Gravity's Effect on Universe Expansion: Dark Energy?

In summary, the conversation discusses the potential effects of gravity on subspace and the expansion of the universe. The possibility of an undetectable energy source and negative pressure in subspace leading to the expansion of atoms in normal space is raised, along with the idea that the universe's accelerating expansion could be caused by varying levels of gravity forces. The concept of dark energy is also mentioned. However, the question itself is deemed nonsensical as "subspace" is not a valid term in physics.

Does gravity create a wake in subspace? If so would this wake produce a undetectable energy source or negative pressure in subspace which would indirectly lead to the expansion of all atoms in normal space that sit upon it?

If the universe's expansion is accelerating then could this be because after the initial big bang (a few million-billion years later) there were more distorting gravity forces (stars, black holes, etc...) which would produce more of the wake effect then less distorting gravity forces (gas clouds) which would have existed earlier?

Could this be dark energy?

You may think that this post is hilarious, as I know little of physics, but I thought I'd throw it out there and see if its complete garbage.

I'm sorry but your question doesn't make any sense. "Subspace" may be a term tossed around in science fiction, but this does not equate to real physics.

Thank you for sharing your thoughts on the relationship between gravity and the expansion of the universe. While your ideas are certainly interesting, they are not supported by current scientific understanding.

Firstly, it is important to clarify that gravity itself is not responsible for the expansion of the universe. In fact, gravity acts as a force of attraction that would normally slow down the expansion. It is actually the presence of a mysterious force called dark energy that is causing the universe's expansion to accelerate.

Dark energy is a hypothetical form of energy that is thought to make up about 70% of the total energy in the universe. Its existence is inferred by the observation that the expansion of the universe is accelerating, and it is believed to be a property of space itself rather than a physical object. Therefore, it is not creating a wake in subspace or producing any kind of energy source or negative pressure.

Furthermore, the expansion of the universe is not caused by individual atoms being pushed apart. Instead, it is the space between galaxies that is expanding, carrying the galaxies along with it. This expansion is happening on a large scale and is not affected by the presence of individual objects like stars or black holes.

In summary, while your ideas are creative, they do not align with current scientific understanding of gravity, dark energy, and the expansion of the universe. It is always great to see people engaging in scientific thinking and asking questions, but it is important to seek out accurate information and evidence-based explanations.
 

Related to Gravity's Effect on Universe Expansion: Dark Energy?

1. What is dark energy?

Dark energy is a theoretical form of energy that is believed to be responsible for the accelerating expansion of the universe. It is thought to make up about 70% of the total energy in the universe.

2. How does dark energy affect the expansion of the universe?

Dark energy is thought to be causing the expansion of the universe to accelerate, counteracting the gravitational effects of matter and causing the universe to expand at an increasingly faster rate.

3. Is dark energy related to gravity?

Dark energy and gravity are both components of the theory of general relativity, but they have opposite effects on the expansion of the universe. While gravity pulls matter together, dark energy pushes it apart.

4. How is dark energy measured?

Dark energy cannot be directly observed or measured, but its effects can be seen through its influence on the expansion of the universe. Scientists use measurements of the expansion rate and density of the universe to estimate the amount of dark energy present.

5. What is the relationship between dark energy and the fate of the universe?

The amount of dark energy in the universe will determine the ultimate fate of the universe. If dark energy continues to accelerate the expansion of the universe, it will eventually lead to a "Big Freeze" where the universe will continue to expand and cool until all matter and energy are spread out and the universe becomes a cold, dark place.
