Black Holes – The Darkest Objects

January 17th, 2023

Continuing with my excuse to read up on the crazy stuff in space, have a new video, on Black Holes, one of the most mysterious and the darkest objects in the universe.

Besides, singularity is a cool/fun word to say

Black holes represents an oddity in space and the universe, they are singularities of mass. Representing points of immensely high density that is able to completely warp and break the law of physics and space time. Their massive gravitational fields make it so that no light, object or anything can escape the gravitational field of a black hole.

In this video, we’ll go over the basics of what black holes are, their physics, what types of black holes exists, the closest super massive black hole (Sagittarius A), Hawking radiation, Neutron Stars and their connection with black holes, Black holes in the media, how telescopes like the James Webb help, neutrinos and black holes, quasars (quasi stellar radio sources), and lastly, what happens if you fall into black holes.

I personally find black holes mesmerizing and fascinating due to how little we know about them, and how our understanding of physics and science breaks down when space time is so warped by intense gravitational field. The mass they represent is mind bogglingly huge, with super massive black hole can have masses beyond 1 billion solar masses!

So join us on a overview of what we know about the Darkest Objects in the universe, these mysterious singularities formed through space.

On the left, an optical image from the Digitized Sky Survey shows Cygnus X-1, outlined in a red box. Cygnus X-1 is located near large active regions of star formation in the Milky Way, as seen in this image that spans some 700 light years across. An artist’s illustration on the right depicts what astronomers think is happening within the Cygnus X-1 system. Cygnus X-1 is a so-called stellar-mass black hole, a class of black holes that comes from the collapse of a massive star. New studies with data from Chandra and several other telescopes have determined the black hole’s spin, mass, and distance with unprecedented accuracy.

Welcome to the Universe (Short Series)

December 2nd, 2022

Something I have found interesting about Youtube shorts is that it runs on a completely different algorithm then the main Youtube algorithm, meaning that each creator has a chance to explore two different mediums (one limited to at most one minute, and vertical format) and the other one being standard horizontal videos of any lenght.

I have already posted about the “Tour of the Universe” video I released recently (https://youtu.be/1ccmMlG_K9E). So I thought I would try converting the content to shorts, so as to reach a different audience, and to have the content presentable in short, easy to get through clips.

Something else I am trying out is the assumption that most people like learning, and exploring the Universe, but might not have the time/energy/attention/focus for a longer video on astrophysics. So kinda of trying to make scientific content for a more ADD or busy generation via shorts. Also, the visuals of the video are pretty, and thought they might do well in a mobile format.

I did also edit down the material, removing some jokes that on 2nd thought I don’t think landed, or just removing some parts for brevity and flow. Still covers all the major points, just as Earth, Moon, Mars, Oort Cloud, Alpha Centauri, Milky Way and Andromeda Galaxies, Local Group, Virgo Supercluster, Lanaikai and vast span of the ever expanding universe.

Enjoy the shorts/mobile tour of the universe: https://youtube.com/playlist?list=PLvLRH9nbBGMUcH2M10bbZLUN1vwLK1Y7A
