... Electric and magnetic (electromagnetic) forces can be attractive or repulsive, and their sizes depend on the magnitudes of the charges, currents, or magnetic strengths involved and on the distances between the interacting objects. Gravitational forces are always attractive. There is a gravitational ...

... Scientists also look for the oldest stars and other celestial bodies in the universe. By studying these bodies, understanding how long it took them to form, and knowing how old they are, scientists can create a bound for the age of the universe. That is, if the oldest star is so many billion years o ...
