WE ARE ALL DESIGNIST:
The multiverse: Our universe is suspiciously unlikely to exist--unless it is one of many, says physicist (Martin Rees, 3/15/23, The Conversation)
The conditions of the universe can be described through its "fundamental constants"--fixed quantities in nature, such as the gravitational constant (called G) or the speed of light (called C). There are about 30 of these representing the sizes and strengths of parameters such as particle masses, forces or the universe's expansion. But our theories don't explain what values these constants should have. Instead, we have to measure them and plug their values into our equations to accurately describe nature.The values of the constants are in the range that allows complex systems such as stars, planets, carbon and ultimately humans to evolve. Physicists have discovered that if we tweaked some of these parameters by just a few percent, it would render our universe lifeless. The fact that life exists therefore takes some explaining.
