Reply to [Story] I have 48 days to fix my life by itslexibicth

You may just discover resilience in you that you do not know you have. Don't overthink it. I have heard people say to follow your feet, where the body goes, the mind will follow.

Make a routine that starts with an early morning shower and forward momentum. It will be difficult, but it will not break you.

Reply to Is the yearly cycle of varying daylight durations from day to day throughout time consistent? Is the cycle we have today the same as in the 17th century? by meellowstar

Although keeping time is a human invention and was only agreed upon relatively recently, variations in the earth's wobble around its axis have lead to shorter and longer amounts of sunlight further away from the equator.

But these variations are part of a long cycle (Milankovitch cycles) on observatories like Newgrange and Stonehenge prove that the position of the sun in the northern hemisphere has been very consistent for the last 10,000 or so years.

Reply to has the speed of light always been constant? by 2bornnot2b

The speed of light can be calculated using the vacuum permittivity ε0 and vacuum permeability μ0 established by Maxwell's theory: c2 = 1/(ε0μ0).

Einstein used this fact to show that the speed of light in a vacuum must be constant in every inertial frame, thus relative.

Because permittivity and permeability are constant in electromagnetic theory, c must have always been c.
