New tachyon study could unlock the secrets of time travel and reality

Interesting article published on Europe Says. I have asked on Mastodon where the link to this was posted, that if Tachyons have mass, if this should be factored in to the missing mass, which I think we are suggesting is filled with Dark Matter. So, another part of the hidden universe that has some mass. We are trying to account for where all the mass is located.

I don't fully understand the physics behind all this though.

To me, this is what AI is meant to be used for, taking data and helping scientists sort through this and make meaningful conclusions based on data and interpretation of data.

The CMS collaboration presents a new search for the decay of a Higgs boson into charm quarks, bringing physicists closer to unravelling how this unique particle endows matter with mass [1]

More interesting findings about the early universe, I guess some of this makes sense as one of the 4 fundamental forces is Electromagnetic forces.

This research findings are detailed here. So if I understand this correctly, the early universe processes had that were had electrically charged dust particles, these produced magnetic fields as they moved around by the radiation from the 2nd generation of stars.

There is a related paper on arXiv on this research.

Update 13/1/2025 – a related or seemingly related discovery

• Detection of magnetic fields in superclusters of galaxies

Just sharing this as it appeared in their Mastodon post.

MPI for Gravitational Physics @mpi_grav@astrodon.social

As a reminder, today is the last day of our female researcher portrait to celebrate the International Day of Women and Girls in Science!

But until the end of the month, we will be sharing our colleagues' advice for young women, their paths to physics, and their visions for the future.

This is quoted from a Mastodon post from the MPI for Gravitational Physics

Last night, the two @LIGO detectors observed the second gravitational-wave candidate of the day.

The possible signal with the preliminary designation S250205ee most likely originates – if it is real – from the merger of two black holes.

It occurred at a (luminosity) distance of 9.4 billion light-years.

This brings the total number of significant signal candidates identified in the fourth joint observation run of the international detector network to 190. One (GW230529) has already been fully analyzed and published. The others will also be carefully examined and then published if confirmed.

So back to some Physics videos, what is space-time?: This video does a really nice job of explaining this in a way that is understandable, but not so simple it loses any meaning.

I decided to sign up to another free open learn course with the Open University. Unsolved problems in cosmology is an extract from a level 3 course, S385 Cosmology and the distant Universe.

After studying this course, you should be able to:

• understand the basis of modern cosmology based on the hot big bang
• summarise the main candidate dark matter particles, and the prospects for directly detecting them
• compare models to explain the late-time acceleration of the Universe's expansion, i.e. dark energy and the cosmological constant
• discuss observational prospects for understanding the nature of dark energy
• explain the theoretical problems that led to the theory of inflation, how an early inflationary period solves them, and how researchers are investigating inflation.

Future space telescopes could be made from thin membranes, unrolled in space to enormous size

Interesting article on the future of space telescopes so the idea seems interesting as it allows deployment of large telescopes in space quickly.

The JWST is 6.5 meters, the ELT is 39 meters (ground based) as the JWST is foldable then the technology is already there.

This could offer some real opportunity to make strides forward, as we have seen with the JWST. Larger telescopes allow for the collection of more light, I would guess that telescopes can be built to collect different light e.g. UV, Visible and IR.

Should be good.

Black Hole Tears Star to Shreds, Unleashing Cosmic Shockwaves

This is interesting, I will add a link to NICER (see article) to the links page.

Black holes seem really complex, and there is probably much more to learn. It is also worth watching the two videos as a further explainer to the research and the resulting paper.

So this is looking at a black hole, and how it is interacting with a local star trapped within its gravitational pull, As the star is pulled apart, some of the matter becomes a disk around the black hole, however this matter is then also interacting with another star.

If I understand the paper or at least article, this event links tidal disruption events * and quasi-periodic eruptions, helping astronomers understand black hole environments and shape future research

• The above link is to Wikipedia, as this is NOT an academic source of information, please use a different source, link is for reference only

On an unrelated note, according to the Solar System series by Professor Brian COX, Rings have formed around planets when an object such as an asteroid gets caught in the gravitational pull of the planet, Moons are also objects that have been caught up.

I am not sure if the two phenomenons are related in that stars being ripped apart by a black hole are a similar event, just on a much larger scale.

According to MIT there have been other similar events detailed here
