Discussion Overview

The discussion revolves around the existence and behavior of various types of matter and energy, including antimatter, dark matter, negative mass, dark energy, and negative energy. Participants explore theoretical and experimental perspectives, as well as the implications of these concepts in physics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants question whether antimatter, dark matter, negative mass, dark energy, and negative energy are confirmed phenomena.
  • One participant notes that antimatter is created and destroyed in particle colliders, while dark matter is theorized but not detected.
  • Negative mass is discussed in terms of negative effective mass, which arises from particle behavior rather than being a standalone entity.
  • Dark energy is theorized but remains unconfirmed, with some participants mentioning its role in cosmology.
  • There is uncertainty regarding whether these types of matter exhibit wave behavior, as dark matter and other exotic forms have not been observed.
  • Participants discuss the relationship between energy and mass, with one suggesting that energy already has mass in certain contexts, such as gravitational systems.
  • Some participants express frustration over the perceived lack of research by the original poster, while others advocate for understanding the complexity of the topics discussed.

Areas of Agreement / Disagreement

Participants express differing views on the confirmation of various types of matter and energy, with some asserting that certain concepts are theoretical while others provide examples of experimental evidence. The discussion remains unresolved regarding the definitive status of these topics.

Contextual Notes

Participants reference various scientific concepts and theories without reaching consensus on definitions or the implications of these ideas. The discussion includes assumptions about the reader's prior knowledge and the complexity of the topics at hand.

Who May Find This Useful

This discussion may be of interest to individuals exploring advanced topics in physics, particularly those related to theoretical and experimental aspects 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:
What about dark energy and negative energy?

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:
Do these types of matter behave as wave also?

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:
