Is Spacetime Flat or Curved ?

[socratus]

Where (and/or when) would you (or anything) be in a non-gravity system?

Perhaps at (or just beyond) the edge of the Universe.
But at that point, what's the point?
O.K. So maybe time doesn't exist outside our universe.
So what?

I think I get it.
You're saying time exist everywhere.
Right?

bi

Time exists only in gravity systems.
For example: we live in Earth gravity-time system.
Depends on gravity-mass and its speed every gravity system
has its own gravity-time.
Without gravity-matter we have system that was called
'' absolute spacetime'' - SRT.
In this system the ''time'' is frozen - no ''time''.

[socratus]

I don't mean time as in days
I mean a time field, maybe call it a spin field, or a movement field.
electricity and magnetism show up at 90 degrees to each other when
something is moving, so the other 90 degrees from each of them
is movement, take the average amount of movement in an area
(usually atoms with internal spin), and that sets the magnitude of this field,
I like time field, one person called it a tempic field, but am up for other names
this other 90 degrees to electric and magnetic fields can be spinning like
in an electric generator, or straight out like with a radio wave at the speed
of light
see what I am getting at now ?

Do you want to say that electricity and magnetism have its/their own time
( a time field ) of existence ?

So when the astronauts were on the moon, they were in different time? Your theory makes no sense. Gravity expands or fills the Universe. You say we're in the Earth gravity system yet are we not in Sol's gravity system, and that of the Milky Way galaxy, and in the galactic cluster? There's no escaping it.

'' absolute spacetime'' - SRT.

My question was: Where, or how, or when can one be "without gravity"?

while sleeping last night I got how to say it (I hope)
if there is an ether, or other fabric everything is made of, knowing how it works is critical. lets go through the various dimensions, for a dimension to be new, it has to be something new. and they are seemingly all at right angles to the previous one.
starting at the first dimension and going up
1. length, it has an orientation and a magnitude (each one of these has its own properties that also includes the previous one)
2. area, this is at a right angle to length
3. volume, this is also at a right angle
so the first 3 takes care of our 3-D space.
4. is movement, at a right angle to our 3-D space, and is typically spin
5. a divergent or convergent spin. this is at a right angle to the spinning field. this is also known as electricity
6. a curl effect of electricity, and everyone gets this one is at 90 degrees as well (think electromagnetic coil), also known as magnetism.

so most people get that dimensions 5 and 6 are field forces, but they forget about dimension 4 being a field force (mostly because it is the same on the surface of the earth pretty much regardless of where you go)
theoretical physicists have predicted dimensions that are wrapped around themselves, but failed to figure out that they discovered magnetism.

clear anything up ?

bi

a) If you live on the planet Mars then you would vive by Mars-time.
b) Gravity cannot cover all Universe because the gravity -matter in the whole
Universe is very few.

c) Quantum ''virtual particles '' can exist without gravity.

Yeah, very clear.
Scientists forgot about 4-D.
Now clearly explain what 4-D is.

Is Spacetime Flat or Curved ?
The term '' absolute spacetime'' came from SRT.
SRT is theory without gravity-masses.
SRT describes physics in the absence of gravity-masses.
That means - the ''absolute spacetime'' ( without gravity-masses ) is flat continuum
and light / light quanta must (!) travel only (!) on straight line (!) and
not ''on geodesics '' / curved line as now some cosmologists think.
===============

[socratus]

'' A world without masses, without electrons, without an
electromagnetic field is an empty world. Such an empty
world is flat. But if masses appear, if charged particles
appear, if an electromagnetic field appears then our world
becomes curved. Its geometry is Riemannian, that is, non- Euclidian.''
/ Book 'Albert Einstein', the page 116, by Leopold Infeld. /
#
Masses (like Sun's) can appear only in local places and therefore
the curvature can appear only in local places.

thought I did already in my previous post

my real point was to say that space and time are not the same
mixing them together makes for bad math

Mathematical definitions of spacetime:
a) Plus 4D is spacetime.
b) Light-cone world is spacetime.
c) Minus 2D (pseudo Euclidian space) is spacetime.

And all these definitions is used to explain the space and time
(spacetime) where light is traveling.
#
Physical definition of spacetime:
the velocity of light in the vacuum (!) is constant and independent of its source,
#
Vacuum (!) is frictionless continuum.
All mathematical definitions of spacetime also must be frictionless continuum.
#
Without unity these definitions the SRT debates have no end.

[spacecase0]

I don't like the mathematical definitions of spacetime, I think they are flawed.
and and in case you had not seen this, relativity has been disproved
THEORY OF RELATIVITY ? UTLIMATE DISPROOF

I am suggesting that we model it another way.
leave 3D space fixed,
and then use the idea of the time filed that sets the speed of light
this leaves you with easy math and shows what gravity is at the same time.
3 space dimentions that do not bend, and a time field. (the time field being related to the electric and magnetic fields)
2 dissimilar time fields causes motion of objects (gravity) between,
this lets the star clusters that we see in the sky be possible,
the spacetime warp thing says that they are not possible, it says they would collapse, and yet they are out there in the sky not collapsing at all

Book: ''What we cannot know'' by Marcus du Sautoy.

'' Gravity is actually the distortion of this space-time surface.
If something has mass, it curves the surface. The classic way to imagine
this is to consider space-time as a two-dimensional surface, and the effect
of mass as that of placing a ball on this surface. The ball pulls the surface
down, creating a well. Gravity can be thought of as the way things get
pulled down into this well.
This distortion of space-time has on interesting effect on light.''

''So in order to find the shortest space-time path. light will
follow a trajectory . . . .''

/page 270 /

'' . . . light would be bent by presence of a large mass.''
''. . . a curved space-time was provided by the British astronomer
Arthur Edington's observations . . .''
'' . . . light from distant stars would be bent by the gravitational
effect of the Sun.''
''The fact that the light did indeed seem to bent round objects of large mass
confirmed that the shortest paths weren't Euclidean straight lines but curved.''

/ page 271 /
===============
It seems that everything is correct.
Author, a British mathematician Marcus du Sautoy,
https://en.wikipedia.org/wiki/Marcus_du_Sautoy
only forgot to say that '' objects of large mass'' (like our Sun) in the
Universe as whole are very few and therefore the gravitations effects
are only local effects. Light is curved only near (!) the '' objects of large mass''
The gravity of our Sun doesn't have influence out of the solar system.
Gravity doesn't work in the Milky Way and therefore was invented so-called
''dark matter'' and ''dark energy'', a new words, a new speculations to prove
that ''gravity'' do indeed is fundamental (not local) effect for all the Universe.

If you see on the gate of lion the inscription ''cat'' . . . would you go inside?
The facts say: the absolute space-time (the Universe as whole) is flat
but modern ''scientific'' inscription is said '' Universe is +/- curved'' or
''spherical'' after '' the big-bang''.

The world began not with a Bang, but with a Black Hole
Scientists challenge the Big Bang Theory of origin of the universe

The world began not with a Bang, but with a Black Hole

===========================
Scientists have come up with a new theory about the origin of the universe,
and it does not involve a Big Bang! Instead, they are saying that the universe
was formed from the black hole of a previous cosmos.

Researchers from the Perimeter Institute have claimed that the Big Bang Theory,
which states that the world burst into existence from a singularity, seems unlikely.
"The big bang hypothesis has our relatively comprehensible, uniform,
and predictable universe arising from the physics-destroying insanity of a singularity
It seems unlikely," they say, as reported by Outer Places.

Instead, according to them, it is more likely that black hole is at the bottom of the matter
as they have the capability of creating as well as destroying celestial bodies, majorly stars.

According to the new theory, our universe has been formed by a fourth-dimensional black hole
that is a part of another universe. In that case, we are living beyond the horizon of the event
and it is also possible that other universes have been created by black holes in the 'parent universe.'

This theory solves the 'information paradox' related to black holes that have been confusing
scientists for many years. It states that all information and physical matter disappears permanently
into the black hole, where all physical states devolve into the same state.

If we apply this explanation to this theory, it would seem that the matter going inside a black hole
is not destroyed after all. Instead, it forms a part of a new universe.

The world began not with a Bang, but with a Black Hole

===========================
Where does the matter for '' a fourth-dimensional black hole'' come from ?
Where does matter for ''previous cosmos.'' come from ?
The matter came from '' another universe''.
And the matter for ''another universe'' came from some ''another fourth-dimensional black hole''
And so down - down . . . .

The Earth stands on tortoise and this tortoise stands on another tortoise
and so down - down . . . to infinity.

In my opinion we always see standard 3D. Something strange however.

In wireless we can produce a field let's say 1 meter wide when it returns
to the origin it is scaled to 1 cm. We need an event at 1 meter to happen slower
than the when it returns so we can exploit that event using this scale idea.

So what does that have to do with seeing around a planet ?

In outer space our telescopes show us enormous events.
When we scale the electric universe events down to bench top scale
something strange happens. What happens in millions of years
in space happens in a few nanoseconds in our lab scale. The aspect
adjustment between scale and the helical rotations is space-time.

Bend light like a wave, whizzing off a train is not for observers.

In outer enormous space we are weightless.
it means every particle is weightless.
Where is weight came from?
The weight comes in standart 3D.
