Magazines where you build something over time

How many do you want?

 

And capable of time travel.

 

I used to sell those

 

Interesting concept . I'm fixed in the here and now and time flows past me.

It's better to work on that basis otherwise you might start to experiment and could be caught in an ontological paradox.

You could try reading Heinlein's 'By His Bootstraps' or Asimov's 'The End Of Eternity'.

Or ask @Zigs for a trip in the GC Time Helicopter.

 

As I don't trust the deliveries from overseas with all these airline strikes I shall be popping over to the Cayman Islands to pick them up once I've received all the deposits. So there may be a little delay.

 

The interpretation of now is too subjective to be every moment of the past and future. The now is subjective time whereas the past and future may be objective observations of possible pasts and futures. Particularly if you subscribe to multiverse theory or infinite dimensional Hilbert space.

The here and now is the construct of the mind so that we can interpret the observable world around us - although your world may be different from mine .

So, if we look at the clock on the wall we interpret the time it's showing as the 'now' time although we know it can't be. What we see is the time recorded by the clock when the light waves we are viewing left the clock and not the time when we receive the light.

It's much easier on the brain to think of it in the macro world of particle physics. When we see, in a telescope, a distant nebula exploding we know that what we are seeing occurred hundreds of thousands or millions or billions of years ago but the light has just reached us. So what we are observing is not 'now'. We are viewing the past but are not in it.

I know some people who are living in the past

Then we have the old theory and arguments of whether, if you had a time machine, what would happen to you if you went back in time and killed your grandfather when he was a child. It's possible in a multiverse but not in a straight timeline.

Then, of course, you have all the religious theories. The short story by Arthur C Clarke 'The Nine Billion Names Of God' was an interesting concept which mixed religion and the use of computers.
