You can have lots of heat, even more heat, super-heat, mega-heat, unlimited heat, white heat, a little heat or no heat, but we don't have anything called 'cold'. We can hit down to 458 degrees below zero, which is no heat, but we can't go any further after that. There is no such thing as cold; otherwise we would be able to go colder than the lowest -458 degrees. Every body or object is susceptible to study when it has or transmits energy, and heat is what makes a body or matter have or transmit energy.. Absolute zero (-458 F) is the total absence of heat. Cold is only a word we use to describe the absence of heat. We cannot measure cold. Heat we can measure in thermal units because heat is energy. Cold is not the opposite of heat, just the absence of it.'
Same with darkness!
Darkness is not something; it is the absence of something. You can have low light, normal light, bright light, flashing light, but if you have no light constantly you have nothing and it's called darkness? That's the meaning we use to define the word. In reality, darkness isn't. If it were, we would be able to make darkness darker.'
Compliments go to Einstein and a discussion had between himself and his Philosophy Professor!
I found that very interesting!
