  1. just for the sake of sharing, one way i managed to get my head around "space/time" was when i realised light not only travels at the speed of light always, but it always travels in straight lines - always. when we say light is bent by the gravity of the sun or galactic lensing, what is happening is that light is STILL traveling in a straight line, but that space and time itself are being bent and the ray of light is still travelling "straight" through it.

  2. 1:35:00 surely we'll know when AI becomes actual AI cos it will be drumming it's fingers waiting for you to come into work on monday cos it's done your job over the weekend and wants to prompt YOU with questions.

  3. 1:28:00 i thought that penrose and hawking, who proposed the singularity idea had dropped it before hawking died?

  4. 1:32:00 i was listening to antonio padilla on sean's show, the episode called "big numbers" and he suggested that the universe is so big that if you were to travel far enough you would encounter another milky way, almost, if not totally, identical to our own - no need for parallel universes or "many worlds" scenarios, just the universe is so big everything and anything is possible just by chance. when it comes to simulation one thing in it's favour is that when you run psychological experiments on people generally they have no idea what exactly is being tested or why - and that kinda describes the universe with live in, what the heck is it all about. another reason god is unlikely, if god wants us acting sincerely, we would surely have no clue a god existed. and i think one thing that points to this not being a simulation, that also points to it not being a god creation is - the higgs boson, the simulations we run don't need that much detail - i have to ask why would god, or the guy with the clip board who designed this simulation, require the higgs field? there is too much unnecessary detail in this universe for either a simulation or god to have done it. unless it's like the movie "predestination" where ethan hawke is the time traveler, his mother AND his father - life created itself in some kind of penrose cyclic universes.
