The idea that everything is connected has always been comforting. For one, this says that we are not alone and that our short lives could actually be more meaningful as it is. Fancy enough, the same is true in physics, which is, in its purest form, the science of the most fundamental interactions.
So, welcome to my website, the primary purpose of which is to serve as a platform to transparently communicate scientific results to students and professionals. With this said, please always feel free to checkout the research section to download and use my notebooks as well as to send a friendly message for questions, if any.
On this first (and only!) blog post, as is well known, noninteracting particles don't exist. Otherwise, basketball wouldn't be so exciting if objects aren't (gravitationally) attracted to the ground and neither would we be enjoying the light from the Sun as the earth orbits around it. At least, at some point in time, every piece of the Universe would have to interact with others, and by doing so they stray away from straight line motion. The contents of a closed system, such is the case for our Universe, interact thermodynamically to conserve energy. The interactions that we perceive are all just manifestations of this.
Indeed, "Pick a flower on Earth and you move the farthest star." (Paul Dirac). Physics could not be simpler and more romantic.
These words beautifully capture the essence of an interconnected universe. It reassures us of our connection to the rest of the cosmos. How deeply we can explore this intimate connection is the subject of physics. Perhaps, all of us are entangled, even to the contents of a black hole, aka, a collapsed star. Some day we'll find out. But today, we make peace with the theories of quantum mechanics and general relativity, among many other scientific accomplishments.
Quite remarkably, with all the technological breakthroughs in astronomy today, thanks to a bunch of gravitational wave and cosmological surveys in action, we could now even hear the calls from the farthest of stars, and even the retired ones, black holes. Later, we may probably even hear the sounds from the big bang itself, the explosion that created everything. Tapping into this power, we are one gravitational wave-phone call away from the rest of the dark Universe. How long could it be before we move stars?
Have a great day!
