    So far so good. Curious that there is a horizontal diffraction spike
    that stands out above the noise in addition to the hexagonal symmetry
    main spikes that you would expect from the geometry.

    No trace of them in the other 4 segments at top and bottom.

    Being a Christian, I actually do think there are aliens out there, some
    a lot like us, others not, but we're never going to make contact with
    them because of the physical laws we have. I think our Creator set it
    up that way on purpose. I do think that any "aliens" eventually
    appearing here will not be aliens at all but, like I said, demonic in
    nature.

    This space telescope that they are setting up might actually be able to
    detect such life, and if not that instrument some others, but as far as
    actual communication and interaction, highly doubtful.

    It is still just possible that very simple life exists on Titan and
    maybe more complex life exists on either Europa or Enceladus both ice
    skinned ocean worlds. Nothing like us but perhaps more complex than just coloured photosynthetic slimes in brine. Maybe chemistry around smokers
    rather than sunlight which is a lot weaker at Jupiter and Saturn.

    https://solarsystem.nasa.gov/moons/saturn-moons/titan/in-depth/

    https://solarsystem.nasa.gov/missions/cassini/science/enceladus/

    https://solarsystem.nasa.gov/moons/jupiter-moons/europa/in-depth/

    Of these Europa would be my first choice to look for life although any
    probe that visited would have to be very carefully sterilised to avoid contaminating that pristine habitat with terrestrial life.

    Finding just one other form of life anywhere would go a long way to
    settling various questions about abiogenesis.

    This space telescope that they are setting up might actually be able to detect such life, and if not that instrument some others, but as far as actual communication and interaction, highly doubtful.

    Detecting an atmosphere that is clearly out of chemical equilibrium
    would be a fairly reasonable signature of probably life. That was what
    made the methane detections in Mars atmosphere so interesting.

    It will certainly be a while before we have anything (even a probe)
    capable of interstellar travel but we could easily be a few billion
    years behind the technology of first generation star populations.

    It is just possible that we might get visited. We have been non-thermal
    radio bright for about 60 years now - that will attract some attention
    from any neighbouring civilisations with comparable radio telescopes.

    Who is 'we'?. You mean a bunch of theorists who went on a misadventure with timekeeping a few centuries ago and now can't even interpret a basic observation with real substance to it-

    https://sol24.net/data/html/SOHO/C3/96H/VIDEO/

    Physics is like an inverted pyramid built of an apex, it is founded on an assumption that you can make sense of the celestial structure at a local and Universal level by projecting the rotational characteristics into space as a substitute for orbital
    comparisons. Your clockwork solar system physics is giving you 'big bang' because the damn thing is built on RA/Dec-

    https://www.youtube.com/watch?v=BYy0EQBnqHI

    "And wherever anyone would be, he would believe himself to be at the centre.Therefore, merge these different imaginative pictures so that the centre is the zenith and vice versa. Thereupon you will see-- through the intellect.. that the Earth and its
    motion and shape cannot be apprehended. For the Universe will appear as a wheel in a wheel and a sphere in a sphere-- having its centre and circumference nowhere. . . " Nicolas of Cusa 15th century

    If you like something closer then try Pascal and Allan Poe-

    "Hitherto, the Universe of stars has always been considered as coincident with the Universe proper, as I have defined it in the commencement of this Discourse. It has been always either directly or indirectly assumed -- at least since the dawn of
    intelligible Astronomy -- that, were it possible for us to attain any given point in space, we should still find, on all sides of us, an interminable succession of stars. This was the untenable idea of Pascal when making perhaps the most successful
    attempt ever made, at periphrasing the conception for which we struggle in the word "Universe." "It is a sphere," he says, "of which the centre is everywhere, the circumference, nowhere." But although this intended definition is, in fact, no definition
    of the Universe of stars, we may accept it, with some mental reservation, as a definition (rigorous enough for all practical purposes) of the Universe proper -- that is to say, of the Universe of space. This latter, then, let us regard as "a sphere of
    which the centre is everywhere, the circumference nowhere." In fact, while we find it impossible to fancy an end to space, we have no difficulty in picturing to ourselves any one of an infinity of beginnings." Poe, Eureka

    If you want to try something older then Augustine-

    "Some of the brethren raise a question concerning the motion of
    heaven, whether it is fixed or moved. If it is moved, they say, how is
    it a firmament? If it stands still, how do these stars which are held
    fixed in it go round from east to west, the more northerly performing
    shorter circuits near the pole, so that the heaven (if there is
    another pole unknown to us) may seem to revolve upon some axis, or (if
    there is no other pole) may be thought to move as a discus? To these
    men I reply that it would require many subtle and profound reasonings
    to find out which of these things is actually so; but to undertake
    this and discuss it is consistent neither with my leisure nor with the
    duty of those whom I desire to instruct in essential matters more
    directly conducing to their salvation and to the benefit of the holy
    Church." St Augustine

    Congratulations! , by assigning relevance to daily circumpolar motion of the stars and tying it directly to the Earth's daily motion using RA/Dec, you have your 'big bang' right there. I suspect you won't wear a toothless grin, but you have certainly
    arrived at the end of physics and the ability to reason properly.

    _That_ we are going to "laugh at this" may be obvious enough.

    But the important question is _why_ would we laugh at it?

    The book "The Demon-Haunted World" by Carl Sagan addresses
    the issue.

    Some people are not Christians, because they see no evidence
    that religion is based on a real encounter with God, instead of
    the desire of some humans to control others.

    But many Christians have a more moderate and mainstream
    faith which doesn't involve expecting the end of the world to
    come soon, or considering demons as a real factor in world
    affairs.

    I wouldn't count anyone here remotely close to the research of the first Sun-centred astronomers and frankly, dealing with the unstable narrative inherited from the late 17th century is not as relevant or exciting as it once was. I could probably go over
    Sir Isaac's definitions of what he called absolute/relative time, space and motion as they refer to the antecedent research methods of Copernicus, Kepler, Brahe and Galileo but only then to undo the damage that was done.

    Copernicus had the main concept for a moving Earth in a Sun centred system right by correctly affirming that it takes a faster moving Earth overtaking the slower moving planets to account for their direct/retrograde motion and easily captured to day by
    sequential imaging-

    https://apod.nasa.gov/apod/ap011220.html

    He didn't have the resolution for Venus and Mercury, which is why Brahe had placed those two planets in motion around the Sun but retained an Earth-centred system.

    https://i.pinimg.com/474x/8d/53/a9/8d53a9ae498bc475ee557162b47177ed--tycho-brahe-industrial-revolution.jpg

    I changed this by getting rid of the background Ptolemaic framework that Copernicus, Brahe and Kepler had to work with and replaced it with a different set of references, most notably the demonstration of the annual change in position of the stars
    allowing for the Sun to exist as it actually does- a central, stationary reference for the purpose of explaining planetary motions within a solar system structure-

    https://www.youtube.com/watch?v=w2uCtot1aDg

    There is enough there for genuine modellers to work with and especially the incorporation of the solar system's galactic orbital motion and its influences on the orbits of the planets.

    If people choose to remain with the Victorian mathematicians and there inability to distinguish time from timekeeping then good on them.

    Even a thousand years is a long, long time at our level of science and technology. Think what has happened in the last century: relativity,
    quantum mechanics, QFT, thermionic emission, superconductivity,
    semiconductors, space travel. And there are still unsolved problems
    in physics:

    https://en.wikipedia.org/wiki/List_of_unsolved_problems_in_physics

    Many problems, like sending probes to the nearer stars, are merely technological, but other problems, like marrying GR with QFT are of
    equal or more difficulty.

    “Even from the beginning, inflation looked like a kluge to me… I rapidly formed the opinion that these guys were just making it up as they went
    along” -- Neil Turok

    It's possible that we're near the point of "complete" understanding, but
    this belief has been refuted before:

    "The more important fundamental laws and facts of physical science have
    all been discovered, and these are now so firmly established that the possibility of their ever being supplanted in consequence of new discoveries
    is exceedingly remote." -- A. A. Michelson

    Although Michelson did state that "our future discoveries must be looked for
    in the sixth place of decimals" is almost correct, but those minute disagreements become VERY important over megaparsec distances. And
    those niggles show our standard model may very likely be quite wrong.

    Sometimes I worry that Haldane had it right :-)

    I don't think the world's going to end soon. I think one has to be
    careful when they start touting "evidence" because you can go back to
    ancient times when they thought the world was going to end too.
    However, I live in the US and I do think some sort of collapse is likely
    within my lifetime. Too many uncorrected errors have occurred over many decades and the price is about to be paid.

    I actually lost a nearly lifelong friend a while back whose mother was a Christian (not sure he was). He stopped talking to me when I wouldn't
    take the position that our former President should be back in office. I
    think the mess goes way beyond any politician, although they haven't
    helped matters any.

    So, the US as we know it is likely to end soon, but that doesn't mean
    the world will.

    Now I do think demons are a factor in this world, especially if you
    attempt attracting them. I think it's pretty much common sense to stay
    away from the fortune tellers and cookies, weegie boards, and such.
    Just my opinion.

    I think in 100 year we will fully understand all natural law. We are
    very close to that now.

    We have no examples of complicated natural laws. Everything is
    astonishingly simple. The complexity we observe is a consequence of
    the infinite number of ways that those laws interact. The rules are
    simple. The systems those simple rules can produce are hugely diverse,
    and can be hugely complex. That's what technology exploits. And it's
    why modern science has entered a new era. Now that most of the
    underlying physics is understood, most science is about systems, which
    are studied using computer models and simulations.

    It is unlikely to strike you that physics went nowhere once they adopted the clockwork solar system (RA/Dec) framework so in a sense you are right, physics has come to an end because it never really began.

    "That the fixed stars being at rest, the periodic times of the five primary planets, and (whether of the Sun about the Earth, or) of the Earth about the Sun, are in the sesquiplicate proportion of their mean distances from the Sun...This proportion,
    first observed by Kepler, is now received by all astronomers; for the periodic times are the same, and the dimensions of the orbits are the same, whether the Sun revolves about the Earth, or the Earth about the Sun." Newton *

    I am delighted for you and your colleagues so model away with computer simulations all you like as I too model using computer graphics for interpretative purposes with a nod to the predictive side as well-

    https://sol24.net/data/html/SOHO/C3/96H/VIDEO/

    https://solarsystem.nasa.gov/planets/earth/overview/


    * In terms of orbital dynamics, there is no budget for the Sun around the Earth and the original Sun-centred astronomers would have laughed it out of existence. There was only the annual motion of the Sun through the constellations equating with the
    Earth's motion through the same. If you truly want to know what Isaac's absolute/relative time, space and motion represents as a rogue notion, then I suggest you start with Huygens-

    " Here take notice, that the Sun or the Earth passes the 12 signs,or makes an entire revolution in the ecliptic in 365 days, 5 hours 49 min. or there about, and that those days, reckon'd from noon to noon,are of different lengths; as is known to all
    that are versed in Astronomy" Huygens

    https://adcs.home.xs4all.nl/Huygens/06/kort-E.html

    Think of that as the Rosetta stone for unraveling Sir Isaac's grand misadventure with solar system research. Then again, you probably lost the most valuable thing you have- your curiosity.

    I suspect it could end up being heavily resource constrained by the
    planet unless someone finds a way to be very much more efficient at
    harnessing solar energy and recycling materials than we have been so
    far. Dystopian futures R Us doesn't look all that fanciful these days.

    We are still a very long way off realistically being able to exploit the resources of either the moon or Mars (or even mine passing asteroids).

    I agree that it is quite possible that beyond a certain point all
    civilisations may end up with the same laws of physics and technology
    limited then only by available resources (very finite) and imagination.

    OTOH every time you think you have solved physics some minor quirk in
    the Nth decimal place comes to light requiring new physics to sort it
    out. It could be that we can only every hope to make successively ever
    more accurate approximations to the reality of the universe.

    Fusion power has remained an illusive 50 years away from reality for
    about 60 years now and it continues to be very difficult to exploit.

    Fermi's paradox if intelligent life was common in the universe seems
    reasonable to me. Then again maybe H2G2 really got it right and rich
    kids aka Teasers appear in front of drunken yockels in the mid West.

    The zero-point field is hope and despair. Experiments confirm it but there
    is sufficient energy there to roll us up into a black hole and send us to the singularity. OTOH, it may be our salvation:

    https://www.scientificexploration.org/docs/12/jse_12_2_puthoff.pdf

    But that investigation doesn't seem to be going anywhere.

    And Alcubierre, etc. metrics? Way beyond our technology to investigate experimentally. And we are at a loss to explain time itself. SR and GR
    treat time and space on an equal footing, but

    https://royalsocietypublishing.org/doi/10.1098/rspa.2015.0670
    "Quantum asymmetry between time and space"

    https://newatlas.com/physics/quantum-time-theory-nuclear-reactor/

    And we may find out in a couple of years whether or not neutrinos are
    tachyons:

    https://arxiv.org/abs/1909.06048

    The best fit to the preliminary data places the neutrino mass-squared at
    -1.0 eV², meaning the neutrino may be a tachyon. By the error bars,
    there's only a 10% or less chance that it's mass is positive rather than imaginary.

    That will certainly cause some thinking about ... er ... causality.

    Don't you have a discouraging outlook on the future of mankind? Do you
    believe we'll even make it to 2122? :-)
