Gravitational Anomaly.

Gravitational Anomaly: (asked by a student for very simple explanation)

Basically it means the new laws of physics known as Quantum Mechanics invalidates the sanctity of nature’s principles or laws (that is QM brings exceptions to the validity of the physical laws of nature itself)

Let us discuss this in simpler ideas from the basics only.

Remember the most basic physics, that of principle of conservation of energy and the principle of conservation of (linear) momentum.

In the more rigorous formalism of physics these two principles emanate (that is derivable) from two ideas of symmetry. In-fact every conservation principle of physics are manifestations of a corresponding principle of symmetry and vice-a-versa (also every symmetry must correspond to a conservation law). This general idea of connection between conservation laws and symmetry is collectively known as Noether’s theorem and is a central underpinning in all of today’s conceptual physics.

LIGO in India? You must be kidding …

I was pleasantly surprised that this experiment is slated to come up in India, yes, with a whopping 250 million dollars investment into science in India is perhaps the only 2nd instance of massive science euphoria.

And they are both directly or immediately so, in my field of research, although the first one INO isn’t seeming to be coming of age, while collaborations and Physics and engineering as such have been extensively laid out in the ground, the lab the much coveted international particle physics lab that is, hasn’t come.

(Surprise me, if work has already begun in Madurai, we have been struck by paranoia of environment so much that the elephants have the right of way more than the most innocuous science commies out there, pardon me, that’s a pun, no disrespect to elephants, no offense to commies.)
