The speed of light is derived from general relativity. A meter is defined as the distance light travels in some fraction of a second, and a second is derived from quantum energy equations.

OK, I took your advice Master, and looked up the definitions of the speed of light, the meter, the second, and even Vacuum.

The post by Phaedrus is not at all accurate, although you sure seem to get a charge out of him "schooling" me.

Here is what I found according to Wiki:

The Speed of Light:

The Meter:

The Second:

and the condition of Vacuum:

So, the supposedly unsahakable bedrock upon which all currently accepted views of the universe are based- "The Speed of Light" is defined by using the Meter and the Second- in a Particular condition : Vacuum.

Next, what is a Meter? It is defined using the Speed of Light and the Second in a Vacuum.

Hold on here, these two definitions rely on eachother to define themselves. This is not valid. Surely then the Second must be the lynchpin that holds these definitions together, right?

Nope. The Second is defined using measurements of "periods of radiation(travelling at the speed of light) of a substance ,whose properties are defined using Mass and Specific Gravity- both of which require both the Meter and the Speed of Light to derive, in a Vacuum.

Next, all of these definitons rely on measurements within an admittedly impossible condiditon- a complete Vacuum.

SO:

The Speed of Light is defined by using the Meter and the Second.

The Meter is defined by using the Speed of Light and the Second.

The Second is defined using The Speed of Light and the Meter.

And all of these definitions are supposedly based by taking these measurements in a condition that is admitted to be impossible.

This is clearly Circular Reasoning . None of these things are proven. This means that the currently accepted "mainstream" views of the entire Universe are based purely on Assumptions .

Thanks for the "Schooling"

The Speed of Light:

Quote:

The speed of light (meaning speed of light in vacuum), usually denoted by c, is a physical constant important in many areas of physics. Its value is 299,792,458 metres per second, a figure that is exact since the length of the metre is defined from this constant and the international standard for time |

Quote:

The metre (or meter), symbol m, is the base unit of length in the International System of Units (SI). Originally intended to be one ten-millionth of the distance from the Earth's equator to the North Pole (at sea level), its definition has been periodically refined to reflect growing knowledge of metrology. Since 1983, it is defined as the length of the path travelled by light in vacuum in 1⁄299,792,458 of a second. |

Quote:

The second (SI symbol: s), sometimes abbreviated sec., is a unit of measurement of time, and is the International System of Units (SI) base unit of time.[1] It may be measured using a clock. Early definitions of the second were based on the apparent motion of the sun around the earth.[2] The solar day was divided into 24 hours, each of which contained 60 minutes of 60 seconds each, so the second was 1⁄86 400 of the mean solar day. However, 19th- and 20th century astronomical observations revealed that this average time is lengthening, and thus the sun/earth motion is no longer considered a suitable basis for definition. With the advent of atomic clocks, it became feasible to define the second based on fundamental properties of nature. Since 1967, the second has been defined to be the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom. |

Quote:

vacuum is a volume of space that is essentially empty of matter, such that its gaseous pressure is much less than atmospheric pressure.[1] The word comes from the Latin term for "empty". A perfect vacuum would be one with no particles in it at all, which is impossible to achieve in practice |

Next, what is a Meter? It is defined using the Speed of Light and the Second in a Vacuum.
