If the insurance business is on such a knife edge , I wonder if it's a good idea that people rely on corporate entities to provide it, when they could go bust if faced with extraordinary circumstances. Better to have the governments doing it I'd say.

The insurance claims are backed by the float, and then the insurance company has its shareholders capital at stake, and then the insurance companies are generally insured by a reinsurance company, so there are multiple layers of capital backing policies, as long as policies are sold at the correct price, and courts don't force insurance companies into paying settlements on things that weren't covered in the contract, things should be fine.

----------------------------------

Here is warren talking about how low interest rates are forcing the cost of insurance premiums up, because most companies can not earn as much on their float any more, especially in Europe where there are negative interest rates.

 
Anyone see the TV program Sex War Robots (SBS)?

I've never seen anything so depressing and frightening! The whole world is suddenly going to become unrecognizable due to the AI explosion. That is unless we/it self destructs in a robot war.

Whilst nothing appears to be changing at 'street level', when the street level change does appear, things are likely to get hectic in a big way.
 
After 20 years in space and the last 7 spent orbiting Saturn and its moons, Cassini completed its amazing mission just 30 minutes ago when, as planned, it crashed into Saturn. Congratulations NASA.
 
Sad to hear the mission has ended. What a great little scientist it was. (Sorry for the anthropomorphism).
 
That was a fascinating theory of how the Pyramids were built. Floating the building blocks up a water lift on the side of the pyramids ! I reckon it would be worth just developing such a techology today to see how it would work.
The comments on the You Tube site raise many questions.

It seems that nothing truly lasts forever, not even universal speed limits:

Interesting....

However, when I came to this part; This produces an almost identical light pulse that exits the chamber and travels about 60 feet before the main part of the laser pulse finishes entering the chamber; my reaction was the same as that stated by one scientist towards the end: Aephraim Steinberg, a physicist at the University of Toronto, said the light particles coming out of the cesium chamber may not have been the same ones that entered, so he questions whether the speed of light was broken.

Still, if these experiments eventually prove that the speed of light is not constant and an absolute limit, it might open up some new breakthroughs in physics, just as Einstein's and others did when they hypothesised and then was subsequently proved that time itself is not constant throughout the universe.
 
Anyone familiar with the way electrons flow when an electric potential is applied to a conductor, will likely have gravitated to a similar opinion to Steinberg's. (I happen to share that particular view)

However, this discovery does, at the very least, present a credible challenge to popular conceptions concerning the speed of light and its dependence upon the presence of a conducive medium.

Given the outcome of that experiment, do we truly know the maximum potential speed of a single photon?

Do we truly know that aether doesn't exist?

Edit: Apart from his plagiarisation of Newton's formula for kinetic energy, Einstein's theories were utter rubbish and proved how easy it is to bamboozle otherwise intelligent people, including himself!
 
Holy ****. Give it 5-10 years and equip it with next gen arsenal of weapons and it will make Robocop look like a kid's toy. For real.

 
An opportunty to understand Carbon 12, 13 and 14 (che ??) and how the changing proportions of these isotopes in the atmosphere are part of the evidence that CC is due to human emissions of greenhouse gases.

Carbon Isotopes Part1 The basics.

For the average citizen, who perhaps has a rudimentary grasp of general science, one problem with the topic of climate science is that it is such a huge subject which draws on a wealth of knowledge from many different science disciplines. It is easy to get lost in the weeds of this detailed knowledge which informs our conclusion that the current changing climate is due to human emissions of greenhouse gases. The broad strokes of climate science may be grasped with a limited amount of scientific knowledge: carbon dioxide and other greenhouse gases absorb and release heat (infrared radiation)...burning fossil fuels releases CO2 into the atmosphere and this increasing amount can be measured...more CO2 in the atmosphere will mean more heat energy in the climate system causing climate to change. But that basic knowledge is grounded on many more complicated lines of evidence: the weeds, which can often be very confusing to the science novice.

I posted this video in the Elon thread, But I thought it should be here to.

Succesful test of the falcon Heavy rocket with 3 of the first stage rockets returning to earth and landing successfully to be used again.

Between the 25.00 and 27.30 minute mark you see the landing of the first stage rockets returning to earth and landing perfectly.

 

An incredible feat for a private company.

That dual booster landing was incredible.
