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...

SO, WHERE ARE THE ALIENS? (PhYLenZ-1)

An Introduction to Fermi Paradox and it’s Solutions   The observable universe is 90 billion light years in diameter and is a home to about 100 billion galaxies.  Each of those galaxies is said to be home to 100 billion to 1000 billion planets. We can very confidently claim that there are trillions of planets in the universe that are habitable, so we must not be the only intelligent life in the universe right, or are we? At this point we must realize that even if there is intelligent life beyond our home galaxy, we will never be able to find them or communicate with them, since it would take us billions of years to reach another galaxy even at the speed of light. Therefore, let us focus on our immediate galactic neighborhood i.e. the Milky way. The Milky way has an approximate of 20 billion sun-like stars harboring their own solar system, about 1/5 th of these solar systems have a planet in the habitable zone, which equals 4 billion habitable planets. Considering that the Milk...
