SUMMARY

This discussion centers on the existence and properties of antimatter, dark matter, negative mass, dark energy, and negative energy. Antimatter is confirmed to be created and destroyed in particle colliders, while dark matter and dark energy remain theoretical and unconfirmed. Negative mass is not recognized as a physical entity, but negative potential energy exists in various forms. The relationship between energy and mass is governed by Einstein's mass-energy equivalence, indicating that energy forms can contribute to mass in specific contexts.

PREREQUISITES
  • Understanding of Einstein's mass-energy equivalence (E=mc²)
  • Familiarity with quantum physics concepts, including virtual particles and the Casimir effect
  • Knowledge of cosmology and the role of dark matter and dark energy
  • Basic principles of particle physics and antimatter production
NEXT STEPS
  • Research the properties and applications of antimatter in particle physics
  • Explore current theories and experiments related to dark matter detection
  • Investigate the implications of dark energy in cosmological models
  • Study the concept of negative potential energy and its relevance in quantum mechanics
USEFUL FOR

Students and researchers in physics, cosmology enthusiasts, and individuals interested in advanced concepts of matter and energy.

Hello. Questions: Are antimatter, dark matter, negative mass confirmed that they exist and exhibit as phenomena? What about dark energy and negative energy? Do these types of matter behave as wave also? Do they exhibit such behaviour? About those types of energy i said, can they be transformed to mass by using the Einstein equivalence of mass and energy formula? Thank you.

What research have you done on this so far? What have you found?
 
I think antimatter is proposed by quantum theory, so does negative mass, dark matter so far is not confirmed but is on research, same about dark energy. Negative energy is something i read from a scientist about the total physical energy of the universe that is equal to zero, where there is positive and negative energy and their sum is equal to zero. About the other things i do not know. I am sorry.
 
So, it sounds like you have done no research at all, you just have vague impressions from various reading. Try at least Googling some of the terms.

Antimatter is regularly created and destroyed at many different locations on Earth, specifically in particle colliders.

Dark matter is theorized to exist, but has never been detected.

Negative mass doesn't exist except in the sense of negative effective mass, which, much like a positively charged hole in semiconductors, arises from the bulk behavior of the particles within the material and isn't real. (Unless you want to get philosophical about what 'real' means, which is beyond the scope of this thread)

trees and plants said:

Dark energy, like dark matter, is also theorized to exist but has yet to be confirmed.

Negative energy exists in various formats. Negative potential energy is one example, along with some complicated examples from quantum physics like virtual particles and the casimir effect. It also comes into play in cosmology.

trees and plants said:

Unknown, as we haven't observed dark matter or other types of exotic matter.

It's not that they can or can't be transformed into mass, it's that they already have mass. For example, the potential energy of two objects orbiting about a common center of mass under gravity must be taken into account when determining the mass of the system. The mass associated with dark energy plays a dominant role in cosmology if understand things correctly.

Don't be too harsh. These are complicated topics that are not easy to understand, even for someone like myself who has been around PF for a decade.

No argument there, I just felt that he should at least do SOME research on his own before we spoon feed him answers.

For example, it's takes about 3 seconds on Google to find out that anti-matter is in use every day around the world, not just a theoretical construct.

How is he going to learn to do his own research if we don't expect any from him?

3 seconds if you already know it is. Potentially much longer if you don't.

I typed his first sentence into Google verbatim. The second sentence of the first link gives him his answer for antimatter. Is that too much effort to expect?

It looks like @trees and plants is on a Spring Break vacation for 10 days, so this thread can be tied off for now. Thanks for trying to help him/her out in various ways. :smile:
