The instant of the Big Bang gave birth to hydrogen, helium and a small amount of lithium. Hydrogen and helium are the main elements that fuse to give stars their heat, energy and intrinsic brightness. When discussing matters of cosmology I may have neglected lithium slightly. Lithium is one of the oldest elements in the … Continue reading Where Did All The Lithium Go?
In the past year of blogging for GLAMsci, most questions and feedback came from the speed of light series. I thought some housekeeping was in order to post an answer to the most frequently asked question - why isn't the speed of light infinite? To be fair, in my posts I discussed the finding of … Continue reading Why Is The Speed of Light Finite?
As far as the human race can tell, we humans seem to live on the only planet with any form of intelligent life on it. Since the late 1960s mankind has been to or sent probes and telescopes outside the Earth to find out more about the Universe. Science fiction has given extraterrestrial life a … Continue reading

Approximately 4.6 billion years ago our solar system started to form. The Big Bang being 9.2 Billion years before our own solar system started to form. By this time the universe looked pretty much as it does now due to the 9.2 billion years worth of expansion and cooling. Within those 9.2 billion years hundreds … Continue reading The Origin of Life Series Part 2 : Formation of Life on Earth.
Carl Sagan famously proclaimed that we are all made of stars. Whilst this particular quote looks well on Facebook Cover Photos and on canvas wall prints at home, it actually has a significant amount of truth in it. Everything around us, including us, have building blocks which make us who we are as a species. … Continue reading The Origin of Life Series : We’re All Made of Stars
Recently, the topic of the global warming appeared in the news again, mostly in connection to the newly appointed U.S president and his cabinet; seemingly not having much of support in the current Washington administration. The question we need to ask is: What is the evidence for the global warning, and can we possibly reject … Continue reading Changing climate – the evidence behind our biggest environmental challenge
Astronomers involved in The Pale Dot Project found a potentially habitable planet orbiting Proxima Centauri. Named Proxima Centauri b, the planet orbits its parent star Proxima Centauri in around 11 days, with surface temperature favourable for the presence of liquid water on its surface. This rocky world has a slightly bigger mass than Earth, and … Continue reading Discovery of an Exoplanet within habitable zone around the star closest to Earth.
It is fair to say that absolutely everybody knows who Albert Einstein is. What many people don't know is why he is regarded as a genius. Einstein's theories of Special and General Relativity have transformed our notion of reality and these theories are central to modern physics. They govern the laws of nature and our … Continue reading Introduction to Special Relativity
So far, we have focused on the grandeur and scale of the heavenly bodies and how they were formed in the Primordial Era of our Universe following the Big Bang. Visible matter i.e. stars, galaxies, planets, nebulae, interstellar dust, comets and asteroids only accounts for 5% of what the universe is actually made of. In … Continue reading Electrons, Quarks, The Higgs Field and The Building Blocks of the Universe
