That isn't exactly true. General Relativity predicts exactly how they should behave. However, computing the amplitude for a real event such as an asymmetric supernova is very difficult, and in Weber's day they settled for approximations such as assuming symmetry. Thus they had reason to suspect there was a small chance that their calculations were wrong and Weber's measurements right.

Back in ancient times when tracking cookies were invented there was a furor over them and the US government promised not to use them. That rule is still in effect. That's all.

I'm sure you will find this hard to believe, but we actually do have unemployment benefits here in the USA as well.
Some people who are being paid to work on Free Software (there are probably a lot more of them then you realize) will be laid off, balancing some unemployed who will get involved with Free Software projects to fill their time and keep up their skills. There could be a net loss, but I doubt it. Free Software vendors will continue to do well and more companies will see the value of both using and contributing.

It will lead to the government defining Open Source.

If you allowed a popup to occur you were not being careful.

How many such detectors were there in 1987?
Go right ahead and feed hemp to your wombats.

Yes. Copyright laws. Loaning out a paper book does not involve making a copy.
But it was known that the calculations were approximations.

Lack of money, most likely.
We have Nethack. There is no need for anything else.

This isn't it.

But this thing can't be folded: only bent on what looks to be about a 10cm radius.

US government sites don't use tracking cookies.
It is going to require an 8" telescope to see it at 64,000 km. Brightness is inversely proportional to the square of distance. Extrapolate.
There will be a significant change in direction. How much kinetic energy it gains or loses depends on the details.

Read the article. There is nothing in it about perpetual motion: just an interesting and possibly useful reaction.

No they haven't. Read the article.

These people have discovered an interesting new reaction involving aluminum nanoclusters and water. Read the article.

No you didn't. Read the article.
> The world's supply of aluminum may not be enough to roll this out worldwide.
Aluminium is the most abundant metal in the Earth's crust, and the third most abundant element therein, after oxygen and silicon.
Any increase in costs results in a decrease in profits. This is because any increase in price results in a decrease in sales, even for a monopoly.
You are making no sense at all.

No it isn't. Coyright infringement is a tort, illegal, wrong, and even a crime in some circumstances, but it is not theft.
