💡🔮Quick Fact🔮💡
#Final-part7
The future of the universe may depend on how much dark matter there is. If there is too much, its gravity will eventually stop the Universe's expansion, and make it shrink again😨
A galaxy's bright stars may be only a tiny parts of its total matter. Much of the galaxy may be invisible dark matter
📌This week's discussion about Dark Matter has ended.

Introduction to Quantum Mechanics
By David J. Griffiths
This book first teaches learners how to do quantum mechanics, and then provides them with a more insightful discussion of what itmeans. Fundamental principles are covered, quantum theory presented, and special techniques developed for attacking realistic problems.
The books two-part coverage organizes topics under basic theory, and assembles an arsenal of approximation schemes with illustrative applications

Time for important laws
Canada has introduced a new criminal code for crimes on the Moon. From now on, astronauts who committed misconduct can be officially prosecuted.
Everyone willing to rob aliens will now answer to the law in Canada😁

For the first time in 50 years: the U.S. Defense Department will hold hearings on UFOs
✨Previously, U.S. intelligence published a preliminary assessment of 144 reports of "unidentified airborne phenomena" since 2004.
On May 17, a closed secret hearing on a Pentagon program, known as the Aerial Object Identification and Control Group, will be held. It was created in 2021 after U.S. intelligence released an estimate of 144 reports of "unidentified airborne phenomena" and could explain only one✨

How big is the ISS?
✨Inside, it appears to be about a 6-bedroom house. Typically, there are 3 to 6 astronauts and cosmonauts staying there and working on the ISS for 6 months 🛰
According to the astronauts, being in such a confined space with the same people for long periods of time is psychologically difficult.
The crew is formed 2.5 years before the flight, and only the most stress-resistant candidates are selected. During this time, astronauts train together, go on missions, take survival courses, work and even become family friends.
And if suddenly antipathy arises between the crew members, they, as a rule, warn their superiors about it✨

#AstroQuestions --WHAT WAS BEFORE BIG BANG?? Comment below👇👇👇 Share: @AstroMechanics
Answer:- It's possible that before the Big Bang, the universe was an infinite stretch of an ultrahot, dense material, persisting in a steady state until, for some reason, the Big Bang occured. This extra-dense universe may have been governed by quantum mechanics, the physics of the extremely small scale.

Introduction to Quantum Mechanics.
#Part1🔭
✨Quantum mechanics is a branch of physics that describes the behavior of matter and energy at the atomic and subatomic level. It was developed by a number of physicists in the early 20th century, including Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, and others
Quantum mechanics based on the principles of wave-particle duality, uncertainty and superposition.
In quantum mechanics, particles such as electrons and photons are described by wavefunctions, which represent the probability of finding the particle in a particular location or state.
📌The development of quantum mechanics was a gradual process, with contributions from many researchers, rather than the work of a single individual.

What are the types of Quantum Mechanics?
#Part2🔭
✨There are several different types of quantum mechanics, each with its own focus helps to understand the behavior of matter and energy at the quantum level. Here are a few examples
Non-relativistic quantum mechanics:deals with the behavior of particles like electrons and atoms in the absence of strong gravitational fields, based on the Schrödinger equation.
Relativistic quantum mechanics:extends these principles to include the effects of special relativity, necessary for describing particles moving at high speeds or in strong gravitational fields.
Quantum field theory:describes how particles interact.
Quantum information theory:studies how quantum systems process and communicate information.
Quantum thermodynamics:studies how quantum mechanics affects thermodynamics
📌Each with its own principles, methods, and applications. Together, they form a framework for understanding the behavior of matter and energy at the quantum level✨

What is the most surprising or counterintuitive aspect of quantum mechanics?
#Part3🔭
✨One of the most surprising and counterintuitive aspects of quantum mechanics is the principle of wave-particle duality. This principle states that particles, such as electrons or photons, can exhibit both wave-like and particle-like behavior, depending on how they are observed or measured.
This duality is surprising and counterintuitive because it challenges our classical understanding of the behavior of particles and waves. In classical physics, particles are discrete objects that move in a predictable manner, while waves are continuous and spread out. In quantum mechanics, however, particles can exhibit wave-like behavior, and waves can be described as discrete packets of energy, or particles.
The principle of wave-particle duality has profound implications for our understanding of the nature of matter and the behavior of particles at the atomic and subatomic level✨
