Eric knows there's no sound on the Moon. At least his(?) subtitle -
- is not a science education fail.
Most of the times the title is written by someone else. My guess is that they go to something like https://www.wolframalpha.com/input?i=2.43+km+a+second [1] and copy the most clickbaity version.
[1] I didn't get 7x speed of sound, but you may be more lucky.
"... the impact will probably be too faint to be seen by Earth-based telescopes."
We all know the moon landing happened in a movie studio, so this isn't surprising.
;)
Space isn't a perfect vacuum, especially so near the moon, so there is theoretically a speed of sound, it's just really slow.
"Speed of sound"
Come on Berger, you're better than that.
