Beyond Star Trek: Physics from Alien Invasions to the End of Time is the fourth non-fiction book by the American theoretical physicist Lawrence M. Krauss.

[1] In his previous work, The Physics of Star Trek, Lawrence Krauss explained a number of ideas and concepts featured in the series; they may or may not exist in our universe.

He uses basic Newtonian physics to show that the gravitational effects of the huge arriving alien ships would have caused floods and earthquakes sufficient to destroy our civilization before the invaders had even fired a shot.

Next, the author assesses the supposed flight characteristics of UFOs, depicted as stopping on a dime and making sudden sharp turns at utterly unbelievable speeds.

Krauss calculates that these maneuvers would create inertial G-forces greater than a close-range nuclear explosion; neither the pilots nor any conceivable construction material could withstand them.
