Spacetime is a real concept in physics that combines space and time into a single framework. It is supported by evidence from experiments and observations, making it more than just a theoretical idea.
The Hendo hoverboard is a real product, not just a concept. It uses magnetic levitation technology to hover above the ground.
The "warp drive" is a ficticious device used in science fiction - specifically, in the Star Trek series. It is not a real device, and I don't think many details are published about how it is supposed to work.
As of current scientific knowledge and technology, there is no real time machine that has been proven to work for humans to travel through time. The concept of time travel is still theoretical and not yet achievable in practice.
The concept of the universe not being locally real is a topic of debate in physics. Some theories suggest that the universe may not exist in a fixed state at all times and locations. This idea challenges the traditional understanding of reality as being consistent and independent of observation. Scientists continue to explore this concept through experiments and theoretical models to better understand the nature of the universe.
Subspace is a concept in physics that refers to dimensions beyond the three spatial dimensions we experience. While subspace is a theoretical idea in some branches of physics, such as string theory, it has not been proven or directly observed. So, whether subspace is real remains a topic of scientific debate and exploration.

Night Court is a real thing, referring to a court that operates during nighttime hours to handle certain legal matters. It is not just a fictional concept.

The idea of a hole in the space time continuum sounds a bit like something out of Star Trek - but there are objects in astrophysics, both real and theoretical, which might match the description of a hole and which affect spacetime; such as a black hole, white hole, or wormhole. Black holes are shown mathematically to stretch the fabric of spacetime, causing length contraction or time dlation in accordance with Einstein's special and general theories of relativity. In this context, the term 'hole,' while notionally an entirely appropriate metaphor including the very real inescapability if you fell in, might be better interpreted as a 'severe stretch' as if space itself were infintely elastic rather than an actual break or gap in spacetime. White holes, which have not yet been observed, are also a consequence of Einstein's field equations from relativity theory and answer to a description somewhat opposite that of black holes, being a region of spacetime from which light and matter could escape, but nothing could enter, its event horizon being unreachable. The wormhole, also known as an Einstein-Rosen bridge, is a theoretical entity which could connect two distant points in spacetime somewhat like a tunnel - such that if you could travel through it, you might find yourself in another place in the universe or another universe entirely.

Avatar : The Last Airbender was just an concept based on the 4 basic elements of Nature. Its just a fantasy and not real. It talks about controlling nature's power which is not true in real life.

"Practical application" can best be defined by contrasting it to "theoretical application". A practical application is the real or tangible use of a thing or a concept, whereas the outcome of a theoretical application is nontangibe results not subject to objective measurement because the thing or theory has not actually been put to use.
The information about the theoretical tachyon particles is correct, although in the novel, they are not as theoretical as they are in the real world.

A real machine is a physical device with moving parts that may have friction and energy losses, resulting in reduced efficiency. An ideal machine is a theoretical concept that assumes no energy losses due to friction or other factors, resulting in 100% efficiency. Ideal machines are used for theoretical calculations and comparisons, while real machines consider practical limitations and inefficiencies.
