Time cannot be an illusion because it compares rates of change. Change
would have to be an illusion for time to be an illusion. Are you Hindu?
Time is not an illusion in Dr. Hachel's thinking. Richard Hachel considers
that proper times are real.
Simply, an event measured by a proper watch does not have the same
duration as an event measured elsewhere (in another frame of reference)
than another watch.
If we place ourselves at the level of a photon receiver (my retina for
example) or if we ride a photon, we realize that the time of a transfer
over 13 billion light years is instantaneous. We note tau=0.
Neither the photon nor my retina has aged by a single microsecond during
this entire transfer.
A transverse observer, placed in our inertial frame of reference, but very
far away, will consider that the time of the transfer is 13 billion light years.
An observer placed at the source will consider that a photon has just been snatched from him, without knowing who snatched it from him (it is the receiver), nor where it will go.
It will take him 26 billion years to find out.
The transfer, for the source, takes place over 26 billion years.
This is where time is relative, and this is quite difficult to understand
for those who do not have the keys.
The simple student does not understand why it is instantaneous for the receiver, and why it takes so much time for the source, while the photon
itself does not age by an instant (its time is zero).
This also calls into question the very existence of the photon between its source and its receiver. A green unicorn whose proper time is absolutely
zero has no time to exist at all.
The photon is the same.
It is therefore only a quantum of energy instantly changed in the
receiver's frame of reference and of itself.
Everything happens at the same time.
The rest is only spatio-temporal deformation.
