How Big Is Our Universe-Mathematical Analogies by Dr. Anwar Hamdi is a considerably well-researched book on the proportionalities which exist in our Solar System in relation to the Earth. There are fascinating facts in the presentation generally not well known by the general public.
For instance, on Venus a day is longer than an earth year. The largest volcano in our solar system is believed to be on Mars. The top of the Martian volcano is 3 times the size of Mount Everest. The base is approximately 370 miles wide. Since Mars has the largest volcano in our solar system, there could be opportunities to build geothermal energy sites for the Martian cities of the future.
Jupiter is a huge planet in comparison to the Earth. Even though Jupiter is comprised of helium and hydrogen gas, it outweighs our planet Earth by three hundred fifteen times.
The size of Earth compared to the Sun is like comparing a mere lentil to a huge melon. Our Sun is about 5,000 million years old. In star years, this is about the age of a young teenager. One Sun year is equal to two hundred million earth years. The energy liberated by the Sun equals 380 million, million, million, million watts per second. Inside the Sun, temperatures reach 15 million degrees Celsius. The surface of the Sun is 6,000 degrees Celsius.
In our galaxy, there are at least one hundred million black holes with stars collapsing. Black holes are stars in the final stages of life. In a black hole, the laws of Physics as we understand them become altered. The new laws are a complete mystery to human knowledge or imagination. A hypothesis could be that stars implode to a much smaller size with greater density and more tightly packed crystalline structures. In the galaxy M87, there is a black hole with a mass 3,500 million times the mass of our own Sun. Scientists estimate that there are 100 million galaxies in our Universe.
