Myth - When 2⃣ Black Holes are about to Collide, Object around them Can Travel Backward In Time .
Fact - The fact is, they DON'T. This fake fact was popularized by Neil deGrasse Tyson and preassumably, science pages took whatever he said to be true. This could prolly have passed as true around 30-40 years back, but Stephen Hawking in 1992 showed that time travel to past isn't possible without the existence of exotic matter, of which we haven't found any existence up to this point.
