Time: What Is It, And, Is It Real?

"What if time is not real, but an illusion? Isaac Newton believed time was absolute and ticked at the same rate for everyone, everywhere. But Albert Einstein shattered that view with the theory of relativity. He showed that time is intertwined with space to form what we now call 'space-time.' Time can stretch and compress. 

"But physicist Carlo Rovelli proposes an even more radical idea. Rovelli argues that time might not exist at all. He suggests that time is not a fundamental feature of reality but an in invention of our brains in order to make sense of the world, to impose a cause and effect to events so they are not nonchaotic. 

"Craig Callender, a professor of philosophy, also supports this idea. The idea of time as an illusion comes from quantum mechanics. Einstein's theory of general relativity treats time as an intrinsic part of reality. But in Quantum mechanics, time isn’t malleable, and doesn’t change like other properties of a quantum system. Recording the passage of time requires an observer to consult a clock external to the quantum system."

Another Biogenesis Hypothesis

"Scientists have long speculated that life didn’t begin on Earth but in space. According to a new preprint, life could have come from intergalactic gas clouds, so-called molecular clouds."

The Probability Of Aliens On Earth

"Dr. Bryan Gillis is here to tell us why it just isn't aliens. Sorry. BUT WHAT IF IT WERE. That question too. This one is a super fun and educational deep dive into space, space travel, the Drake Equation, and more! I also get Bryan's best guess for how aliens ever COULD visit."

Space And Time 101

"What is Spacetime? Are space and time the same thing? Space was thought to be nothing, an empty void with no matter in it. In 1908, Hermann Minkowski postulated that time could be thought of as a 4th dimension along with the three dimensions of space. Einstein later showed that this spacetime is a kind of geometry that can bend, affecting the trajectory and passage of time for objects. How can space and time be part of the same canvas? Space is measured in meters, while time is measured in seconds. How are the two interchangeable?"
