It missed us by 9 days

What if we saw it coming? Could a power grid just shut down and wait? Sure people would lose power to EVERYTHING bit if that was just for a day or 1/2. day wouldn't that be better than the entire US losing power for months or years? Is that even possible?  Not that I can come in with an answer to the problem that none of the top scientists all over the globe (yes globe screw you flat earthers), but just curious if something like that would protect from this. Just wanting to understand it better. :)

BTW I love your channel! One of your videos cam up as a suggestion after I watched one from a different channel.
