What is the smallest measurable length and amount of time that can be achieved with todays technology ?
micromass said:What do you mean with "achieved"?? Do you mean: the smallest length that we can observe with a microscope? The smallest length that we can measure? The smallest length of something we can construct??
The smallest measurable length is the Planck length, which is approximately 1.6 x 10^-35 meters.
The smallest unit of time is the Planck time, which is approximately 5.4 x 10^-44 seconds.
The Planck length and time were determined by German physicist Max Planck in 1899, who used fundamental constants such as the speed of light, gravitational constant, and Planck's constant to derive these values.
The Planck length and time are important because they represent the smallest possible measurements in the known universe and are believed to be the limits of our current understanding of physics. They also play a role in theories such as quantum gravity and string theory.
It is currently believed that the Planck length and time are the smallest possible measurements. However, as our understanding of physics evolves, it is possible that these values may change or be surpassed by even smaller units of measurement in the future.
