O primeiro deles é provavelmente "Hora comum" de James Blish.
Garrard travels around the speed of light to reach Alpha Centauri.
However, instead of experiencing the same relativistic time as his
ship, his own time passes about two hours for every second on the

Referência cruzada no ISFDB, a antologia O Tesouro Arbor House de Ficção Científica Moderna, editado por Martin H Greenberg e Robert Silverberg e publicado pela primeira vez no 1980, continha essas duas histórias.
Não consigo identificar a terceira história como estando nessa antologia, mas poderia ser “Bordado em preto” por Larry Niven, que não foi amplamente antologizado.
Two spacemen found a new planet. They observed the coastlines of all
the continents were "bordered in black" (I think it was actually an
infrared view). When they explored they found the planet had been
artificially terraformed to act as a food producing planet. All the
natural life had been exterminated and the oceans had been seeded with
some algae that would be harvested for food. But the planet had been
abandoned and the human-like caretakers had been forgotten and left
behind. The black border was the descendants of the original
caretakers who now crowded up against the beaches to get the algae
which was the only food on the planet.
