Is BEC still considered a viable dark matter candidate.

AI Thread Summary
Bose-Einstein condensates (BEC) as a dark matter candidate have not gained significant traction despite initial proposals. Current popular models focus on Weakly Interacting Massive Particles (WIMPs), with the Xenon100 experiment nearing the capability to detect or rule out these particles. If WIMPs are not detected, it could lead to a reevaluation of dark matter theories, potentially increasing interest in alternatives like BEC. The timeline for results from Xenon100 is anticipated soon, with discussions about the future role of the more powerful Xenon1T experiment. The outcome of these experiments will significantly influence the direction of dark matter research.

There were proposals that dark matter might be ultra-light scalar particles in Bose-Einstein condensation phase, but the idea doesn't seem to have caught on. What are the advantages / disadvantages of this model?
 
Astronomy news on Phys.org
The currently most popular dark matter models assume its some type of WIMP, i.e. a particle that interacts on the same scale as weak interactions. If this is so, we are getting very close to detecting it.

Especially the Xenon100 experiment should soon have enough sensitivity to either detect or rule out WIMPS. If they fail to see it, you can be sure the whole idea of dark matter will be rehashed, and other theories like the one you mention will attract more interest.

What do you mean by "soon"? Couple of months?
Also, I hear Xenon 1t is planned as a more powerful probe, so Xenon100 shouldn't be the end of the story for WIMPs?
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
