• Evolution: Theory

    Charles Darwin’s Theory of Evolution is based on three basic principles: reproduction, mutation and selection. These fundamental principles are all that is needed to create the near infinite variety of life that we can see now. Reproduction, as described in the definition of life, is the ability to create offspring. Reiterative computer programs make copies [...]
  • The origin of life

    Nobody knows exactly how life began, nor have they been able to reproduce it’s creation in a laboratory. However the preconditions for life: amino acids, lipids (fats) and other small molecules forming the fundamental blocks for life; some form of selection pressure to favours certain molecules over others; and the gradual increase in complexity of [...]
  • A definition of life

    Life is not a discrete entity, it needs to be defined. Whilst on initial inspection we can say that a dog is alive whilst a rock is not, when getting to the level of viruses, fungi, bacteria and other single cell organisms the distinction becomes blurry. Accepted definitions of life require the following attributes: organisation, [...]
  • The solar system and Earth

    As you will read in many children’s books, the current theory is that the Solar System began as large rotating cloud of gas that slowly collapsed under the force of it’s own gravity to form the large objects that are we now find in our solar system: the Sun and it’s satellites (planets, asteroids, comets). [...]
  • The expanding Universe

    The Universe is comprised of many galaxies and it appears to be expanding. This implies that there was a beginning, called the Big Bang.
  • The substance of the Universe

    The Universe is a very mysterious place. At this point in time there is no scientific explanation that fully describes it (called a Theory of Everything or T.O.E.).
