I’m thrilled to introduce Dr. Boris Goncharov, a distinguished figure in the field of gravitational wave research. Currently, he is a Senior Scientist with the Pulsar Timing Array (PTA) group at the Albert Einstein Institute (AEI) in Hanover, Germany, where he is exploring the fascinating world of nanohertz-frequency gravitational waves.
When we talk about the fabric of reality, in terms of physics, we deal with interesting abstractions and tonnes of complexities. One such intriguing concept of Einstein’s theory of general relativity is the existence of gravitational waves. As the name suggests, these ripples are generated in the spacetime by some of the universe’s most violent and energetic processes, such as mergers of cosmic stars or dent in the landscape due to black holes. Interestingly, whenever these waves pass through, they leave a measurable imprint on the relative positions of objects—a…
Detecting gravitational waves have always been a challenging task. It is caused due to high energetic events, like colliding black holes or neutron stars. And so, the phenomenon is like ripples on the fabric of space-time. By the time, this effect reaches us (from deep space), the signals become extremely weak. And hence, too faint to detect.
Michael White and Dr John Gribbin, adept science writers, have masterfully depicted an indomitable genius and an expansive scientific intellect in the book – Stephen Hawking: A Life in Science. It was first published in 1992. As I read the pages of this book, I’m struck by how the writers effortlessly blend clear explanations of Hawking’s scientific achievements with a heartfelt account of his personal life. Their approach allows readers like me to gain a deeper understanding and appreciation for both facets of his remarkable journey. The book recounts how…
I am honored to introduce Professor Roberto Maiolino, an esteemed figure in the field of Experimental Astrophysics. Currently holding the position of Professor at the Department of Physics (Cavendish Laboratory) and the Kavli Institute for Cosmology, University of Cambridge, Dr. Maiolino also serves as an Honorary Professor at University College London and holds the prestigious title of Royal Society Research Professor. With a primary focus on the exploration of galaxy formation and the evolution of supermassive black holes, Professor Maiolino employs a diverse array of observing facilities to unravel the…
“The Trouble with Physics: The Rise of String Theory, the Fall of a Science, and What Comes Next” by the theoretical physicist Lee Smolin delves into the history of physics, starting from Copernicus. The book also explores the contemporary state of physics research. It was written in 2006, and at that time, string theory had significant influence in the field.
Dr. Ore Gottlieb is a theoretical high energy astrophysicist. Currently, he is occupying Rothschild/CIERA Postdoctoral Fellowship position in Astrophysics at Northwestern University. His recent work on “Dying stars’ cocoons could be new source of gravitational waves” caught our attention and so we tried to touch base with him for an interview. We got lucky, as he agreed to spend some time with us.
Gravitational waves are ripples in the fabric of spacetime caused by the acceleration of massive objects. The main source of detecting gravitational waves are the mergers of binary systems consisting of black holes and neutron stars. Till now, the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo detector have successfully identified gravitational waves.
According to Einstein’s theory of general relativity, gravity arises from the curvature of spacetime, caused by the presence of massive objects. This curvature, also, impacts the motion of all nearby objects thus, causing them to move in curved paths. General relativity however breaks down under extreme conditions such as those found in black holes and the early universe. These conditions comprise of high energies and densities, which exponentially influences the effects of quantum mechanics. And it has been observed that the laws of general relativity no longer provide a complete…
Dr. Arthur Suvorov is an astrophysicist at The Manly Astrophysics in Australia. He did first class honors degree at Monash University, in a double-dose of mathematics with physics on the side. Followed by his PhD from Melbourne Uni. His areas of interest include various aspects of neutron star. Lately, he collaborated with Universidad de Murcia, Spain in a project entitled “Magnetically supramassive neutron stars”, paper of which is also published in Physical Review Letters (DOI: 10.1103/PhysRevD.105.L061302). Dr. Suvorov is also the recipient of one of the most prestigious Humboldt…
Dr. Michio Kaku is a well-known figure in science academia. He is a master story teller. His super power is, he can make science graspable for non-science people like myself. In The God Equation: The Quest for a Theory of Everything, Dr. Kaku talks about three things: physics from creation to present, the effort put behind in unifying all known physical forces and the theory of dimensions, string theory.
Dr Benjamin Pope is a physicist and data scientist at The University of Queensland, Brisbane. He is working to find planets around other stars using NASA space telescopes. With the help of leading-edge machine-learning algorithms, he is trying to dig up tiny signals out of the noise to expand our knowledge of the universe.
In a collaborative effort, an international team of astronomers at The University of Queensland and the Dutch national observatory ASTRON have been looking for planets with the help of the most powerful radio telescope – Low Frequency Array (LOFAR) – located in the Netherlands. Recently, they were able to figure out stars spewing off radio waves. This hints at the presence of some hidden planets.
The Fabric of the Cosmos: Space, Time, and the Texture of Reality is the second book of theoretical physicist, mathematician, and string theorist, professor Brian Greene. However, this happens to be my third read from the author, first two were Until the End of Time and The Hidden Reality.
Dark matter is one of the key ingredients in the understanding of evolution and in the formation of galaxies. Majority of scientists are of the view that dark matter consists of weakly interacting massive particles (WIMP). It is because of their weak interactions with matter that we see around, it becomes extremely difficult to detect.
