While the concepts outlined in the team’s new paper pave the way toward making travel through space nearing light speed a reality, constructing such an engine is likely something that will only be feasible far in the future, as the present state of technology would not allow for such a device.
The paper is paywalled and I am too lazy to look for a free/open link, but the shown graphs indicate many squared meters of energy concentrations of 1 - 10 * 10^39 joules.
The entire energy output of the Sun, in a year, is around 10^34 joules. 6.6 * 10^39 joules is apparently the estimated total mass energy of the Moon, if you basically perfectly E = mc^2 transformed it into pure energy.
In 2010 the estimated total energy consumption of humans on Earth was 5 * 10^20 joules.
So we just need something around ten billion * ten billion more joules than that, presumably generated by something i dont know, naval frigate sized?
Their theory of atoms was also that they were indivisible, being the most basic building block of all matter. Obviously now we know that that’s not true.
They described a lot of things, and were wrong more often than not. Their biggest contribution was really just progress in the scientific method itself.
It was not really what we would know as science, as it does not revolve around strictly constructed experimentation, hypothesis, or reproduceablility or predictivity, so much as it was the concepts of logic itself, of arguing about things with rationality and rhetoric.
A whole lot of Greek philosophy uses what seem like decent arguments to lead to decent sounding explanations that do not actually work if explored further or tested, though there are genuine examples of actual experimentation that still hold up fairly well, like Eratosthenes approximating the size of the Earth based on geometry and shadows.
Theyre basically just known for formally getting the ball rolling of inquisitive discourse on the nature of the world.
Basically, Empedocles came up with the 4 ‘roots’ of air (smoke), water, earth and fire, Plato expanded on how they ‘worked’ and interacted, as well as naming them ‘elements’, and Aristotle expanded further on this and added the concept of aether, which is what stuff in the heavens must be made of.
Probably the most popularly read material on this both in ancient times and today is Aristotle and Plato. Plato also associated the first four elements with Platonic solids.
Atomic theory of today is really only named such because Atom is roughly the Greek word for ‘indivisible’. Their indivisible atoms were of the four or five elements as they had no understanding of Chemistry.
Chemistry also linguistically does come from Alchemy, which comes from Al Khemia, which roughly in context means the study of the wisdom of Egypt.
This is because basically after Rome broke apart, many of the remaining scholarly texts of all kinds of philosophers largely only remained intact in Egypt.
So you had the Greek or Coptic texts translated into Arabic, studied and preserved in Arab speaking areas, which were then reacquired by various Europeans and translated into Latin or other local language. Roughly, the texts of this period which attempted to further philosophize more detailed understanding of elements, mixed with a huge amount of religious and superstitious content, became Alchemy.
When modern science began roughly with the Renaissance, well a lot of those guys were studied in Alchemy and attempting to apply more rigorous and testable logic to it, and we end up with the word Chemistry.
Thats a really long way to say that basically Atom as a word in modern parlance basically is just Greek for something that cannot be further divided, and is named such to basically honor the tradition of it all getting kicked off by the ancient Greeks.
Actual ancient Greek Elemental theory has basically nothing in common with modern Chemistry, and of course we now know that Atoms are actually divisible into Protons Neutrons and Electrons, and Protons and Neutrons are further divisible into various Quarks.
So if we could completely annihilate a mass equivalent to the Moon with an equal mass of antimatter and capture all of the energy with no losses to heat and without ripping the device apart, that would work?
… by an astounding margin.

Yeah. Faaaaaar off indeed.
Like Hippocrates telling people that a new breakthrough in medicine could allow bones to be seen in detail without cutting into flesh
Didn’t he or some other Greek philosopher also describe atoms?
Rudimentary atomic theory was independently “discovered” multiple times and places throughout history.
Hippocrates also described the four humors.

No problem, we’ll have it done next week.
