quote: We all know light can be affected by gravity. Does this mean that a ray of light has a gravitational attraction on massive bodies?
quote:Originally posted by Soul SurferI am particularly interested in the answer to this question myself and have not yet managed to totally satisfy myself whether the mass increase assocated with kinetic energy increases the gravitational effect of a particle.I have been searching the web for years to find something on relativistic orbit theory ie what to the orbits of objects look like when their velocities become relatavistic but I have found nothing to indicate that they are significantly different. (perihelion rotation apart)
quote:Originally posted by Soul SurferYes that is exactly what I was talking about but the effects do not change the orbit much because the incereased gravitational effect cancels out the relatavistic mass increase if this didn't happen things would accelerate less as the got faster when they are falling into an area with an intense gravitational field because of the relatavistic mass increaseLearn, create, test and tellevolution rules in all thingsGod says so!
quote:Originally posted by Solvay_1927But surely an object must be experiencing a force if it's in orbit - otherwise it would not move in an orbit, it would be moving in a straight line. (Or have I misunderstood what you're saying, George?)
