Because you would not claim that "photons cannot be affected

Or would you? :-D

What is the evidence that photons are deflected by the presence of
matter in space?
The photons are not affected, but space itself is.

This space is therefore depending on the direction of time.

This pass is NOT curved by gravitation, but by curvature of space.

it is good to hear someone here who can plainly explain relativity so
everyone can understand. The only problem is that space is not a
surface, so it can't curve. Non-Euclidean geometry cannot curve space,
so it can't cause gravity. The idea that the concept of curved space is
somehow an improvement over the idea of fields of force is mistaken
because it involves the elementary error of reification fallacy.
Well, let's assume, that relativity is actually correct and 'length
contraction' and 'time dilation' are real phenomena, which can make a
certain space disappear, while another one unfolds.
But his is NOT caused by velocity, as Einstein assumed in SRT, but by
acceleration (as Einstein assumed in GR).
Now we could extend this idea by allowing different directions of the
axis of time, which would also include timelines, which point into the
opposite direction (towords our own time).
The time flowing backwards would have an associated space, too, but one,
that we cannot see.
That space could pass like a ghost throuh our world and we wouldn't
recognize its existence.
But that space is actually real and also populated, while we live in
that 'negative world in a mirror' like ghosts, which passes through
their world like being not there.
Betwenn forward and backwards time we can have a continuum of degrees
and also 'sideways' time, which is a bit difficult to imagine.
Since matter is timelike stable, we are (as all matter) bound to our own
time and could not exist in such a 'mirrored world'. Matter would simply
disapear like in a black hole, if it enters such a realm of negative time. >>
But it would 'pop out of nowhere' in the space behind the mirror and
that is, what we call 'big bang'.
TH
"negative time"???? u got dis thing backwersd...
Space is negative, and Time is positive.
Time is not Left, Time is Right.
Time goes right.
Do you as "Do you have the Left time, sir?" or do you say, "Do you have
the right time, Miss?"
I think about time as a local parameter.
Therefore any point has its own local positve time.
'perpendicular' is space, if yyou regard the axis of time as imaginary
and 'perpendicular' as multiplied by the imaginary unit i.
That's why I think that space is 'relative' (to the local axis of time).
Now we could extend this idea and start a universe from nothing, where
we have one axis of time pointing in some direction, which is balanced
by another axis of time, pointing into the opposite direction.
That 'opposite direction' is also positive time, but only locally.
Now we can have two spaces, which both have a positive time, which are
negative to the other timeline.
Because this construct is 'anti-symmetric', the anti-world is also
filled with anti-matter. That is like 'matter in a mirror'.
That matter is also just usual matter in that 'anti-world' with
'anti-time', because the beings living there know only their own world
and their own time.
Now both worlds could coexist, because they cannot interact easily and
pass through each other like a ghost.
