    I'd think that a smart physicist would do anything he could to avoid FTL claims, because FTL claims also violate 2nd Thermo, and 2nd Thermo is a mathematical law -- it applies even to such things as data compression. To put it shortly, if you can do FTL particles, then you can send information back in time. If you can send information back in time, you an set up contradictions (overdefinition of equations, 3 equations 2 unknowns kind of thing). The contradictions themselves, by quantum mechanics, cancel themselves out.

    Moreover, sending information back in time itself violates the 2nd law of thermo.

    If you're going to violate FTL, you have to set up a system where contradictions are conceptually impossible. Whether or not that is ever going to be concievably possible, I doubt. But if you're just going to throw a particle FTL... I'd say no.

    A1*B(N) + A2*B(N-1) + A3*B(N-2)... + A(N-1)B2 + A(N)B1.

    No modding. I'll just wait until the modding is mostly done, and then reply. Usually, when people make a joke, they include some truth (or truth as they see it). Same is true for trolling. So I'll answer you as if you were serious.

    Let me start by saying that the preponderance of evidence seems to imply the Bible is true. Considering that a miracle is best defined as a documented historical event that defies our understanding of our world, go and google "Catholic miracle", "Methodist miracle", even "Mormon miracle". Then pop over to a few other religions: Islam, Buddhism, Judaism. You'll find that Judaism has very limited miracles after 70 AD. Aside from the star in the moon, Islam has only those of the classification of "potato chips that look like a praying muslim." Buddhism doesn't seem to have much, and so on. But where they do have miracles, is when they involve Christians. Christianity has them regularly, and they are convincing.

    But to answer your question, let me go you one better. Consider the lament after the two exiles, "they took the young men to grind, and the children were crushed under the wheel." Basically, you conscript 10 men to pull a large stone roller around in a circle, grinding grain. But if a couple of them are children and wear out, and you're beating them to go so fast that the children get crushed into the grain... well... it begs the question how a loving God can use such attrocities as a means of grace?

    Thing is, He doesn't. He warns them ahead of time that if they go running after other gods, it's going to come to this. Moreover, the Bible identifies the other gods as thieves and demons, and pronounces a judgement of death upon them. So those other gods basically are like kidnappers who lure children away from the schoolyard with treats, only to kidnap and murder them when it's too late for them to return.

    So the Creator God wants to preserve His creations, and the false gods are out to kill and destroy. It isn't the creator God's will at all. But if he publicizes the case, the bad events can at least be a warning to others.

    But what do you do, then, with those humans who actively participate in luring children out to the kidnappers? Normally, that's a capital offense. Now, the Bible does also identify men who lie with other men (among others) as those who are given to that because they worship the creation, not the creator. So that may apply to your answer.

    But as a Christian, I tend to prefer Jesus' answer to the adulteress: "go, and sin no more" (repent, and stop sinning. Then we don't need to condemn you. We can forgive you.)

    So how do you repent? Peter noted the difference between himself and Judas: that worldly repentance leads to death, but Christian repentance leads to righteousness not to be repented of. But you can't have Christian repentance, unless you have a clear vision of God. Peter saw how he had hurt Jesus in denying him (Jesus looked at Peter, and Peter was grieved and ran away in tears). So you have to ASK Christ to give you a clear vision of God for repentance, and then seek Him with your whole heart until He does.

    But it should be easy to start to see Him. Pull out the Gospels of Christ, and read them as a hero story. It's more poignant than the made-up story of the movie "Titanic." God likes hero stories too. Then look through history, and try to find what true hero stories you can, that even come close to matching them.

    First of all, you'll see that there are very few, percentage-wise. But among those you do find, you typically are going to find that (a) they were not such a hero until they were empowered by Christ's own death and resurrection, and (b) that they did it by emulating Christ, and underlying His own hero story. It's only in such a context that you can find the Mother Teresas, the Maximillan Kolbes, and the John de Brebeufs of the world, as well as the Bernadette of Lourdes', the St. Patricks, and the stories of Peter, Paul, the Atlas Seven ("Of Gods and Men"), and others.

    And no, these are not fictional. Part of their perfection is that they really happened.

    When you have a basic understanding of how philosophy and theology need to interact in order to be rational, and how they in turn need to interact with daily life in order to be at all relevant, you can quickly recognize drivel. In religious language, "drivel" is "heresy" (an active "taking away" of some vital part of the equation, like the 2nd law of thermo.)

    So when he talks about heresy, he's saying that the professor can't get some logically vital part of the religion through his skull, usually because of some other agenda he has.

    Aside from that, morals and ethics *were* created by religion, purely as a leftover castaway. They are spinoff industries. Morals and ethics are what you have left of right living, when you try to take away all the basis (God's own righteousness) from which it originated. Morals simply means "reasons of action", and Ethics simply means "a consistant rule of behavior." As such "More for Me" is an Ethic, though self-destructive. But it isn't right living, and can never be, because its source is removed.

    Tenure, like "academic freedom", was instituted for the protection of university management. More specifically, the university management would get various donations-on-a-string from various political, business, or civic leaders, which would be deadly to accept, and impossible to turn down.

    Too many of those, and a dean's going to be fired no matter what. If nothing else, the conflict between the Lefthanded String theory which is demanded by the last donation, and Righthanded String theory which is demanded by the next donation... would cause conflicts.

Quite simply, the Deccan Traps are evidence of India being partially torn in two.

Therefore, it takes momentum transfer, not energy transfer, to affect plate motion.
