My friend and I were talking about power requirements in loudspeaker design and the fact that almost all of the power is required to drive the woofers and move lots of air. ...
I think i've discovered something important in the field I dabble in as a advanced hobbyist. Like this was a breakthrough and perspective shift enough for me to stay awake all night into the morning until I had to go to sleep testing it works and boilerplating the abstract paper. I constructed a theoretical framework, practical ...
Heat is a form of energy right? So if we take away the energy from the Air we have concentrated some heat elswhere which we should be able to harvest? So i ask myself why are Air conditioners not a source of energy?
In movies it is shown that through polygraph test it can be found whether a person is lying or not. But we all know that it is not correct. What I am asking can the polygraph test be modified, more data collected so that it becomes more accurate ? Also is there any alternative to polygraph machine to find whether a person is ...
This summer and last I started feeling the bite of mosquitoes, like, not the itch, but the moment they "bite". Like a thin shot or a thin plant spike but more than fiberglass. Is there an evolutionary or environmental change to mosquitoes happening, or am I becoming immune to their numbing agent? What's happening?
I understand why we can't see stars during the day: the sun illuminates the atmosphere and effectively blots them out. But why can't we see low earth orbit satellites, which are not exactly "outside" the atmosphere? If they're inside, shouldn't we see them reflecting sunlight back to us?
I've been hoodwinked too many times by well-reviewed pop-sci books which I later discovered to be hated by the actual scientists who do the work. Quantum Supremacy by Michio Kaku was the final straw 😆 ...
I just watched a Geology Hub upload on the Cerberean Caldera super eruption in what is now Australia. It happened over 300 million years ago, but in terms of the total age of the planet, even 300 million years is a relatively tiny blip. So have there been any significant epics to truly say events like x, y, or z will never ...
Wherever there is matter in an ever-thinning universe, there might be an entire cosmologically-sized era dominated by an entirely different chemistry to what we have now.
Maybe this should be in Nostupidquestions as I'm aware the moon exists. And I guess there may be an orbit zone where things tend to remain in orbit. But curious... ...
Theoretically space is infinite, as it is the ultimate container. So how does it expand? For example if you keep adding objects to a room the room isn’t gonna expand, you’re gonna run out of space. So how does space expand if the cause of it is apparently dark matter being created?
If Aliens came to Earth, would we not have as much of a language chellenge as they would do with us? Also like in Mars Attacks how would we know that we aren't saying lets go to War?
I don't know if this is the place but some people did the science of what The Flash would have to eat to maintain speed. Has anyone in science ever did the math on how super heroes can fly?
Temperature based Reverse Entropy Machine?
So, obviously there's a mistake in my reasoning somewhere. Maybe I've pointed it out already I'm not sure. ...
Do basses exert more energy in talking than sopranos?

According to current science what is the theoretically most tiny form of minigolf that could be made?
Do we have the technology to play minigolf using subatomic particles? ...
What are the next steps I need to do to publish a paper somewhere like arXiv?
I think i've discovered something important in the field I dabble in as a advanced hobbyist.

Why do AC's not produce energy?
Heat is a form of energy right? So if we take away the energy from the Air we have concentrated some heat elswhere which we should be able to harvest? So i ask myself why are Air conditioners not a source of energy?
Can an electron-positron pair become entangled? And since the positron behaves as if moving backwards through time, are these particles entangled as if at different points in time?
Why isn't Near Death Experience research taken more seriously?
So forgive me if this topic borders too much on religion, but this is something I've never understood. ...
Can the polygraph test be made more accurate ? Has anyone made a polygraph machine or any kind of machine that can detect whether a person is lying or not ?
In movies it is shown that through polygraph test it can be found whether a person is lying or not. But we all know that it is not correct. What I am asking can the polygraph test be modified, more data collected so that it becomes more accurate ? Also is there any alternative to polygraph machine to find whether a person is ...
Why am I suddenly feeling mosquito needles?
This summer and last I started feeling the bite of mosquitoes, like, not the itch, but the moment they "bite". Like a thin shot or a thin plant spike but more than fiberglass. Is there an evolutionary or environmental change to mosquitoes happening, or am I becoming immune to their numbing agent? What's happening?
Matter/ dark matter/ anti-matter relationaship
We know pretty well what matter is and how it interacts with the others. ...
Why can't we see low earth orbit satellites during the day?

Could Venusian greenhouse gas effects keep a TNO like Pluto warm?
TNO = trans neptunian object, basically far out dwarf planet ...
Whatever your field of expertise, are there any popular science books you'd recommend that do a good job of presenting it to the public?
I've been hoodwinked too many times by well-reviewed pop-sci books which I later discovered to be hated by the actual scientists who do the work. Quantum Supremacy by Michio Kaku was the final straw 😆 ...
What hard evidence is there to establish geologic epics or do they even really exist?
I just watched a Geology Hub upload on the Cerberean Caldera super eruption in what is now Australia.

So Hi everyone, first of all let me just say sorry if u can't get my writing 😭. ...
As the universe expands and cools down closer and closer to absolute zero, will Bose-Einstein Condensate become the predominant form of matter?
Wherever there is matter in an ever-thinning universe, there might be an entire cosmologically-sized era dominated by an entirely different chemistry to what we have now.
Is remaining in geostationary orbit an active process?
Maybe this should be in Nostupidquestions as I'm aware the moon exists. And I guess there may be an orbit zone where things tend to remain in orbit. But curious... ...

Are these three statements true: ...
Realistically, how much power would Valve's Portal Gun require? How heavy would it be? And how would cooling work with it?
How is space expanding?
Theoretically space is infinite, as it is the ultimate container. So how does it expand? For example if you keep adding objects to a room the room isn’t gonna expand, you’re gonna run out of space. So how does space expand if the cause of it is apparently dark matter being created?
