Drake’s Equation

November 20th, 2022

The equation was formulated in 1961 by Frank Drake. Drake’s Equation is an attempt to estimate the chances of there being intelligent life somewhere out there in the universe, using mathematics and the known values of the universe to estimate the chance that there is intelligent life. Formulated at the first scientific meeting for the search of extraterrestrial intelligence (SETI), it was meant to spur debate, and not meant to be a serious attempt to estimate the amount of civilizations in the Milky Way.

Drake’s Equation is defined in Wikipedia as:

R∗ = the average rate of star formation in our Galaxy

fp = the fraction of those stars that have planets

ne = the average number of planets that can potentially support life per star that has planets

fl = the fraction of planets that could support life that actually develop life at some point

fi = the fraction of planets with life that actually go on to develop intelligent life (civilizations)

fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space

L = the length of time for which such civilizations release detectable signals into space

In the end, Drake’s equation is more of a thought experiment. It is based on a lot of conjecture and highly speculative estimates of the known universe, it’s not like a scientific law or theory. It’s just an attempt to guess how likely life could be, based on some assumptions, and still a good intellectual exercise.

Fermi’s Paradox

November 18th, 2022

I’ve always been fascinated with the concept of Fermi’s paradox, in regards to whether there is life in space or not. Defined on Wikipedia as:

The Fermi paradox is the discrepancy between the lack of conclusive evidence of advanced extraterrestrial life and the apparently high a priori likelihood of its existence, and by extension of obtaining such evidence.

So life should be common, given how many stars and galaxies there are. Intelligent life will eventually develop industry and science, and consequently generate electromagnetic radiation; which can travel at the light ‘c’ and in every direction. So given both of those ideas, why don’t we detect any signals emanating from any other part of the Milky Way galaxy?

Ultimately, we don’t know very much about the true nature of the universe, so we don’t even know for sure if both of the suppositions of the Fermi Paradox are true. So who’s to say :p Thanks for reading
Tour of the Universe

November 15th, 2022

I recently posted my 11th(?) video essay on Youtube, and am deciding to expand my online presence, hence, this thing you are reading. Besides this is a good mean for fleshing out topics, and making addendums.

My most recent video is a Tour of the universe. Imagine you just materialized on Earth all of a sudden, wouldn’t you like a tour of space-time. To locate you, and where you are in the grand mess that is space time?

In this video let’s go across the universe (and galaxy and solar system) and existence starting with where we are on Earth and time with a quick review of human society and geopolitics. Afterwards we blast off into orbit, traveling across to the Moon, Mars, across the solar system, the Oort cloud, visiting Alpha Centauri (nearby Three Body system). Doing a comparison of the sizes of everything in the universe. After getting to know our nearest three star system, Alpha Centauri, the tour of the universe continues to the Milky Way’s center, the super massive black hole ‘Sagittarius A’ in the galactic core. A gigantic black hole that anchors the core of the Milky Way galaxy, with a gravitation force so strong as to bend light in, and trapping anything that gets close to it. Moving further out, we visit the Andromeda the local Local Interstellar Cloud, the Orion Arm, the Milky Way (quick mention to the collision with the Andromeda Galaxy), Local Group, Virgo supercluster, Laniakea Supercluster and finally to the universe as a whole and the end of time and the center of the universe.

Building a connection from the small to the large. This video will tell you how big the universe is and a quick history of the universe. Locate our galaxy and solar system in the universe, and where the milky way Galaxy is from Earth. Learn about our universe. Thanks to NASA and the BBC for the images and real footage. We take a quick and whimsical look at the science, cosmology, astrophysics and chemistry that we know about the material universe we covered a scope of human existence and Society traveling across the entirety of space and time reviewing and light-years the scale of the different masses and bodies that compose our solar system local Galactic facility Galaxy and universe Covering some of the interesting facts physics and science of the different celestial bodies we try to review what we know when we tried to answer where when are we why are we here the most important questions a person can ask themselves A view of the beauty of the stars and the cosmos view through a lens of a scientist exploring the wonders of cosmology. A view of anyone that’s ever looked at the night sky and wondered at what lies out there, in the infinite expanse of the cosmos. A crash course in the scale of existence, starting on our limited view here on our green Earth, to the vastness of the 96 Billion light years vast universe that we are currently in. What happens when Entropy is at a maximum, billions of light years of distance across. Thanks for joining as we explore how our universe works, our universe is not silent, let’s listen to it’s song.

Feel free to reach out to me if you have any questions or curiosities.
