SUMMARY

The discussion centers on the concept of invisible matter, specifically dark matter, and its potential existence in different dimensions. Participants assert that the universe comprises mostly invisible matter, which may not be detectable due to its lack of light reflection or emission. It is established that dark matter, while undetectable by conventional means, exerts gravitational effects on visible matter, indicating its presence. The conversation also touches on the idea that other forms of dark matter could consist of numerous sub-atomic particles.

PREREQUISITES
  • Understanding of dark matter and its properties
  • Familiarity with gravitational effects in astrophysics
  • Basic knowledge of sub-atomic particles
  • Concept of dimensions in theoretical physics
NEXT STEPS
  • Research the properties and implications of dark matter in astrophysics
  • Explore the role of gravitational effects in detecting invisible matter
  • Study the characteristics of sub-atomic particles and their potential forms of matter
  • Investigate theories regarding dimensions and their impact on the perception of reality
USEFUL FOR

Astronomers, physicists, and anyone interested in the nature of dark matter and its implications for understanding the universe.

Invisible matter...

since the universe is made up of mostly invisible matter, are they in different dimensions that's why we can't detect them?

such as some say the deads live in the same world that the livings live, except in a different layer or dimension?

No dark matter is just dark.
You can only see things if they reflect light (like planets) or light up themselves (like stars) a lot of the normal mass of the galaxy is dust, cool gas and low mass stars that we can't see because they are too faint.
In addition there may be other forms of dark matter that is made up of large number of sub-atomic particles.

We can detect the presence of this matter because it's mass has a gravitational effect on things we can see.
