Question 4 options: the big bang theory the existence of homologous structures the similarities in body systems such as the nervous and circulatory systems the time period in which an embryo develops 5.17 Unit Test: History of Life on Earth, Part 1 Pool 5 Write a short essay in which you describe what we mean by dark matter, describe the evidence for its existence, and discuss your opinion about the strength of the evidence. c) Dark matter is inferred based on unseen gravitational effects in galaxies. It's hard to get an answer that bad. Which of the following is evidence for the existence of dark matter? The motions of stars in galaxies, the orbits of galaxies in galaxy clusters and the temperature of the gas in galaxy clusters It has been shown from recent observations that the universe is … 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.

These particles wo The rate of expansion of the universe is speeding up. Which of the following is evidence for the existence of "dark matter" in the universe? The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter.

The space between stars … 7 Independent Pieces Of Evidence For ... the full suite of evidence points towards the incontrovertible existence of dark matter. Roughly 70% of the Universe is made of dark energy. The outlying stars in a galaxy appear to orbit more rapidly than expected. b) Dark matter and dark energy are two aspects of the same phenomenon.

Another explanation for dark energy is that it is a new kind of dynamical energy fluid or field, something that fills all of space but something whose effect on the expansion of the universe is the opposite of that of matter and normal energy. What is dark energy?

So the mystery continues. We still don't know what dark energy is, but it’s thought that it makes up 68 percent of the universe's total matter and energy.

Which of the following is not true about dark matter? Stars eventually use up their fuel and stop shining. The density of dark matter in an expanding universe decreases more quickly than dark energy, and eventually the dark energy dominates. Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies.

Evidence for Dark Matter Evidence for dark matter in spiral galaxies In spiral galaxies like the Milky Way, we derive the gravitational mass from observing the motions of stars and gas clouds in the disk as they orbit the center . Overall, how convincing do you consider the case for the existence of dark matter? Some particle theorists have built WIMPs into their unified force theories and into the inflationary scenario of the evolution of the universe so popular today. Dark matter can’t be seen or detected by any of our instruments, so how do we know it really exists? Dark matter makes up about 25%.
