Some smart guy answer me this;
Anything with mass can not go the speed of light,
Photons therefore should have no mass.
Gravity only acts upon things that have mass.
Trick question, we don’t know.
before all the Liberals and politicians spout off
about “settled science”
I think we had better be very thoughtful.
Light is tricky in that it acts as both a particle - photon - and a wave.
Personally I have come to believe that particles are merely vibrational waves that are moving at such a high frequency that the waveform condenses into mass.
The conversion of mass to energy is a really just a disruption of the higher frequency’s waveform where a portion is converted to a lower frequency - energy and the remainder (ash left from a flame for example - is the portion that is modified but still remains at a higher frequency and in a material form.
It’s been way to long since I got my Physics degree so I can’t do the math anymore, but I think the idea deals with the niceties of string theory as well as the “missing Mass” of the universe leading to the whole dark matter/dark energy theories.
I also am not convinced by the constancy around the speed of light - I remember when we went through those equations at the time that I didn’t feel the differential equations even considered the potential for variance in C and felt they were oversimplifying the math....but then again I was just trying to pass the courses and it was about the most I could do just to manage that.
