Is the 7 second gravity loss even possible?

I promise I’m not trying to seem dumb, I’m also not a conspiracy theorist.

I was told about the rumor where earth would lose gravity for 7 seconds as a result of black holes (???), it immediately comes across as something that doesn’t make sense (I am no physicist). However, I have a lot of anxiety.

Is that even something that would make sense if it were true? My instincts tell me no.
