Answers
What Is a Black Market?
A black market is economic activity that takes place outside government-sanctioned channels. Black market transactions usually occur “under the table” to let participants avoid government price controls or taxes.
What is black matter?
Scientists believe that dark matter may account for the unexplained motions of stars within galaxies. Computers play an important role in the search for dark matter data. They allow scientists to create models which predict galaxy behavior. Satellites are also being used to gather dark matter data.
What is Time Paradox?
A temporal paradox, time paradox, or time travel paradox is a paradox, an apparent contradiction, or logical contradiction associated with the idea of time and time travel. In physics, temporal paradoxes fall into two broad groups: consistency paradoxes exemplified by the grandfather paradox; and causal loops.
