Without the universal acceptance of the principle of evolution, there is no chance for the serious proposal of holism.

In other words, someone standing at the North Pole on Earth would experience time the same way as someone standing on Mars. When Albert Einstein introduced his Theory of Relativity in the early 20th century, however, he suggested that time wasn't separate from space but connected to it.

Time and space combined to form space-time, and everyone measures his or her own experience in it differently because the speed of light (300,000 km per second) is the same for all observers.

In other words, if all observers have to agree on the speed of light being 300,000 km per second, then they can't agree on the time it takes for other objects to travel relative to them.

Einstein also suggested that space-time wasn't flat, but curved or "warped" by the existence of matter and energy.
