Force makes things possible. Behind every phenomenon, there is a force and according to modern science, there are four unique forces which makes everything in the Universe possible. But, different anomalies in experiments and incomprehensible things present in the Universe suggests there might be room for a fifth force or maybe more. The Need of Fifth Force in Modern Science Our knowledge is evolving. We are discerning the truths one by one. But, we’ll never hit the rock bottom in this abyss of knowledge. There is more, always there is. When it comes to scrutinizing the cosmos, the former sentence…

Stars are the most massive objects in the Universe. When such a massive star vanishes without a trace, it is likely to create a fuss in the scientific world. A paper published on Royal Astronomical Society reports that a massive star in a galaxy called PHL 293B vanished without a trace. A team led by PhD student Andrew Allan of Trinity College, Dublin, Ireland were not able to find any signs of the star when they attempted to observe it using Very Large Telescope. If correct, this is likely to be the first-ever such observation. Generally, such massive stars get…

Protons, electrons and neutrons are the major constituents of an atom. There are thousands of varieties of atoms and each has different sets of those above-mentioned particles, the number of constituents is what defines them. Find Number of Protons, Electrons and Neutrons Number of Protons Protons are positive charge carriers, each has positive 1.6*10^-19 coulomb charge and mass 1.673*10^-24 grams. The number of protons in an atom also called atomic number is different for different elements, the same element has the same number of protons in their atoms. It is represented by Z. Whenever someone says carbon, you can precisely…

According to Einstein’s special theory of relativity, nothing can travel faster than light. But was Einstein correct? Can we even dare to doubt his conclusions?  Is there anything that can travel faster than light? Can faster than light phenomena be used in our daily life? What is Quantum Entanglement? And how can this relate to the speed of light? Is It Possible To Communicate Faster Than Light? Yes, it is possible and the technology is in its infancy. And it is due to a phenomenon called quantum entanglement. What is Quantum entanglement? Quantum is a luscious word for physicists; it…

Science has seen an ample amount of advances in October. Here is our monthly round-up science news and updates for October. 1. 2020 Nobel prize in STEM This month Nobel prize was announced. Here are the winners of 2020 Nobel prize in the STEM field. Physics Nobel prize in Physics 2020 was jointly awarded to Roger Penrose (half) for the discovery that black hole formation is a robust prediction of the general theory of relativity, Reinhard Genzel (one fourth) and Andrea Ghez (One fourth) for the discovery of a supermassive compact object at the centre of our galaxy. – Source…

Protons, electrons and neutrons are the main constituents of an atom. Every form of matter is a combination of fixed numbers of these constituents. So, for understanding matter world, we must know the number of protons, electrons and neutrons in an atom and its significance. How to Find the Number of Protons, Electrons and Neutrons in an Atom? These three sub-atomic particles are responsible for almost all the properties of an atom. Also, a change in the number of these particles in an atom may give rise to a new atom or introduces a new form of the same atom.…

Round-Up: Monthly Science News and Updates September 2020 Science is progressing as each second in our clock pass by. Here is our list of monthly science News and Updates for September 2020. 1. Quantum Computer Solving Real-life Problems Quantum computers have been admired for long but were not used to solve real-life problems. Google AI quantum and collaborators were able to run a molecular simulation on Google’s quantum processor Sycamore. They used variational quantum eigensolver (VQE) algorithm to simulate the binding energy of hydrogen chains and isomerism mechanism of diazene. The accuracy of the calculations was reliable and this could…

We are all enslaved to time. Even if we do nothing, we are spending time. And, time is a mystery. But, physics states that time as we perceive it is an illusion. The concept of the illusion of time is explicit from a relativistic point of view. Time is constantly moving towards the future. Even if you stop, the time won’t. Things are ageing and everyone is. I bet there is not a single person in this world who has not thought of stopping this monotony of time. Everyone wants to escape from this bondage. On this quest to solve…

The pace of research and discovery may have dropped due to COVID-19 but still, discoveries are being made and August 2020 was not different. Here is the monthly science news of August 2020. Science News Monthly – July 2020 1. Ultra-fast, cheap COVID19 test Testing is the major weapon in this fight against COVID19. Testing assures the safety of people from the virus by detecting the ones who have it. But, even in a country like the United States, the average waiting time for COVID19 test results is 4.1 days. Although there has been development in other rapid testing, the…

A black hole is a mystery. It is a singularity where mathematical values of time and space are undefined. Modern science is mute within that point. So, everything that happens inside the black hole is beyond ordinary. We listed here 5 extraordinary things that happen inside the black hole. 5 Extraordinary Things That Happens Inside The Black Hole 1. Time Freezes – No Past or Present or Future Ever since the theory of relativity was published, the concept of time has changed. Time does not pass uniformly everywhere. According to gravitational time dilation, strong gravitational fields set up by massive…
