A Presentation: Venus hot break hypothesis

AI Thread Summary
The presentation at the Ancient Venus conference in Houston on July 25 will explore the Venus hot break hypothesis, suggesting that a glancing collision between proto-Mercury and proto-Venus could explain their distinct characteristics. This collision may have canceled the rotational momentum of both bodies, accounting for the slow rotation of Mercury and Venus. Additionally, the transfer of mantle material from proto-Mercury to proto-Venus could clarify the density differences observed between the two planets. The discussion invites contributions from those with the expertise to perform necessary calculations related to this hypothesis. Overall, the hypothesis aims to provide insights into the formation and evolution of Venus and Mercury.

TL;DR Summary
Announcement Venus exchanged rotational energy into heat
Astronomy news on Phys.org
I have thought that a glancing collision between a proto-Mercury and a proto-Venus might explain many characteristics of the two bodies. A glancing collision of two bodies with the same rotation should be expected to cancel some or all of the rotational momentum of both bodies, perhaps explaining the slow rotation of Mercury and Venus. If the collision resulted in transfer of some of the mantle of the proto-Mercury to the proto-Venus this would explain the higher density of Mercury and lower density of Venus. https://nssdc.gsfc.nasa.gov/planetary/factsheet/
Re-accretion of the transferred material to Venus might contribute to its counter rotation.
I do not have the expertise or facilities to do the necessary calculations but perhaps you do.
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
