Organizer’s question #1
How come I can move around in any direction of space, but time marches forward no matter what I do?

How about, no, you can’t move around in any direction of space. You are limited by the curvature of space-time. That is, gravity. You can’t jump up higher than a few feet. Okay, you can get a rocket and leave the Earth. But try to move in space just one feet above the surface of the sun for a while. Okay, get a real big rocket that an escape the sun. Now fly into a black hole and move yourself in the direction “out of the black hole”.

How about you can’t move around in any direction of space. You are limited to only one direction. You can move forward or backward or up or down or left or right. In any given movement there are five directions it will be physically impossible for you to move in, because you are moving in one of them.

How about you can only move in one direction of space - forward. As time moves, space moves. Say you are at the NW corner of 5th and Arch. Now you cross the street to the NE corner. Can you move back to the NW corner? Yes. But if your NW starting point, you named before leaving, “point zero”, can you get to that point again? When you return to NW, you think that you are back in the same place because you are kind of trapped in a relativistic view of space and time. But the Earth has been spinning at 1000 miles an hour. The earth is moving 67,000 miles an hour relative to the Sun. The Sun is rotating around in a galaxy, which is one of billions(?) of galaxies that are all speeding away from each other in a Universe that is not only expanding, but the speed of expansion is increasing.

There is not one single point of space in the universe where that place in the universe can be returned to unless you define a space as being relative to some other moving point in space. It is as gone as yesterday is. You can only leave point zero and go to point one and then “return” to point zero-prime. Zero-prime being a place that looks very similar to the same zero point in space on a superficial level relative to another place that has also moved, to position one-prime. Zero is gone. You can really never go there again for the rest of your life. Just like time.

You are trapped in constant movement, not free to stay immobile in one spot. Always you are moving in a direction in space, one that it also, apparently, related to entropic theories of the expansion of all things in space into dust eventually.

But the little goggles and brain you have are tricking you into thinking that you have either remained motionless, or returned to the same position place you were before. A trick of the brain.

So, space AND time both are “marching forward”. You live in an illusion that space does not march forward because you measure it relative to other forward-marching space. Are we doing the same thing with time? Is time really “marching forward” independently of space?
