What If a Black Hole Flew By Earth at the Speed of Light?

A small but incredibly fast unwanted guest is about to swing past Earth at the speed of light. Yeah, this is the tiniest black hole in the Universe. But despite its small size, could it rip our planet apart? In this video, we’re sending black holes through Earth, from the tiniest black hole just 2 cm (3/4 in) in diameter… to the most massive, stupendously large black hole. For you on Earth, things are about to get bad.

Ayy… but uh.. Nothing with mass can travel at the speed of light… bc the speed of light approaches infinite mass bruh.

Use TON 618 instead, it’s mass is far more accurate than Phoenix A

Can you make "What if you go to black hole and enter black hole" Pls 🥺

Um, if the black hole is traveling at the speed of light, ie, the speed of causality, no one on earth would ever see the effects in the stars, Jupiter, etc, because the time it takes to see it would be the exact time the black hole reaches earth. Being this blatantly wrong and skirting over the most important, fundamental law of physics is … sloppy, to say the least.

not 1 minute in i asked myself, even if it flew by at light speed, wouldn't we still feel the powerful pull regardless of its size even over a year of its travel? Because they're so dense and all?

It wouldnt weigh as much as a mountain, it would have as much mass as a mountain. Weight is the effect of gravity and in this case, earth's gravity pulling on you. @WhatIf
