"Absolute space, that is to say, the mark to which it would be necessary to refer the earth to know whether it really moves, has no objective existence"

This quote by Henri Poincare is referring to the principle of absolute area, which is an idea that recommends that space is an outright, unvarying, and independent entity. This idea was promoted by Isaac Newton, who believed that area was an absolute, fixed, and independent entity. Poincare, however, was of the opinion that outright space does not exist. He argued that space is relative, which it is impossible to figure out whether the Earth is actually moving or not without a referral point. He believed that the idea of absolute space was an illusion, which it had no objective presence. He argued that area is relative, and that it is difficult to figure out whether the Earth is actually moving or not without a referral point. He believed that the principle of outright space was an illusion, and that it had no objective presence. Poincare's views on outright area have been influential in the advancement of modern physics, and have helped to shape our understanding of the universe.
