Wormhole 'no use' for time travel

By Paul Rincon

For budding time travellers, the future (or should that be the past?) is starting to look bleak.

Hypothetical tunnels called wormholes once looked like the best bet for constructing a real time machine.

These cosmic shortcuts, which link one point in the Universe to another, are favoured by science fiction writers as a means both of explaining time travel and of circumventing the limitations imposed by the speed of light.

The concept of wormholes will be familiar to anyone who has watched the TV programmes Farscape, Stargate SG1 and Star Trek: Deep Space Nine.

1. That explains why no future peeps have visited us.

2. How would we know?

I mean, other than the odd out-of-place blue police call box inside the loo.

6. Certainly the Infinite Improbability Drive is more feasible.

If you pass through every possible point in the universe at the same time, the concept of travel is moot.

9. That's just what the time-travelers WANT us to think

Obviously, they're using wormholes to go back in time and write articles saying that time-travel using wormholes is impossible. That way, they can stop time-travel from ever being invented... but... but... but then how would they go back in time to... I mean...

<poof>

10. The first object through a Time Machine will be a bomb

Think about this:

Let's say you invent a time machine.
(You invent a time machine).

Thanks.

Anyway, from then on, people can travel back and forth through time using your time portal for all eternity.

HOWEVER, eventually Someone, Somewhere, SomeWHEN will want to destroy it and prevent it from ever being invented.

Given a near infinite amount of time in the future-- let's say 12 Billion years..
(12 Billion Years)

Someone will EVENTUALLY succeed and send a bomb back through the time machine and kill the inventor the moment it is first activated.
