And your answer didn’t make sense at first because I thought “how would a piece of equipment that is used to listen to the heart be involved in this?”
Then i looked it up :)
Only 52 and sometimes those mistakes worry me.
That sounds like a real unsolvable problem!
Quite true. The best physicists earn their livelihood by trying to figure out answers to such questions. And quantum entanglement is the biggest unknown on their plate because it speaks to the very fabric of reality.
Matter cannot be destroyed? That’s false.
Matter is not conserved. What is conserved is mass.
Take the sun. As hydrogen burns to form helium, the mass of the matter decreases. The sun radiates away infra red, visible light, x-rays, etc. They have mass. The total of the mass of the matter, and the mass of the radiation stays the same.
Take an atomic reactor. As the fuel burns, the mass of the fuel is decreasing (at a rate equal to the square of the speed of light, or 19.7 trillion Btu’s per pound in US Standard units.) In a typical 1100 mw reactor, the mass of the fuel drops by about 5 pounds a year.
But mass is always conserved. So where does the mass go?
In water cooled reactors, it goes into the reactor coolant water.
When you add energy to something (heating water, lifting a weight, tightening a spring, charging a battery), its mass goes up. So as the water circulates through the reactor and it heats up from about 570 to 630 deg F, its mass goes up. When it loses its heat by boiling off steam in the boilers, the mass of the cooling water goes back down again, The mass of the steam goes up when boiling occurs, so mass is always conserved.
DANGER!
Warning!
This stuff can make your brain hurt.

Painfully, I now sometimes make spelling and grammar mistakes that I never made during my long ago school days.
