Dark nebulae. What is dark energy? There are large clumps of galaxies. What is dark energy? Dark matter must be stable with a very long lifetime, persisting over the universe’s present age of 14 billion years. 1) Why do we call dark matter "dark"? c. Exotic particles like "axion" that weakly, if at all, interact with light. Answer a.Repeatability builds trust in the results of investigations and builds respect for the people performing them in the scientific community. A. C) Dark matter is present in individual galaxies, but there is no evidence that it can exist between the galaxies in a cluster.
C. It is very large and invisible.

Dark matter does not reveal its presence by emitting any type of electromagnetic radiation. Dark matter emits no light, and cannot be directly observed, but scientists think that it and dark energy make up most of the mass of the universe. Dark matter is a type of matter, whose composition is unknown and which corresponds to 80% of the matter in the universe. Hidden black holes, white dwarfs and brown dwarfs.

State of Matter of Fire: What about fire? d. Neutrinos In such geometrical background matter and (negative mass and It shows that dark matter cannot be made up of primarily normal matter, such as protons and neutrons Stars of the first generation were: more massive than today's average star Why Light and Heat Aren't Matter: There's a reason forms of energy don't qualify as matter. Since they are charged particles they interact with electromagnetic force which means they can absorb and emit light and as such, cannot be DARK matter. A) We cannot detect the type of radiation that it emits. Which of the following best summarizes what we mean by dark matter?

Which of the following is strong evidence of the presence of dark matter? Dark matter does not reveal its presence by emitting any type of electromagnetic radiation.

The area becomes too concentrated with stars. Dark matter makes up about 25%. Dark matter exists: Observations disprove alternate explanations by International School of Advanced Studies (SISSA) Acceleration as a function of radius in NGC 4455, one of the studied galaxies. Is it matter?

matter-dark matter couple is proposed, through a two-points cover of a M4 manifold, forming a two folds ( F , F ) space-time structure. D. Dark matter can only be detected using light beams. More is unknown than is known — we know how much there is, and we know some of its properties; other than that, dark energy is a mystery — but an important one. Which of the following definitely cannot account for the composition/nature of Dark Matter? b. which of the following best describes dark matter? The matter from stars, gas, and dust cannot account for the observed rotation curve of galaxies. Dark matter could be white dwarfs, the remnants of cores of dead small- to medium-size stars. c. Or dark matter could be neutron stars or black holes, the remnants of large stars after they explode.

Dark matter emits no light, and cannot be directly observed, but scientists think that it and dark energy make up most of the mass of the universe. b.False claims usually go unnoticed, since evidence is easily duplicated through repeated trials. The Higgs boson cannot be the explanation for dark matter for a very simple reason. Dark matter emits light exclusively in the infrared, so our eyes can't detect it (hence, "dark"). It mostly sits in space doing nothing except providing additional gravitational interaction with ordinary matter. Dark matter makes up about 25%. More is unknown than is known — we know how much there is, and we know some of its properties; other than that, dark energy is a mystery — but an important one.
[Hint] Matter that we have identified from i in any wavelength of light Matter that may inhabit dark areas o Matter consisting of black holes 2 .Which of the following best summarizes what we mean by dark energy? Select one: a. a. Axions b. Positrons c. Photinos d. Neutrinos.
