Dark energy makes up about 70% of our universe, but we had no clue of its existence till 1998. Today, we know it does exist but very little about its nature or origin is known. This gives way to various theories attempting to model this energy and find out the consequences it has for our […]

Recently during December-January, the world saw greatest rise in the value of Bitcoin. One bitcoin had hit its highest i.e., ₹32,58,664 on 8th January 2021. Sometime back in 2008, its value was almost zero. It reached $1 in 2011. You can imagine, if a person would have deposited around Rs ₹100 sometime in 2011 then […]

Dark energy is a much heard but little known topic. Read on to know what dark energy is and what happens as it takes on gravity as well as the energy from the big bang simultaneously. The Big Bang A fiery burst of energy in the middle of nowhere out of virtually nothing created our […]

CP Symmetry ( Charge Parity and Symmetry Parity) problem is one of the greatest mysteries of physics. The standard model of physics predicts that matter and anti-matter should have annihilated each other until nothing remained. Yet the universe exists in all it’s grandeur as is evident with the first breath you take. Humans judge beauty […]

Scientific Nation presents to you the History of medicine and medical science practices. From Egypt to India and from Penicillin to Covid-19 vaccine. The humans have witnessed all. Medical Sciences are a necessity, so it needs a progression. For, this progression there is a need for an understanding of the history of medicine and the […]

Anti-particles are particle alter-egos. When they meet they annihilate each other to give a fiery burst of energy. Just after the Big Bang the particles and antiparticles should have met and the universe should have ended but we exist. Read on to find out how. An Universe-gobbling Mistake What will happen if you take ten […]

Let’s get back to the question we started this series with. How do you see something that weighs nothing, looks like nothing and interacts with nothing? The answer is that it does weigh a little. So little is their mass, that for a long time neutrinos were thought to be mass less. Now we know […]

At 7:35 am UTC on February 23, 1987, the Kamiokande II detector in Japan suddenly detected more than 10 anti-neutrinos. It was designed to detect proton decay, so this was not a regular event at the detector, and scientists were alarmed (It was confirmed by proton decay detectors in the US and Russia). Then a […]

The Strange Ghost. Have you ever imagined a ghost-like thing passing through your body without ever being noticed by you? There are trillions of particles that pass through your body and you never know it in your lifetime. You might have heard about atoms in school days, probably you might have also heard about Electron, […]
