I have a hypothesis regarding the lowering of male fertility.
In the past, obviously, very healthy sperm was a good thing, evolutionarily speaking.
However, since the normalization of abortion, sperm that works on the first go is more likely to not reproduce: the woman gets pregnant with a guy she only just met, gets an abortion, and the abortion often causes them to ultimately split up and be more careful in the meantime. On the other hand, crappy sperm allows a couple to enjoy sex many times before having an "accident", by which point they have bonded sufficiently to be much more likely to keep the foetus.
Inb4 evolution doesn't work that fast.
Maybe, but bear in mind that sperm mobility genes are the fastest evolving genes. And when you are considering things like abortion, the evolutionary pressures are more like farm breeding than slight advantages in the context of life in general.

Found these in an apartment I'm moving into. What are they?

What does the square root of -1 taste like?

A Chinese Satellite Just Grappled Another And Pulled It Out Of Orbit
>A Chinese satellite was observed grabbing another satellite and pulling it out of its normal geosynchronous orbit and into a “super-graveyard drift orbit.” The maneuver raises questions about the potential applications of these types of satellites designed to maneuver close to other satellites for inspection or manipulation and adds to growing concerns about China's space program overall.
>The unusual maneuver was observed by telescopes belonging to commercial space awareness firm Exoanalytic Solutions. During a webinar hosted by the Center for Strategic and International Studies (CSIS) this week, Exoanalytic Solutions’ Brien Flewelling said the SJ-21 satellite “appears to be functioning as a space tug.” Space Command did not respond to a request for comment, Breaking Defense reports.
>The method used is unknown, but is rumored to be using a large net.

It's over burgers, Chinese can literally fish your satellites.

What if a black hole rotates so fast that the matter just underneath the event horizon is moving just below the speed of light?
What if you add additional angular momentum?

science is responsible for this tragedy

Lots of news saying Ivermectin is effective against COVID-19 because Japan said it was effective.

Japan came out and clarified that the trials of Ivermectin showing efficacy against COVID-19 was NOT done on humans.

What do we think? Is this scientifically valid?

This is cool

This shows 200 iterations of the complex number 'c' by using the Mandelbrot set formula. The next iteration makes a new point and it connects to the previous one with a line. The next iteration is always the previous one squared plus 'c'. So it looks like this:

1. iteration = c
2. iteration = c^2 + c
3. iteration = (c^2 + c)^2 + c
4. iteration = ((c^2 + c)^2 + c)^2 + c
etc...

The Mandelbrot set is basically the region of all complex numbers with the condition that iterating it will never produce an absolute value greater than 2. The number 2 is important because if the absolute value was more than that, adding more iterations would make it grow towards infinity. The shaded region is the region where you can put the point C so that the graph stays inside the red circle. It makes nice patterns if you click and drag it and try to put it close the to edge.

Complex numbers don't work on Desmos so I used points to simulate complex numbers. There would have been probably some more efficient way to do it but at least it still works at 2 fps

What would happen if a person got rid of all instinct? They would be able to do things associated with instinctual behavior, but they would feel no innate desire to do so. What would we get? Schizoidness? AI?
