How is light energy different from both sound and heat energy?

Light energy can exist independently of matter. *Studyisland


Does matter really exist?

In our definition of things Matter does exist. It is the 'm' in E=mc². It is common to argue that if the individual constituents of an atom (electrons, protons, neutrons, and other particles) have spatial freedon and are not physically touching each other, then matter is not a real entity. The atomic particles, however, exist because they are bound by fields of magnetic, electric and nuclear energy of such design that gives the atoms their individuality. These same atoms go on to join with other atoms to produce molecules of well defined matter. With energy and mass being interchangeable, the energy component is an important part of the total matter. This question has long ago raised the question of whether matter always existed and if energy (and matter) cannot be created or destroyed, what is the source of it all? The only satisfactory answer is that our universe was designed and assembled outside of the laws of physics that now constitute a part of our universe. Some 'things' are not a part of matter. Therefore, God communicated to us just what He did and why He did it. And then left it to us to discover a whole lot of things about matter.


Does energy only exist in one form?

Energy exists in many different forms. These include kinetic energy, heat, sound, light and other forms of electromagnetism, nuclear energy, chemical potential energy, gravitational potential energy, etc.


Matter tends to exist in its what energy state?

Matter tends to exist in its energy ground state. Both the nucleus and the electron cloud have energy states, representing different levels of excitation. The tendency is to return to ground or lowest state, and when that happens, a photon is emitted with charge representing the energy transition. When the photon comes from the nucleus, it is a gamma ray; when the photon comes from the electron cloud, it is an x-ray.


Does mass and energy take up space?

Mass and energy always have locations in both time and space; the amount of space that they take up depends upon their density, but they do take up some. Since energy is often associated with matter (heat, kinetic energy etc.) it would be the matter that takes up the space. The energy would be in the same space as the matter. But energy can also exist independently of matter (such as a photon of light travelling in space) and in that case, the energy takes up space.

How long does solar energy exist?

Will matter exist even without ideas?

Matter can only 'be'. It's existence is only an idea. For the convenience of analysis, we can think that matter 'exists'. To exist, it needs not an idea but the fourth dimension, that is time. Something that has length, breadth and height can not be said to have existed, if it had not gone through a duration of at least a split-second. So matter can exist without ideas, but can not without duration.

Why can't anything be disconnected from the universe?

The universe is commonly defined as all the time, space, matter, and energy that exist. It does not make sense to ask how something exists outside of what exists. If something exists, it, the space it occupies, and the time it exists in are all a part of the universe by definition.


Is there proof God existed before B.C?

There is no objective proof that God exists, or did exist in the past. However, Christians universally believe that he has always existed and always will.


Does Lord Ganesha exist?

To answer this question we first have to understand and accept the fact that when nothing existed Ganesha was there and he created Bramha Vishnu and Mahesha( Shankar) to build, protect and destroy the universe. He existed before the start and he will continue to exist after the end. Ganesha is an energy which flows in the entire universe. One who worships this energy gets positively charged to attract knowledge, wealth, strength and happiness in his/her life. Limitless love is lord Ganesha and it exists in everyone's heart.
