dark matter
Dark matter
empirical, meaning it can be observed or tested through direct experience or experiment.
Mass is a measurable property of matter, meaning it can be determined using instruments and calculations. It is a measure of the amount of material in an object and can be observed indirectly through its effects on other phenomena, such as its gravitational attraction.
If it could be directly observed then it would not be called dark matter!
If it could be directly observed then it would not be called dark matter!
One detail that supports the idea that matter has observable properties is the fact that matter can have physical characteristics such as color, shape, and texture that can be easily seen or felt. Additionally, matter can exhibit measurable properties such as density, mass, and volume that can be quantified and observed through scientific methods.
Four measurable properties of matter are mass,weight,volume,and pressure.
A continuous flow of negative charges is called an electric current.
Something that is not matter lacks physical substance and mass. This means it does not occupy space or have any measurable weight. Non-material things such as thoughts, emotions, and energy do not share the same properties as matter.
Some measurable characteristics of matter include mass, volume, density, temperature, and specific heat capacity. These properties can be quantified and used to describe and compare different substances.
It is a chemical property. A chemical property is a characteristic of matter that allows it to change to a different type of matter.
Based on just a few simple things that popular news magazines mentionwhen they talk about the weird subject of dark matter, we're pretty safein assuming that dark matter has no electrical charge.-- No place in the universe is known to have dark matter.-- Dark matter is hypothesized ("just a theory") but has never been observed.-- It can't have an electrical charge, because if it did, then---- it would interact with other observed electrical charges and observed electromagnetic fields,------ which is exactly what it doesn't do,-------- which is why it has never been observed and is called "dark" matter.
