Right. If I'm observing a slice of spacetime (a "flipbook frame" as I sometimes call it, or "atoms of spacetime" as loop quantum gravity calls it), then what I am seeing in the sky is not part of that slice - because the further away a star is, the further in the past I'm viewing it.I talk about this in vlog entries like "The Flipbook Universe" watch?v=Rc_VliIuPhQWormholeswatch?v=mi2Nh_C8PzkWhat Would a Linelander Really See?watch?v=T9_-ZOIES0Uand Scrambled Eggswatch?v=CFZVd_Ez23g

Hes slicing spacetime at an angle to create simultaneity. But that simultaneity is not perceptible in the 4th dim as it would take a sec to confirm B,s death on the video camera which is also limited by C. But if we imagine a higher 5th dimension its easy visualize simultaneity as a simple line drawn from one point on persons 4th dim time "smear" to another arbitrary point on Bs time smear.

holy shit this makes soo much sense and i am not even kidding !

This is incredible work. Great videos.

The idea of time being a direction rather than a dimension is discussed in vlogs like "Time is a Direction": watch?v=LDajcGcKiAM"Why Do We Need More Than 3 Dimensions": watch?v=kzlRuygMGHYand "What Would a Linelander Really See":watch?v=T9_-ZOIES0UThanks for writing!Rob

Anton Zeilinger at the University of Vienna has now conducted experiments showing how local realism is violated. Deutsch's team at Oxford published a proof equating the quantum probability waves with the parallel universes resulting from chance and choice at the macro level. These and many more facts confirm again and again that this way of visualizing reality, where the fifth dimension appears to be "curled up at the planck length" because of the way we're viewing it, is worth considering.

Generally speaking, physics completely allows for time reversal symmetry - the universe makes just as much sense in the reverse direction as it does in the forward direction. This project says time is a direction, not a dimension, and you need to consider both time and "anti-time" to consider it a dimension. Quantum physics has now shown evidence of reverse causality(see the work of Lev Valdman at Tel Aviv University), and loop quantum gravity says our universe comes from "atoms of spacetime".

These are simple theories created by humans that serve to explain the way things are by offering explainations that make the most sense to the majority of humans based on previous experiences and lessons taught by other humans. Nothing more than words with human-instilled meaning behind them that is not likely to accomplish anything until the theories are proven. Stop debating previous theories that you learned in multiple videos/classes that may clash with theories that someone has learned.

I don't know if you have already addressed this questions but how can time exist as the 4th dimension if you show time to exist in the second independent of the third? I think time is more of something which analyzes proximity than a perpendicular extension to 3 space.

Part II:Also there is the problem of viewing the entirety of space-time as a series of "snapshot" moments. This viewpoint was inherent to some of the later higher dimensional analogies. The problem is that Capital-R Relativity forbids this due to the elimination of simultaneity caused by the speed of light being a constant. (Different observers will observe different times for a supposedly "simultaneous" event - this means no snapshot or "universe-moment" is possible.) |
