I noticed...
Previously, when we looked at the atom in our GCSE work we observed the atom and how it was discovered and what it consisted of . We agreed that the Electron, a negatively charged lepton, was the smallest particle as well as recognising that it moved in shells around the nucleus. The nucleus of the atom is extremely dense and makes up the mass of the atom, it is positively charged due to the protons, which are positively charged baryons, and neutrons which have no charge and are also baryons.
I wondered...
However, for Physicians this didn’t quite sit and they needed more knowledge about these little building blocks that are supposedly what compose the universe. After many debates and extensive experiments they found that something must make these protons and neutrons. We found out about Quarks and antiquarks, that matter has is opposing antimatter. Or we even questioned, What is making up the empty space in our universe? Dark matter?
Well, quite frankly get to the point, there must be something much smaller to make up something else. This can be shown in Biology, for example:
Organelles makeup cells, Cells build tissues, these tissues make organs, Organs then lead to organ systems which then make an organisms. This process then carries onto ecosystems and biomes.
I question...
Physics follows a similar concept! So, there are no reasons why we cannot still question if there is smaller, much smaller than what we already know.
