Did energy begin to exist? Can energy exist without space and time?

In summary, the concept of energy and its existence at the Big Bang and without space and time is a complex and debated topic in science and physics. The definition of energy and its relationship to time and space must be better understood before the question can be answered.

Did energy begin to exist at the Big Bang? Can energy exist without space and time?

Or don't we know?

When I've tried to research this I get a mix of different answers. I have virtually no understanding of science or physics in general FYI.

Well, first you have to define what you mean by energy.

You can start with the basics. It is not a thing. It is a number.

The notion of something "beginning to exist" before time exists is something of an oxymoron. You'll have to put your question on much firmer footing before it can be answered.

The Big Bang was not the start of the universe. Whatever a "start" is is not even defined. It would be a discontinuity of time.
 

1. Did energy truly begin to exist?

There is currently no scientific evidence to suggest that energy had a beginning. The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. Therefore, it is likely that energy has always existed in some form.

2. Can energy be created without space and time?

It is difficult to answer this question definitively because the concept of energy is closely tied to the concept of space and time. However, some theories, such as quantum mechanics, suggest that energy can exist in a vacuum or in a state of "nothingness". This is a complex and ongoing topic of research in the field of physics.

3. Can energy exist without matter?

Yes, energy can exist without matter. In fact, energy is a fundamental component of matter and is constantly being exchanged between particles. However, matter is not a necessary component for energy to exist. For example, light is a form of energy that does not require matter to propagate.

4. How is energy related to space and time?

Energy and space-time are closely interconnected. Space and time are dimensions through which energy can move and interact. Energy can also affect the fabric of space and time, as seen in Einstein's theory of general relativity. Without the framework of space and time, the concept of energy would not have the same meaning.

5. Can energy be destroyed?

No, energy cannot be destroyed. As mentioned earlier, the law of conservation of energy states that energy cannot be created or destroyed, only transformed. This means that while energy can change forms, the total amount of energy in a closed system will remain constant. This principle is fundamental to our understanding of the universe and has been extensively tested and confirmed through experiments.
