One of the talks here at LCA involved concurrent algorithms for high-speed trading.  Which led to the question of how to reduce instability from high-speed trading.  Which led to the idea of placing the exchange on Mars, relying on Earth-to-Mars speed-of-light delays to calm things down.  Which has substantial scientific benefits:  The traders would of course want to place their computers near the exchange, which would put some serious money behind travel to Mars.  Which would of course eventually defeat the purpose of placing the exchange on Mars, but life is like that sometimes.  Besides, wouldn't it be cool to see a group of rovers chasing each other across Mars, jockeying for the best positioning to reduce speed-of-light delays?

Maybe we should send the traders to mars, and leave the rest of the stuff (include O2) here?
 
Place the exchange on an object that is continously accellerating away from earth. We'll invent near-light speed travel real fast. :-)
 
Firstly, humans behaving like paniced sheep causes far more instability than algorithmic trading. 

Secondly, if you wished to level the technology playing field on HFT, there are trivially simple ways to do it without sending anything to Mars ;-)
 
Seriously, the fundamental problem is, humans are free to build private exchanges, and traders will gravitate towards the most liquid ones.

Putting the most popular exchanges on Mars or delaying them on our planet will only increase the popularity and size of the current secondary and tertiary markets.

This kind of efficiency based liquidity shifting is happening all the time between and within exchanges already, as traders migrate to better markets and migrate between overlapping instruments, products.
 
+Martin Bligh True, but people would rather blame others for their panicked-sheep behavior.  ;-)
 
People wishing to slow down trading always remind me of the red flag act of 1865 - requiring a man on foot to walk in front of any horseless carriage waving a red flag, because they go too fast. Damned newfangled nonsense.

Whilst we're at it, that electricity thing is a damned nuisance, someone will get killed playing with that stuff. 
 
+Martin Bligh Nah, we cannot get rid of electricity!  That would also get rid of computers, and I don't believe I could handle the withdrawal symptoms!
