Imagine the letter "s" to be squares.
- S S
S S S S
- S S
Now the trick is to arrange the numbers 1-8 so that no consecutive numbers touch, either next to each other or corners. Oh and its not a homework assisgnment. Pay no attention to the "-" I just needed a place holder so that the letter s would be arranged to fit the problem.

For example, they say we would never be able to live long enough to travel to the nearest star, because it's 2 light years away. But the astronauts only had 1 day of beard growth on there face in 5 days time because of E=MC2, time for them was slower because they were travelling faster. So if you're travelling fast through space, it may take you millions of Earth years, but only 2 space years, right? If I'm wrong then I guess I just proved Einstein wrong.
