I hereby launch a conspiracy theory into the wild.
Respected theoretical physicist Stephen Hawking has a degenerative muscle disease that means he communicates with the aid of a machine.
In recent weeks Hawking has made two slightly controversial claims – claims that if not made by a respected theoretical physicist would be laughed off as science fiction. Firstly, he claimed that we shouldn’t seek aliens out because they’re unlikely to be friendly. Secondly, he suggested that time travel is possible under certain parameters.
I think that it is plausible that some science fiction geeks have hacked into Hawking’s computerised voice box forcing him to make such outlandish claims.
