Not so good news for science
I agree that this is good news. However, I am surprised. I don't know BSL and I know that it is quite different from ASL, which I am studying right now. I am surprised that BSL would require long spelling without special signs for these terms. For example, in ASL, I'd simply sign "green"+"house"+"effect", which are three very short and common signs. Here is the explanation of this effect in ASL, using only standard signs:

Why "even light"?
Which point? What consequence of gravity? What is the difference between this demonstration and a demonstration of a weight hanging on a spring? A heavier weight stretches the spring more. What does the blanket demonstration demonstrate that the simple spring does not? You put heavier and heavier weights on the spring, and at some point, the spring snaps. Does this demonstrate a black hole? How?

Why "even light"?
Consider a collapsing star of mass M, not a black hole. As it collapses, its size changes, but the mass stays the same. When its radius becomes smaller than 2GM/c2, it becomes a black hole. With the same mass. Did a correct point get across?

Why "even light"?
I think that this demonstration is wrong for a number of reasons: 1. Blanket breaks. Spacetime does not. 2. The depression in the blanket is caused by weight of the object. A black hole is caused by its size. 3. The depression is caused not by the object's gravity, but by the Earth's gravity. 4. The blanket responds to the weight due to its elasticity. The spacetime does not. ...

Any sum? Could you give an example?

Why "even light"?
The blanket exercise demonstrates a breaking point. What does it have to do with black holes though? I mean, you got the Earth, the weight, and the blanket. What does the blanket signify? What does a depression in the blanket signify? Regarding the Hotel California, I don't see any similarity with the black holes at all. You could just use a mousetrap instead.

I watched it and liked it. A lot. I clearly remember that I liked it. Don't remember much more than that, but some vague images. Well, it happened before you were born ...- Trouble with Chrome and creating new topics?

Thank you for the explanation. Yes, statism vs collectivism. Soviets stayed in existence and in the name of the country, powerless.- Observations on Socialism
Perhaps, although I am not familiar with these terms exactly.- Observations on Socialism
The original vision for the "society at large" was not a government but a hierarchical structure of "collectives" (called, Soviets).- Observations on Socialism
Yes, it can be collective OR governmental. Not necessarily governmental. That used to be slogan for communism. The slogan for the socialism was, 'From each according to his ability, to each according to his contribution'.- What is the nature of our existence?

Causality does not work backward in time as per SR. SM obeys SR. I think you're right. I don't see it as a model. It is used in making models.- What is the nature of our existence?
On elementary particles level, when two particles interact, they both change. So, this event affects the future events of each. Isn't it the intersecting of the chains of causality?- Muon precession differs from SM prediction
