Classroom Aid - Space-Time Minkowski Space xx

[MrFefefofo]

I can select two point inside the given cone on the animation that are timelike or spacelike.
To explain this with cones can be done if the cone set to the first event....

Ironically Minkowski was Einsteins mathematics lecture and as Einstein had bad attendance at Minkowski s lecture he called him a lazy dog.

That was great David, informative as always. Thanks

Proper Time = Local Time but it assumes all others are moving and it is stationary but what if we looked at a number of clocks in various reference frames and discovered they are all running at different rates? Wouldn't that be proof that there is a spacetime reference frame (effected by GR so it's not flat) and objective proof that this assumption (all others are moving) is wrong ? After all this Proper Time is only based on the simple assumption that the closing velocity or opening velocity is the other object's movement and not your's ? It also assumes vector velocity as objective and not subjective velocity. We know through experimental data that clocks compaired before and after acceleration are rock solid proof that time dilation is a product of velocity (with one hypothetical exception that I believe is key). Given my input the math is correct even though it gives no evidence if xt or x't' is the one experiencing dilation only assuming x't' is actually the one with vector velocity. At best we can only assume this is a differential equation but like with special relativity without outside data there is no way to tell which Reference Frame is "correct", however if in reality we could look at these clocks the one running slower is more correct, the problem with Minkowski is it's a limited model assuming one space dimension which would actually correlate to a vector speed compaired to another vector speed (if xt and x't' are both moving). Someone please tell me I'm not wasting this insight on "math majors" who lack imagination and those who are awed but don't have a clue.

Excellent. Very helpful, very clear.

That is the hyperboloid and torus of Aether.
A Scalable Aether, Casimir Effect Universe. Space and Counterspace are the plates. The Inertial plane attracts and repels the plates.
e- >~< p+ = Aether's Hyperboloid. Aether's Torus is Magnetism. Magnetism gives Magnitude to the Universe.
1836 p+ in Counterspace = 1 Proton, as seen from Space.

2:37 That lenth being zero makes no visual sense to me... I wonder if there is a better visualisation of Minkowski Space that shows zero lenth lines being... Zero lenth on the screen as they should...

OK but if there are 2 events in the future light cone - A and B and the line that connects them could be crossing the vertical axis at angle >45°. Does that mean that every point inside the cone has its own cone with time axis different than the bigger cone that includes them?

Just like the New Hampshire farmer trying to give directions to the ‘city-slicker’ on how to get to White Water Junction finally scratches his head and says, “Ya`can’t git thar from here.”

[MrFefefofo]

Spacelike or timelike do not do anything with the cone. to be inside or outside. as here in the animation,

It does if the cone is set tot he first event, !!!! But here in the animation the cone stays and have not set to X1.y1, z1, t1

I'm not clear as to what the 'negative light line' represents. I'm seeing the right light line representative of the speed of light.

[shrodindsy]

how can I plan can be used to represent 3 spacial dimensions ?

[dadsonworldwide]

I've been reading direct works by enstien and its like a different person than taught to me. So many edited quotes. I'm not so sure he ever held to this adaptation it does seem like he kept to variable speed of light.
Get outside our solar system and this tool we created is more apparent than we think of teach it to be. On the small scale it happens also.

What are people's thoughts on the giant Van Der waals theory, that is to say that all movement of matter with mass causes spooky action from a distance, would that action cause effects instantly i.e faster than the speed of light.

[dathnsuranc]

for the space plane, can it be visualized as a cube? so that it encloses the light cone? or is z always 0 since it's just a plane and just 2 dimensional.

[sotogremble]

What does light moving in the negative direction mean?

[BurevestnikM]

Why do we have time here at all? Time does not exist. Instead, we should start from the d-v diagram (distance-velocity)

[mravouvacar]

im now confused, timelike s, is it not negative ????

[maheshudupa]

How is the metric 0, if the line runs through the edge of the cone? Even if it's a convention, why this specific convention? TIA!

[MMaRsu]

I was looking for information if its possible to fold spacetime but I cant really find anything on it :(
