Obviously, we canât directly measure the size of the universe but cosmologists have various models that suggest how big it ought to be. For example, one line of thinking is that if the universe expanded at the speed of light during inflation, then it ought to be 10^23 times bigger than the visible universe.
If you smell burning from your AC unit, you probably have an electrical problem. The burning smell can come from either a blower motor that overheated or a mechanical failure of some sort. This is due to the build up heat of plastic insulation on wires, causing melting and the burning smell in your unit. Also, if plastic, rubber, or other objects get caught in your ductwork, this can cause a burning smell. Even dirty air filters can overheat your AC unit, creating a burning smell.
