In summary, the black hole will warp the device and produce an interference pattern or a particle pattern.

passing a black hole from double slit experiment setup

Hello,

Theoretically any object can convert into black hole by compressing its mass below some radius( describe by Schwarzschild Radius). Suppose one of this object after becoming black hole have radius
which is comparable to atoms and nucleus radius. Now my question is what will happen if we pass this object into double slit experiment setup (single black hole at a time). Shall we get interference pattern on detector wall because of its radius in quantum domain ( say we somehow know when on detector screen this black hole will hit) or simple particle like pattern (i.e. classical way ) because of mass associated with that black hole?Please understand hole in place of kole in thread title

The object size is the same as the slit; the tidal forces will rip the device apart!

Your question should be: if you have a really tiny black hole, will it be a classical particle, or will it exhibit quantum behavior?

For the "minimum sized black hole": http://en.wikipedia.org/wiki/Micro_black_hole#Minimum_mass_of_a_black_hole
So by this reasoning the minimum size would have a mass of 22 micrograms; you can calculate its radius.

You should also consider Hawking radiation, a quantum effect:

So how long will your micro-black hole exist? Will it have time to make it from production to the recording device?

You now have lots of formulas to evaluate!

Since you are proposing atomic scales, why not take a definite case: a common salt crystal. You can look up the spacing, and you can find the dissociation energy here:

There is no such thing as quantum domain. ALL scales are quantum in nature, ALL objects are quantum in nature, ALL of physics is quantum in nature.

Is this a helpful comment? There are many effects which can be fully explained via classical reasoning - Newton's Laws of Motion still hold for objects like your shoes and socks!

Sure, I know that you, personally, have a de Broglie wavelength - when you are moving - but is it measurable? Do we see diffraction when you run through a double door? I don't think so.

Hence my reframing of the question.

I think my comment is very helpful. The OP thinks Quantum Mechanics stops working outside some kind of domain. That's incorrect and I pointed that out. If the question was about the domain of Classical Mechanics it would be OK since Classical Mechanics indeed stops working outside of its domain of application. It's not proper to think of Classical Mechanics as being outside of the domain of Quantum Mechanics. Classical Mechanics can be derived from Quantum Mechanics, but Quantum Mechanics cannot be derived from Classical Mechanics.

From schwarzschild radius I've found that radius for 22 micrograms black hole is 32.60 * 10^ -36 meter and time to evaporate is 864.2924*10 ^ -25 second. So I think time is very small to evaporate the whole black hole, But again my question is that if we take "ideal" condition that somehow this black hole reaches to detector wall can we get interference pattern or particle pattern?

The "ideal" situation here will not prevent this black hole from warping both your "slit" and your detector!

This thread has become too highly speculative.

## 1. What is the double slit experiment setup and what is a black kole?

The double slit experiment is a famous physics experiment designed to demonstrate the wave-particle duality of light. It involves passing a beam of light through two parallel slits and observing the resulting interference pattern on a screen. A black kole, or colloidal gold, is a suspension of gold particles in water that is used in the experiment to scatter light and create the interference pattern.

## 2. How does passing a black kole from double slit experiment setup change the results?

Passing a black kole through the double slit experiment setup does not change the results significantly. It may slightly alter the intensity of the interference pattern, but the overall pattern and principle of interference remains the same.

## 3. Can different types of particles be used in the double slit experiment setup?

Yes, the double slit experiment has been performed with various types of particles, including electrons, protons, and even large molecules like buckyballs. In each case, the particles behave like waves and create an interference pattern on the screen.

## 4. What does the interference pattern produced by the double slit experiment setup tell us about the nature of light?

The interference pattern demonstrates that light has both wave-like and particle-like properties, known as wave-particle duality. This is a fundamental concept in quantum mechanics and helps us understand the behavior of light and other particles at a subatomic level.

## 5. Are there any real-life applications of the double slit experiment setup?

While the double slit experiment is primarily a demonstration of quantum mechanics principles, it has also been used in real-life applications. For example, electron microscopes use the principles of the double slit experiment to produce images with higher resolution than traditional microscopes. The principles of interference are also used in technologies such as holography and diffraction gratings.
