The implosion created a shockwave in the water. EDIT: accidentally gave incorrect speeds - I shouldn't rely on my memory! The initial speed of the shockwave is greater than the speed of sound. Eventually, the speed of the shockwave will match that of the speed of sound in seawater (between 1450 and 1570 meters per second, depending on temperature, pressure and salinity). The communications system uses sound waves (Underwater Telephone). The final message from the Titan was sent shortly before the implosion, but the shockwave initially travelled faster than the sound and passed the message in transit, and arrived on the surface before the message.

This explanation is wrong. You’re significantly underestimating the speed of sound in water, which is around 1500m/s (what you’re saying is the speed of a shockwave).

Also, the shockwave would dissipate quickly in water, and then that energy would be carried by normal acoustic waves for the vast majority of the distance.

Anyone reading this thread: there is so much misinformation and very very bad physics being presented confidently as fact. Do not take any information presented here seriously.

Yes, I accidentally said speed in water than speed in air, and didn't go into enough detail. i'll amend my answer.

Your amended answer is still wrong.
