Because of your high level of stupidity, I will show a little more
patience with your ignorance. Above, you believe that s-t is "of this
world", a real place and not a fictional math construct as everyone
else knows. You're all alone out on that limb, idiot. How does it
feel to be the only one in the world to believe in something no one
else believes?

The only way you can argue your stupid belief is by using childish
tactics in attacking your tormentors. You have gone to great lengths
to set up and maintain your websites just because you have nothing that
makes sense with which to argue.


To whom are you addressing TomGee?

indicates the object's past, current, and future position wrt its
motion through the universe.


Unroll a paper tape as you walk and mark it every 10 seconds as it
unwinds. Congratulations. You just make a world line. No math construct
there, Tom.

I'm in a room that is 10' by 12' by 14'. Is the central 2'x3'x5' block
of space a math construct or is it really there?


AE invented a universe having the same exact dimensions which our own
universe contains, i.e., length, width, depth, and time. He did it to
show that he was not talking about our universe but an imaginary one.
His lemmings, however, insist he was talking about a real place and
they talk about it as if it exists. Go figure.

What exactly is space time ?

A four dimensional metric space of indefinite signature.

Why cant we travell through the 4th dimention (time axis)?

We can and we do. The rotating second hand on my watch is a clear
indication of this. Time on this level seems to have a directional
arrow associated with it, but that is a thermodynamic consequence
corresponding to increasing entropy. On a fundamental level, most laws
of physics don't care which direction time goes.

Time does not change. Time is an abstract parameter used to denote
change in physics.


Only in Newtonian physics. In relativity time is a coordinate.


Funny, but I doubt that nature gives a rat's ass which physics you
use.

To describe a change in time would require a
meta-time, and a meta-meta-time for the meta-time, ad infinitum.


Wrong. All changes in spacetime in relativity are compared to
invariant proper time intervals along the worldline. Coordinate time
and proper time are two entirely different things.


Certainly. Proper time is measured in seconds, as it should. But a
coordinate is measured in meters, right?


Wrong again. Coordinates can have any units you choose to give them.
You must have been absent that day!

Remember ct? Now the meter is
a unit of what, again? ct is measured in what, again?


Furlongs!



Nasty Little Truth About Spacetime Physics:
http://www.rebelscience.org/Crackpots/notorious.htm

Don't let the morons in the physics community fool you, especially the
idiots, Dick van de merde and Sam Wormley. ahahaha... ahahaha...



What are you jealous that they are truly educated in this area and seem
to know what the hell they're talking about?


Jealous, your ass. Wormley and van de merde still can't figure out
that nothing can move in spacetime. But then again, neither can you.
You are all a bunch of ****ing idiots. Not to mention ass kissers.
ahahaha... ahahaha...

And one more thing, before I forget. I got your education hanging,
right here. ahahaha...


Still jealous. Well, out of ignorance comes frustration, so I can
understand your situation. You periodically peek out from under your
own self-imposed rock to see what is going on in the real world. It's
never too late to really learn this stuff you know. If you need to
critique physics, it would help to have a knowledge of the subject.
Otherwise you will perpetually come off looking like a complete ass and
you'll always remain what you are right now -- a pathetic little usenet
punk who was never able to grasp even the basics. It's up to you.

Ah yes...
Measuring distances and times and using them to calculate
where and when the impact of the cannon ball will take place...
ah well, it's just "not of this world":

Brilliant point of view.


hey clown, I think I saw you in the circus taking off from inside the
canon and in the way you were screaming proper time is invariant but
you could only measure coordinate time so you ended up with the severe
head damage you have.

How stupid is it when you think that is a world line? How stupid is it
when you don't even know what a math construct is?

It's a shame that such a high-rated physicist (as you rate yourself)
has no clue as to what constitutes a math construct. Somewhere along
your educational trail someone must have explained to you the
limitations of mathematics in relation to conclusions about reality.

If one wants to be pedantic about it, you are of course correct.
The worldline of a moving point particle is a curved line in a
4-dimensional continuum -- which we cannot visualize except through
various means such as taking 3-dimensional slices thereof.

(The line is curved if there is mass in the vicinity warping things.)

The worldline of a *stationary* point partidle is also a line; there's
some issues as to whether anything really can be stationary in light
of the absence of any real absolute origin.

I'm sitting in my chair. Relative to the Earth's center I am
moving along a latitude line of about 37° 22', giving me a
velocity component relative to the Earth's mass-center of
about 368.6 m/s. The Earth's motion around the Sun is
about 29800 m/s. The Sun's motion around the Galaxy is
unclear, with quite a bit of wobble. The Galactic Core is
probably moving as well relative to -- something.

What is my timespace worldline doing, really? :-)
