Eric knows there's no sound on the Moon. At least his(?) subtitle -

> The object will be traveling at 2.43 km a second, or 5,400 mph, upon impact.

- 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.
