Hi

Two more interesting Einstein quotes to have a look into Einstein's mind: << From a "happening" in three-dimensional space, physics becomes, as it were, an "existence" in the four-dimensional "world". >> (Albert Einstein. "Relativity: The Special and the General Theory." 1916...

He wrote: <<...for us convinced physicists the distinction between past, present, and future is only an illusion, although a persistent one." >> ( Letter to Michele Besso family, March 21, 1955. Einstein Archives 7-245).

A few Einstein quotes might help you: << Since there exists in this four dimensional structure [space-time] no longer any sections which represent "now" objectively, the concepts of happening and becoming are indeed not completely suspended, but yet complicated. It appears therefore more...

Grimble, let me visualize this for you. (I use a Loedel diagram. A Loedel diagram uses same unit lengths for both reference frames (Minkowski diagram doesn't), which makes it easier to understand that the 'time dilation' is actually not due to a stretching of reference units... or worse, a...

- That's even worse. I thought the goal of communication in science was to be as specific as possible? The 'projection' and 'shadow' wording follows from looking at a stick from a non-90 degree angle, resulting in a shorter view of the stick. This misleading analogy blocks the interested...

I don't understand your 'shadow'. 4D world contains far more events than one 3D world. Hence a 3D world cannot be a projection nor shadow of such a vast 4D world. A 3D world is a section through 4D world.

Yes indeed. Einstein himself considered it a Block. Some Einstein quotes will help you: << From a "happening" in three-dimensional space, physics becomes, as it were, an "existence" in the four-dimensional "world". >> << Since there exists in this four dimensional structure [space-time] no...

There's also the Block Universe interpretation: The physical phenomenon is not that one looks at a physical 3D object from a different point of view, but rather that one observes a different cut through a physical 4D 'spacetime' object. (To follow your circle/ellips comparison: the ellips is...

The event is not coordinates. The event is: car hits tree. Hence it contains car and tree.

All I can say about this article is that it doesn't give any insight al all. Nobody fully understands what you write there. As far as I can remember -correct me if I'm wrong- there was a forum thread where the article was also discussed, you participated, but you didn't like what was being said...

It might be interisting for the forum readers. As far as I can remember you call 'physical' only what is measured. But this means one is not allowed to talk about a 3D universe of simultaneous events occurring now. Which means we are not allowed to make a 3D cut though the apex of the lightcone...

I never said that. How can you pretend this after reading what I said about Ibix post? see #142 No. You didn't understand me. I'm talking of 3D worlds or 3D universe 'now' as 3D sections made of simultaeous events. What's you point of view on Ibix post #127 ?

Looks fine to me. Great. No 3D world is physical? If the physical world is 4D, then 3D as a part of 4D has to be physical too. Yes, and I gave up because we couldn't get on the same wavelength. Maybe we disagree on the meaning of physical. As far as I understand Ibix, the events as such are...
