The concept of Panspermia is a description of all life in the Galaxy having been seeded by other life, all originating at one point. This life can hitch a ride from star to star on comets, meteorites, and rogue planets. It’s true we have never found evidence for life outside of our own home planet, but if panspermia is a viable theory, it could mean that life is everywhere, just waiting for us to find it. In a new study from astronomers as the Harvard-Smithsonian Centre for Astrophysics, panspermia creates ‘oases’ where pockets of life form. As life is able...
One of the big questions in astrophysics is about variation of the laws of Physics. The laws we know and are familiar with; angular momentum, gravity, energy, are the same everywhere on Earth. But what about beyond Earth? The universe is so large and so vast, we may be in a local region where the laws of Physics are set, and our laws may be different from a distinct region somewhere else in the universe. The good news is that we can make predictions based on our understanding of physics. And with our powerful telescopes that allow us to view a variety of...
Lurking in the depths of a galaxy, hidden from human eyes, lie millions of monsters. They could swallow you up in an instant, sealing you off from the outside world and devouring you atom by atom. This sounds like your typical Hollywood monster movie, but with millions of black holes hidden throughout the galaxy, its more real than you might think. Supermassive black holes, the largest ones that reside at the centers of galaxies, are much easier to see. They are devouring gas and dust rapidly, resulting in bright emission across the electromagnetic spectrum, especially in x-rays. For many galaxies,...
The biggest problem in theoretical physics today is the marriage between Quantum Mechanics and Gravity. Throw in the fact that whatever theory comes out of it has to additionally be able to explain Dark Matter and Dark Energy, and we have ourselves a massive problem to solve. How do we reconcile the seemingly random probabilistic nature of quantum mechanics with the smooth, pliable space-time of General Relativity. We have two incredible theories that explain the Universe, make predictions accurately, and have led to amazing advances in technology and understanding, yet they completely disagree with each other at common scales. So...
