Every Atom in Your Body Came From A Star and Other Quotes by by Lawrence Krauss

  • The amazing thing is that every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way they could get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.
    • "A Universe From Nothing" by Lawrence Krauss, AAI 2009 (16:50-17:23) - I won't forget Jesus, but that is quite a nice thing you started with on the first line. It is nice that stars paid a part of the price for my bodily creation but the creator and the originator must not be forgotten neither should we be ungrateful. 
  • In 5 billion years, the expansion of the universe will have progressed to the point where all other galaxies will have receded beyond detection.  Indeed, they will be receding faster than the speed of light, so detection will be impossible.  Future civilizations will discover science and all its laws, and never know about other galaxies or the cosmic background radiation.  They will inevitably come to the wrong conclusion about the universe......We live in a special time, the only time, where we can observationally verify that we live in a special time.
  • The other thing people don't realise about science which differentiates it from religion is that, the most exciting thing about being a scientist is not knowing and being wrong. Because that means there is a lot left to learn.
  • It is a shame when nonsense can substitute for fact with impunity.
