The principles on which special relativity are based include all the following EXCEPT Only the universal rest frame gives correct measurements. An observer in an inertial reference frame cannot tell if they are in motion or not. The laws describing observed motion are the same in any inertial reference frame. The speed of light is the same in any frame of reference. Observers in two inertial frames agree on the speed of the other observer.

Time Dilation Time Dilation is a relativistic effect where time measured in two reference frames with relative motion is different, even when the clocks in both reference frames are initially synchronized. Clocks are synchronized when the same time is measured when their inertial reference frames are at rest relative to one another (meaning there is no relative velocity). When t0, the clocks in the two reference frames are synchronized at the origin. The Proper Time (To) is the time difference...

A spaceship is moving past Earth at 0.99c. The spaceship fires two lasers. Laser A is in the same direction it is traveling, and Laser B is in the opposite direction. How fast will the light from each laser be traveling according to an observer on Earth? Select one: a. The light from Laser A will be traveling at 1.99c, the light from Laser B at 0.010 b. The light from Laser A will be traveling at c, the light...

Question I need answered is bold faced here:
Relativistic Mass Still standing in the same spaceship... With
respect to an observer in a given frame of reference, how fast
would the spaceship have to move in order for your [moving] mass to
be double your resting mass? From your perspective, what
will be your mass on board the spaceship? In the last two weeks we
have investigated time, length, and mass at very high velocities.
