Can a Starfleet vessel travel at exactly the speed of light so that a supernova appears to be frozen at a given moment in its blast and have more time to study?

If this is possible, could the ship move forward and back to any given moment of the blast and study that particular instant?

In theory, but that works only with sensors that inspect the electromagnetic spectrum. While that's certainly *helpful*, standard sensors function through manipulation of subspace. This is a faster-than-light process, so you can't take advantage of dancing around the speed of light issue, and also has a rather serious quality issue at very long ranges.

The advantage is that you can drop expendable probes around a star that's about to explode and have plenty of time for them to transfer all the information back to their home ship before the slower-than-light shockwave reaches the probes.
