A photon exiting the Sun is subject to heat. Isn't heat a force?
?????
Not following you. The hydrogen and helium at the Sun's surface are hot and give off photons to get rid of energy. Once the photon is emitted it travels until it interacts with another bit of matter. What force do you think is acting upon it?
You're asking a question that probably has no answer to your satisfaction. Like others here, you seem to know EVERYTHING about energy! Congratulations!
In your example, in our space-time, the emitted photon will continue to travel to space-time that is cooler than the area it just left. Again, this is our limited 5 senses version of what we think we're seeing. Traveling at the speed of light, the photon itself does not experience time at all; it's here AND there all at once. Makes no logical sense to me at all, but I'm sure you understand that completely, because again, you know everything
wow! did not expect such a whiney response from
you. buck up man
while I am OK with the whole photons having no time or distance in their reference frame, we dont live there and cannot even visit.
there are two types of photons; paid in advance and cash on delivery virtual ones. radiative or reactive.
the type we have been talking about are radiative photons, that shed energy, have a colour. IR, visible, UV etc. they are created by the internal conditions of the bit of matter that emits them. paid in full at the time of creation.
reactive photons carry the force in electric or magnetic fields. they can be attractive or repulsive. they have no 'colour'. more than just that, they need both an emitter AND a receptor to exist. this is where the no time and no distance reference frame comes into play. a bit of matter that is electrically or magnetically active 'borrows' energy to form a virtual photon capable of carrying the electric or magnetic force. because a photon exists in all space along its trajectory it knows whether it will find a partner to swap force with (and in which direction), and the energy is paid and the photon becomes real. if no partner is found then the virtual photon simply ceases to exist after the incredibly short time interval that The Uncertainty Principle allows the energy to be borrowed for.
is it possible that all types of photons start off as virtual photons and only come into existence if they find a partner? sure. but radiative photons interact with most types of matter and there is no tag that displays temperature on any bit of matter. temperature is a meaningless concept for just one bit of matter. temperature is a description of the average kinetic speed of a large collection of bits of matter, within a proscribed locale. the individual bits in that locale have a wide range of speeds. So....does the photon have to not only pick out the right temperature object to hit, but the particle that is also travelling at the right speed as well?
