Electromagnetism is one of the four fundamental forces of the universe. What is some supporting evidence that supports this claim? Describe at least one example.
The following quotation is taken from the article “Quantum Black Holes”, by Bernard J. Carr and Steven B. Giddings, in the May 2005 issue of Scientific American. "The total time for a black hole to evaporate away is proportional to the cube of its initial mass. For a solar-mass hole, the lifetime is an unobservably long 1064 years." a. Recall that the solar mass is 2 × 10³0 kilograms. Write a formula for the lifetime, L, of a black hole as a function of its mass, m. Start by finding the value of the constant k, then write your function using the letter k (rather than its value in scientific notation). For example, for a direct variation you would write “L(m) = km”. k = a × 10¹ where a = L(m) = b. The present age mass = c × 10ª kg, where c = A and b = = of the universe is about 10¹0 years. What would be the mass of a black hole as old as the universe? ID and d = J
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.
