Claims a), b), d) at least, are not what is observed.
Pure speculation is not allow in the Astro-Cosmo subforum.

No. All the normal matter in the universe has only 5% of the mass needed to make the universe flat.
If that was all we had, space would have been negatively curved, not flat.
This is the physical law, coming from Einstein's general relativity.
Now, we observe the effects of about 25% of some unseen matter (e.g. dark matter),
but even adding that in, our space cannot be flat - it is still negatively curved.
Yet we have observational proof (from CMB) that it is very, very close to spatially flat.
Please do not speculate - show a credible reference and then we can continue here;
otherwise this thread will be shifted to somewhere other than the Cosmology section.

Wrong conclusion. Open, perhaps infinite, but not flat

All forms of energy create gravitational fields,
but all forms of energy do not create electromagnetic fields.
Hence gravity is not indivisible from the electromagnetic force.

aspects of objective reality
b) In Einstein's theories, the ideas of absolute time and space were superseded by
the notion of absolute spacetime in special relativity, and curved absolute spacetime
in general relativity
c) SRT is theory without gravity but with an absolute spacetime.
It means, we need to take Newton's absolute time and Newton's absolute space
simultaneously together in order to have Einstein's spacetime.
Newton's absolute time + Newton's absolute space = Einstein's spacetime.
d) And this absolute spacetime can be curved by masses ( for example:
by Sun masses ) in some local region of absolute Einstein's spacetime.
e) According to GRT the curvature depends on masses and its speed.
And because masses (of stars and planets) are different so every local
region has its own gravity-space and gravity-time. For example: Earth
has its own gravity-space and gravity-time, and Venus or Mars has
another gravity-space and gravity-time. But for humans on the Earth
their Earth's gravity-space and Earth's gravity-time seems absolute.

any researchers believe that physics will not be complete until it can explain not just
the behaviour of space and time, but where these entities come from.

I want to correct Zeeya Merali.
It needs to write:
Many researchers believe that physics will not be complete until it can explain not just
the behaviour of Gravity-space and Gravity-time, but where these entities come from.
A three-dimensional (3D) universe contains black holes and strings governed solely by gravity, whereas its 2D boundary contains ordinary particles governed solely by quantum-field theory. Anything happening in the 3D interior can be described as a process on the 2D boundary, and vice versa.

I looked over the article. I want to point the reader's eyes to the diagram
that describes "Holography". It reads :A three-dimensional (3D) universe contains black holes and strings governed
solely by gravity, whereas its 2D boundary contains ordinary particles governed
solely by quantum-field theory.
Anything happening in the 3D interior can be described as a process
on the 2D boundary, and vice versa.
This is probably the most concise description of the `Holographic Principle` I have ever read.

Jagg fails to make the case for me that Kelvin is anything more than a temperature scale.

Mark Jagg’s article ”ZeroKelvinTheory.com” has idea

thermal and ''electro-energy'' phenomena . . .
and ''Potential ability can become Kinetic ''
/ potential ability of universe with 0°Kelvin temperature /
