We thought that the C14 radiocarbon method will give us the independent irrefutable dating of objects, but it doesn’t because the historians have smuggled therein their erroneous chronology. To make matters worse we have made thousands of nuclear explosions that have distorted the picture.
We have the remnants of a Supernova explosion called the Crab Nebula that shone for a couple of months above our heads about 1000 years ago. Alas, the date of this Bang is approximate, AKA +/- 100 years calculated on the basis of changes in photographs for the last 150 years.

Astronomy is precise by definition, therefore if a date can be calculated from the irrefutable, verifiable, and independent information contained and extracted in the event, it is considered true.

The date of such an event may serve as the origin of coordinates to fix historical events to their more probable positions on the time axis. The sky provides us with such a visible phenomenon.

The astronomers found the exact date of the explosion of the Crab Nebula Supernova in XII century A.D. in the Taurus constellation by calculating its expansion speed by comparing its photographs taken from 1844 to 2018.

Dozens of ‘ancient’ learned chroniclers and astronomers report about the appearance of very a bright star approximately 1000 years ago. These reports are often conflicting as they used real or an imaginary phenomenon in the sky to stress their local events.

Corollary A: an irrefutable astronomical phenomenon itself serves as the reference point for the dating of historical events and not the dates of astronomical events found in chronicles of refutable dates and/or origin.

Corollary B: taking into account the irrefutable events only, confirmed by exact sciences the true timeframe of human history does not exceed 1000 years. All ‘ancient’ histories are ‘on agenda’ produce of XVI-XXVIII centuries.

Corollary C: the explosion of the Crab Nebula Supernova is a reference point for datings events on the time axis. Today we are in 966, not in 2020 AD.
