Professor: Advanced physics tells us that no light from outside the Hubble Limit can ever reach us!

Professor: Inside of the Hubble Limit, we dolphins are the only known form of intelligent life!

Student: But Professor, sir, isn't it possible that beyond the Hubble Limit, there are other intelligent creatures?

Student: And one of them is imagining what we look like and even drawing pictures of us??!

Professor: Young man, it makes no sense to even imagine that! We can never know because nothing will ever go faster than light!

Professor: Not even neutrinos!
