    "It's just an HN convention to have the year in the title when the article isn't the current year. Not only does it not imply badness, it's associated with goodness, since most things from previous years have lost their interest." - dang https://hn.algolia.com/?query=dang%20year%20title&sort=byPopularity&prefix&page=0&dateRange=all&type=comment https://hn.algolia.com/?query=dang%20year%20title&sort=byPop...

      Oh I wasn't aware such a rule existed. Thanks for the heads up. Edited the title.

It's from 2016 if this was the case I am sure it would have made more news. I am no theoretical physicists, but from my understanding we can't figure out how to link/relate gravity to the electromagnetic forces which can be explained quantum mechanically. If you could that would allow for a unified theory of gravity and the quantum world. That would be huge news.

Here's the paper: https://arxiv.org/pdf/1504.00333 https://arxiv.org/pdf/1504.00333

>With Füzfa’s experiment, it may be possible to create artificial gravity in a much smaller space, reducing the cost of spacecraft carrying humans destined for other planets. So, is this claim in any way supported, or even being made by Füzfa? Lets look at the referenced paper. >We finally propose an experimental setup, achievable with current technology of superconducting coils, that produces a phase shift of light of the same order of magnitude than astrophysical signals in ground-based gravitational wave observatories. Hmm, that would seem to suggest making artificial gravity fields that are only as strong on earth as those detected from stars many light years away. How big is the device required? >To conclude this section, we emphasize that the generation and detection of artificial gravitational fields by strong magnetic fields is within experimental reach but requires large multi-layered superconducting magnets powered during dozens of days. How current loops and solenoids curve space-time - https://arxiv.org/abs/1504.00333 https://arxiv.org/abs/1504.00333 Basically, this article is horseshit.

This leads back to the US government analysis of applications of high frequency gravitational waves. Sadly, no hope in sight. www.newscientist.com/article/dn16306-us-investigation-into-gravity-weapons-nonsense/ It's a good 1000 year physics problem.
