Unscientific science

PHYSICIST Freeman Dyson once said: "Science is not a monolithic body of doctrine. Science is a culture, constantly growing and changing. … Science has as many competing styles as painting or poetry. The diversity of science also finds a parallel in the diversity of religion."

This diversity Dyson talked about includes many scientists whose scientific ideas reflect their beliefs, not science. Two areas in particular that encapsulate many scientists' unscientific beliefs are the origin of the universe and of life.

Many scientists believe that everything in the universe was created from 'nothing' in a process called 'inflation' just after the Big Bang. Physicist and science fiction writer Lawrence Krauss is one of them.

Eminent physicist George Ellis once said about Krauss's book, A Universe from Nothing, "What he is presenting is not tested science. It's a philosophical speculation, which he apparently believes is so compelling he does not have to give any specification of evidence that would confirm it is true."

Scientists have a very good idea of what happened just after the Big Bang. But science does not explain and quite possibly cannot explain what or who initiated the process that caused the creation of the universe.

Since the Big Bang theory does not answer a number of questions about the universe, the theory of inflation, formulated by MIT's Alan Guth in 1982, has become a sort of religion for many cosmologists. Inflation refers to a brief period at the moment of creation during which the universe expanded faster than the speed of light. Inflation helps scientists answer a lot of questions, but still leaves many unanswered. Many leading scientists do not want to 'believe' in inflation without much scientific evidence to support it.

Steinhardt, who made significant contributions to the theory of inflation, is now a vocal critic of it. Steinhardt has claimed that most cosmologists are uncritical believers.

In an article he co-wrote in 2017, he said, "Cosmologists appear to accept at face value the proponents' assertion that we must believe the inflationary theory because it offers the only simple explanation of the observed features of the universe." He added that inflationary cosmology "cannot be evaluated using the scientific method".

The reality is that inflation attempts to solve only one ' problem': that the observable universe appears to be created with exquisite fine-tuning for life to exist. This is not really a problem of science. Physicist David Albert says that the fundamental laws of nature "have no bearing whatsoever on questions of where the elementary stuff came from".

Along with inflation, many physicists have propagated the multiverse hypothesis with religious zeal in recent years. According to this hypothesis, the universe we live in is just one of an innumerably large number of universes, each with its own set of laws and characteristics. This helps scientists explain why our universe is so finetuned for life's existence. In essence, its proponents argue that if 'our universe' is just one universe in a multiverse, there is a chance that more universes may have conditions suitable for life to exist. However, they still cannot explain what or who initiated the process that created the multiverse.

Many prominent physicists believe that, since it is impossible to prove or disprove the existence of other universes besides our own, the idea of multiverse is not really science. Physicist Sabine Hossenfelder has argued that "Believing in the multiverse is logically equivalent to believing in god, therefore it's religion, not science".

Another issue that is embarrassing to atheists is how life began on Earth and the remarkable complexity of living organisms.
