I Create black hole with lasers? Physics project

  1. Nov 2, 2016 #1

    We have a projekt at the university and I have been thinking of creating a tiny tiny black hole after I've read some articles. I know one can create an artificial black hole with polarized laser pulses at a block of glass. And then one can measure a lot of things, usually hawkingradiation (in some certain way). BUT, do someone know how to making this experimental setup practically? Which lasers, what glass, what detectors and what eventual program to use? Someone with experience? We have access to a lot of laboratories and a budget if we need to order something.

    Here is some articles that describe it very briefly, but know how to do it practically unfortunately.

    1) http://www.sciencemag.org/news/2010/11/physicists-create-black-hole-light-lab
    2) https://www.newscientist.com/article/dn22347-black-hole-laser-edges-closer-to-testing-hawking/

    Thankful for some input if it is possible to do the experiment in some way.

    Event horizons of astrophysical black holes and gravitational analogues have been predicted to excite the quantum vacuum and give rise to the emission of quanta, known as Hawking radiation. We experimentally create such a gravitational analogue using ultrashort laser pulse filaments and our measurements demonstrate a spontaneous emission of photons that confirms theoretical predictions.

    First, this is not creating a black hole, but a black hole analogue, something that has some properties similar to a black hole, but is not a space-time singularity.

    Second, if you have to ask "which laser", then you do not have the expertise to build such an experimental setup. The knowledge of lasers and optics needed to make such an experiment is huge.

    Neither sciencemag.org nor newscientist.com are acceptable sources here; they are not peer-reviewed and often misrepresent the research they're reporting on.

    In this case, they may not be actively misrepresenting anything, but you do have to read the articles more carefully than you have to see that they are NOT saying that anyone has created an artificial black hole.

    If you want to understand any new development in any depth, you have to skip over sciencemag.org, newscientist.com, and the like, and go straight to the real thing - in this case the paper that mentz114 linked to. Be aware that even when the paper is behind a paywall, you can often find a preprint at arxiv.org; that's what mentz114 did for you this time.

    For sciencemag.org that applies to the "News" section. The "Journals" section is peer-reviewed. However, I think sciencemag's news section is better (more reliable) than newscientist.
