The book is still considered influential in the physics community, with generally positive reviews, but with some criticism of the book's length and presentation style. To quote Ed Ehrlich: [4] 'Gravitation' is such a prominent book on relativity that the initials of its authors MTW can be used by other books on relativity without explanation.
Steele said "V-S Day" first began as a novelette, "Operation Blue Horizon", which was published in 1988. The idea for the story came while researching his first book, Orbital Decay (1989) when he stumbled onto references to Sänger's space bomber. Steele stated that he "wasn't completely satisfied" with "Operation Blue Horizon" and rewrote it.
SF Crowsnest wrote that "overall, 'Spindrift' is a very solid novel but not as essential as the first couple of 'Coyote' books." [ 5 ] BookReporter.com praised Spindrift , calling it "a fill-in, but it is worthy mortar in the monument of Steele's great future-history epic about daring deep space exploration and world-building."
In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction primarily observed as mutual attraction between all things that have mass.Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force and 10 29 times weaker than the weak interaction.
General relativity is a theory of gravitation developed by Albert Einstein between 1907 and 1915. The theory of general relativity says that the observed gravitational effect between masses results from their warping of spacetime.

The weight of an object on Earth's surface is the downwards force on that object, given by Newton's second law of motion, or F = m a (force = mass × acceleration). Gravitational acceleration contributes to the total gravity acceleration, but other factors, such as the rotation of Earth, also contribute, and, therefore, affect the weight of the ...
[7] [8] [9] The Watt–Misner theory (1999) is a recent example of a scalar theory of gravitation. It is not intended as a viable theory of gravitation (since, as Watt and Misner point out, it is not consistent with observation), but as a toy theory which can be useful in testing numerical relativity schemes. It also has pedagogical value. [10]
