Daily cosmobite: what is the Universe made of?

Only five per cent is ordinary matter like the matter in people, bricks and air. The rest of the Universe is mysterious dark matter or even more mysterious dark energy.

One response to “Daily cosmobite: what is the Universe made of?

  • If known matter makes up less than 5% of the known universe (which itself is most likely a tiny part of the unknown universe or universes, it seems to me that all claims about the nature of matter, and the cosmos as a whole should be tentative at best as possibilities, perhaps even probabilities but with no claim of certainty. Knowing how to apply what little we know about the nature of reality is not the same as understanding it.

    The appropriate and only reasonable attitude for science, it seems to me, is one of profound humility and genuine open-mindedness. Too often though, scientists make sweeping claims what is and what is not, most of which are based on what understanding can be inferred from observed effects of forces and processes that cannot explain. In truth, however, most of reality remains a profound mystery that could and mostly likely does encompass many probabilities that science refuses to even consider, and many more of which we are totally ignorant.
