Event Horizon Telescope (Episode 4: EHT and the General Relativity Theory)
Lecture (Video) Main Content How EHT proves the perdiction of General Relativity Theory proposed by Einstein? Shadow of a Black Hole: created by the gravitational bending of light near the Black Hole, and it’s larger than the Event Horizon because it also includes the area where light is absorbed into the Black Hole or bent […]
Event Horizon Telescope (Episode 1: Black Hole and the EHT)
Lecture (Video) Main Content Black Holes and the EHT How Does the EHT Work? Photos made from separate telescopes are put together to create a more detailed image. Effort of the Scientists in EHT Project
Black Hole (Episode 4: Black Hole Jet)
Lecture (video) Main Content Jet comprise of very hot gas and a magnetic field, which together move at a speed very close to speed of light. Aaccording to special relativity, that means they will be emitted as beam. In 1918, Heber Curtis discovered the first jet, it turned out belonged to the supermasive black hole […]
Black Hole (Episode 3: intermediate & supermassive & ultramassive back holes)
Lecture (video) Main Content Intermediate-Mass Black Holes: Unlike other black holes (stellar-mass black holes can be revealed by x-ray emission or gravitational waves and supermassive black holes can be revealed by the distorted orbits of nearby stars), the ways to find intermediate-mass black holes is always a mystery. However, if we can find it in […]
Black Hole (Episode 2: General Structure of Black hole + Different Types of Black Hole)
Lecture (video) Main Content: General Structure of a Black Hole The singularity is an abstract point that doesn’t exist in real life but exist in mathematical formulas, it formed because of the extremely high gravitational pull (a really large space-time curvature). The radius of the event horizon is called the Schwarzchild’s radius. When the radius […]
Black Hole (Episode 1: The Origin of a Black Hole)
Lecture (video) Main Content First theory: Stellar Collapse + Supernova explosion Our universe is full of stars, some die quietly at the end of their life, some explode spectacularly which give birth to black holes.If you have a supermassive star hundreds times massive than the sun, Nuclear fusion (burning hydrogen into helium and then into […]
