By definition the space time fabric must have mass.

In summary, the conversation discusses the unexpected expansion of the universe and questions whether the creation of space time during the big bang could have resulted in a wave that pulls matter and energy further from its source. The idea of "space time mass" is also considered and the conversation ends with a request for thoughts on the topic.

Hello all,

My post involves the unexpected continued expansion of the universe. As if matter is being accelerated by some means of unknown repulsion.

Let us assume that current space time theory is correct. And that there is a "fabric" of space.
We are all familiar with the grid representation of space time with a gravity source acting as a dimple.

Now let us consider the big bang. All matter and energy is condensed in a practically infinite
singularity. So, at this point even space time does not exist outside of this singularity.

Now, in one instant this singularity erupts all space time matter and energy into the universe.
This means that the actual "fabric" of space time is also created. Would not this space time
creation result in a wave of creation. A wave that would force matter from its source and continue to propagate.
Hence, as the space time fabric is created it would actually pull matter and energy further from source.

So, instead of dark matter, it is the "mass" of the immense expanse of space time that should fill these equations.
Looking at it a different way, if space time is warped by gravity, then it must have mass.

Your thoughts?

How would you define the mass of "space time"

What is the space time fabric?

The space time fabric is a concept in physics that describes the fabric of the universe. It is a four-dimensional continuum that combines space and time into a single entity.

What is meant by "by definition the space time fabric must have mass"?

This statement means that according to the theory of general relativity, the space time fabric is not a completely empty void, but rather has a physical property of mass. This mass is what creates the gravitational force that affects the motion of objects in the fabric.

How is the mass of the space time fabric measured?

The mass of the space time fabric is not directly measured, as it is a theoretical concept. However, its effects on the motion of objects, particularly through the force of gravity, can be observed and measured.

What implications does the concept of the space time fabric having mass have on our understanding of the universe?

This concept has significant implications on our understanding of the universe, particularly in regards to gravity and the motion of objects. It also helps to explain phenomena such as the bending of light and the presence of black holes.

Is there any evidence to support the idea of the space time fabric having mass?

While there is not direct evidence of the space time fabric having mass, the theory of general relativity and its predictions have been extensively tested and confirmed through various experiments and observations. This lends support to the idea of the space time fabric having mass.
