Conversely, the largest (in terms of mass) fundamental particle we know of is a particle called a top quark, measuring a whopping 172.5 billion electron volts, according to Lincoln. Lincoln said there are two ways to measure the size of particles: investigating their mass and measuring their physical size, like calculating the diameter of a ball. They can wear a helmet, bright clothing, and put flashers on the bike. Trevor Makal, a professor at the University of Virginia, took to Twitter to share his take on the question - and it all comes down to the size of the molecules that make up both the smell in a fart and the coronavirus, and how they pass through materials. Currently, the smallest physical size scientists can measure with a particle accelerator is 2,000 times smaller than a proton, or 5 x 10^-20 m.
