One of my favorite videos of hers this year.
Being a natural geometric savant (yes I was an autistic study kid of the 80s) I find their work fascinating though Exceptional Lia algebra frameworks though so few take this route. Even less also do work rectifying it with Teleparallel gravity work.

According to a new paper published by a group of astrophysicists, simulations seem to indicate that our galaxy cluster exists in a thin area of highly concentrated dark matter, which itself is located between two voids of dark matter.

I got some questions about the appearance of my name in Jeffrey Epstein's inbox. Turns out to be about... quantum gravity, unbelievable as that sounds. Here is the story and why I am still pissed off about this.
