Based on physical evidence, scientists have concluded that the planet earth probably formed years ago, and the first life evolved as early as years ago.

Hybrid instruments that play sounds that are part sampled and part synthesized are known as:

The small molecule cyclic amp (camp) takes about 0.2 second to diffuse 10 μm, on average, in a cell. suppose that camp is produced near the plasma membrane on one end of the cell; how long will it take for this camp to diffuse through the cytosol and reach the opposite end of a very large cell, on average? assume that the cell is 200 μm in diameter.

The big bang theory suggest that the universe is about - 300 million years old - 4.6 billion years old - 30 billion years old - 13 billion years old
