Erm… excuse me, this is total bollocks, isn't it?

BBC: New model 'permits time travel'

If you went back in time and met your teenage parents, you could not split them up and prevent your birth—even if you wanted to, a new quantum model has stated.

Researchers speculate that time travel can occur within a kind of feedback loop where backwards movement is possible, but only in a way that is "complementary" to the present.

In other words, you can pop back in time and have a look around, but you cannot do anything that will alter the present you left behind.

Hands up who thinks this explains anything.

The present you leave behind includes a (continuous) past where you didn't go back in time. So, as of, say, a week last Thursday, you had never gone back in time. So how come this past that you go back to doesn't have to be "complementary" with a week last Thursday too? But, to be complimentary with a week last Thursday's history, you can't have gone back in time… HANG ON, WHY AM I EVEN DISCUSSING THIS NONSENSE?

Of course, we know the real reason why the BBC chose to publish this silly story today: it's the end-of-series, Dalek™-laden grand finale of Dr Who tomorrow.

Can't wait! See you behind the sofa!

  1. Surely travelling back in time would be destructive to the present. I believe* once you embark on a journey to the past you travel sideways into parallel timestreams(tm)** so it's future is no longer your there fore permitting you to kill your parents and live.

    I thought the last Dalek had been killed.

    * Operative word.
    ** My invention, just now. Clever huh?

  2. Yes, I have no great problem with the idea of parallel timestreamsother than the whole idea is pretty unfalsifiable at present.

    Don't you believe it about the Daleks there are apparently thousands in the series finale.
