Smallest measurable length & amount of time

Click For Summary
SUMMARY

The smallest measurable length currently achievable with today's technology is on the order of the Planck length, approximately 1.616 x 10-35 meters. This length is significant in quantum physics and represents a theoretical limit to measurement. In practical terms, the smallest lengths observable with advanced microscopy techniques, such as electron microscopy, can reach down to atomic scales, around 0.1 nanometers. The discussion emphasizes the distinction between observable lengths and those that can be constructed or measured.

PREREQUISITES
  • Understanding of quantum physics concepts, particularly the Planck length.
  • Familiarity with microscopy techniques, specifically electron microscopy.
  • Basic knowledge of measurement theory in physics.
  • Awareness of the limitations of current measurement technologies.
NEXT STEPS
  • Research the implications of the Planck length in quantum mechanics.
  • Explore advancements in electron microscopy and its measurement capabilities.
  • Study the principles of measurement theory in physics.
  • Investigate the limitations of current technologies in measuring subatomic particles.
USEFUL FOR

Physicists, researchers in quantum mechanics, engineers involved in microscopy technology, and anyone interested in the fundamental limits of measurement in science.

What is the smallest measurable length and amount of time that can be achieved with todays technology ?
 
Physics news on Phys.org
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??
