Have aliens hijacked Voyager 2 spacecraft

Wrong.

The other day I had a stomach cramp, fast as LIGHTNING I rushed to the loo, switched the LIGHT on, and...

diarrhea had been faster.

Theoretically speaking... If you were travelling at the speed of light, and then pointed your poo hole in the direction you were travelling and let rip... How could your poo be doing anything other than travelling faster than the speed of light?

Or would it just be a turtle head forever if nothing can indeed go faster than light?

Now these are the important questions!

Hawking covered this in episode 2 and used the ultra fast future-train analogy. You simply would not travel faster than the speed of light because once you approach light speed the fabric of space and time would change now if time no longer applies to the observable surroundings then s=d/t doesn't apply any more surely! Nature just doesn't allow it going by Hawking's (and Einstein) thinking.

You would always be travelling at close to the speed of light, not faster than it. And the closer you are to light speed and the closer you travel to an object with massive mavity (Black hole for example) the slower time will get around you. So if a ship was made that could orbit the Sun at near light speed or anything else with a massive gravitation pull then by the time you left orbit you'd be in the future by how ever many years depending on the orbit etc.

He also goes on to say because of this it would most likely not be possible to ever go back into the past so time travel would always be a one way journey and only into the future.

Agreed with everything except the last bit.

My father travels so infinitely slow when it comes to fashion, that he's still in 1982. Ha!

So the poo couldn't come out? So you'd have a turtle head, and time travel? Whoah!!!!!
