Comment Hardly noteworthy speculation (Score 2) 120

As noted or hinted upon by others, the concepts challenged in this paper (i.e. general relativity) are very well established and tested experimentally, e.g., in the context of GPS. Conversely, the question of what negative masses or mass densities would imply is obvious, so that probably every single physics student or professor has thought about it. Still, nobody seems to have found any traces of negative masses.

Thus, the authors suggestions should be viewed as (potentially) somewhat interesting speculation or an empirical approach for fitting cosmological data.

I dont think there is anything new that the general public could/should learn from this news or the article.

Comment This is a revolution (Score 1) 56

The implementation of the powers of ChaptGPT and assoicated technologies into the Microsoft office suite will be a complete game changer. Nobody (in his right mind) will manually organize emails when an AI can perfectly sort emails, alert you of important infos and deadlines and suggest answers or actions.

This has no more similarity to Clippy than a Tesla has to a toy car.

Comment Effectively 100% gas - electricity conversion (Score 3, Insightful) 327

You failed to consider that the target applicants are already using gas for heating purposes anyway. Now the heat production of the engine will be exactly matched to this need (same as before). All extra gas consumption is fully transformed into electricity (which is possible, even for only 40% raw conversion efficency, as long as the electrical output is much below the heat load).

So, overall, the extra gas consumption (compared to conventional heating) is transformed with 100% efficiency into electricity which is a vast improvement over all competing technologies with similar flexibility.

Comment Integration with NASA ADS (Score 1) 211

No, I (theoretical solid state physicist) didn't know about NASA ADS, but it seems to cover most of the relevant literature (including arXiv and APS journals). So yes, an integration into I, Librarian would be great.

In CERN DS (with certainly a focus on high-energy physics) my papers are shown only up to 2006; so this database appears useless for me.

Comment I, Librarian seems pretty close (Score 1) 211

What the submitter needs (and I also need) is an organizer for scientific papers with an interface for standard fields such as authors, journal, title, doi, http links etc. I, Librarian seems to fulfill this need; unfortunately with direct interfaces (for retrieving pdf and meta information at the same time) only with pubmed.

If anybody knew of (or planned for) an adaptation to physics (with interfaces to arXiv.org, the APS journals and ideally other journals), I would be very interested (even as a paying customer).
