I think that if one were to go with the strict definition of the word "carve" - meaning "to make something by cutting into especially wood or stone, or to cut into the surface of stone, wood" - then it is fine. However, as I mentioned before, "carve" can have an association with art within a common psyche, i.e. carving a statue, or carving a wooded totem pole, and s

The Historic England website has a nice 3D laser scanned model of the wood, as well as an archaeological illustration in which you can see the "intentional cut-marks".
And I think this "intentional cut-marks", is an important phrasing since the word "carving" can conjure up the connotation of creative art. It could well be that the cut marks were purely dec

The article is an interesting read, and highlights the need for future iterations of the radiocarbon calibration curves to incorporate more single year measurements. Indeed, one is almost getting the sense that IntCal13 (and prior curves) may systematically be giving older calibrated radiocarbon dates for a lot of the curve, whilst IntCal20 seems to be giving more accurate calibrations particula

What is becoming more clear is that the claimed directionality of the debris flow (originally claimed to be in a north easterly direction), is not supported by the newly provided images in which the site arrow (which indicates north) has been restored. See posts 19 and 34 in the site.

It's the square root in all cases.
2D R = sqrt(a^2+b^2)
3D R = sqrt(a^2 +b^2 + c^2)
4D R = sqrt(a^2 + b^2 +c^2 + d^2)
ND R = sqrt(a^2 + b^2 +c^2 + d^2 + .... + N^2)
The reason is because it is essential Pythagoras Theorem C^2 = A^2 + B^2, but extended into higher dimensions.
If we put that into units of metres for example, then all quantities are in square metres, and so ta

I think that the the reason for just two universes is because there appears to be only one single dimension of time, in which "Movement" can only occur within (forward and backwards). This is analogous to spacial dimensions, of which we can detect only three of, where an objects position or movement is defined with respect to each of those dimensions. For example, if we call each of t

The weakening and disappearance of the magnetic field on Mars was due primarily to the planet's size. A planetary magnetic field is created by a dynamo effect of molten metal sloshing around near to the core of the planet. This molten metal creates a current, and a moving current generates a magnetic field. However, because Mars is small, it's core cooled quickly (much quicker than E

Colavito concludes on his blog
Quote Regardless of the authors’ correctness on the source of the meteoric fragments, their conclusion cannot be correct because the Hopewell did not enter a terminal decline after their proposed impact date of c. 255-300 CE but flourished for another 200 years.
First thing of note is that Colavito has truncated the calibrated radiocarbon dates for the apparen

If the logs are indeed radial, then one could probably take a core sample and do a radiocarbon wiggle match, to get a more precise felling date for the logs.
However, there would be an issue with this that is inherent with the unfortunate shape of the radiocarbon calibration curve at the time of the Old Kingdom. The issue is that there is a so-called radiocarbon plateau at this point in time.

Unfortunately, the only true way of ascertaining where the position of wood (be it a small item, or a large item), is find bark or sapwood, in which case we can say for certain that it came from the outer portions of the tree. However, in theory, it may be possible to identify where in the lifespan of a tree that wooden sample originated. This is because most species of trees follow three growt

QuoteWhat you are suggesting is it depends on which part of a felled tree is used, that the sample is rendered based on where in the rings it's taken from, that the earliest rings (of course are older) will produce an older date, that 'if' it was a 1000 year old tree when it died it will produce a range of c-14 dates that correspond to the trees age depending on which part of the t

Technically it does matter whether the tree is 2 years old or 1000 years old when it "stopped living". In any given year, only the outer ring of a tree is living, i.e. only exchanging with the environmental carbon reservoir it is embedded within. Thus the measured radiocarbon age of a tree depends upon which rings that you sample for radiocarbon measurement. If you sample a tree tha

Most dendrochronology data that I have seen regarding ring counts of Cedar species are typically of individual samples of no more than around 200 years in length, either from living trees or tree samples within site or master chronologies.

This is very true, and people will use (and reuse) whatever material they find useful at the time.

Or, it is quite possible that it was cut down contemporaneously with the construction of the Pyramid. Cedar trees can live for 1000-2000 odd years. So if the Pyramid was constructed circa 2500 BC, and the if tree that the Dixon wood came from was felled around the same time or shortly before, then conceivably it could have began growing around 3500 BC or even before.

One thing that is, on the face of it at least, attractive about the Mirror Universe made of anti-matter on the "other-side" of the Big Bang is the fact that when dealing with quantum mechanics and particle physics, anti-matter can be thought of in terms of "time-reversed normal matter".
