What if elementary particles do have size

In summary, the conversation discusses the possibility of seeing the structure of electrons by zooming in with a microscope. However, it is not possible to see an object or structure of an electron due to the limitations of resolution in viewing particles. Modern theory suggests that particles are field excitations and do not have a classical structure. This is why particle accelerators are used to study particles.

Is it possible that they have the structure something like we used to picture them as? For example, what if we captured an electron and zoom in with a microscope that see infinitly small distances. Is it possible that if we zoomed into the electron close enough that we would see an object? Maybe something like a ball or something? And if no why not

Such a thing does not exist. One can view particle accelerators as an attempt to create such a thing, but they have limits to their resolution too.

seeing an electron is tantamount to bouncing a photon off of it. individual photons don't really have great resolutions to "see" anything. if you want to see the structure of particles, you collide them in super-colliders like the LHC. modern theory tells us that particles are nothing but field excitations, so we don't expect it to have "structure" in the classical sense.
 

Related to What if elementary particles do have size

1. What are elementary particles?

Elementary particles are the fundamental building blocks of matter and energy in the universe. They are the smallest possible units of matter and cannot be broken down into smaller components.

2. Do elementary particles have size?

Based on our current understanding of physics, elementary particles are considered to be point-like, meaning they have no physical size or volume. However, some theories suggest that they may have a very small size or structure that we are unable to measure with our current technology.

3. How do we know if elementary particles have size?

Scientists use a wide range of experiments and observations to study the properties of elementary particles. These include particle accelerators, detectors, and mathematical models. So far, the evidence suggests that elementary particles are indeed point-like.

4. What would be the implications if elementary particles do have size?

If elementary particles were found to have size, it would challenge our current understanding of particle physics and the Standard Model. It could also lead to new discoveries and theories about the nature of matter and energy in the universe.

5. Can we ever know for sure if elementary particles have size?

As technology and scientific knowledge continue to advance, it is possible that we may one day be able to directly observe the size of elementary particles. However, for now, it remains a topic of ongoing research and speculation in the scientific community.
