What is dark energy? Which of the statements BEST summarizes what the Earth and Moon have in common? Based on current evidence, a supercluster is most likely to have formed in regions of space where _____. ie. Invisible dark matter makes up most of the universe – but we can only detect it from its gravitational effects Galaxies in our universe seem to be achieving an impossible feat. Is it matter? Gold is made of one kind of atom-gold atoms. Which of the following statements about large-scale structure is probably not true?

Dark matter is missing stars that have fallen from the sky. b) Dark matter and dark energy are two aspects of the same phenomenon. It is the same as dark energy. Matter and Energy: A False Dichotomy Matt Strassler [April 12, 2012] It is common that, when reading about the universe or about particle physics, one will come across a phrase that somehow refers to “matter and energy”, as though they are opposites, or partners, or two sides of a coin, or the two classes out of which everything is made.

Roughly 70% of the Universe is made of dark energy.

Matter is also different because objects can be made up of different kinds of atoms. Indicate whether each of the following statements concerning viruses and vaccines is true or false. Clusters and superclusters appear to be randomly scattered about the universe, like dots sprinkled randomly on a wall. Physicists suggest a new way to look for dark matter: They believe that dark matter particles annihilate into so-called dark radiation when they collide. One theory suggests the existence of a “Hidden Valley”, a parallel world made of dark matter having very little in common with matter we know. It does not emit electromagnetic radiation. Dark matter can only be detected by its gravitational effects. 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. c. Viruses that cause disease are called retroviruses.

Dark matter can only be detected by its gravitational effects. c. The effect of dark energy is observed only on cosmological scales, while the effect of dark matter has been observed on the scale of galaxies. ... the still futile quest to identify this “dark matter” is a burning question for both particle physics and astronomy. a) Evidence for dark matter has been building for many decades. No DNA is present in a virus. Dark matter has no effect on ordinary matter. The existence and properties of dark matter are inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe.
