Is darkness a form of light?
To answer your question, we have to start with a solid definition of darkness.
I like “darkness is the absence of light.” Using that definition, then the answer has to be “no, because dark objects do not emit visible light.” …
But all light is electromagnetic energy, which is made of photons..
Where does energy go after you die?
We can gain energy (again, through chemical processes), and we can lose it (by expelling waste or emitting heat). In death, the collection of atoms of which you are composed (a universe within the universe) are repurposed. Those atoms and that energy, which originated during the Big Bang, will always be around.
Does Matter ever disappear?
This is called the Law of Conservation of Matter. It states that matter can never be created or destroyed, only changed and rearranged. … They may be bonded into different molecules, or in a different state of matter, but they cannot disappear. When changes occur, energy is often transformed.
Can matter be transformed?
Matter can be transformed by application of heat or cold, by oxidizing/reducing chemistry, by EM radiation including light, acoustic radiation or by nuclear reaction (fission or fusion).
What happens when matter is destroyed?
However, matter is destroyed when a particle meets its antiparticle, e.g., a positron meets an electron. In this case, two photons are given off. … So the answer is matter can be destroyed, it is being destroyed all the time, and what happens is that light is created.
Can matter be destroyed in a nuclear reaction?
The total mass of the matter remains a constant in any chemical change. The total mass of the matter can change during a nuclear reaction, the mass loss can convert into energy, which is called the nuclear power. So we can say that a nuclear reaction creates/destroys matter, if we define matter only as its mass.
Does light go on forever?
Light is a self-perpetuating electromagnetic wave; the strength of the wave can get weaker with the distance it travels, but as long as nothing absorbs it, it will keep on propagating forever.
Can light be destroyed?
Light is a form of energy. Energy can neither be created, nor destroyed. It can only be changed from one form to another form. … No you can’t destroy light, because light is a form of energy so you can change the light energy into another form.
Can an atom be destroyed?
Atoms cannot be created nor destroyed, and they are indestructible; they cannot be broken into smaller parts. This was based on the Law of Conservation of Mass. It was later learned that atoms can break into smaller parts. … Atoms of different elements have different mass and properties.
Can mass be destroyed?
The law implies that mass can neither be created nor destroyed, although it may be rearranged in space, or the entities associated with it may be changed in form. For example, in chemical reactions, the mass of the chemical components before the reaction is equal to the mass of the components after the reaction.
What does E mc2 mean?
It’s the world’s most famous equation, but what does it really mean? “Energy equals mass times the speed of light squared.” On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
Does Purepower exist?
So the full answer to the question of whether pure energy exists is: For all of the particles that exist, massive and massless, energy is only one property of them, and cannot exist independently.
Can matter be created or 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.
Can humans create matter?
To manufacture matter in a way that adheres to the first law of thermodynamics, you have to convert energy into matter. … So yes, humans can manufacture matter. We can turn light into subatomic particles, but even the best scientists can’t create something out of nothing.
Why does light travel so fast?
According to Einstein’s general theory of relativity, as an object moves faster, its mass increases, while its length contracts. At the speed of light, such an object has an infinite mass, while its length is 0 — an impossibility. Thus, no object can reach the speed of light, the theory goes.
