the woman will probably be dead before ejaculation anyway. According to the relativistic theory of time dilation, then if the man is to actually thrust in and out at a speed infinitesimally close to the speed of light, then from his point of view, his partner will be ageing extremely quickly, and will be long dead before he ejaculates. Legally, he will be committing necrophilia.

If you have a question about sex and physics. Dr John will answer the question with sex…and physics.
