Changes in Earth's rotation or revolution

     The Earth changing earthquake's tsunami shifted coastlines and elevation, it caused Earth's rotation to speed up. It occurred when a section of the tectonic plate lying under the Indian Ocean shifted some 15 meters toward Indonesia, sliding further underneath an adjoining plate and caused it to spring forward. Some of the planets mass was drawn closer to the planets center. The day had been shortened by about 2.6 microseconds, or millionths of a second. The Earth's wobble would increase by about an inch as result from the earthquake.

     Neptune's southern hemisphere have been growing bigger and brighter in recent decades. Neptune's southern hemisphere is receiving more solar radiation then the northern hemisphere. Solar heating of the planet's atmosphere can cause convection currents, or the rising and falling of air.

The Big Bang Theory

The Big Bang Theory explains what happened when our universe began and to explain what happend durring and after that moment. Our universe began 13.7 billion years ago. Edwin Hubble invented this theory. Edwin Hubble discovered The Big Bang Theory in 1929.
Most scientists are certain that the universe had a beginning. Galaxies appear to be moving away from and there speed is disproportional to there distance. the observation supports the expansion of the universe and that is was once compacted. If the universe was very hot we should be able to find remnant of this heat.
