This article lays out some of the reasons why we think there might be one. Also, we've seen unification happen in the past. First, electricity was linked to magnetism by Oersted when he noticed that an electric current made a compass move (I believe he actually noticed this during an in-class demonstration). Until then, there was no reason to think that static electricity had anything to do with compass needles pointing north. Then, EM was united with the weak force at high energy back in the 70's. There are indications (more details in the article) that there are some strange coincidences in various values for strong, weak, and EM strengths/gauge groups that hint at the three forces becoming one at energies 10^15 times the mass of the proton.

An imperfect but perhaps useful analogy is the Higgs boson. Even though it had never been seen, a lot of stuff made a lot more sense if the Higgs existed, which is why we spent billions of dollars building the LHC, and indeed the Higgs was there.

This is where my knowledge fails, but I think it's safe to say that different chemical and filtration processes activate between different classes of in-taken nutrients including water, and these are handled by different organs in the body.

The intestines do much of the work of digestion for more complex molecules, giving those molecules time to be broken down into protein building blocks, and simplifying starches into sugars. But if you drink a couple big glasses of water, most of that water never reaches the full path through them.

In the town of Xanten, Germany, there's an "archaeological park" (Archäologischer Park Xanten) at an old Roman fort. Most of what's left are stone columns and foundations that had minimal restoration to keep them from falling apart further, but they rebuilt much of the town as a great educational attraction. It's also my understanding that many of the great stone edifices were, upon the fall of their empires, pillaged for building materials and road paving. The Goths didn't really have historic preservation on their list of priorities.

The gnu file utility can read the first few bytes of a file as a magic number to determine what kind of file it is.

There is a hacker magazine called POC or GTFO, meaning proof of concept.

The PDFs of that magazine can also be interpreted in various other ways. Files that you can do this with are called polyglots.

The Ottoman Empire was the universally recognised legal authority for Greece at the time. Ipso facto it was legal. Like I said, whether you morally agree with the position and whether Greece should have been ruled over by the Ottomans is another matter. It was however legal at the time the deal was done and the marbles were acquired legally.

Many of these places are zones of historical conflict and that is a cause. Rome defeats Carthage and tears the place down, that in ancient times. Several sieges in documented historical times cause much damage to the Parthenon, and other sites.

I think this answer, whilst partially correct, kind of misses the bigger picture. Medieval and Modern societies did have the resources for this kind of monumental building. maybe not as many but they certainly did. They just used those resources building things that were useful to those societies, namely churches and cathedrals. The later Middle Ages and Early Modern period saw a massive expansion in the construction of monumental structures like Notre Dame or Cologne Cathedral. As admired as the Romans were the were admired by Medieval and Early Modern people for their vast empire and Christian piety. Pagan temples and arenas for blood sports had largely gone out of fashion before Rome even fell, what purpose would later people have to maintain those ruins?

So whilst you are correct that later societies couldn't marshal the same resources for monumental constructions as the Romans could, it is not really the most significant factor in my estimation.

Almost all of these structures were used as a source of building materials. The most obvious is the marble cladding from the exterior, and bronze ceiling from the portico of the Pantheon. The marble cladding was stripped by lime burners in the middle ages, and the bronze ceiling from the portico was stripped and melted down by Pope Urban VIII in the 1600s. The main temple of the Parthenon complex was largely intact until 1687, when the gunpowder magazine stored there by the Ottomans was hit by cannon fire from the Venetian Navy and exploded.

PM_ME_YOUR_THEORY t1_je5bm7k wrote

They don't know. It's a belief based on what they take to be the structure of the Universe. It's debated topic within Philosophy of Physics and even within physics itself.

This belief comes from the fact that everything, so far, seems to be describable and connected mathematically. The problem is that in recent years we have seen that the physics that describe the nature of the very small seem to be different from that of the very big. This means that either i) we simply haven't found a way to connect both properly; ii) it isn't possible to connect both properly; iii) the fundamentals of our understanding of the universe are still somewhat incomplete.

Water-Cookies OP t1_je5bbm7 wrote

So, when you chug water during your meal, the stomach "knows" to pass that on faster, even though it's now mixing with the chyme and potentially creating a diluted concoction?

It makes sense that liquids are processed faster, it must just have to do with receptors in the stomach recognizing that there is water present and to just let it pass, for lack of a better analogy.

They don't. It is how science works.

There are gaps in our theories where they don't meet up to suggest that these current models are incomplete or insufficient. There is no clear signpost that ever says "you've got it all". So new models and theories are developed and new experiments are made.

Some theories we definitely don't have the experiments to test (today). So they might remain unconfirmed for a while yet.

And even if a "next step" is ever found, there is no guarantee that these next steps don't point out even more things to discover.
