I'm having some trouble with the concept of Black Holes.
For years I was under the naive impression that a black hole was a kind of void that, with the help of immense gravitational force, draws and compresses all matter and light into it to create somekind of supercritical mass.
I've recently been given the impression that the term black hole is simply used to describe any massive object that seems to effect space in this way. Is it possible that a black hole is not a void at all, but actually an object that is so large to our perspective that we cannot perceive the true nature of it's complexity, only the forces that it exerts on our level of perception? Does anyone have any ideas on this?

Title: Precision Deflection of Electron Beams Using Synchronized Laser Pulses for Trajectory Analysis
Abstract
This study proposes an experimental setup for precision deflection of electron beams using synchronized laser pulses. The experiment aims to explore the dynamics of electron trajectories by inducing a controlled 5-degree deflection and analyzing the resulting paths using a combination of field emission electron microscopes and high-intensity lasers. The primary objective is to achieve detailed mapping of electron interactions within a controlled environment, facilitated by advanced synchronization between the electron emission and laser activation to ensure minimal interference and maximum accuracy.
Introduction
Electron beams, traditionally used in microscopy for imaging at atomic scales, possess potential for detailed physical interaction studies when manipulated with electromagnetic fields. Recent advancements in laser technology allow for precise control over these interactions. This experiment leverages these technologies to induce specific deflection angles in electron beams, facilitating novel investigations into electron dynamics and beam manipulation techniques.
Materials and Methods
Electron Beam Generation
Electron Source: 36 field emission electron microscopes are arranged in a circular configuration around a central target, each configured to emit electrons at 30 keV. Field emission is chosen for its ability to produce sharp, well-defined electron beams suitable for precise interaction studies.
Pulse Modulation: Electron emissions are modulated using RF cavities to produce short pulses with durations matching those of the laser pulses, estimated to be in the picosecond range.
Laser System
Laser Configuration: High-intensity lasers are synchronized with the electron pulses. Each microscope is equipped with a vertically oriented laser designed to deflect the electron beam by 5 degrees.

🧵 JoVE Subscription Authorization Bypass?

So, I enjoy watching science and medical videos. They're very interesting to me. I don't belong to any university or medical school, I just enjoy watching them and learning things, and seeing how science is progressing.
There is one website in particular that I really want to watch videos on, because they have things you can't find anywhere else, but they lock almost everything behind an authorization wall which requires you to belong to a university/school/college/etc that subscribes to them.
If you don't have an email with one of these places and can't verify that you belong to it, you cannot view 99% of their videos.
This website is JoVE https://www.jove.com/
There used to be a way to use pubmed to watch videos from JoVE that had been published for 2 years, but JoVE has since pulled out of pubmed and you can no longer do this.
Does anyone know of any way to bypass their authorization?

Is it possible to learn 1st year of math in 4 months. Total list of modules is Intro Calc, Advanced Calc, Real Analysis, Linear Algebra, Mechanics, Coding, Logic and Computation Theory, Probabilty, Statistics. Didnt do anything or lectures at due to reasons.Decent at math tho. Just wondering if i should take the L here. How hard would it be too pass? How many hours a day would I be looking at?

What is his actual giga I.Q contribution to science?
What is there to evolution beyond what every child is taught in elementary school, survival of the fittest, small changes accumulate over time, eventually new species.
Surely that can’t be all there’s to it? Like in elemntary school you learn that Newton “discoverd” gravity and you’re like “ok whatever that’s kinda evident” but then you learn calculus and realize how insane that Newton invented it, not only that but it was fluency at calculus way beyond what normies lean in high school, and how he used to calculate the motion of planets and solve hard problems and that’s only the tip of the iceberg. You’re left with no choice but to bow down to his genius.
I’ve never felt impressed after watching or reading something related to evolution/paleontology , it all feels like vague conjecture and bickering and then you hear idiots like Dawkins talk about evolutionary psychology and if that sort of nonsense doesn’t bug you, you’re…

This is a comparison of different animals brain size. Bumpiness correlates to intelligence, so what the fuck are dolphins and camels doing with so much intelligence? Can we train them to do complicated maths and shit like Alex the Parrot? Based on this image, it seems like they should be able to intellectually mog apes, who we do most of our experiments with.
https://en.wikipedia.org/wiki/Alex_
Pepperberg said he could identify 50 different objects and recognize quantities up to six; that he could distinguish seven colors and five shapes, and understand the concepts of "bigger", "smaller", "same", and "different", and that he was learning "over" and "under".[2] Alex passed increasingly difficult tests measuring whether humans have achieved Piaget's Substage 6 object permanence. Alex showed surprise and anger when confronted with a nonexistent object or one different from what he had been led to believe was hidden during the tests.[16]
Alex had a vocabulary of over 100 words,[17] but was exceptional in that he appeared to have understanding of what he said. For example, when Alex was shown an object and asked about its shape, color, or material, he could label it correctly.[15] He could describe a key as a key no matter what its size or color, and could determine how the key was different from others.[7] Looking at a mirror, he said "what color", and learned the word "grey" after being told "grey" six times.[18] This made him the first non-human animal to have ever asked a question, let alone an existential one (apes who have been trained to use sign-language have so far failed to ever ask a single question).[19]
