Unless your data includes gravitational lensing then it isn't valid.No
In reality, gravity affects photons much the same as it affects you and me.
Gravity doesn't slow down the photon velocity as it might affect any other real mass.
As I have already informed the gravitational lensing is actually a curvature in space time due to the ultra gravity force.
Even so, that curvature in space is the base for the curvature in the light/photon.
In any case, it doesn't change the velocity of the photon as it should chage any real mass/object that would penetrate to that aria.
That proves that photon has no mass.
If you use hard gammas, then most of them would turn into pairs.Well, first you have to prove that the pure BBT energy could set those gammas.
You have already known that photons and gammas are all about EM.
For EM you need Electro/magnetic waves/fields
You have to agree that there were no Dynamo or magnets at the early Universe.
Therefore, there is no EM. Without EM there is no photons or high energetic photons as Gammas..
Even if you wish to believe that photons would be created, why are you so sure that those photons are energetic?
How a pure energy could set photons at ultra high energy?
Based on the BBT, the space itself is expanding. So, any mass or mass less particale must move with the space.
So nothing could move faster than the space expansion.
However, the photon/gammas must move at the speed of light with reference to their space time. Therefore if there photons/gammas they had to break the envelop of the expanding universe.
This is one more explanation why photons/gammas can't be created at the early Universe.
much faster than the space expansion.
"For photons with high photon energy (MeV scale and higher), pair production is the dominant mode of photon interaction with matter. "Yes I do.
Do you remember that page?
However, now I understand that this isn't realistic.
Photons/gammas cross the space of our current universe.
The space is full with mass and atoms.
So if that idea was correct, then any photon/gammas had to be converted to the particle pair.
However, this isn't the case; We clearly can observe those photons/gammas as they cross the space without any pair creation.
Quote from: Dave Lev on Today at 04:30:10You do not answer the question:
Would you kindly explain why the energetic photons could cross the Hydrogen chamber, the space which is full with Hydrogen atoms and our atmosphere without being transformed into new pair particles?
In much the same was as Xrays, gamma rays usually go through matter.
If the following imagination that photons are converted to the new particle pair as they move near by mass, then why we can't observe that process in our universe or even in the Hydrogen chamber?
Why we can clearly see the pair particle process due to shooting an atom to the chamber, while we can't see the same pair process by shooting energetic photons to that chamber?
If we can't observe the pair creation process by photons as we see with atom, thean this idea is not relevant.
