Five hundred years or so ago, 'n aansienlike aantal mense het gedink die wêreld is plat. In 500 jare se tyd, watter huidige wetenskaplike teorieë na dieselfde vlak gedegradeer sal word as wat die plat Aarde-teorie nou is? Richard Cutsforth, Chichester

String theory. Too weird and inelegant to possibly be right. PrincessWhatever
I would say “dark matter”. Science can’t possibly measure the mass of all the matter, or the various forms of energy present in the visible universe, so they invented a “magic matter” to fill in the blanks. reinhardpolley
How about the big bang theory? It’s just a theory, is it not? The universe might just as well have been created by a burp from an ancient intergalactic hedgehog. UnironicBeard

I have a sneaking suspicion that, in 500 jare, humans will have proved that intelligence does not reside in us.
We have a planet tailor-made for the survival of all life on the planet, including ours. Ten spyte daarvan, we have humans destroying ecosystems in search of wealth and humans killing humans in search of control.
I think Crocodile Dundee said it best: “See that rock over there? It’s been there for thousands of years. Arguing about who owns it is stupid.”
That’s the metaphor that describes humanity today, as smart as that rock is. Rcamejo
We must dismiss the idea there was a widespread belief in a flat Earth 500 jare terug. An interesting and sometimes surprising window on educated medieval perspectives on the cosmos is provided by Dante’s The Divine Comedy, written during the early years of the 14th century and entirely conceived within a spherical-Earth model of the universe.
Hell is a huge funnel-shaped structure, centred under Jerusalem, descending tier by tier to its deepest point, which is located at the centre of the planet. Purgatory is an oceanic island in the southern hemisphere, at the antipodes of Jerusalem.
Dante frequently makes reference to, byvoorbeeld, how midday on the Tiber equals sunset on the Ganges. Most remarkable of all, when Dante and his guide, Virgil, descend to the deepest pit of the inferno, where Satan stands waist-deep in a frozen lake, and they continue their journey by climbing down Satan’s shaggy pelt into a cavern below the lake, Dante is dumbstruck suddenly to find himself alongside Satan’s gigantic legs, which are now upside-down.
Virgil patiently explains to him that he should not be surprised, as they have passed the centre of the Earth, to which all objects are drawn by gravity. Uppsalaman
Neoliberalism is a theory well beyond its use-by date now, never mind in 500 jare se tyd! DiogenesPithos
Materialism: the weird idea that consciousness somehow emerges from matter. PlatonicThoughts
It’s not so much a matter of what will be (dis)proved, but what will be acceptable. Back in 500BC, Pythagoras postulated that the moon and the Earth were spherical, based on observation and logic. Toe, in 240BC Eratosthenes noted that, at midday in one town in Egypt, the sun shone directly down into a well, whereas, at a distant town, at the same time of day, the light arrived at an angle. He used this, and the distance between the two towns, to calculate the diameter of the Earth – and made a pretty good fist of it, ook.
How did he measure the distance between the towns? This was in the days before Google Maps, so he paid somebody to walk between the two towns and count how many paces it took. That is the painstaking attention to detail, and the endless quest for truth, that epitomise the scientific method.
Did the wider world pay any attention? Geen, because it didn’t fit in with the extant received wisdom that the Earth was flat, a “fact” that was obvious to anyone who looked at the horizon.
Then along came Copernicus en, natuurlik, Galileo, whose heliocentric models contravened the doctrine (and dogma) of the all-powerful church. The church ignored their postulations and proofs and insisted on its own – totally unproved – “model”. That is the painstaking attention to superstition and control of the masses, and the endless quest to suppress inconvenient facts, that epitomises virtually all major religions.
So, it’s not a matter of being right; it’s a matter of being accepted. Maybe the best we can hope for is that, long before 2521, humankind (if it still exists) will have outgrown the need for religions. LewisWinders
Almost none of the above is actually true. In rejecting Galileo’s model, the church was siding with the majority scientific opinion of the day. There was not, as yet, sufficient evidence for heliocentrism. Geocentrism wasn’t a simple superstition, but a well-established system that was able to predict astronomical events quite accurately. The Catholic authorities believed, quite reasonably, that as long as it did that then there was no reason to reject it. Galileo’s own definitive proof of heliocentrism – that the tides are caused by the Earth sloshing about in its orbit around the sun – was, natuurlik, not only unconvincing but flat-out wrong.
Moreover, much of the evidence supporting heliocentrism was gathered over the course of the 17th century by Catholic astronomers, particularly Jesuits, who were as committed to evidence-based science as any hard-nosed atheist. JonathanCR
Science cannot find a proof for time; there is no experiment that shows that time exists. As a fairly rudimentary aspect of our lives and a fundamental aspect of all applied mathematics and sciences, it might be nice to solve that one.
I’m working on a theory that a fitted sheet obeys neither Euclidean or non-Euclidean geometry. Here’s looking at Euclid. flinders
1) That capitalism is a valid – and in any way morally acceptable – way of structuring our economic activity and distribution of resources. To paraphrase Captain Picard: “Our 20th-century ancestors, with their primitive economic systems!”
2) That nation states are a reasonable structure in which to invest sovereignty.
3) This one may be wishful thinking – the idea that the speed of light is unable to be exceeded. If the idea is klank, I hope the Alcubierre drive or something similar is plausible. The idea that we will never be able to explore the rest of the universe is one I find crushingly depressing. BostonMatt
The theory that time travel is impossible. I’ve just nipped back 500 years from a post-Covid world to post this comment. FYI, the scientists ran out of Greek letters before we got to the “new normal” in the 2030s. galvinonthewing
Five hundred years? By then, I suspect there will be a plethora of theories about the ancients (or aliens) who built cities and mastered arcane sciences such as manufacturing glass, flying machines and creating artificial light, along with generating and transmitting energy. Then there will be the inevitable fables about what happened to them. AwakenstoEmptiness
