Tbf, it’s not like physics stuff is always obvious, especially when dealing with relativity or quantum mechanics. It just feels obvious if you’ve already learned about the research that’s already been done.
It isn’t even remotely intuitive that light should have a max speed that can’t be added to by moving its source relative to other things. Plus, light does interact with matter, but it can only be slowed down by it.
So less a stupid question and more just one that isn’t educated about something.
Yeah yeah, I know. I was mostly just kidding. Everything is magic if you’re ignorant and we shouldn’t shit on people for not knowing something and props to them for asking and seeking knowledge and all that.
But it’s really sad that very basic science like radio waves which are introduced in 5th or 6th grade could be so completely misunderstood.
I remember my 6th grade science class having a lively 15 minute discussion about whether or not rockets can work in space since there’s no air…. We’re looking at videos of rockets working in space and then debating whether or not they do. 🙄

This feels a tad different than the person in the screenshot. Screenshot person fundamentally misunderstood how radio waves worked. Meanwhile, 6th grade you absolutely understood how rockets worked, at least to the level of understanding that they need air to work. Because you were right the whole time, those kinds of rockets can’t work in space without air. The slightly absurd solution that you wouldn’t readily know without a deeper understanding of how the rocket is built is that a rocket literally brings its own air with it!
Yeah- you make good points. I think what I was upset about was that we started with a given (they obviously work in space) and then half the class argued they didn’t for a while.
A better question would have been “how can they work since space has no air in space?” which leads to great q & a I think.
Quantum physics is not logical, every other field of physics is! Shame that instead of logic we are taught fucking equations, as if we could look up logical conclusions like equations…
Even less intuitively, the fan would increase the air pressure between the router and receiver, slowing light down slightly. So it would end up (imperceptibly) slowing the signal down.
This is not stupid at all. If Wi-Fi used matter instead of magnetic fields to propagate (like sound waves), a fan would affect it. Understanding magnetic fields is anything but intuitive.
Alternatively I would guess if fans improved the speed we’d have wifi fans throughout the house. Gaming wifi fans that sound like an airplane taking off with blinding LEDs
On the contrary, given the premise its a smart observation from an unknownledged person.
“Wifi is waves in the air” is very very wrong but as it appears it’s what this person was thought to believe. Given that they trust this information the conclusion makes perfect sense.
The only “dumb” here is whoever explain wifi like this to them.
So what the post really amounts to is. “I applied actual reasoning to the information i was provided as fact and my conclusion seemed strange, so i will ask on no stupid questions to figure out whats really going on”
More intelligent than the majority of internet users.
Not at all in this case though! Or rather, it depends on your perspective.
“Why doesn’t electricity leak out the outlet?” is a good question, if you know nothing about electricity.
“Why doesn’t electricity leak out the outlet?” is a little stupid, if you know a little about electricity.
“Why doesn’t electricity leak out the outlet?” is a great question if you know a bit more about electricity (because it does leak out, it’s just that 50/60Hz doesn’t couple to freespace well unless you have a colossal antenna).
I’m not sure if you’re being sarcastic but this is not true. Electromagnetic waves travel fastest in a vacuum, so the presence of air would slow it down very slightly and I would expect higher air pressure would slow it down further again only incredibly slightly because the electromagnetic waves would be traveling through a medium less efficient and more different than a vacuum.
Of course I’m making an assumption that you were using wireless signals. For all I know, you could have some weird acoustic link in which case you’d be absolutely right.
They would travel slower at high pressure and high temperature due to more interactions. Low temp and low pressure are the opposite. Sound is faster with high pressure and more complicated on temperature.
There are some stupid questions.

Yeah, what if I’m moving my router at the speed of light, not so intuitive now

Not everyone went to the same school, and not everyone went to school, for any number of reasons. I first attended a health class in college.

Agreed, it’s just someone trying to learn.

“I don’t know, can anyone help me learn?” gets so much respect from me. Incredibly powerful mindset.

I mean technically the weather influences your ping, since the waves travel slower at higher air pressure
Edit: Accidentally got it the wrong way around

Internet via carrier pigeon. A strong headwind will reduce your effective transmission time.
I believe this mode of communication was actually standardized.

Oh, wow. You really triggered them this time.
