The interview is a brief account of what is in his book. At the end of the piece we are told the article was first published in the December of 2014 issue of BBC History magazine. |
| 25 Jul 2020 At https://phys.org/news/2020-07-humans-americas-years-earlier-previously.html ... humans in the Americas 15,000 years earlier than mainstream allowed. The findings are published in two Nature articles - see for example https://doi.org/10.1038/s41586-020-2491-6 ... and here we have an interview, short, with Dr Becurra-Valdera of the University of New South Wales in Australia, and Tom Higham of Oxford University. The research papers included various others. |
| 25 Jul 2020 The Homeric Minimum is a postulated solar minimum event dated between 2800 and 2550 years ago, an inordinately long time for the sun to remain quiet. See www.thegrandsolarminimum.com/homeric-minimum/ ... a period of low solar activity is hypthesized in a period of time which Velikovsky was to locate his series of fly bys by an errant planet. |

New archaeological evidence of the first Amricans dated to 33,000 years ago. Two major papers in Nature concern the excavation of 1900 stone tools from sediments in a cave. They were dated in two ways. Firstly by carbon dating (and Bayesian methodology) and by optical stimulated luminescence. Two separate strata were found. |

However, a new study claims galaxy wide magnetic fields are in some way connected to supernova explosions and even to star formation. When evaluating the data beamed back from NGO4217, a galaxy which resembles the Milky Way, they found an X shaped magnetic field structure extending far out of the galaxy disc. In addition, they also found a helix structure and two large bubble structures. |
| 23 Jul 2020 Anthropology is a funny field of science. Lots of waffle. At https://popular-archaeology.com/article/the-shamans-world/ ... shamanism dates back to an early stage of humanity, we are told (quoting Eliade, 1964). Is this clever stuff or are they getting their bootlaces in a mix. It sounds like clever stuff and it is certainly erudite. However, it occurred to me that it highlights the different way in which a catastrophist, including a Velikovskian, might interpret mythology as opposed to the great and the good. |
| 22 Jul 2020 At https://phys.org/news/2020-07-idea-earth-outer-shell-broke.html ... In this article we are told that it is well understood that volcanoes and earthquakes can be explained by the 50 year old theory of Plate Tectonics. This theory claims earth's outer shell, or lithosphere, is subdivided into plates that move relative to each other, concentrating most tectonic activity along the plate margins. Surprisingly, we are then told, the scientific community have no firm concept on how plate tectonics began. |
| 22 Jul 2020 I thought it was already recognised that volcanoes on Venus were a source of its anomalous heat. That heat was used by Velikovsky to suggest Venus was a young planet - and had not yet cooled down. The idea Venus suffers from runaway global warming as a result of Venusian greenhouse gases, such as co2, has been accepted for a number of years. It seems even the presence of volcanoes on Venus did not cause a second thought. Apparently, mainstream insisted they were inactive. That sounds like not facing up to the facts, an all too common attribute nowadays. |
| 20 Jul 2020 Clarification on the recent piece from the Daily Mail. The actual study does not mention climate change at all and has been inserted by the Daily Mail journalist, or an editor. It may of course have been inserted by whoever released the press story to the media. The full paper can be read at www.mdpi.com/2076-3263/10/7/270/htm ... The event has nothing to do with climate change and is purely a geological phenomenon. |

Interactive orbit visualization. 3d visualization showing the orbit of Comet C/2021 A4 (NEOWISE) with respect to the major Solar System objects. 15 days ephemerides. Table showing celestial coordinates and magnitude of Comet C/2021 A4 (NEOWISE) for the past and next 7 days. Named Comet C/2020 F3 NEOWISE, the comet made its once-in-our-lifetimes close approach to the Sun on July 3, 2020, and will cross outside Earth's orbit on its way back to the outer parts of the solar system by mid-August. The comet cruised just inside Mercury's orbit on July 3. hide orbit diagram For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances. The spacecraft will sit in a parking orbit around the Lagrange point L2, 1.5 million kilometres away from Earth, until an interesting ‘pristine’ comet visits the inner Solar System. It will then intersect the comet's orbit to study its nucleus, gases, dust, and plasma environment. More about Comet Interceptor. In July 2020, comet NEOWISE (short for C/2020 F3 NEOWISE) has thrilled skywatchers in North America, in Europe, and in space. If you don’t spot the comet this time around, you won’t get another chance. It has a long, elliptical orbit, so it will be approximately 6,800 years before NEOWISE returns to the inner parts of the solar system.
Additional Information
An orrery is a model of the solar system that shows the positions of the planets along their orbits around the Sun.
The chart above shows the Sun at the centre (the yellow ball), surrounded by the solar system's innermost planets.
Click and drag the chart to rotate the camera angle, or use your mouse wheel to zoom in and out. Alternatively, you can use the slider below the chart to adjust the zoom level. As you zoom out, the solar system's outer planets – Jupiter, Saturn, Uranus and Neptune – will come into view.
The date slider lets you move forwards or backwards by a few months to see the motion of the planets along their orbits over time.
The top panel shows where the planets appear in the night sky, as seen from the Earth. The yellow line marks the zodiac – the annual path of the Sun across the sky – and the grey lines show constellation boundaries.
The color coding of the orrery indicates the time of day when each planet is visible. This depends on the direction in which the planet lies, as seen from the Earth. If our line of sight to a planet is widely separated from our sight-line to the Sun, the planet will be easily visible for much of the night. If not, the planet will appear very close to the Sun.
Comet Neowise Orbital Period
Areas of the chart above which are shaded green are easily visible from the Earth; areas which are red are hidden by the Sun's glare. Areas which are dark blue are visible in the morning sky, while areas which are light blue are visible in the evening sky. This color coding can be turned off by deselecting the option 'Overlay planet visibility'.
Neowise Comet Orbit Path
By selecting the option 'Mark perihelion / aphelion', labels can be added which mark the closest and further points from the Sun along the orbits of each of the planets. The Earth's orbit is additionally labelled with the points it passes on the first day of each month as it makes its annual circuit around the Sun.
