Yes, that is correct. For more information, read online sources (for example, the Wikipedia) about the topic "Big Bang".
No. The sun is expanding, but extremely slowly. It is estimated that Earth will become uninhabitable in about 800 million years.
The chromosphere and/or the corona.
As far as scientists know, no. And because the gravity on the moon is too small to support an atmosphere, and the temperatures fluctuate too rapidly and extremely it is highly unlikely that life could exist.
Not yet.When they say not yet, scientists have shown that bacteria on mars or similar planets could be possible, they just haven't found it. In 2004, a team of scientists dug a hole 4000 feet deep into volcanic rock in Hawaii. They found bacteria on living conditions extremely similar to those on mars. Although no bacteria has been found on mars, or anywhere else, we have the proof that it may be able to exist.
To be extremely general with it, scientists and explorers are normally both apart of the human race and they both make discoveries. I don't know what exact information you are looking for or else I would be able to answer this in a better way.
The noise coming from a lightning is created when the speed of sound is broken.The heat from the electricity raises the temperature of the surrounding air extremely. Since the lightning is so fast, the air has no time to expand.The heated air is compressed and soon the air explodes forming a shock wave. Like an explosion, the rapidly expanding waves of compressed air create a loud burst of noise.
The rocket engine is based on the scientific principle expressed in the phrase: "For every action, there is an equal and opposite reaction" This is a rough approximation of Sir Isaac Newton's third law of motion. His three laws of motion formed the foundation of the science and methodology that came to be known as classical mechanics. The rocket fuel is ignited at the tail of the rocket. The somewhat uncontained explosion, or extremely rapid expansion of gases, pushes out in all directions. That rapid expansion pushes against the rocket, advancing the rocket's motion in the direction of the nose. In atmosphere, the rocket gets an advantage as the extremely rapid expansion pushes against the atmosphere, and transfers more energy to the rocket. In space, the action still works, as the gas is pushing still expanding in all directions, and so still expanding against the end of the rocket pushing it forward. It is the EXTREMELY rapid expansion, due to the continuous "explosion" of the burning fuel that allows this gas to exert enough pressure to move the heavy rocket. The same amount of expansion stretched out over several days might not even be noticeable!
That it expanded, and still is expanding, from an extremely dense and hot state.
An exhaust system expansion box allows for the cooling of extremely hot air. The hot exhaust is cool in the expansion box before exiting the tailpipe.

Maybe. Nobody knows, perhaps there was a extremely tiny particle before the creation of the universe, and then an error occurred inside it expanded to the size of a galaxy! And the universe is still expanding. But some say it was not an accident but instead it was the work of God, since there should be somebody to put that extremely tiny particle which is responsible for all this. But, then the ultimate question arises is, who created God? Scientists have been fighting about this ever since.

No. The sun is expanding, but extremely slowly. It is estimated that Earth will become uninhabitable in about 800 million years.
Theoretically there could be, the Universe is ever expanding and has millions of galaxies. It is possible, though extremely unlikely, an identical galaxy to that in Star Wars is out there.
The universe began with a rapid cosmological expansion from an extremely hot and dense state.

There are a variety of thermometers, and they can be extremely accurate. Sometimes scientists need to measure temperature to the thousandth of a degree Kelvin.
