| dc.description.abstract | We demonstrate how one can extract the Planck length from a ball with a built-in stopwatch, without knowledge of the Newtonian gravitational constant or the Planck constant. This could be of great importance since, until recently, it has been assumed the Planck length cannot be found without knowledge of Newton’s gravitational constant. This method of measuring the Planck length should also be of great interest not only to physics researchers but also to physics teachers and students, as it conveniently demonstrates that the Plank length is directly linked to gravitational phenomena, not only theoretically but practically. To demonstrate that this is more than a theory, we report 100 measurements of the Planck length using this simple approach. We will claim that, despite the mathematical and experimental simplicity, our findings could be of great importance in better understanding the Planck scale and quantum gravity, as our findings strongly support the idea that to detect gravity is to detect the effects from the Planck scale indirectly. | |
