What is an example of objective truth?

An example of an objective truth is a fact or statement that is true independently of personal opinions, beliefs, or feelings. Objective truths are based on empirical evidence and can be verified through observation, measurement, and the scientific method. Here are a few examples of objective truths:

1. Water boils at 100 degrees Celsius (212 degrees Fahrenheit) at sea level under normal atmospheric pressure.
2. The Earth revolves around the Sun, and this fact can be confirmed through astronomical observations and calculations.
3. The chemical formula for water is H2O, consisting of two hydrogen atoms and one oxygen atom.
4. The force of gravity attracts objects with mass toward each other, and this can be measured and predicted using the laws of physics.
5. The speed of light in a vacuum is approximately 299,792,458 meters per second.
6. The Earth is an oblate spheroid, meaning it is mostly spherical in shape, and this can be confirmed through measurements and satellite imagery.
7. Oxygen is necessary for human respiration, and the chemical processes involved in respiration are well-documented and understood.
8. The chemical element with the atomic number 6 is carbon. This is a fundamental fact in chemistry.
9. The acceleration due to gravity on the surface of the Earth is approximately 9.81 meters per second squared (m/s²).
10. Water freezes at 0 degrees Celsius (32 degrees Fahrenheit) at sea level under normal atmospheric pressure.
11. The sum of the angles in a triangle always equals 180 degrees, a fundamental geometric truth.
12. The speed of sound varies depending on the medium it travels through; for example, it is approximately 343 meters per second in dry air at room temperature.
13. DNA carries genetic information and is composed of four nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G).
14. The periodic table of elements organizes chemical elements based on their atomic number and properties, providing a universally accepted framework for chemistry.
15. The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed, only converted from one form to another.
