Vast Space is a private company that proposes to build the world's first artificial gravity space station using the rotating spacecraft concept. [23] A Mars gravity simulator could be built on the Moon to prepare for Mars missions. The surface gravity of Mars is somewhat more than twice that of the Moon.
Objects are falling to the floor because the room is aboard a rocket in space, which is accelerating at 9.81 m/s 2, the standard gravity on Earth, and is far from any source of gravity. The objects are being pulled towards the floor by the same "inertial force" that presses the driver of an accelerating car into the back of their seat.
If the near-light-speed space craft is interacting with matter that is moving slowly in the planetary reference frame, this will cause drag which will bleed off a portion of the engine's acceleration. A second big issue facing ships using constant acceleration for interstellar travel is colliding with matter and radiation while en route.

He published a Lorentz invariant theory on four-dimensional spacetime, where gravity is transmitted by gravitational waves that travel at the speed of light. As Einstein later said, the reason for the development of general relativity was the preference of inertial motion within special relativity , while a theory which from the outset prefers ...
Maximum speed is finite: No physical object, message or field line can travel faster than the speed of light in vacuum. The effect of gravity can only travel through space at the speed of light, not faster or instantaneously. Mass–energy equivalence: E = mc 2, energy and mass are equivalent and transmutable.

A space suit helmet featured in the film. Kubrick consulted aerospace specialists to ensure the design's accuracy. The general approach to how space travel is engineered is highly accurate; in particular, the design of the ships was based on actual engineering considerations rather than attempts to look aesthetically "futuristic".
