    Black hole Hole
AI Thread Summary
Finding a black hole between the Milky Way and Andromeda galaxies is unlikely due to the nature of their gravitational interaction. The galaxies are drawn together by their combined mass and gravity, which primarily consists of dark matter and gas, rather than black holes. Black holes contribute a minimal fraction (less than 0.1%) to the universe's total mass. The movement of space does not support the existence of a black hole at the connection point between these galaxies. Therefore, the search for black holes in this context is not feasible.

If space were like a ocean of ice chunks where everything gradually moves apart and the andromeda galaxy and our galaxy are moving closer to one another. Finding the connection point would find a black hole right. Or is that not possible with the way space moves?

There is no reason to expect a black hole between our galaxy and the Andromeda Galaxy. The galaxies attract each other due to their combined mass/gravity.

Black holes are a tiny contribution (<0.1%) to the overall mass in the universe. The Milky Way and Andromeda have a lot of dark matter, some gas, and a smaller contribution from stars.

Thread 'Asteroid 2024 YR4 has a 1% risk of a multi-megaton impact in 2032 (now ruled out)'

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
