Two years later, and over 5 Million deaths, and some are still questioning the measures to contain Coronavirus. And I read comic books and science fiction as a youngster; not fantasy.

Creation and Destruction of Imaginary Particles in A vacuum and Relation to Size of Universe
In the case of inflation, it is the 'roll' from the false zero energy of the vacuum to the real ( ? ) zero level due to a symmetry break, where vacuum energy is traded for exponential inflation. If that is also the case for expansion, then vacuum energy would be similarly decreasing. And if we consider the Mexican hat potential, then even periods of accelerated expansion could be exlained in terms of oscillations about the real zero level.

War Games: Russia Takes Ukraine, China Takes Taiwan. US Response?
And the UK has supplied anti-tank weapons and advisors ( trainers ) to Ukraine. Russia has always claimed to be the protector of the Slavic peoples. And V Putin has said' Our Russian brothers in the Crimea and Ukraine are being oppressed, we have to save them." Reminds me of a German leader, 83-4 years ago, who said "Our Germanic speaking brothers in the Sudetenland, the Danzig strip, and Poland, are being oppressed;we must save them." At least D Trump offered to buy Greenland, not invade.

Under-Water Volcano seen from Space:
Apparently the 'middle' of the old island has collapsed into the caldera, and it is that collapse that caused the tsunamis. I wonder if the island is on any ailiner flight paths ( Iceland 1991 ), if the abrasive dust will pose dangers to aviation, or if the majority of vulcanic ash was filtered by the water. Kind of humbling, when you realize the power of nature.

Was there a real Jesus of Nazareth ?
the word 'truth', and its many subjective meanings,is a touchy subject around here.

The Novak Djokovic Debacle:
I have always maintained that 'freedoms' and 'rights' are granted by the society you live with; no one is born with them. If society deems it necessary that everyone be vaccinated against public health threats, then make it mandatory. Don't waffle and include conditions which can be circumvented.

Was there a real Jesus of Nazareth ?
For one thing, the thread title concerns the existence of Jesus of Nazareth. But the last few pages seem concerned with the existence of a historical Saul of Tarsus, and whether his writings as St. Paul were 'truthful' or not.

Cosmological redshift, thought experiment
An understandable ( I hope ) explanation of gravitational binding vs. expansion ... If we consider gravitational potential as a negative potential, the Cosmological Constant/vacuum energy is then a positive scalar constant throughout the universe. ( the CC was used by A Einstein to balance the global gravitational potential ) The gravitational potential can be imagined as potential wells, or pits, and the CC/vacuum energy is, then, like a small step-ladder. If the well/pit is more than 1 m deep ( 2 m, 10 m, or even 1000 m ), but your step-ladder is 1 m, you can't get out, and are gravitationally bound. If the gravitational potential is much less, as it is in the vast expanses between galaxies and galaxy clusters, such that the well/pit is only 1/2 m, less than 1 m or none at all, then the step-ladder would get you to a height where you can 'fall away' from the pit, and you are not gravitationally bound. IOW, there is a 'threshold' that the CC/vacuum energy has to exceed before expansion can take effect.

Cosmological redshift, thought experiment
If the box is a bound system, that means the Cosmological Constant/vacuum energy forcing the expansion, does not rise above the lthreshold evel of gravitational binding which resists the expansion. That would mean separations inside the box do not increase with time, and there is no recessional red-shift.

The Novak Djokovic Debacle:
I'm not aware of all the details, but I thought the judge granted the stay because the Australian government, and Tennis Australia, applied their Visa rules inequitably. Famous people, whether tennis players, movie stars or politicians, don't get to play by different rules when it come to infectuous diseases; fame does not protect you, or keep you from infecting others.

Was there a real Jesus of Nazareth ?
very well, let's re-hash a topic that was done to death .... Jesus was a political protester, and there was a lot to protest about in Judea during the Roman occupation, who was put to death. Jesus was obviously not his real name, because there are historical records of those times and he is never mentioned, although there are mentionings of political protesters put to death by crucifiction. Subsequently, his message ( of political reform ) was subtly changed and re-purposed as a 'religious' message. This did not happen suddenly, but over the course of several hundred years, and by several people. And I'm not necessarily claiming that the people who changed his message over these hundreds of years had an unscrupulous purpose, but by the 7th-8th century, thehead of the Christian religion was the most powerful man on Earth, such that even the Emperor ( of the Holy Roman Empire ) bowed to him. Until there is proof to the contrary, that is my opinion.

Was there a real Jesus of Nazareth ?
That previous thread might be 8 years old, but, if no one found any evidence that Jesus of Nazareth was a real person in the last 2000 odd years, I don't think they would have found any additional evidence in the last 8 🙂 .

War Games: Russia Takes Ukraine, China Takes Taiwan. US Response?
Unfortunately, Germany is rushing to decommission its last remaining nuclear reactors,because they are not 'green', and, because of the resulting energy shortfall, moving to classify natural gas ( from the pipelines ) as 'green' ( ? ), to make up the energy shortfall. IOW, import more Russian gas.

Was there a real Jesus of Nazareth ?
There was a previous, rather lengthy, thread on this very topic several years ago. I suggest a search, and a good read.
