    I don't know why every time someone mentions Mossadegh he is moderated insightful. You don't need a time machine, just try to inform yourself better instead of repeating old political propaganda from the Soviet Union.

    First of all, Mossadegh wasn't really that democratic at all. For instance, Wikipedia says "Realizing that the opposition would take the vast majority of the provincial seats, Mosaddegh stopped the voting as soon as 79 deputies just enough to form a parliamentary quorum had been elected."

    Second, Iran was in deep economic trouble from the oil industry nationalization under Mossadegh. With or without CIA intervention, he was doomed to fall sooner or later.

    Finally, if the CIA were able to manipulate foreign governments that well, they should get better results. If they succeeded in overthrowing Mossadegh then why are they unable to overthrow the Islamic government of Iran?

    If there is any problem with relativity wrt black holes, it's that since we can't look past the event horizon, we can't tell if there really exists a mathematical discontinuity in the universe or if something else is happening.

    The problem I see with both special and general relativity is that it's an excellent mathematical method, but it's an ad hoc mathematical tool that cannot be extended beyond certain limits.

    In relativity nothing can travel beyond light speed because that would imply an infinite energy, but that doesn't preclude some other mathematical solutions. However, if one assumes that space and time are quantized, then it seems like the existence of an absolute limit on the propagation speed of waves is necessary, from the Courant-Friedrichs-Lewy condition. This would be a limitation imposed by the structure of the universe itself, not from our calculations.

    In Feynman's "Lectures on Physics" there's a chapter where he explains the concept of "curved" space with an analogy of ants living on a hot plate. Their measuring sticks expand and contract with temperature variations, so their measurements depend on the temperature gradient over the plate. Now suppose an ant engineer invented a new equipment, with a thermometer attached to the ruler which compensates for thermal expansion, they would discover they lived on a flat universe after all.

    Starting with SR and its paradoxes, it seems pretty obvious that a theory that compensated for time and length variations would be welcome. Ten years after Einstein's death we discovered a universal velocity reference in the microwave background dipole, so one of the main tenets of special relativity is not true anymore. Perhaps this universal reference could be used to create a new theory separating the observer's perception of time and length from some absolute timespace which would be much simpler than our distorted measurements lead us to believe.

    I believe the future lies in information theory. Assuming observable events happen in the universe, and assuming that causality exists, i.e. that if some event causes another that relation will exist under all circumstances, then we can think on how information about different events is transported through the universe. Again, this would be a truly absolute limit, not one imposed by our limitations in measuring and calculation.

    Ever heard of Karl Popper? What we currently call the Scientific Method is not even all that old, and mostly formalised by Popper, a philosopher. It's worth knowing his name, because his thinking has had a huge impact on our thinking.

    Wow, what a misunderstanding of the scientific method!

    When I started engineering college, among the courses I took in the first semester where Physics, of course, and Philosophy of Science.

    In the first Physics classes we learned about the birth of science, the professor took us to a planetarium and showed how the planets moved among the stars. Then he explained about how ancient Greek philosophers influenced European thinking, Aristotle being the most prominent in the late Middle Ages and Renaissance periods. Next he told us about Galileo.

    In our first Physics lab class we recreated Galileo's experiment about falling bodies. We timed how long it took for marbles to roll down a through. We measured how long it took to roll down trough different lengths. We assumed a hypothesis of constant acceleration and deducted from it a square law, we tested the time vs. distances we had measured against the hypothesis of constant acceleration.

    All these procedures followed what Galileo did 300 years before Popper was born.

    It's the method, not the words, that make science. Science existed long before Popper put his ideas into words, just like business administration existed before terms like "proactive" and "synergy" were invented.

    This is a common misconception about free software.

    "Many eyes" does not mean every user is a developer, as a matter of fact the vast majority is not.

    The problem is used correctly nuclear power is not a cheap energy source. As nuclear power plants cut corners they find creative ways to ruin the environment

    The problem is that the cost of nuclear power is inflated by the regulations that the anti-nuclear lobby imposed upon everybody as a very effective form of sabotaging the nuclear power industry.

    Different from all other power systems, you cannot find examples of how the nuclear power plants have ruined the environment by "cutting corners". What they are doing is storing nuclear waste "temporarily" but in a highly secure way at the power station plants, instead of moving them to the non-existent "permanent" waste storage facilities.

    The reason why permanent storage facilities do not exist is only because politicians have never agreed on where those facilities should be located and how they would be constructed. each time some proposal comes up it's immediately shot down by the anti-nuclear lobby.

    The anti-nuclear lobby is financed by the taxes we, the citizens, pay. There are NGOs all over the world that get tax-exempt status because they are officially "pro-environment" organizations. Perhaps Wikileaks should tell us how much those NGO directors get in salaries (or do you remotely believe that everybody who works for those organizations is a volunteer?)
