Create black hole with lasers? Physics project

In summary, this experiment creates a gravitational analogue that has some properties similar to a black hole, but is not a space-time singularity. The Hawking radiation emission that is observed confirms theoretical predictions.

Hi!

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.

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Neither sciencemag.org nor newscientist.com are acceptable sources here; they are not peer-reviewed and often misrepresent the research they're reporting on.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

1. How is it possible to create a black hole with lasers?

Creating a black hole with lasers is a theoretical concept that is currently being explored by scientists. It involves using high-energy lasers to concentrate a large amount of energy in a small space, which could potentially create a microscopic black hole. However, this has not yet been achieved and is still a subject of ongoing research.

2. What kind of lasers would be needed to create a black hole?

The type of lasers needed to create a black hole would need to be extremely powerful and precise. They would need to produce a high amount of energy in a short amount of time, and have the ability to focus that energy into a small area. Currently, there are no lasers available that meet these requirements, but advancements in laser technology may make this possible in the future.

3. Is it safe to create a black hole with lasers?

Creating a black hole with lasers is purely a theoretical concept and has not yet been achieved. However, even if it were possible, it would not pose any immediate danger to our planet. The black hole would be microscopic and would evaporate quickly due to Hawking radiation. It would also have a very small mass, so its gravitational pull would be insignificant.

4. What are the potential applications of creating a black hole with lasers?

If scientists were able to create a black hole with lasers, it could have significant implications for our understanding of the universe and the laws of physics. It could also potentially be used for studying the behavior of black holes in a controlled environment, which could lead to new insights and discoveries in astrophysics.

5. Are there any ethical concerns surrounding the creation of a black hole with lasers?

As with any scientific advancement, there may be ethical considerations to take into account when exploring the possibility of creating a black hole with lasers. Some may argue that the potential risks and consequences should be carefully considered before proceeding with such experiments. It is important for scientists to approach this research with caution and prioritize safety and ethical considerations.
