michaelkelly8798 raises a fair point about scientific theories. Many people grab onto whatever scientific theory is currently in vogue and proclaim it as absolute truth. Often this is a way for the slower minded to avoid thinking about a topic. They just want to be told the answer. People who just want to be told the answer often get upset and angry when an answer they have already accepted is questioned.

Uncorrupted science is a search for truth. Plausible ideas and concepts that are not incompatible with current observations are scientific theories. Proven reproducible facts are scientific laws. Theories are often wrong no matter how many scientists ascribe to them. The trashcan of history is full of discarded theories that were once widely embraced by scientists.

The best modern example I can think of is the current scare mongering over man made global warming. The media, the majority of climate scientists, and indeed even the Pope are on record proclaiming that we are cooking the planet and to question this narrative is to be anti-science and worthy of public shamming.

The reality however is that there are very compelling reasons to doubt this uniform presentation of doom. It just takes a genuine scientist and a superior idea to do so.
 
Professor Valentina Zharkova is a tenured professor Mathematician and Astrophysicist. Her model of solar cycles is entirely reproducible, and accurately accounts for prior global temperature variations with a greater then 90% accuracy. It also almost entirely repudiates the current global warming narrative so it is ignored.

How many people will take the 90 minutes to watch Professor Zharkova's presentation?  Very few most will prefer to just be told the answer by the media the Pope or whoever else is whispering in their ear.

Truth is like that. Often hidden away in the background present but not demanding or forceful. It patiently waits for people to get tired of their current falsehood and approach it when they are ready.
