PSEUDOSCIENCE.

Pseudoscience is like a FAKE science, we call it a 'fringe' because it's like a mask, it thinks it's like REAL SCIENCE but it's not.
Pseudoscience is a claim which is presented as scientific but does NOT adhere to valid scientific methods, there is no backing. Where as Science has an empirical evidence that controles experiments.

Pseudoscience:

• Lack of carefully controled experiments.
• Faulty observations and theories.
• Faulty reasoning.
• Open defiance of scientific concensus.

Science:

• Adheres to valid scientific methods.
• Supporting evidence.

What Pseudoscience is NOT:

1. Informed speculation.

- Attempting to estimate the no of habitable planets and possibilities of life in the universe. But there is real data.

- The absence of data makes it a pseudoscience.

   2.  Polywater involved the claim that some chemists in the 1960's had created a long chain of water molecules. Observation failed due to contamination and impurities (MISTAKE).
