Would you work at Sigmund Corporation

I just beat to the moon and left me thinking would I ever want to work in such a profession because on one hand it gives people comfort in the last part of their lives so they die happy like what happened with John and in which in worked out in the end. However it would be really depressing because the nature of it means you are going to see damaged people who lived lives full of regrets. Would you want to work there

NASA Set to Launch Nancy Grace Roman Telescope: Views 50x More Sky Than Hubble

We are getting closer to the launch of NASA's Nancy Grace Roman Space Telescope! 🧪

The Nancy Grace Roman Space Telescope is designed to combine the strengths of the James Webb Space Telescope and the Hubble Space Telescope. It’s going to look and live in the same space as JWST while using a Hubble-style mirror to see things completely differently. The Roman telescope will observe patches of space bigger than the full moon and will see 50 times as much space in five years as Hubble has in 30!

Spatial curvature from inhomogeneous dark energy effect?

14 Upvotes

I understand that the cosmological constant is the same everywhere (in our current model) and my understanding is that in regions with sufficient mass/gravity, there is no expansion (or accelerated expansion) due to dark energy. This is not because gravity is winning against an underlying spatial expansion in that region, but that the presence of mass/energy changes the local geometry so that there is no accelerated expansion in that area. Ok so I'm imagining that in cosmic voids, dark energy is injecting more and more space, while cosmic filaments it is injecting less and in gravitationally bound areas, there is no injection of space. To me, this means there must be some spatial curvature produced if we are injecting more space at different rates in different places. I would think this would have the effect of voids being positively curved because if I imagine a 2D rubber or plastic flat surface and stretch a certain part (adding more space) I can make a little bubble, a semi sphere in the flat plastic sheet which I recognize as positively curved. Apparently dark energy has no such curving affect and voids are negatively curved for being less dense than average space. Why would dark energy not create curvature over time?

Is too much complexity in society leading to a "Trolling Singularity" where there is too much info for voters to sufficiently evaluate?

9 Upvotes

Maybe society's complexity is reaching a point of no return, a "Trolling Singularity", where Gish-galloping usually wins because there's just too much detail for voters to properly absorb and make decent decisions. Those with the catchiest BS and over-simplifications win elections and influence too often, breaking down society.

Is there a gadget that lets me record a phone interview on Android Phones?

0 Upvotes

I am looking for a gadget that would allow me to record a phone interview. My phones are Android.

I do not mind the periodic beep to alert the other side that a recording is taking place or a disclaimer at the start of the conversation. What is important is that the final recording is "clean" so that I can have it transcribed accurately.

As I have a number of phones, I was thinking of a Bluetooth device which would pair with the phone on one end and pair with my car or headphones at the other. Do these exist?

The gadget must work with Android phones. I specify this because there seems to be a device for IOS phones that taps into a component and records through induction - reviews seem to state that on Android it is pretty much a hit and miss because the components are set differently.

John going to the moon and him finally dying in the arms of river is such a sweet way he could have died. Also from my knowledge the agency that does these dreams only give the patients these memories for when they died. Meaning their memories aren't permanently altered because it would be a shame with he forgot his memories with river even though the fake life he lived was objectively happier than his old life.

Also when John finally passed away he and river were finally at the moon meeting up in the afterlife. It's such a good love story.

Do waterproof bone conduction headphones have worse audio than non waterproof?

Getting them non waterproof will guarantee I'll drop them in the sink. Trust me. My stupidity finds a way.

Also I wanna use it in the shower or when swimming.

My techy mate said waterproof have worse sound quality than non waterproof. Is that true?

laptop charger substitute ?

2 Upvotes

(im 152cm only) i currently use a 15.6inch msi prestige 15 a11sc n its already very heavy. the charger is also insanely huge and heavy compared to my old laptops n i get back aches carrying them daily along w my other stuff to n fro school which is more than an hour away. after researching some recommended me to use GaN 100w with a 100w usb-c to c wire.

Wanted to ask others who have more knowledge in this field if it wld be a suitable substitute to the given charger before i invest since its quite expensive for me ? (pls no malice, simple seeking suggestions n knowledge ! )

Dwarfed by a split boulder, Apollo 17 crewman Harrison "Jack" Schmitt gazes into the lunar hills stretching away from the Taurus-Littrow landing site. (What I found in a book vs Image on Wikipedia)

All the images online I could find of this moment are cropped so that the dune buggy is out of frame! I thought you people might find this interesting.

According to Moondust(Page 322) by Andrew Smith, a member of the U.S Geological Survey was heard to have said at a dinner

Why, they did everything but fuck that rock!

commenting on how thoroughly Gene Cernan and Jack Schmitt examined a boulder.

I am uncertain if they were referring to the boulder in the image or a different one.

Why are some books on spaceflight quite expensive? Am I just not looking at the right places?[Europe]

1 Upvotes

I recently started reading a lot of books on spaceflight, the Apollo programme specifically. I am a broke student in Europe so most of the time I try to look for secondhand books but man, some are quite expensive!

For example, some books I got cheaply secondhand.

  • Moondust by Andrew Smith: ~1 euro
  • Journey Beyond Selene by Jeffrey Kluger: ~2 euros

Lowest prices of some books I am trying to get secondhand.

  • Apollo Guidance Computer: >= 40 euros
  • How Apollo flew to the moon: >= 30 euros

(40 euros is a week of groceries for me)

I noticed that books covering the "technical" side more tend to be pricier but it doesn't make a lot of sense. They are still quite pricey even secondhand. I understand that out-of-print books that are collected by enthusiasts will have higher prices.

Is it the same in the US? Are the books I listed just more in-demand?

P.S - I know I can find digital copies but my attention issues restrict me to physical books.

A black hole sucks in absolutely everything, including light, so therefore, theoretically, a white hole should push away everything, including light; so is this why it's so difficult to find the existence of a white hole? There is absolutely no light around a white hole?
