“Let’s Ponder” by Satya Prakash Verma is the second edition of the book named “Mysteries of the Universe – Unveiled,” published in 2015 through M/S Partridge Publications, India.

Although the market is flooded with different books on Astrophysics, this book is much different from all of them; this book is neither a Science-Fiction nor a Research-Paper that is based on the Mainstream Science; this book is, in fact, a Disquisition in which the Prominent Theories of mainstream science have been very boldly analyzed, and their probable Limitations have been logically explored.

Since this book has been written to convey the message that our scientific theories might contain a few loose ends, the first part describes the circumstances under which shortcomings are likely to creep into any theory. In the following two parts, the author has first very boldly described the alternate angle of some of the modern scientific theories, in brief, portraying some of the probable loose ends that might exist in the eminent theories that are supposed to govern the functioning of the universe; these theories are: - the Wave Theory, the Theory of Relativity, Quantum Mechanics, String Theory, Theory of Gravity, the Big-Bang Theory and the Standard Model of Particle Physics, etc. Next, based on the alternate angle disclosed herein, an altogether new perspective on the creation of the galaxies, stars, and their planets, etc., has been presented; this part also sheds light on some of the mysteries that hitherto remained unresolved.

This book also discloses his idea to carry out the experiment to determine the unidirectional speed of a light-beam. Though this experiment is considered impossible to perform by many, he has shared an idea by which this experiment may possibly be conducted successfully. In case the light is found to propagate with different speeds in the direction of the Earth’s motion and in the direction opposite of it, then it could be inferred:
1) Neither the distances contracts nor the time dilates at the speed of light.
2) Light does not necessarily propagate in waves, i.e., it is not necessarily a disturbance created in any medium; because a similar result would also be obtained even in case light travels in the form of a shower of particles that vibrate at different frequencies.

The author’s main aim in writing such a book is to spread the idea worldwide that time has now come to review our eminent scientific theories and modify them if felt necessary.
