Science Squabbling

They are corrections to the non relativistic approximation, 1/2mv2. So they are just additional bits of kinetic energy.

Stop being a Jerk

Ha,
call me that again and I might just Jounce off in a huff.

Ooooo, the air is crackling with the tension...

Even a weasel
can Pop!

I can't find anything that actually corroborates that, I admit.

There is data on Markarian: https://www.nasa.gov/press/2014/august/nasas-nustar-sees-rare-blurring-of-black-hole-light

That looks like a made-up site to trick old people

It reads like a click bait or AI written site!

No reference to the actual press release = dodgy.

Though the original story looks good : https://www.ast.cam.ac.uk/content/black.hole.has.major.flare

And it's important to note this blob didn't come from inside the event horizon but rather the extended structure outside and around the horizon. Movement towards and away from the singularity is all good here.

That looks like a made-up site to trick old people

Yes, I admit that this is true, hence looking for another source.

However, I want to believe, as they say.

Optimism linked to longer lives. I really hope that this is true!

https://www.theguardian.com/world/2019/aug/26/optimism-may-hold-secret-to-longer-life-study-suggests

I have my doubts.

We're all going to suffocate in c02 or burn to death m8

On the other hand, if you're an orphan living in poverty with 6 degenerative diseases, you will probably a) be a pessimist b) die relatively young, and the pessimism isn't really your main problem

Indeed. This really isn't my area, and unfortunately the original study is not open access, but there are some conflicting statements in Guardian article:
"They ... compared lifespan for the most optimistic with the least, taking into account factors including age, sex, race, education, depression and other health conditions present at the outset", but also
"Most of the participants in the study were white, and few had low socioeconomic status – meaning more research is needed to see if the findings hold in other groups".

Here's the paper

Came across this when reading about heat death

https://en.m.wikipedia.org/wiki/Boltzmann_brain

In this physics thought experiment, a Boltzmann brain is a fully formed brain, complete with memories of a full human life in our universe, that arises due to extremely rare random fluctuations out of a state of thermodynamic equilibrium. Theoretically over a period of time on the order of hundreds of billions of years, by sheer chance atoms in a void could spontaneously come together in such a way as to assemble a functioning human brain. Like any brain in such circumstances, it would almost immediately stop functioning and begin to deteriorate.

...

Boltzmann brains gained new relevance around 2002, when some cosmologists started to become concerned that, in many existing theories about the Universe, human brains in the current Universe appear to be vastly outnumbered by Boltzmann brains in the future Universe who, by chance, have exactly the same perceptions that we do; this leads to the conclusion that statistically we ourselves are likely to be Boltzmann brains.

Probably a rather polite squabble but certainly one to debate: https://www.theguardian.com/science/2020/jun/19/cern-poised-to-back-plan-for-20bn-successor-to-large-hadron-collider

The successor to the LHC, Linear, Circular, Terrestrial, Orbital. Looks like the Future Circular Collider won the day, with a 6 fold increase in collision energy to 100 TeV

I hope I'm around for long enough to see it working...

hope I'm around for long enough to see it working...

I hope we're all around after it starts working 🕳 🙂

2050 maybe...

Still way short of cosmic rays...

Might have posted this in the wrong place...

This is a lie

You don't have to provide any information. You may not even need to log on. It's a fantastic resource, making research papers available to anyone and everyone, which is how it should be

I find the scientific publishing arrangement/business to be damn awful (haven't contributed to it for long enough...). University students shouldn't have any problem as they get ridiculous access through their library.

This reads like a press release about cannabis from the fifties.
