Could anti-mass explain the missing anti-matter from the big bang?

In summary, the rubber-sheet model of gravity suggests that the mass of an object creates hollows in space-time, while anti-mass would create bumps. This would result in a foam-like structure with voids and a network of matter, similar to the cosmic web. However, there is no evidence for the existence of anti-mass, as observed in the Tevatron experiments. This may explain the imbalance of matter and anti-matter in the universe.

The rubber-sheet model of gravity pictures gravity as the effect of hollows in space-time due to the mass of an object. If the model included bumps in space-time as well, the effect would be to channel all the mass into the valleys between the bumps forming a network of matter across the sheet. Turning the flat sheet into three dimensions, with space-time in the fourth, we would end up with a foam-like structure of voids surrounded by a 3-D network of matter, very much like the cosmic web. What could cause such bumps in space-time? If mass causes the hollows anti-mass would cause bumps, but can such a concept as anti-mass exist? If it did it might help explain the missing anti-mater from the big bang.

Antimatter does not have negative mass. It has positive mass and attracts things just like normal matter. The Tevatron has been colliding protons with antiprotons since it was built in 1983. When an E field is applied, the antiprotons accelerate in the normal way expected for a particle having mass equal to a proton and a negative charge. They circulate in the machine for hours at a time, and have never been observed to "fall up"!
 

1. What is inflation in the context of the cosmic web?

Inflation is a theory in cosmology that suggests the universe underwent a rapid expansion during its early stages, causing it to become much larger and smoother than it was originally. This rapid expansion is thought to have smoothed out any irregularities in the distribution of matter, leading to the formation of the cosmic web.

2. How does inflation explain the formation of the cosmic web?

Inflation is thought to have stretched out any small variations in the density of matter in the early universe, leading to a more uniform distribution. As the universe continued to expand and cool, gravity caused this denser regions of matter to clump together, eventually forming the large-scale structure of the cosmic web.

3. What evidence supports the theory of inflation?

One of the main pieces of evidence for inflation is the observed uniformity of the cosmic microwave background radiation, which is considered a remnant of the early universe. This uniformity is difficult to explain without the rapid expansion of inflation. Additionally, observations of the large-scale structure of the universe, such as the distribution of galaxies, also support the theory of inflation.

4. Are there any alternative theories to explain the formation of the cosmic web?

Yes, there are alternative theories to explain the formation of the cosmic web, such as the top-down theory and the bottom-up theory. The top-down theory suggests that the largest structures in the universe formed first, while the bottom-up theory proposes that smaller structures formed first and then merged together to form larger structures. However, both of these theories have been largely discredited in favor of the inflation theory.

5. How does the cosmic web affect the development of galaxies and other celestial bodies?

The cosmic web acts as a framework for the formation and evolution of galaxies and other celestial bodies. The densest regions of the cosmic web, known as filaments, provide the necessary gravitational pull for gas and dust to clump together and eventually form galaxies. The cosmic web also influences the movement and interactions of galaxies, leading to the diverse structures and shapes we observe in the universe.
