Okay I did the same calculation but with Martian orbit as dyson sphere size, and 50% efficiency I got a wavelength of 3.4um so nicely in the infrared range of JWST.
I think the sphere would need to be like 99.95% efficient to be undetectable by JWST at Martian orbit radius.
Edit to add disclaimer: this is shitpost level math here guys, I’m just spitballing.
It would definitely emit thermal radiation. if it was 99% efficient and the size of pluto’s orbit, around a star like the sun, and the energy was used to create matter, I think it would radiate the remaining energy as 0.009 W/m2 with a peak emission wavelength of 150micrometers. The James Webb telescope has infrared capabilities that max out at 28.5 micrometers so def not detectable.
But probably a dyson sphere would be smaller than pluto’s orbit, which would greatly increase the apparent power, and shorten the wavelength. idk it’s all imaginary.
I won’t subject you to my hand writing but I did (power of sun × 0.01)/(surface area of sphere with Pluto’s orbital radius) to get radiation intensity (0.009 W/m2). Then rearranged Stefan-Boltzmann law to solve for temperature (19.8K). Then used Wien’s Displacement Law to calculate the peak wavelength (1.5×10-4 m).
Maybe I’ll run the numbers again with a martian orbit radius, and 50% efficiency.
Like I’m sure it’s not but I don’t know if it’s a worse explanation than any of the other ideas being considered. But I don’t know enough to even know how wrong I am.
Is dark matter just Dyson sphered stars?
What unhealthy eating habit are you indulging in at 21:45?
I don’t think anybody is suggesting that Tesla had a sign that says “heil” in Tesla’s font manufactured and installed on their factory next to their name. It’s a projection by a protestor to draw attention to Musk’s Nazism.
Can you elaborate?
I think his complaint is that he lives outside the boundary (on 61st at 5th) but that because of one way streets he is forced into the tolled area even if he wants to go the other way.
Downvote away but you know it’s true.
You don’t know what others know. Building codes vary tremendously between regions. Imo zoning and real estate speculation are MUCH more significant drivers than the cost of design and construction. But my opinion is based on my experiences in my region.
Yeah I thought the same about depose.
It seems he bought Twitter and successfully traded twitter’s market cap into right wing populist influence (RWPI) [and presumably a capital gains deduction], and now RWPI into governmental influence.
Melania Trump too right?
Yeah,
A woman at a party hoping to bag a dying rich husband retains the right not to be groped/assaulted or raped.
I actually wouldn’t be surprised if the modeling industry as a whole was proved to be a sex abuse conspiracy from the get go. Like create this image in the media of beautiful women becoming glamorous successful models that marry dying billionaires, tell them that they have to network at fancy parties where the industry moguls are, convince them to ingratiate themselves to the moguls however they can…
I think its like any other utility (water or electricity or methane) except that you pay for the generation separately. So imagine that for electricity you pay a service fee to the grid operator to keep your connection capable of a certain amperage, and you separately pay the hydroelectric dam for the power you use.
ISPs are the grid operator saying, yes you pay for 200 amp service but you’ve already bought enough power this month. Don’t run your AC for the rest of the month.
Pretty interesting!
The Wikipedia article has a ton of info. This magazine article which Wikipedia references is imo a better introduction https://knowablemagazine.org/content/article/technology/2022/cochineal-red-dye-bugs-moves-lab
Ateam has managed to bioengineer a fungi to produce it, but with very low yields. Another team has managed to get e coli to produce it, they estimated that a 100,000 L fermenter could produce the same amount as a hectare of land.
100,000L is 100m^3 which is a cube with 4.7m side length. ~15’x15’x15’ or uhh ~~~the size of 4 F150s.
Edit to add: a hectare is 100m x 100m ie ~100 yards x 100 yards.
Yes this this is clearly a picture of an empty bus at 2AM when nobody is trying to get anywhere.
Yeah that sounds like what was explained to me
I needed to upgrade my modem because the isp capped the speed of docsis 3.0 modems to like 75Mbps. I remember being quite upset because I was previously getting 125Mbps service on the same modem. I seem to recall there was a quasi legit technical reason for it though.
It’s not, but it seems Argentina doesn’t think people should be allowed to own their phones.
I was told there was no such thing as a shortage in a free market, why won’t the executive branch embrace free market economics?
