The strong nuclear force is the tight binding of protons and neutrons to a nucleus. It's opposite number, the weak nuclear force, is responsible for radioactive decay. In other words, the atomic nucleus breaking down into smaller nuclei. Soon after the Big Bang, the four forces of Nature became what we know them to be … Continue reading Forces of Nature Series: The Weak Nuclear Force
Time to go back 13.8 billion years to the instant of the Big Bang. The Big Bang is the leading model of how the Universe began and isn't debated very widely other than believers of models of Creationism. With the two pillars of relativity and quantum mechanics, the earliest moment the laws of physics as … Continue reading Forces of Nature Series : The Strong Nuclear Force
The laws of physics and the Universe we live in comes under four distinct forces that govern all of nature and reality. All of these forces are evident and observable across both branches of classical physics; relativity and quantum mechanics. They are also called the four fundamental interactions, in short they can't be reduced to … Continue reading The Forces of Nature Series
Credit : Upriser The observable universe that we live in has 93 billion light years in diameter worth of galaxies and wonders for us to observe with our telescopes. At the moment 46.5 billion light years in every direction of Earth is the farthest our telescopes can reach. To put this into perspective, the light … Continue reading The Multiverse : The Infinite Possibilities
Wave/particle duality and the superposition of states form the groundwork of The Copenhagen Interpretation of Quantum Mechanics. This interpretation illustrates that particles can exist in all states at any location until it is definitely measured and observed. Credit : University of Oregon Erwin Schrodinger, an Austrian quantum physicist, was skeptical of the interpretation and came … Continue reading Is The Cat Alive or Dead?
Credit: Science and NonDuality Quantum Field Theory became seriously recognised back in 1920s, though not without its debates and dilemmas. Back in the mid 1920s, Niels Bohr and Werner Heisenberg attempted to form an interpretation of QFT that would converge with the classical kinematic and relativistic physics that were laid down by Einstein and Issac … Continue reading The Copenhagen Interpretation : Quantum Mechanics Part 2.
Credit : Design Stacks Part 1 focused on the actual speed of light in terms of a figure, 186,282 miles per second. Think about that for a second! In that second, light has travelled almost 2/3 of the way to the moon! Outrageously quick but not infinate. Our Sun is 8 light minutes away from … Continue reading Speed of Light Series Part 2 – Measuring Distance Using Light.
The time has come. The beginning of the end of our Universe. It is now 10 to the power of 14 years. Our Sun is ancient history in cosmic terms. It expanded into a Red Giant billions of years ago, swallowed the Earth and exploded in a supernova explosion. Credit : National Geographic Magazine … Continue reading The Degenerate Era – Part 2.
#astrophysics #universe #space Credit : Grand Strategy Annex From the outset of the series we have gone through the timeline of the Universe from a fraction of a second after The Big Bang to the present day. This mini series is based on the work of Fred Adams and Gregory Laughlin in their book The … Continue reading The End of The Universe – Part 1
In my last post I discussed the principles of special relativity. To recap, the speed of light is invariant for all observers in all reference frames. Special relativity tends to deal specifically for non-accelerating frames of reference, what we call an "inertial frame". General relativity is much more in depth regarding reference frames and can … Continue reading Does The Apple Fall to The Ground? Or Does the Ground and Everything on It Accelerate Upward into The Apple.
