It may
There was no outside. Space itself has expanded together with the matter it contained.
Ear wax "flows" from the inside to the outside carrying dirt and other particulate matter out of the ear.
What does the quote "The essence of a business if outside itself"
No, sound travels through matter but is not matter itself.
No.Properties are descriptions of matter, but not matter itself.
Not by itself, it requires an ignition source.
Because the star that blew it off of itself was rotating. Conservation of rotational momentum.
The light itself is the same as any light and is not matter.
Chemical change
The law of conservation of momentum states that the total momentum of a closed system remains constant if no external forces are acting on it. Momentum itself is the product of an object's mass and velocity. Therefore, the relationship between momentum and the law of conservation of momentum is that the total momentum of a system before a collision or interaction must be equal to the total momentum after the collision or interaction.
Matter, by itself, is not sentient. So matter is not capable of any kind of consideration. So it cannot consider anything to be, or not to be, matter.
The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. However, Einstein's theory of relativity introduced the concept of mass-energy equivalence (E=mc^2), which asserts that mass and energy are interchangeable. This means that in certain situations, mass can be converted into energy and vice versa, challenging the classical notion of energy conservation.
