E=mc2 Energy is matter in motion. They are essentially interchangeable. Matter rises from energy. Matter has energy and can be turned back into energy. We could say matter and energy are different values of the same thing.
You can see the world as matter with energy as the ability to do work, influence matter. Or you can see the world as energy, with portions in states of matter. Just consider how a particle can be seen as a particle (matter) or a wave form (energy). Science studies the world from various perspectives all the time.
But energy cannot be created or destroyed. Energy can be controlled and directed. Working with energy is much more powerful and effective than working with matter.
The Big Bang was energy, from which matter was formed. Stars are energy furnaces that form the elements. Energy forms matter.
As for what caused the Big bang, what happens after death, is there a Creator - these are not questions science can answer as they are beyond the field of energy and matter. To answer those questions, you have to study the container of energy and matter. Ask people who study that level of existence. And there are answers, beyond philosophic opinions. But they require their own type of science and research, beyond mind. | I wrote to Fred Alan Wolf (Dr Quantum on what the bleep) on the subject of E=mc2. This was his reply. Quote:
Both time and space are non-constructible concepts. Certainly
E=mc² says something about both space and time in that it implies that
space and time form a continuum which means that what would be a spatial
extent for one observer, could be seen to be a temporal and spatial interval
for another.
In quantum physics we relate space and time to energy and
momentum in the sense that something that doesn’t change as time goes on
reflects a constant energy and something that doesn’t change as one moves
through space reflects a constant momentum.
In quantum physics energy is also related to frequency so something with a high mass would have a high frequency. When we look into the scale of things that happen we find that events occur naturally on a scale where the speed of light is one unit and Planck’s constant is also one unit. In this case both time and space scale as one divided by mass. Hence very small masses range over large distances and time intervals and large masses over smaller distances and time intervals. Writing ħ as Planck’s constant and c as the speed of light we have the space scale as ħ/mc and time scale as ħ/mc². If
something has zero mass, then both scales are infinite, hence light, which
has zero mass moves across the universe while electrons are confined to
atomic distances and quarks are confined to nuclear distances.
Oh, all concepts in physics are constructed so that we can agree on
what we mean by numerical measures. Hence what we mean by space and time is determined by how we agree to measure such intervals. I hope this
helps.
