The light is emitting in all directions so it doesn’t apply any force to the system. The point I am making is that the system is losing mass and so it has to increase in velocity to conserve momentum.
And, when I say losing mass I mean that the mass is being converted into light energy which...
Bandersnatch: the mass of a star lost is very small, but the "acceleration" due to dark energy is very small too. i am not trying to explain the total velocity of the star. i am trying to explain the increase in velocity which is now attributed to dark energy.
if a star has a given momentum...
i guess i mean momentum. momentum is mass x velocity. if a star has a certain momentum away from an arbitrary point. if you reduce the mass, the velocity has to increase to keep the momentum constant. because you can't gain or lose momentum without being acted upon by an outside force...
the star's motion away from each other. or, from our point of view, the star's motion away from us. if that momentum is constant but the mass decreases, the velocity should increase in order to balance the equation. because the mass that is turned into energy is dropped from the equation the...
well, there is no relationship between the two stars except that they are both moving away from each other. or, away from some imaginary arbitrary point between the two stars. but the motion of those two stars relative to each other or relative to any arbitrary fixed point should slightly...
ok, thanks for that explanation. I guess the question i still have is why would it not have any effects on a cosmological scale? if a star is moving away from us at a certain velocity and that star is losing mass, why would it not appear to be moving faster away from us from our point of view...
even within the confines of the balloon theory my question is still valid. if two stars are moving away from each other because of an applied force that is no longer being applied, their velocity should still be constant. but if the mass of the stars are slowly reducing due to a conversion of...
not sure where to post this question... kind of a thought experiment... if a mass is given an initial force in a frictionless environment, like space. it would continue to move forward away from the applied force at a constant rate until acted upon by another force. if you were to remove...
