For Heraclitus "PYR" or "fire" represented the primal element of the eternal and uncreated, ever changing, "ever-living" Cosmos. "All things are an interchange for fire, and fire for all things." This can be seen as his anticipation of the concept of plasma, as used in the plasma cosmology of Alfven, Peratt, and others.

Ancient Greek philosopher Heraclitus contended that the primal element of the universe was fire because he believed that everything is in a state of constant change. He coined the phrase "you cannot step into the same river twice" to illustrate this concept.

Is melting a phyical or chemical change?
Melting is a physical change because it involves a change in state from solid to liquid without altering the fundamental chemical composition of the substance.
What happens if you change the number of protons of an element?
The element transforms itself into another element because each element have a specific number of protons. If the number of protons changes, the element changes as well. The number of protons in an atom defines it elemental identity, so if the number of protons in an element increases by one it becomes another element.

Why doesnt the number of protons change for a single element while the neutrons and electrons can?
The protons don't change because if the number of protons changes, the type of element the atom is changes. The number of protons determine the species of the atom.
Is an element a physical or chemical change is it homogeneous or heterogeneous?
An element is a pure substance that is the simplest form of matter and cannot be broken down into simpler substances by chemical means. Therefore, an element is not considered to undergo a physical or chemical change. Additionally, elements are considered homogeneous because they consist of only one type of atom throughout.
Why did alchemists fail to create gold?
Gold is an element. It is impossible to change one element into another by chemical means. It is possible to do so via nuclear reactions, but alchemists did not know about such things.
Are all people living in a parallel universe?
no because in 1 they may be but in others events will change that
Do volume in the universe change?
Yes. The Universe is expanding.
Why is a transmutation calssified as a nuclear reaction?
because that's what it takes to change one element to another, a change to the nucleus.
Why was it important to continue to study the universe?
because nothing is constant in thi world all is said to change.

Did time travel slower in the earliest moments of the Universe compared to how it travels now?
no it didn't because i think they are the same because time did not change
On howrse can you change the element of the fifth element on your horse?
No, you cannot change the element of the fifth element on your horse in Howrse. The element is determined during the horse's creation and cannot be altered afterward.

What theory proposes that the universe does not change with time?
The steady-state universe theory
Why do two isotopes of an element have the same atomic number but differnent mass number?
Because the atomic number is the number of protons in an element. If you change the atomic number you will have a completely different element. The mass number changes because the number of neutrons is different.
