Replace BTC with USD in your entire statement, and you'll have your answer as to why everyone (including governments) sees the USD as some sort of "magically universally accepted currency".
Totally. wrong. The magic words that exist on USD and don't exist on BTC are "legal tender". It means the bad boys with guns of the US government protect the purpose of your USD's on US soil, as a means of exchanging goods and services. In other words, currencies become accepted because regional powers are willing to kill, maim, and imprison if need be to make it so.
An additional point to this is: because the US Dollar is a currency agreed upon by the people of the US, through our government, as a medium of exchange for goods and services, it is in fact backed by the current and future productivity of the United States, which it turns out is still pretty damn valuable.
First define a known force. Right now the unit of force is defined in terms of a kilogram.
That's easy! Gravity, of course!
Unfortunately for the theory of supersymmetry, this is yet another blow.
Ok, but why? Anyone care to explain this for me?
In simple terms (that I hope are accurate), supersymmetry is one of the predictions made by string theory (although the concept of supersymmetry pre-dates string theory). I believe there are other theories that incorporate supersymmetry as well. So, if the predictions made by supersymmetry don't hold up, any theory that is based on it will need to be revised or abandoned.
What kind of bullshit logic is that? Something is broken, everyone hates it, so let's put all our efforts in making the alternatives better? How about contributing to PHP and fixing what you're bitching about instead of, well, bitching about it? You know, it's open-source and all.
Speaking of bullshit logic, why should I contribute to a language that I hate, instead of doing something useful in a language that I actually like?
A fair point, which deserves an answer. The reason they're not thinking that is, probably, that there has as yet been no evidence that there were humans in mainland Greece anything like that early. The earliest known sign of human habitation in Europe is only ca. 40k years old.
Humans in Africa, however
There is no evidence for Homo sapiens in Europe 130k years ago. However, according to the article, these tools are Acheulean technology, which was used by Homo erectus. These were not modern humans, and this technology was pretty widespread across Europe, as well as Africa and Asia.
