Our Mathematical Universe – Max Tegmark

The Cosmic Microwave Background Radiation

The Cosmic Microwave Background Radiation

Scientists and mathematicians make the best philosphers; they are always trying to ask and answer the biggest questions.

This is what I learnt from Our Mathematical Universe by Max Tegmark:

  • The moment we live in is given value by the memories we have. As we go through life, we build up a model of the world around us and this model is stored in our memories and these memories are what give richness to our experiences. If I’m alone and I feel lonely, it’s only in the context of my memories that I feel lonely. If I’m alone and contented, it’s only in the context of my memories that I feel contented. The fact that I’m alone isn’t what makes me feel lonely or contented, it’s the memories I have. A long life may feel less valuable than a short life if the memories of the long life are dull while the memories of the short life are vibrant. I want to do more things and add more memories to my life.
  • The universe is big and if a multiverse exists, it’s unfathomably huge. Statistically, if the universe continues far enough, there is probably an exact copy of you within 10^10^118 metres (a super super long way, but still cool to think about). And of course, if the universe is infinite, then there are infinitely many copies of you!
  • Maybe there is something special about us. There are hundreds of billions of stars in our galaxy and there are hundreds of billions of galaxies in our observable universe. There should be trillions of planets capable of supporting life, yet when we look into the cosmon, we seem to be eerily alone. Perhaps we really are alone. Perhaps intelligent life is rarer than some people think. Perhaps we really are the only species that tries to unravel the secrets of the universe.
  • What is the meaning of life? Max Tegmark observes that people can find meaning in life through two different views of the world. Some get meaning from a top-down view, where they feel part of something bigger than themselves. Others get meaning from a bottom-up view where the small things in life are enough. And some people find meaning in both.

 

I loved this book sooo much! You can find it here:
