Let's say we have gun that fires a bullet at 1000 m/s horizontally when high up in a gravitational potential.(adsbygoogle = window.adsbygoogle || []).push({});

Now we take the gun deeper into the gravitational well to a point where the gravitational redshift factor is higher by a factor of 4. Will the muzzle velocity be the same, faster or slower as measured by a local observer?
