In principle, would an Amtrak Superliner be able to operate into northern Mexico, if desired? Or would the loading gauge preclude this (as it does on some lines in the eastern USA)? 2601:646:8E01:7E0B:61B1:2817:FCB1:9B27 ( talk) 03:35, 8 February 2018 (UTC)
A report in the London Daily Telegraph of 31 January [1] says:
Whales are known for their impressive communications skills which allow pods to "talk" to each other through complex clicks and singing, even when they are 100 miles apart.
Later it says:
Whales also use their tails and fins to make loud slapping noises on the surface of the water to communicate with each other non-verbally.
The sound can be heard for hundreds of feet below the surface and may be a warning sign to other members of the pod.
What is the maximum distance sound can travel through different propagating mediums? (I know that it can't travel through a vacuum at all). It appears that sonar only travels a few miles. 92.19.173.221 ( talk) 11:05, 8 February 2018 (UTC)
