Time travel: Is it possible?

Physics says time travel is possible, but probably not in the way you're thinking. Is Time Travel Possible? In short, yes—you’re already doing it, steadily moving forward in time at a rate of one second per second. Whether you’re observing paint dry or wishing for more time with an out-of-town friend, you’re continuously advancing through time at a consistent pace. However, this isn’t the type of time travel that has inspired countless science fiction stories or led to a genre with more than 400 titles listed under “Movies about Time Travel” on Wikipedia. In popular series like “Doctor Who,” “Star Trek,” and “Back to the Future,” characters enter fantastical machines to journey into the past or leap into the future. After traveling through time, they often face the consequences of altering the past or present based on knowledge from the future, which ties into concepts of parallel universes or alternate timelines. While the idea of altering the past or glimpsing the future is i...

NUCLEAR ENERGY - A Brief Overview (Part I)

Introduction Energy is one of the major constituents of our normal livelihood. We built our civilized society on the basis of pure energy resources. As an introductory fact, Energy is still a complex equation which needs to be addressed. There exists no ultimate source of energy which we can tap into, so that it remains a big concern in front of us. Ultimately we need to find a source of clean and pure energy which can fuel our aspiring needs of the future. One of the most promising and reliant sources is nuclear energy. Nuclear energy has been in development for more than 80 years, From the era of the second world war. In 1945 when the US bombed Japan in Hiroshima and Nagasaki the world saw the destructive capabilities of nuclear energy. The basic concept of nuclear energy first came into picture when Albert Einstein gave his famous mass - energy equivalence equation.Even Though he knew that there exists a possibility of a clean energy source in them,he was backlashed by it...

THE TUESDAY TOAST - S02E05

Yo peeps! We are back again with The Tuesday Toast!!! Get ready for some interesting physics facts! Give it a GO. Ever since the first Nobel Prizes were distributed, only one person has been awarded the Nobel Prize in Physics twice. The second Nobel Prize was awarded to this physicist for developing a theory which has important applications in Nuclear Magnetic resonance spectroscopy (NMR) and Magnetic resonance imaging (MRI). Name the person. Options: Werner Heisenberg John Bardeen Marie Curie Edward Mills Purcell In 1889, King Oscar II of Sweden held a competition offering a prize to anyone who would be able to give a solution to the three-body problem. A French mathematician won the competition by proving that the results of such problems are random. This discovery also gave rise to a new field of research. Identify the winner of the prize and the new field of research. Options: Leonh...
