In summary, the conversation is discussing the existence of dark matter and its potential interactions with visible matter. The idea is that if there is a sea of undetected dark-matter particles, they could potentially cause vibrations, fission, or fusion of atomic nuclei. However, these effects may be attributed to other causes instead of being recognized as evidence of dark matter. The possibility of dark matter remains hypothetical and its energy spectrum is still unknown.

Return of the Ether?

- There are reasons to believe that the universe contains much unseen dark matter. If it exists, it might be as undetected particles.
- The word "spontaneous" in "spontaneous decay" makes the phenomenon sound as though it were an effect without a cause. There is an accepted cause, of course, but it is of a statistical nature and does not tell us, for example, why one particular atom of Isotope X should have decayed while the immediately neighboring atom of the same Isotope X did not.

Let us assume that there is a sea of undetected dark-matter particles all about us. If a proton or neutron within a nucleus is hit by such a particle, whether directly or not, it should either vibrate or be knocked out of its host nucleus, or the entire nucleus might be caused to fission. There be nothing "spontaneous" about the occurrence. It would simply be a particle-collision event in which one participating particle was not detected.

Diverse details could be attributed to the hypothetical energy spectrum of dark matter.

If this scenario is nonsensical, I would like to know why.

Isn't this self contradictory? If the "undetectable" matter caused vibration and perhaps even fusion of atomic nuclei, wouldn't we notice? Wouldn't that effect be delectable, therefore your dark matter would be detectable.

Yes we do detect, we do notice. But we attribute it to something else.
 

1. What is dark matter?

Dark matter is a hypothetical type of matter that is believed to make up about 85% of the total mass of the universe. It does not interact with light, making it invisible and difficult to detect.

2. How do scientists study dark matter?

Scientists study dark matter through its gravitational effects on visible matter, such as stars and galaxies. They also use sophisticated instruments, such as particle accelerators and telescopes, to search for direct evidence of dark matter particles.

3. What is the possible impact of dark matter on nucleus decay?

The existence of dark matter can potentially impact the rate of nucleus decay, as dark matter particles can interact with and alter the stability of atomic nuclei. This could lead to changes in the half-life of radioactive elements and affect our understanding of the fundamental processes of the universe.

4. How has the search for dark matter progressed in recent years?

The search for dark matter has progressed significantly in recent years, with new experiments and technologies being developed to detect and study it. While no direct evidence of dark matter has been found yet, scientists have been able to rule out certain theories and narrow down the possible characteristics of dark matter.

5. What are the potential implications of confirming the existence of dark matter?

If dark matter is confirmed to exist, it would revolutionize our understanding of the universe and the laws of physics. It could also have practical applications, such as helping us develop new technologies and energy sources. Additionally, studying dark matter could potentially lead to a better understanding of other mysteries, such as dark energy and the expansion of the universe.
