It’s not gravity which distorts Space-Time. The bending or distortion of space-time is due to the mass. If there is more mass, more will be the distortion. Einstein’s Theory says Gravity is not a force. But a manifestation of Spacetime curve. If Space-time is flat, means so-called Euclidean and that geometry is called Minkowski. There is no Gravity, no mass at all. or if there is a mass the mass is so small, like an atomic scale. In atomic scale the Space-Time is flat. There is no effect of gravity on that scale. What we best do is neglect the potential due to gravity, because it’s magnitude is so small than any other interactive force like Electromagnetic, Nuclear interaction. By using the Space-time idea, people have construed Relativistic QM. But due to so much mathematical inconsistency, this theory is no longer valid.  People have evaluated more advance theory like  QFT  (Quantum field theory), Which is consistent with Einstein’s special theory of relativity.

TIME MYTH B efore coming to home I was thinking about home being only consumed by my studies. I stimulated so many simulations about this. That was all theoretical. In imagination things are awesome but in reality, things are hell different. Expectation before coming home . Ø Study Round O clock because in home I have separate room and nobody is there to disturb me. Ø I will learn to program for Mathematica and Matlab. Ø I won’t see the movie and use lapy as it actually for, not for just time pass. Ø In IIT I don’t get too much free time study different books, so I will spend my most of the time studying books. Ø I will finish Quantum Field Theory and General Relativity . And I will do some projects of MIT. Ø I will see lectures . Ø I will spend my time writing answers on Quora. Ø Speak less and don’t act like a kid. Ø Avoid every controversial scenario and statements. Involve yourself only in Physics completely. Ø Be less social and focus more on

To Do Research like Einstein one needs to upgrade his Brain. Ø Why it’s needed to upgrade the brain? It’s a nice question and let me answer this in this way… once I was playing some games.  I was trying so hard to win that game. I tried each possibilities but still I was not enough to compete my opponent. Its demands only upgradation. I finally upgrade my ingredient and compete the opponent. I then realized that, that’s the approximate same thing also happens in my real life. I try so hard to understand physics, solving problems, but still I am nowhere. That really sucks. What to do? I thought that upgradation may be the key to handle this problem. Since I study hard, but still there are lots of problem which is out of reach from my level of understanding. Neither, I can think how to solve the mysterious problem of world. If I want to solve these problems I need more mathematical and physical knowledge and different ideas, which I am completely lack of. I can’t even solve

AN INTERVIEW WITH TACHYON DISCOVERER Eminent scientist E.C. George Sudarshan on growing up in Kerala, his tryst with physics and on the state of research in India The physicist Hans Bethe once said, “There are two types of genius. Ordinary geniuses do great things, but they leave you room to believe that you could do the same if only you worked hard enough. Then there are magicians, and you can have no idea how they do it.” In the world of science, every so often we come across visionaries, ‘magicians’ in the words of Bethe, who dare to perceive the world in ways no one else has before. E.C. George Sudarshan is one of them. From formulating fundamental ideas in particle physics to understanding the quantum nature of light, Dr. Sudarshan’s contributions to physics read like a fascinating chapter from the book of breakthroughs in the science of the past century. Born in Kottayam in 1931, E C G Dr. Sudarshan studied at the CMS College and later at the Madras Christian Col

MIT Theoretical particle physicist Jesse Thaler was a high school student in 1995 when a pivotal discovery in science turned his life’s path toward particle physics. That year, physicists at the Fermi National Accelerator Laboratory confirmed that its Tevatron particle accelerator had detected, for the first time, a subatomic particle known as the top quark. This article had been a missing piece in the Standard Model of particle physics — a theory that describes all the known elementary particles and several majors, fundamental forces governing the universe. “I remember my physics teacher had a big poster of the Standard Model on the wall, with a question mark next to the top quark,” says Thaler, who recently was granted tenure as an associate professor in MIT’s Department of Physics. “When it was discovered, I remember him writing down the mass of that top quark where there used to be a question mark. I thought discoveries must happen all the time. Little did I know that part

Albert Einstein is singular.           – Lee Smolin, When I study the papers of other great physicists, such as Galileo, Kepler, Maxwell, Bohr, Heisenberg, Schrödinger, and Dirac, I can understand who they are. They are extremely good scientists, but not different, in kind, from the best of my contemporaries. Einstein is different. (Newton is also different, but they are the only two.) After many years of study, I still find Einstein’s unerring, surefooted ability to penetrate right to the heart of things to uncover the secrets of nature incomprehensible. How did he do it? What makes Einstein different from the rest of us? What made him different from his contemporaries, and allowed him to make discoveries that others couldn’t? With hesitancy, due to my appreciation of the subtlety of his thought, here is a tentative answer: Einstein was a storyteller. Einstein asked different questions than his contemporaries. They were content to live with the knowledge that was incomplete

TO BECOME THEORETICAL PHYSICS FIRST YOU NEED TO GET RID OF SOME PARTICULAR HABITS. THESE HABITS ARE OBSTACLE TO BECOME ANY THING… PROCRASTINATION DON’T SEEK FOR HIGH GRADES ALWAYS QUESTION LIKE HOW TO BECOME THIS ONE OR THAT ONE, HOW TO SOLVE PROBLEM AND SO ON.  NEVER LET YOUR SELF DEMOTIVATED WITH THE FAILURES YOU WILL RECEIVE IN THIS PATH. DON’T FOLLOW MATHEMATICS BLINDLY. INDIAN AUTHORS THEY JUST WRITE MATHS AND NEVER LET YOU THINK THAT WHAT THE CORE THINKING BEHIND THIS...IS  NEVER FILL YOUR HEAD WITH BULLSHITS. THESE THOUGHTS GONNA EMBRACE YOU AND MAKE YOU FEEL LIKE HELL. DON’T TRY TO BECOME LIKE A.EINSTEIN OR FEYNMAN, NEWTON AND SO ON. YOU NEED TO FIRST UNDERSTAND THAT ALL GREAT PEOPLE ARE DIFFERENT FROM ONE ANOTHER. THEY NEVER COPIED SOME ONE ELSE’S LIFE. MEANING THAT DON’T TRY TO BECOME SOME ONE ELSE RATHER BECOME ORIGINAL. DON’T SPEND TOO MUCH TIME ON SOCIAL NETWORKING. ALWAYS READ BOOKS. ALWAYS DO MATHEMATICS AS MUCH AS YOU CAN. IN THEORETICAL PHYSICS THERE AR
