In the Twin Paradox, the twin who travels through space at a constant velocity experiences time dilation, meaning time passes slower for them compared to the twin who remains on Earth.

Time dilation is primarily caused by velocity, particularly when an object approaches the speed of light. The faster an object moves, the slower time passes for it.

The time dilation formula is given by $t' = \frac{t}{\sqrt{1 - \frac{v^2}{c^2}}}$, where $t'$ is the time measured by the moving observer, $t$ is the time measured by a stationary observer, $v$ is the velocity of the moving observer, and $c$ is the speed of light.

As an object approaches the speed of light, its mass increases. This phenomenon is known as relativistic mass increase and is a consequence of the mass-energy equivalence principle.

The Twin Paradox was first proposed by Paul Langevin in 1911, although it was later popularized by Albert Einstein.

The Twin Paradox is a thought experiment that illustrates the concept of time dilation in special relativity.

Time dilation leads to slower aging for moving objects, not faster aging.

Time dilation causes objects to appear shorter in the direction of motion, a phenomenon known as length contraction.

Time dilation increases as the speed of light increases, approaching infinity as the speed of light is reached.

The direction of motion of the moving object does not affect the magnitude of time dilation.

Length contraction is the phenomenon where moving objects appear shorter in the direction of motion.

Length contraction causes objects to appear shorter in the direction of motion, not longer.

Time dilation slows down chemical reactions for moving objects.

Time dilation is not directly applicable to nuclear power plants.

Mass increase is the phenomenon where moving objects appear to have increased mass.
