Does a Foucault pendulum move quicker above than below of the apparatus?

Time period is considered to be slower at low altitude than at high altitude. Does a Foucault pendulum move quicker above than below of the apparatus because of gravitational time dilation?

What about absolute simultaneity of the sky (since million years for example)?

Since experimental evidence, it is well known that a desynchronization of clocks appears between different altitudes on earth (simultaneity is relative). However, simultaneity (absolute for the...

Does a new view of aberration of light solve galilean relativity?

Dear folllowers, Imagine you are in 1905, where experiments known today were not done. Does aberration of light exist for a source horizontal to a moving frame? Such a phenomenon (which...

Does a rotating disk (inside the frame) turn slower than an unrolling coil followed by a moving observer?

Imagine a frame A (ground) unrolling a coil at speed ~c. Imagine a second frame B (moving rectiline) following the coil and turning next to it a disk at same speed. If both are supposed to turn at...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...
