Who said nothing can be created or destroyed?
“Energy cannot be created or destroyed; it can only be changed from one form to another.” (Albert Einstein).
What did Albert Einstein said about death?
“Our death is not an end if we can live on in our children and the younger generation. For they are us; our bodies are only wilted leaves on the tree of life.”
What did Einstein mean when he said energy Cannot be created or destroyed?
The law of conservation of energy states that energy can neither be created nor destroyed – only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it’s added from the outside.
How does matter exist if it Cannot be created?
Matter is continuously destroyed in stellar interiors which are undergoing nucleosynthesis (sort of like continual hydrogen bombs). In that process some matter is converted into radiation, energetic photons and neutrinos. Matter is also destroyed entirely within black holes, as far as we know.
Can neither be created or destroyed?
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.
Can matter be destroyed?
Matter makes up all visible objects in the universe, and it can be neither created nor destroyed.
Is it true that matter can neither be created nor destroyed?
Matter is anything that has mass and takes up space. Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
How can energy be created and destroyed?
As we know through thermodynamics, energy cannot be created nor destroyed. It simply changes states. The total amount of energy in an isolated system does not, cannot, change. And thanks to Einstein, we also know that matter and energy are two rungs on the same ladder. The universe as a whole is closed.
Is Energy conserved in the universe?
Energy was conserved. Modern cosmology has offered up new riddles in energy conservation. We now know that the universe is expanding at a faster and faster rate—propelled by something scientists call dark energy. This is thought to be the intrinsic energy per cubic centimeter of empty space.
Why don’t we die instantly when a nerve ignites?
The point is, there are mechanisms that maintain an imbalance of charge (which is electricity waiting to happen), and that imbalance is drained a little bit every time the nerve fires. Death (excluding spectacular deaths) isn’t instantaneous.
How would you define death?
Time was you could define death as being a lack of heart beat, but people have come back from worse (by that metric, Dick Cheney has been dead for a while ). Death is more of a break-down of the whole system, as opposed to a sudden event.
