The development process began with extensive research and vigorous peer review, to ensure the quality of the content and the level of instruction.

You will know that the first stars contained no heavy elements, making them different from later generations of stars You will understand the physical conditions under which the first stars formed
- https://phys.libretexts.org/Courses/Chicago_State_University/PH_S_1150%3A_Basic_Astronomy/12%3A_Gravitational_Lenses/12.04%3A_Weak_LensingYou will understand the difference between strong and weak lensing. You will understand that weak lensing reveals the presence of dark matter throughout the Universe.

In the case of Earth, Mars, Jupiter, or any of the planets farther out in the Solar System, we could plug in the total mass of the Sun for M (note that this is the case even for Earth, which is orbiting just at the edge of our spread-out Sun).

You will understand that mass and energy are different aspects of the same underlying quantity, and that is the total of mass and energy that is truly conserved. You will know that a tiny amount of matter can release a great deal of energy. You will understand that it is possible to produce a pair of charged particles from an energetic photon, and that the annihilation of a particle-antiparticle pair releases energy.

(Do not include mistakes, only unavoidable measurement imprecision.) If you obtained any numerical values for the accuracy of your measurements during the activity, note those here. Using either the formulae or the graphs from the interactive activity in the chapter, answer the following:

The relatively modern discovery of the accelerated expansion of the Universe is described and different possibilities for the nature of dark energy are discussed. Measurements of dark energy and dark matter and of normal matter and energy are combined within the cosmic concordance model, and the implications of this model are discussed.
