Could dark matter be decaying… into dark energy?
https://bigthink.com/starts-with-a-bang/...rk-energy/

KEY POINTS: On the largest cosmic scales, it isn't atoms or light that dominate the behavior of the expanding Universe, but two invisible, energetic components: dark matter and dark energy.

Over the past 7 billion years or so, dark matter's energy density has dropped precipitously, while dark energy has become relatively more important, with the latter now dominating the Universe's expansion rate. Could this be because dark matter is decaying away into dark energy?

It's a wild idea, but one that can be scrupulously scrutinized for its scientific merits. We don't think so, and here's why... (MORE - details)


Could the double-slit experiment finally be solved?
https://thedebrief.org/could-the-double-...be-solved/

EXCERPTS:  . . . the double-slit experiment has intrigued physicists for decades [...] However, only recently have researchers at the Vienna University of Technology (TU Wien) found a way to fully validate this experiment, using a particular measurement method on the particle.

“Our measurement results support the classical-quantum theory,” explained Sponar. “The novelty is that one does not have to resort to unsatisfactory statistical arguments. When measuring a single particle, our experiment shows that it must have taken two paths at the same time, and quantifies the respective proportions unambiguously.”

This study offers more information about the process behind the famous experiment and allows for further research to help advance the field of quantum physics... (MORE - missing details)
Double slit experiment - nice one CC.
There's a less click-baity summary here:

and (I think) the paper here.. (a freebie):
https://journals.aps.org/prresearch/pdf/...h.4.023075

I'll say what I got out of it (the summary) ..
Rotating the neutron in one path 'just a little bit' doesn't give accurate which way information but the detected neutron has 'some' rotation. By comparing the 'some' rotation with the original you get how much of the neutron went which way. So (for example) 2/3 'of it' went one way and 1/3 went the other. With hindsight maybe it's obvious but actually having it as an experimental result is stunning.
