COSMOS - Earth and Galaxy's

Science is one of the most important subjects we learn. For if we know the 'Laws of Nature' on Earth then we can also understand all about the stars, planets, galaxy's in the Universe. I have been watching COSMOS DVD series by Carl Sagan. In this he reminds us that:

• Science is a language that we need to understand all of life including space
• The Laws of Nature are the same everywhere, in every galaxy.
• Light from a candle on earth is the same as the light from a star.
• Chemicals on earth are the same chemicals in outer space.
• That atoms and molecules are governed by physics everywhere.
• The spiral storm patterns in cyclones on earth are the same as the spiral forms on Jupiter.
• Gravity is the same everywhere in space. Gravity is sometimes stronger or weaker in different places, but it is same force.
• Technology is the way species on earth will talk to each other. Earth uses 'Radio Astronomy' and is listening to sounds from space.

IT WOULD BE UNFORGIVABLE TO DESTROY THE EARTH - Humans have several ways that we can destroy all life on earth. So we all need to learn the science behind climate change, and change our actions. WE CAN ALL DO IT TOGETHER.
