Honest thoughts/feelings about this?

>Women paid hard for our species to become bipedal and use tools/weapons with their arms.

>Their hips and birth canals had to become narrow and as a result child birth became painful, dangerous for both the baby and mother, and babies were born well before maturity compared to practically every other mammal.

>As a result females had to become very choosy since child bearing was very costly for them, ie their standard for mates exceeded well beyond what the average male was capable of.

>As a result forceful intercourse was the only viable way for the vast majority of males to reproduce and those females who couldn't self lubricate during forceful intercourse were at risk of tearing and infection, and eventually death. Female arousal and orgasm would produce contractions that help transport the sperm into the uterus, which is necessary because the average male penis (3.8" in Neanderthals) is not long enough to breach the cervix.

>tl;dr rape is a social construct and impossible from both a biological and evolutionary standpoint.

What Material is the Singularly of a Black Hole made out of?

No.11865207 ViewReplyOriginalReport
Since Black holes have a Gravitational Pull so strong that light cannot escape, the Core of the Black Hole called the Singularly, have extreme pressure due to it's strong gravity and the Matter being densely packed in a small space. Imagine what Material is being created in a Black Hole due to extreme pressure, gravity, and density? Imagine there is a Black Hole approaching the Solar System and before the Black Hole pulls Planets into itself, it explodes due to old age by Hawking Radiation and scatters the fragments of the Singularly everywhere. When one of the Fragments of the Singularly lands on Earth, World Governments would be fighting each other because the Singularly Fragment might have Special Property.

Retarded question: where's the need of solving a differential equation?

Retarded question: where's the need of solving a differential equation or a sistem of DE?
Where is the need?
To calculate the rate of variation of 2 functions?
Couldn't it be made with trigonometry instead of calculus?
