Re: Space-Time, mathematics and physics


Yes, indeed!
Whatsoever, there is no dilemma at all, for the simple reason that, you do
have, first of all, just to see how the equation itself does works.

However, just by the way to see, that along the mass and energy, it would
happen to be a created a curvature along the geometry of space, as a
definitely would change along a flow rate of a time, as along that matter
all the empty universe would a definitely be a flat matter, when it would
contain no stars, no planets as no atoms along the matter all along, then
how would the space be curved as what it would curves any space, and that
would be the ultimate question.

Therefore, it is already known, what the mentioned equation does, as it is
already called, for instance, an empty universe, which it does makes it,
along three dimensions of a space and one of a time, whether it would be
seen as an approach, when you would miss one along the dimensions of a space
and make it as a just would be two dimensions of space at a definitely any
moment of a time, but a definitely not a necessarily a flat matter, as it
is, a simply as that, and that is what is all about, a definitely as a
matter a fact.

Hello.

In my post "are the space-time continuous or discrete", some members
have misunderstood my request for clarifications, in particular the
person who commented "he dont even grasp tha notion of continuous and
discrete". My MSc in Mathematics is 20 years old, so I forgot a lot
but I certainly did not forget what these two concepts mean. I did not
join this forum to be insulted, but rather to seek clarifications
about what the Space Dimension is *physically*, and what the Time
dimension is *physically*. I wish physical explanations, not
mathematical formulas (unless you are sure that they can lead me to
answers).

One member referred to the formula:
r = ct
(in the case of radiation which travels at the speed of light, if I
infer correctly from the formula.)
to show me that if "t", in Time dimension, is continuous, then so is
"r", in Space dimension. Similarly, if "t", in Time dimension, is
discrete, then so is "r", in Space dimension.

That is clear. I have no objection. I understand that.

But the set of coordinates (r, t) represent a *trajectory* of some
radiation (or whatever it is) in the Space-Time dimensions. In the
case of particules, I deducted by myself that their trajectory is
discrete. So then this formula reflects a discrete function,
suggesting that Space and Time dimensions are discrete. Again that
formula expresses the trajectory of a particle, or radiation, or
whatever. The formula does *not* imply anything about the *nature* of
the Time and Space dimensions. If the trajectory is discrete, does
that imply that the dimensions are discrete too? That is my big
question to you all, and the answer does not seem so immediate.

I have to admit that a continuous dimension appears to be an
impossibility in the physical world, if we assume the definition of
continuity from mathematics. So this suggests that all dimensions are
discrete. But philosophically, I find this extremely difficult to
grasp.

Maybe we should not view particles travelling in Space-Time, but
rather view something less tangible like energy, waves... travelling
in space? If we refer to particles jumping around in discrete steps,
then it appears impossible to avoid the question of what is in between
those steps? This is my dilemma.

If anyone can help me, I would be grateful. I know that it would help
if I knew more about physics. All I learned in college is one course,
the classical Newton's mechanics. Is it at all possible to make me
understand without me having to take a BSc in Physics? I'm too busy to
take courses toward a BSc.

Thank you.
