Quantum computers are computers that use quantum mechanics to store and process information. They are not yet commercially available, but a number of companies and research organizations are working on developing them. If successful , quantum computers could be used for tasks such as simulating molecules and materials, solving optimization problems, and factorizing large numbers.
Black holes are fascinating objects in the universe that come in different sizes. The largest black hole ever discovered is about 40 billion times the mass of our sun. Indirect evidence of black holes has been found by astronomers.

The universe is estimated to contain more than 100 billion galaxies, each containing an average of 100,000 stars. That means there are probably more than 10 trillion stars in the universe! And there are thought to be at least 100 billion planets as well. The largest galaxy currently known is IC 1101, which is about 6 million light years across, while the smallest galaxy known is Segue 2 , at only 600 light years across.
