    You mean the A/C? Oh yeah, I hadn't thought of that. And if someone can come up with personal A/C units - bit like one of them thar VR thingies - nobody'll need to wear space suits? Sorted - count me in! :mrgreen:

    Watvh the movie "The Martian" for one idea. The author stayed in close contact with NASA and others yo stay within today's technology with few exceptions - such as the storm on mars and an ion drive larger than we can build and power today.

    It's still sci fi, but not crazy.

    Scientific speculation isn't a theory.

    A theory requires an exact mathematical model that has been peer reviewed and tested ad infinitum. It must also solve a problem or provide new insights into the nature of the physical world.

    What scientists call a theory, most people would call a proven fact. The standards for evidence, for a hypothesis to become a theory, are far greater than for things the average person accepts without question.

    Imagine going to a mechanic and require that thousands of other mechanics duplicate your problem and solution, mathematically prove how it failed, and publish those results for review, before you would pay your bill! That's science!

    Put another way, if the standards for legal evidence were as high as the standards for scientific evidence, no one could ever be convicted!

    We put people to death on far less evidence than is required for a scientific theory.

    Couldn't have put it better myself. It works like this: get a job where you keep looking for something that doesn't exist, such as 'black holes' 'gravitational waves' 'exo-universes' blah blah, and you've got it for life. I don't blame them though - I even wish that I could get a piece of the action, but I'm not 'in the know'!

    I agree...I don't have much interest in 'trying' to colonize Mars...my preference continues to be a fully sustainable biosphere spaceship on a one-way voyage 'out there'. Without new physics to magically transport humans at much higher speeds, or near SOL speeds, even this venture is more about novelty than practicality...

    Pretty much...although things can change...by the time they do...it will be far down the road from today...perhaps too far...

    I would not say that the Theory of Evolution is "an exact mathematical model? I would say it's more of an explanation, while based on 'facts that we know'...so is it speculation or theory or law?

    Evolution is more of a Religion due to the many gaps and other Data that is filled in by X - Y, A + B = C, there is simply too much guess work involved, one day facts will become known, and I am sure it will include bits & bobs and other elements from everyones books.

    Science has moved way past Darwin and his Theory of Evolution by Natural Selection, which is nowadays included in a set of theories from a wide field of scientific study, called the Modern evolutionary synthesis, which collectively explain how evolution occurs.
    It's supported by observations throughout the fields of genetics, anatomy, ecology, animal behavior, paleontology, and others.

    Nah, he's just having a bit of fun with the disciples; it's his way of finding out just how much barmy stuff they'll believe before they start using their brains, er, I mean before they start to question and challenge. I mean who'd grudge him that?
