I have had another go at growing salt crystals. This time I dissolved a quantity of pure Sodium Chloride (NaCl) in to water using a conical flask, then poured this solution in to a glass dish and left for about 2/3 weeks.
Eventually all the water evaporated away, leaving crystals behind. Using my USB microscope, I found and took a picture of some that had grown in to a nice cube shape.
I have taken another photo using the USB Microscope and also included the calibration / measurement sheet in the photo to try and illustrate crystal size.
Please see Mastodon post for details.
Physicists suggest that black holes could have an exit to other places in the universe
Interesting article from Meson Stars regarding black holes having possible exits. I have included a paste of my Fediverse comment below. However feel free to discuss on Fediverse or on Science forums.
This does make some sense, I have heard about white holes, which are the opposite of black holes as they allow matter to be ejected in to space. This seems to tie in with the suggestion in the article that if you could pass through you cannot get back again. However in relation to this
"Scientists have already said that all matter inside a black hole is destroyed, "
I got the impression matter can't be created or destroyed, it is interchangeable with energy. In which case, could it be that matter is drawn in to a black hole, somehow converted in to energy then ejected from a white hole?
So purely on a speculative idea
So how do we find these white holes, perhaps we have already found them as we can detect things like gamma ray bursts or neutrino emissions but can't always explain them, perhaps these are related to white holes and we are observing the release of energy in to space as these or similar phenomenon
Halogens and the ozone layer
Interested research posted on Phys.org looking at Halogens and tropical region ozone depletion
Extraterrestrial life paper from phys.org
Another interesting paper on extra terrestrial life. I was not aware of the term 'Terminator Zone' till today. Posted to fedi by
Mikko Tuomi : @email@example.com
I will see if I can download the paper, and add it to my reading list, but we are learning all the time.
So looking at the “terminator zone,” which is a ring on planets that have one side that always faces its star and one side that is always dark. “.
New Science discoveries 1
Something else found on the Fediverse. This was posted by Science Alert. The links should work from here too, if not you will need an account on a Mastodon instance. So lots of interesting things happening

Magnetic fields on cosmological galaxy mergers
This is an interesting paper on Archive. Looking at how magnetic fields and galaxy mergers.
I have added links to the thread on the Fediverse, and provided a link to Science Forums for further discussion.

Search for gravitational waves set to resume
Search for gravitational waves set to resume following COVID-19 setbacks
Physics world have reported that the The LIGO–Virgo–KAGRA will resume. They are looking for gravitational waves. You can read the full article here. Back in 2021, there was a talk at FOSDEM about Virgo which I made a post about on 7/3/2021.
There is some info on Ligo at the STEM group, which I can re-display if anyone is interested.
On this day in History : Diana Project
I guess this could also be seen as the beginning of radio astronomy once we learned we could get signals outside of the ionosphere.
