I went on a trip to Oslo and Bergen last summer. I'd love to go back; they're great places for mixing hiking and city exploration.

Inasmuch. It is the totem pole trench of words.

I think this would fall in to the latter scenario. 46 billion light years is the edge of the observable universe in the sense that light emitted by those regions has reached us by now. But these regions are beyond the cosmic event horizon, which is the distance at which light emitted now will ever reach us. That distance is about 17 billion light years.

Is there any point at which the distance becomes too large to the extreme where you basically get “deleted” from existence?

This is basically what the definition of "observable universe" is. It is the part of the universe that is close enough in space and time for light to reach us. So if you say they get transported to the observable part of the universe, then yes, their signals will eventually reach earth. But the closer they are to the edge of the observable universe, the longer the signals will take to reach, and the more red shifted they will be due to the expansion of the intermediate space as the signals travel to Earth.

Note that there are some semantics at play; "observable universe" might refer to the parts of the universe that have emitted light in the past that is reaching earth now. But the the light emitted by those places now might never reach Earth because they are now too far away. So if these astronauts got sent to one of those places then no, their signals would not reach earth.

I'd love to see more of this.

How is the definition of theft determined? Typically the definition is determined by the government. Why would the government define its own funding source as theft?

HIPAA allows medical care providers to share your information with each other for the purposes of providing care (whether that sharing happens through MyChart or some other means). It does not require your consent (and this could be a good thing if, for example, you were taken to a hospital while unconscious). You simply may not have a lot of options for preventing this. As NOT_RICK mentioned, you could opt out of Care Everywhere at the psychiatric hospital to prevent them from sharing your information that way. You could also try to amend their record or request that they restrict access to your records, as per https://www.hhs.gov/hipaa/for-professionals/privacy/laws-regulations/index.html#general. All of those options would require interacting with the original psychiatric hospital, so if you're unwilling to do that, I'm not aware that there are other options available.

Small correction, but this bit isn't quite correct:

If you go just below light speed, you’ll see the world outside go past like it’s being fast forwarded, and when you return, 8 years will have been compressed into something that seems much shorter to you.

During the time that you are just below light speed at a constant velocity, clocks that are "stationary" will appear to be moving slow to you. And clocks moving with you will appear to be running slow for a "stationary" observer. As I mentioned in a comment in another reply, the trip would feel short to you because the distance to your destination would contract to nearly zero. "Fast forwarding" (ie, having both you and a stationary observer agree that more time has passed on the stationary observer's clock) would happen during the periods of acceleration/deceleration at the beginning and end of the trip.

Sound cutoff issues (lemmy.world)
submitted 10 months ago* (last edited 10 months ago) by ProfessorScience@lemmy.world to c/pop_os@lemmy.world
 

Hello! I'm pretty new to pop_os and linux, but am trying to switch over from windows. I've been having some sound issues where it seems like sounds get cut off. It seems to most noticeable with something like doing duolingo from my browser (lots of short sound clips of words and such; if I click on words quickly, then spotify playing in the background will stop playing briefly). I've tried disabling sleep, as described by https://support.system76.com/articles/audio/, without luck. I've also noticed that I see errors listed in pw-top which sometimes correspond to sounds getting cut off. That is, sometimes I notice a cutoff without seeing an increase in the number of errors, but when I notice an increase in the number of errors it usually corresponds to something getting cut off.

Is there a way to see what the errors from pw-top are? Or suggestions for other things I should look into? I've looked at dmesg and systemctl status --user pipewire.service (and pipewire-pulse) but the only error I see is a nvidia-drm thing which seems to be innocuous. I've also uploaded my alsa-info results, if that's useful.
