    I don't feel that I have the talent to write a science-fiction novel that anyone would want to read.

    But if I were to do so... and I were to indulge my own feelings about how
    FTL would play out in real life, instead of following genre conventions...
    I might end up with a story in this setting:

    Humanity lives underground beneath the surface of Proxima Centauri b. Both
    Sol and Alpha Centauri have long since gone nova, but Proxima Centauri
    still has most of its future ahead of it.

    People live in gigantic dome-shaped caverns, brightly lit by sunlight sent down narrow shafts from the surface; simple optics allows this, and it's
    still more efficient than any form of artificial lighting.

    Before Alpha Centauri went nova, because its system was near at hand,
    unlike Earth, they once obtained resources from that system, to add to
    what was initially brought from Earth.

    Life goes on. People grow food, they tend to forests, they have and raise children. But this former colony of long-dead Earth has a purpose. As on Earth, people pursue the arts and sciences; crafting sculptures and
    paintings, writing symphonies; researching the nature of matter and the
    truths of mathematics. But one particular ambition has pride of place as
    the purpose for which Man extended his domain to that world.

    And that pursuit, of course, is the quest for FTL.

    Maybe in another few million years our scientific knowledge will advance
    far enough so that we can start working on it directly...

    This scenario, of course, assumes the Alcubierre version of warp drive
    didn't pan out (perhaps because time travel into the past is impossible,
    so something non-relativistic, based on quantum mechanics instead of
    general relativity is needed)...

    Although their underground domes have beaches, and small hills to climb,
    and new caverns are regularly dug, and life can expand into them...

    while advanced technology provides material comfort, living in a
    constrained society with only a very slow rate of growth possible,
    oriented around a goal which may be impossible, and which is certainly at least incredibly distant of achievement...

    the story would be about finding purpose and maintaining hope (or failing
    to do so) in the face of a fundamental existential ennui that undermines
    all the distractions that are used in an attempt to keep it at bay.

    the story would be about finding purpose and maintaining hope (or
    failing to do so) in the face of a fundamental existential ennui that undermines all the distractions that are used in an attempt to keep it
    at bay.

    Although I envisage them using CRISPR to increase the human life span, and give us giant brains (by keeping rapid brain growth continuing till age 4, instead of ending at age 2, so childbirth is no harder)... I don't think
    they will be able to change human nature as established by millions of
    years of evolution.

    Hence, I see humanity facing existential ennui since it is no longer
    possible to carve out empires through making carbonated drinks with new flavors, or through selling fossil fuels, or through making war on one another.

    However, I have now worked out how to introduce an element of conflict
    into the story. I'll have to move to an earlier time - Earth and Alpha Centauri are still around, it's only at most a few thousand years since
    the landing - enough time to get comfortably establlished, but still very early on in their quest.

    A faction - the Plan B faction - emerges with an idea that will change the very foundation of the society being built.

    Given that the population of Proxima Centauri b will be in the millions,
    and not in the billions of Earth's heyday, can anyone be sure that even trillions rather than billions of years will be enough time to invent FTL without the magic of exponential growth working for you?

    So they propose devoting some resources to an intermediate goal: inventing uploading, to make slower-than-light travel more practical for
    interstellar expansion.

    One argument advanced against the plan is that absent FTL communications,
    at the least, having a slowly exponentially increasing human population on
    a vast number of worlds... won't produce as much benefit as would normally result. Instead of synergy between more minds working together, all there would be is a bigger chance of someone getting a lucky break.

    But communications are at the speed of light, which is much faster than
    the slower-than-light travel speeds that can be attained, enough so that communications delays between nearby worlds are only a few years, so some synergy is still there, it will be replied.

    Plan B are the good guys who win the day... ta da, a story to tell.

    Indeed But their may be no GUT no TOE but at this stage of the Universe so far from the origins and with the constraints of Light Speed and human fragility it may be impossible by what amount to distances in time and

    Yeah, I'm with you on that.

    There are these quantum systems spread out over space where
    information has to move without the usual speed limits, just
    to make sense of the measurement results. But this flow inside
    can't be controlled from outside - you can't really send useful
    info through it, and no energy gets passed along either.

    What's tough to swallow is that from another frame of reference,
    this kind of instant info transfer looks like it's actually
    sending information back in time. Maybe we just have to come
    around to that idea. It can't cause time paradoxes since we
    can't encode any useful information into it.

    But maybe the future determined the past.
    Lots of SpecFic written about people who go back in
    time to start Life on the Primeval Earth simply by
    going there and dying or even merely excreting.

    I think there is even a Doctor Who about
    the Doctor, Tardis and companion visiting both

    who is to say that these only represent the

    Right now we are ~13+ Billion years from
    the beginning and trying to figure out how those
    few moments determined the present state of
    things. If the present on the other hand sent
    information back to the beginning it might have
    set up the conditions that resulted in present
    conditions.
    Not that this is of any importance to us
    at the present moment. We can in no way
    change our present to have magic working
    because we have a simply logical universe
    already and it is better so. IMO of course.

    Minor nit. Neither Sol nor Alpha is going to go nova. But both will eventually shed much of their mass as red giants, and become white
    dwarfs, giving much the same scenario.

    And you are right about Proxima. All this will occur before Proxima is
    more than one percent of the way through it's main sequence period. And
    you definitely want to live underground as Proxima is a flare star.

    Still, any of our descendants living in this period, five billion years
    from now, will be about as closely related to us as we are to cyanobacteria.

    If you want to, you can dispense with Alpha. Proxima is weakly bound to
    the Alpha-B pair, with a period of 550k years. Perturbation of the
    orbit by a passing star or giant molecular cloud should have a decent
    chance of kicking it out of that orbit over five billion years. Whether
    that chance is 1% or 99% I lack the skills to estimate.


    On the other hand the picture of Proxima orbiting the white dwarf
    remains of alpha and B is a powerful one.


    Anyway, write your story. Years ago I found that trying to write
    fiction gave me a better appreciation of the fiction I was reading, just
    as playing an instrument, however badly, increased my enjoyment of music.

    When a theory has been wildly successful in a variety of areas, it is
    absurd to drop it in the face of a contrary observation when another explanation has not been ruled out. The theory is put in some doubt, to
    be sure, but not abandoned. Not immediately, anyway.

    For example, deviations in the orbit of Uranus put Newton's theory into
    doubt, but people speculated that the presence of an unknown planet
    could be responsible. Neptune was discovered, and the theory survived
    that test.

    On the other hand deviations in the orbit of Mercury could not be solved
    in this way. A perturbation mass, Vulcan, was hypothesized, but it did
    not do us the favour of existing. The theory had to be changed, though
    it took a while (Einstein figured it out in 1909 but didn't publish for several years).

    Conservation of mass and of momentum both appeared to be violated in
    neutron decay circa 1930. But both of these laws seemed to apply
    everywhere else, so it was proposed that a near-invisible particle was a product of the decay, carrying with it the required energy and momentum.
    And the particle was discovered a generation ago.

    Since then many particles have been predicted on purely theoretical
    grounds, and not found for decades. If we live long enough we may hear
    of the discovery of a wino or a slepton - or we may hear that
    supersymmetry has been ruled out, to much gnashing of teeth.

    As to dark matter, the observational evidence is strong. And for that
    matter, what a priori reason do we have for thinking that all matter
    will interact strongly with the electromagnetic field?

    While our theories cannot possibly be the exact truth, the deviations
    from GR in galactic rotation rates, etc, are far more plausibly
    attributable to dark matter than to flaws in the theory. Still there
    will always be a strong element of doubt until we have both more direct evidence and a good theoretical explanation.

    So yes, it makes sense to hang on to current theory, at least for
    a while.

    The trouble is, of course, with such a "conflict" as its hook, the story
    is likely to be comparable to, say, Mack Reynolds' L-5. Which I think was widely regarded as a snooze-fest.

    For example, deviations in the orbit of Uranus put Newton's theory into >doubt, but people speculated that the presence of an unknown planet

    that test.

    On the other hand deviations in the orbit of Mercury could not be solved

    I never said it didn't make sense.
    I just pointed out that it has turned, on occasion, to involve a lot
    of wasted time and effort.
    But they may eventually pull something out of the hat: after all,
    Copernicus' rewrite of Ptolemy (still with circular orbits and
    epicycles, just a return to the early heliocentrists) led eventually
    to Kepler and the realization that a force from the Sun could keep the
    planets (the Moon, of course, orbited Earth) in elliptical orbits
    (with a certain property).
    And a circle is a degenerate ellipse, so Aristotle wasn't entirely
    wrong. Any more than Newton was.

    What's tough to swallow is that from another frame of reference,

    information into it.

    With an Alcubierre drive, which is based on General Relativity, and hence
    must strictly follow all the rules of relativity, causality is an issue.

    With FTL travel or communications based on quantum entanglement, however,
    it's entirely possible for a preferred quantum reference frame to exist,
    from which all possible FTL goes forwards in time.
