  2. Bell's spaceship paradox - Wikipedia

    en.wikipedia.org/wiki/Bell's_spaceship_paradox

    Since the ships are moving with the same velocity in S′ before acceleration, the initial rest length in S is shortened in S′ by ′ = / due to length contraction. From the frame of S′, B starts accelerating before A and also stops accelerating before A. Due to this B will always have higher velocity than A up until the moment A is ...

    The distant boats appear to be floating in the sky as a result of looming and other refraction phenomena. While mirages are the best known atmospheric refraction phenomena, looming and similar refraction phenomena do not produce mirages. Mirages show an extra image or images of the miraged object, while looming, towering, stooping, and sinking ...

    If that fails, saving an astronaut floating off into space might require several tethers hooked together, a SAFER, and, to be honest, a lot of luck. RELATED: Here's whats happening in space this year:

  6. Space launch - Wikipedia

    en.wikipedia.org/wiki/Space_launch

    Space launch involves liftoff, when a rocket or other space launch vehicle leaves the ground, floating ship or midair aircraft at the start of a flight. Liftoff is of two main types: rocket launch (the current conventional method), and non-rocket spacelaunch (where other forms of propulsion are employed, including airbreathing jet engines).

    Hiten, Japan's first lunar probe, was moved into lunar orbit using similar insight into the nature of paths between the Earth and the Moon. Beginning in 1997, Martin Lo , Shane D. Ross , and others wrote a series of papers identifying the mathematical basis that applied the technique to the Genesis solar wind sample return , and to lunar and ...
