Dark matter is known to exist, due to its gravitational effects. It has not been observed directly.It is believed to be some as-yet unknown particle, which doesn't interact at all, or only very little, with normal matter, or with light, via any force other than gravitation. Thus, for example, it won't absorb or emit light - light will pass right through it.
What else can I help you with?
Why can't dark matter be directly observed?
If it could be directly observed then it would not be called dark matter!
Why can't dark matter be observed?
If it could be directly observed then it would not be called dark matter!
Why is heat abstract?
Heat is considered abstract because it cannot be seen or touched directly, but rather its effects can be observed through changes in temperature or state of matter in objects. It is a form of energy transfer that is measured by its ability to increase the motion of particles in a system.
Dark matter is inferred to exist because?
Dark matter is inferred to exist because of the gravitational effects it has on visible matter in the universe. Observations of galaxies rotating faster than expected and the bending of light around massive objects support the presence of dark matter. However, dark matter itself has not been directly observed or detected.
What is the difference between something that is made up of matter and something that is not made up of matter?
Something made up of matter has physical substance and occupies space, such as solid, liquid, or gas. Something not made up of matter, like thoughts or emotions, is more abstract and does not have physical presence. Matter can be directly measured and observed, while non-material things are often subjective and cannot be physically touched or quantified.
Can a homeowner put a judgment on a contractor?
The matter has to go to court. A homeowner cannot do it directly.
Can you make a box out of dark matter?
Not much is currently known about the structure of dark matter. For a start, it was never directly observed. There is only indirect evidence for dark matter. Therefore, it isn't know what types of structures it forms, if any.
Why chemists use models to study submicroscopic matter?
Chemists use models to study submicroscopic matter because it helps them visualize and understand phenomena that cannot be directly observed. Models allow chemists to make predictions and hypotheses about the behavior of particles at the atomic and molecular level, leading to new discoveries and advancements in the field of chemistry.
Is a quark the same as an energy level?
No, Higgs Boson is a theoretical particle yet to be observed directly or indirectly by humans. Quarks on the other hand have been observed directly and indirectly. Also, the Higgs boson is responsible for a field, however quarks are responsible for matter, and are the basic constituents of the nuclei in atoms.
Why is anything you can touch and pick up not a good definintion of matter?
This definition is incomplete because there are forms of matter, such as gases and plasma, that cannot be physically picked up or touched directly. Matter encompasses everything that has mass and takes up space, including solids, liquids, gases, and plasma.
Why can't the dark matter in galaxies be made of neutrinos?
Dark matter in galaxies cannot be made of neutrinos because neutrinos are too light and move too quickly to account for the gravitational effects observed in galaxies. Neutrinos also interact weakly with other particles, making them unlikely candidates for the majority of dark matter in the universe.
Does dark matter have an electrical charge?
Based on just a few simple things that popular news magazines mentionwhen they talk about the weird subject of dark matter, we're pretty safein assuming that dark matter has no electrical charge.-- No place in the universe is known to have dark matter.-- Dark matter is hypothesized ("just a theory") but has never been observed.-- It can't have an electrical charge, because if it did, then---- it would interact with other observed electrical charges and observed electromagnetic fields,------ which is exactly what it doesn't do,-------- which is why it has never been observed and is called "dark" matter.
