lets use the expanding dough and raisin analogy. here the particle observed in the galaxy is inside the raisin moving at some velocity v close to c. the dough itself is expanding with any velocity V . hence, would it mean, to a observer on some other part of the dough in some other raisin , the...
not all motion is relative. only the measured value is relative. whether the motion is observed or not , the particle or whatever being observed is in motion because of the expansion of the universe and also due to its own energy. hence it would be impossible to find the correct value of the...
so if the galaxy is moving with the resulting speed of 3.11 c , then aren't the particles in that galaxy violating the local speed limit. (because the recession velocity is added to the local velocity of the particle.).
also in calculating the recession velocity using Hubble law, is the...
but if both of the observers (on the Earth and space ship) are already in motion such that both Earth and spaceship are moving at 5 km/s , and 100km/s is the measured relative value. but the actual value is 105 km/s . hence the 5 km/s value is not known unless a absolute frame of reference is...
so is it impossible to determine whether any measurement like velocity made by an observer(in a inertial frame) of an event occurring in the same frame of the observer or any other frame(inertial or non inertial) is the correct value of the quantity , since the velocity of the frame of the...
how is it possible that measurement made from a inertial frame is correct irrespective of the velocity of the inertial frame, which itself is not possible to know without an absolute frame . hence any measurement made from a inertial frame is relative , isn't it? then how is the measured value...
isn't a stationary inertial frame of reference similar to the absolute frame of reference? also if it is proved that something in the universe is at absolute rest, than would a absolute frame of reference be accepted?
then, would that mean its possible that galaxies have their own motion and the space itself has its own motion. and for both their motion the speed limit is c. hence the maximum possible observable velocity of a galaxy is 2c for a observer in a absolute frame of reference F (the frame F is at...
i have a question about the motion of galaxies and the speed limit of light.
using Hubble's law, it is theoretically found that after a certain distance(about 4200 mega parsec or something) from a observer, the galaxies are moving faster than the speed of light.
consider the following...
