Our two best theories of nature, quantum mechanics and general relativity, are incompatible with each other in many ways – leaving physicists to dig deeper.
The key to understanding why life is not explainable in current physics may be to reconsider our notions of time and information.
Life may be using quantum mechanics to its advantage.
According to a school of thought known as QBism, quantum mechanics is a guide to action.
Some physicists don’t believe that quantum mechanics is a perfect description of objective reality.
From string theory to observations, the multiverse theory is far from safe.
Some physicists believe we could one day find evidence of other universes.
It seems we are pretty lucky to have gravity that is just right for life.
In the multiverse, a few universes should, statistically speaking, be life-friendly.
If we accepted that the future could influence the past, we could get rid of many counter-intuitive aspects of quantum mechanics.
Physics makes a lot of assumptions about time that may be getting in the way of understanding the fourth dimension.
