Consider a long rod AB of length 1 light year….

If a push is given to end A… and a man watches end A from B with a powerful telescope…

Will he feel the push first or see the end A being moved???????????

in space it will take 1 year for light to travel such a distance.but gravity and any change in space dimensions would travel faster than light
