The first step in the proton-proton chain produces an antielectron, or positron. What happens to the positron? A. It slowly works its way to the Sun’s surface, where it escapes into space. B. It rapidly escapes from the Sun, traveling into space at nearly the speed of light. C. It is rapidly converted to energy when it meets an ordinary electron, resulting in matter-antimatter annihilation. D. It quickly meets an ordinary electron, forming an electron-positron pair that remains stable. E. It joins with a nearby neutron to form a proton.

1. If a proton is moving at very high speed, so that its kinetic energy is much greater than its rest energy (mc²), can it then decay via p →n + n+? 2. What would an “antiatom," made up of the antiparticles to the constituents of normal atoms, consist of? What might happen if antimatter, made of such antiatoms, came in contact with our normal world of matter?

In 1998, it was announced that the expansion of the universe is accelerating. What does this imply from the perspective of the big bang? a. A force exists that we knew nothing about causes the expansion. b. The universe must be closed. c. The universe is finite. d. The amount of dark matter must be far less than the amount of normal matter. e. The universe must be infinitely old.
