    The Big Bang Theory a Fairy Tale? So says presidential candidate Ben Carson....

    A childhood friend of my wife married a biologist, who does not believe in evolution, who teaches biology at NC State...maybe he's retired by now.

    Where does photon energy go in universe expansion?

    [Moderator's note: Spun off from another thread, where it was off topic. Please start a new thread when you have questions on a new topic.] Photons lose energy when they travel long distances. Where does that energy go? What happens to that energy? Is there any theory regarding this?

    B How close are we to producing a self-replicating machine

    Here's one idea: http://io9.com/how-self-replicating- spacecraft -could-take-over-the-gal-1463732482 and it's an old idea.

    B How close are we to producing a self-replicating machine

    Every candidate, however, requires some sort of energy input. A riprap 3d printer requires electricity. Artificial bacteria eat things. Surely you are not visualizing a self-replicating machine as some sort of perpetual motion system?

    B How close are we to producing a self-replicating machine

    I presumed that the self-replicating bots would be used to colonize other planets in other star systems, which apparently, in this case, was an incorrect assumption. That is the most common reason why I have heard people propose the creation of self-replicating bots.

    B How close are we to producing a self-replicating machine

    Humans obtain chemical energy from what they eat. ATP to ADP, etectera. Ultimately, all the energy that powers biological organisms comes from sunlight. Sunlight has very little energy between stars.

    B How close are we to producing a self-replicating machine

    How could a self-replicating machine power itself without violating Conservation of Energy? From starlight near suns? Would it then just be drifting between stars?

    Air Pressure half as mile underground

    Years ago, I went to an Iron mine in Minnesota, and we took an elevator half a mile underground. Why wasn’t the air pressure down there stiffling?

    No such thing as instantaneous speed?

    dx/dt is the velocity. A falling object instantly attains an acceleration, dx^2/dt^2, insofar as I know. but if that acceleration were to change, its rate of change, dx^3/dt^3 is the jerk. If post 2 answered that question, it went right over me. I guess the next one up the line is jounce...

    No such thing as instantaneous speed?

    Can you have instantaneous speed? What about jerk and hyperjerk?

    What Are Imaginary Volumes in Complex Numbers and Algebras?

    Imaginary numbers enable one to envision a lot of ideas. But what kind of numbers/algebras would enable us to work with imaginary volumes? Volumes, by definition, always seem to be positive, since any cubes are. What kind of numbers would give/allow a more complex picture?

    Dr Who Fans Unite - Join the Community

    I loved Tom Baker as Dr Who, because he had a wild sense of humor. His interpretation of Dr Who was comical.

    Redshift & Far Distant Stars: Effects on Temperature

    Wouldn't the Redshift result in decreased heat from far distant stars, resulting in an equilibirum temperature, much lower than the average star?

    Perpetual Motion: Particle Spin & Earth's Role

    Elementary particles spin. So does the Earth. Spin does work. The spin of electrons and other elementary partlces never stops, or slows down. Why isn't the spin of particles considered to be perpetual motion? Doesn't particle spin violate the laws of Thermodynamics?

    Why do all elementary particles spin?

    Thanks for the references. Not sure I fully understand, but the general drift of your argument is comprehensible enough to give me something to reference.
