The concept of an "obvious truth about the world" is subjective and can vary depending on individual perspectives and beliefs. Different people may consider different things to be obvious truths based on their cultural, social, religious, or personal experiences.
However, some concepts are generally considered as widely accepted and self-evident truths by many people. Here are a few examples:
The Law of Gravity: The force of gravity, which causes objects to be attracted to one another, is considered an obvious truth in the physical world.
Human Mortality: All living beings, including humans, are mortal and will eventually die.
Earth's Spherical Shape: The Earth is approximately spherical, and this has been confirmed through various scientific observations and evidence.
Cause and Effect: Events have causes, and actions have consequences. This principle underlies much of our understanding of the world and is central to scientific reasoning.
Time's Unidirectional Flow: Time moves forward in a linear direction from past to present to future, and this notion is an inherent part of our experience.
Universal Constants: Certain physical constants, such as the speed of light in a vacuum or Planck's constant, are believed to be consistent throughout the universe.
Human Empathy: The capacity for empathy and the ability to experience and understand the emotions of others is a fundamental aspect of human nature.
Biological Evolution: The theory of biological evolution, which explains the diversity of life on Earth through natural selection and adaptation, is widely accepted in scientific communities.
Basic Arithmetic: Fundamental arithmetic operations, such as addition, subtraction, multiplication, and division, are universally understood and applied.
It is essential to recognize that what may seem like an obvious truth to one person may not be perceived the same way by others. Additionally, our understanding of the world is continually evolving through scientific discoveries and advancements in knowledge, challenging and refining our perception of what is considered obvious truth.
