It is physically impossible for any human to run three hundred miles per hour. We have invented a workaround for that called "the commercial airliner."
It is physically impossible for us to yell loud enough to hold a conversation with someone on the other side of the world. We have invented several workarounds for that, like "the telephone," or "the internet."
It is physically impossible for us to remember every useful piece of information we come across, so we invented a workaround called "writing."
In each of these cases it doesn't matter that we can't do the required physical task, because we have changed things so that the required task isn't nessecary. The original situation is a farce, rediculous to even think about, because we are so good at inventing workarounds.
Eventually, the objection that "we can't travel faster than the speed of light" will be just as rediculous because we will have invented a workaround that makes the whole thing meaningless.

It's called "delta-vee" Jeb, and you're out of it.
