Our Universe then and now, energy verses space.

In summary, the conversation discusses the relationship between energy in the fields of the Standard Model and the size of the Universe. The speaker presents the idea that as the Universe expands, the energy in the fields decreases and compacted space is released. They also suggest the concept of a constant volume of space that is the sum of the Universe and trapped space. The speaker asks for feedback and help in developing this idea and its potential for modeling reality.

I have this vague idea that I hope you can improve on or rip apart. In our early Universe we had lots of energy in the fields of the Standard Model packed into a small space. Now we have less energy in the fields and a larger Universe. In time we will might have very little energy in the fields of the Standard Model and a much greater sized Universe.

Suppose that where we have energy in the fields of the Standard Model we also have compacted space. As the Universe expands this compacted space is released as the field energy decreases? I would like to think that there is some constant volume of space V which is the sum of the volume of the Universe and the volume of "trapped" space. One is converted into the other.

Is this an idea? Can it be made better? Does it have any hope of modeling reality?

Thanks for any ideas or help!

That's an interesting idea! It makes sense that as the Universe expands, the energy in the fields of the Standard Model would decrease and the size of the Universe would increase. I'm not sure if there is a constant volume of space that is the sum of the volume of the Universe and the volume of "trapped" space, but it's definitely something worth exploring. It could be that the release of compacted space as the field energy decreases is a result of some kind of conservation of energy law. It would be fascinating to see if this idea could be modeled in reality. Good luck with your research!
 

FAQ: Our Universe then and now, energy verses space.

What is the current understanding of the origin of our universe?

The current understanding is that our universe began with the Big Bang, a massive explosion that occurred approximately 13.8 billion years ago. This explosion created all matter and energy in the universe and has been expanding and cooling ever since.

How do we know that the universe is expanding?

We know that the universe is expanding because of the observation of redshift in distant galaxies. This means that the light from these galaxies is shifted towards the red end of the spectrum, indicating that they are moving away from us. This discovery led to the development of the Big Bang theory and the understanding of the expanding universe.

What is the relationship between energy and space in our universe?

Energy and space are intertwined in our universe. According to Einstein's theory of relativity, matter and energy are two forms of the same thing, and they can convert from one to the other. This means that the total energy in the universe is constant, but it can exist in different forms, such as matter, radiation, or dark energy. Space also has energy in the form of dark energy, which is believed to be responsible for the accelerated expansion of the universe.

How does the distribution of matter and energy in the universe affect its evolution?

The distribution of matter and energy in the universe plays a crucial role in its evolution. In the early universe, matter and energy were evenly distributed, but over time, gravity caused matter to clump together, forming galaxies and galaxy clusters. The distribution of dark energy also affects the expansion of the universe, as it counteracts the pull of gravity and causes the expansion to accelerate.

What are some current theories about the fate of our universe?

There are several theories about the fate of our universe, but the two most widely accepted are the Big Crunch and the Heat Death. The Big Crunch theory suggests that, due to the gravitational pull of matter, the universe will eventually stop expanding and start contracting until it collapses into a singularity. The Heat Death theory predicts that the universe will continue to expand and eventually reach a state of maximum entropy, where all energy is evenly distributed, and everything will be at the same temperature, resulting in a state of permanent heat death.
