The Speed Of Light

Time is a man made mathematical system. The Planck unit does not take into account that light speed is different in different directions. The Planck time, (tP), is the unit of time in the system of natural units known as Planck units. It is the time required for light to travel, in a vacuum, a distance of 1 Planck length, which is equal to 1.616199(97)·10^35 meters.

The speed of light is different when its moving toward us than when its moving away.

The Planck units are a man made tool to explain the speed of light that is not accurate because: (1) The speed of light is different in different directions and (2) The one way speed of light cannot be measured.

The speed of light is different when its moving toward us than when its moving away.

Einstein recognized that one-way light-travel times are stipulated rather than measured!

The one way speed of light cannot be measured.

A light beam bounced off a mirror gives an average velocity. People assume that the speed of light is the same going to a mirror as it is coming back from a mirror but it is not.

It is IMPOSSIBLE to measure the speed of the light beam coming back from the mirror.

Einstein knew this as do other physicists.

Secular astronomers assume that light travels at the same speed in all directions. Therefore they argue the cosmos must be billions of years old in order for the most distant light to have reached us.

However the cosmic background radition, a faint glow found throughout black space even when no stars shine, looks exactly like what a "big bang" explosion whould have NOT have produced!

Cosmic background radiation looks the same throughout space.

The 'big bang" theory produced "hot and cold' regions of the universe.

It would have taken these so call hot and cold spots much less time than the "big bang" theory allows.

This is a light time travel time problem in essence.

The cosmic background radiation is the same throughout the visible universe. There is no place for the "big bang" theory of hot and cold spots in the CMB radiation found in the visible universe.

Distant Starlight and the Big Bang

One of the stalwart units of astronomy just got a makeover. The International Astronomical Union, the authority on astronomical constants, has voted unanimously to redefine the astronomical unit, the conventional unit of length based on the distance between the Earth and the sun.

"The new definition is much simpler than the old one," says Sergei Klioner of the Technical University of Dresden in Germany, one of a group of scientists who worked decades toward the change, which took effect last month during an IAU meeting

Under the new definition, the astronomical unit (or AU) the measurement used for theEarth-sun distance — is no longer always in flux, depending on the length of a day and other changing factors. It is now a fixed number: 149,597,870,700 meters, which is the equivalent of almost 92.956 million miles.

Klioner explained the simpler definition is helpful, for instance, for scientists who formulate ephemerides — tables that give the precise position of astronomical objects in the sky. They utilize the astronomical unit to calculate the motion of bodies in the solar system.

The revision also makes the unit easier for engineers, software designers and students to understand, Klioner and his colleague Nicole Capitaine, of Paris Observatory, noted.

The AU Unit is less accurate now. The distance from the earth to the sun changes all the time and indeed is in "flux".

It seems to me an accurate AU Unit would be needed for some calculations that would involve a measurement of the motion of planets etc and not an fixed AU Unit that does not take into account the "flux", change in the distance from the earth to the sun, that is constantly varing.

As distance varies so does gravity that affects the motion of planets etc in the solar system. Less accurate numbers would mean less accurate calculations.

Radar reflected off the surfaces of solar system bodies can be used to accurately measure their distances as they change.

The sidereal period, the true orbital period, is the length of time required for a planet to complete one orbit as viewed by an observer from outside of the solar system, or at least from the viewpoint of an observer who is not orbiting the sun as the earth is. Since the earth orbits the sun as do the other planets, it is not possible for us to measure directly a planet’s sidereal period.
