Wormholes are solutions to the Einstein field equations for gravity that act as "tunnels," connecting points in space-time in such a way that the trip between the points through the wormhole could take much less time than the trip through normal space

Explanation:
Evolutionary psychology is based on the theory of evolution, which states that behavior is much regulated by the principle of adaptation among others.

In the supply curve and the demand curve, the equilibrium is reflected where the two curves intersect.
<u>Explanation:</u>
Equilibrium is fundamentally the condition in which the factors involved in the operation achieve balance of values with respect to each other. In the discipline of market economics, two major factors involved are that of supply and demand.
The equilibrium between supply and demand is achieved when the demand for a commodity or a service in the market is equal to the supply of the respective commodity or service.
When represented graphically, the condition of equilibrium is depicted through the intersection of the demand and supply curves.
