So... Light bounces off objects to reach our eyes, but, is it possible that a "Miniature Black Hole" could absorb the light that bounced off a certain object meaning it wouldnt reach our eyes?

Lets say I see a car, but then suddenly a miniature Black Hole appears which blocks the light from reaching my eyes, hence I wouldnt be able to see the car, could it really happen?

I read in the books that when A.C. is transmitted at high voltage and low current, the loss in form of heat is minimized. The books say that the H = I^2*R*T and hence, the power loss is minimized, if the current I is minimized. What I fail to understand is --- Why not use the formula H = (V^2/R)*T and say that the loss is more when V is more? (exactly the opposite conclusion!)

More precisely, When a step-up transformer increases V and reduces I, what happens to the formula V=I*R ?

How would it affect tidal patterns? what other effects would it have on the host planet? What about eclipses?

Im in the process of writing a Sci-Fi book and want the Sci portion to be in the very least believable if not factual as we today understand science and the universe

"The universe was not designed for life; in practically the entire universe conditions are extremely hostile to life. Saying that the universe is made just for us is like a frog looking at his pond and thinking that the whole world was made just for him."

I'm an engineer how works in the natural gas field and i've faced a proplem with a pool boiler water heater this problem is that the chimney of the boiler would be more then 50 cm in length (the max distance to the nearest wall) wich will might cause the gas to be cooled and the possibility to return back to the boiler, i have to increasae that horizontal length, what should i do, should i provide a thermal insulation or what, please advice cause it is very important?, thank you very much.

Please simplify this equation. I know the right answer is √3, but I don't know how to process it.

Please help me to figure out this question. Thank you very much.

Aero modelling is a very interesting hobby where you get a chance to fly your own air plane using remote control . However, aero modelling has its limitations and the plane a person usually flies and controls is not exactly the same as the real life plane.

The question I want to ask is, using the most sophiscated equipment available, eg, very accurate millers, cutters or even grinders, is it possible for us to construct a miniature version of a fighter aircraft to be used for aero modelling?

Can we create a miniature F16 or F15 aircraft that is exactly like the actual aircraft except in size? This craft should also be able to fly at Mach 2 and it should be able to manoveour well, like the actual fighter craft. It will also use fuel and it should be able to mid air refuel using a miniature mid air fuel tanker.

Of course, it is controlled by remote control by the user.
