Quotes by Willem de Sitter

The general theory of relativity has opened up new possibilities for the structure of the universe, which were unthinkable before.

On the Relativity of Inertia. Remarks Concerning Einstein's Latest Hypothesis 1917

The curvature of space-time is not merely a mathematical construct, but a physical reality that determines the paths of celestial bodies.

On the Relativity of Inertia. Remarks Concerning Einstein's Latest Hypothesis 1917

We must distinguish between a universe that is static and one that is evolving.

On the Relativity of Inertia. Remarks Concerning Einstein's Latest Hypothesis 1917

My model of the universe, the 'de Sitter universe,' is empty of matter but still expanding.

On the Relativity of Inertia. Remarks Concerning Einstein's Latest Hypothesis 1917

The expansion of the universe is a consequence of the field equations of general relativity, even in the absence of matter.

On the Relativity of Inertia. Remarks Concerning Einstein's Latest Hypothesis 1917

The 'de Sitter universe' provides a limiting case for understanding the dynamics of the cosmos.

On the Relativity of Inertia. Remarks Concerning Einstein's Latest Hypothesis 1917

The concept of an expanding universe was initially met with skepticism, but observational evidence has since supported it.

The Astronomical Consequences of the Theory of Relativity 1931

The universe is not a static entity, but a dynamic system undergoing continuous change.

The Astronomical Consequences of the Theory of Relativity 1931

The red-shift of distant galaxies is a direct consequence of the expansion of space itself.

The Astronomical Consequences of the Theory of Relativity 1931

The universe is not infinite in extent, but rather finite and unbounded, like the surface of a sphere.

The Astronomical Consequences of the Theory of Relativity 1931

The general theory of relativity has revolutionized our understanding of gravity and the structure of the cosmos.

The Astronomical Consequences of the Theory of Relativity 1931

The universe is a grand experiment, and we are but humble observers trying to decipher its laws.

The Astronomical Consequences of the Theory of Relativity 1931

The beauty of physics lies in its ability to explain the most complex phenomena with elegant mathematical equations.

The Astronomical Consequences of the Theory of Relativity 1931

The pursuit of knowledge is an endless endeavor, and we must always remain open to new ideas.

The Astronomical Consequences of the Theory of Relativity 1931

The universe is full of wonders, and it is our privilege to explore them.

The Astronomical Consequences of the Theory of Relativity 1931

The interplay between theory and observation is crucial for the advancement of science.

The Astronomical Consequences of the Theory of Relativity 1931

The universe is a dynamic system, not a static one, and its evolution is governed by the laws of physics.

The Astronomical Consequences of the Theory of Relativity 1931

The concept of an expanding universe was a radical idea, but it has been confirmed by observations.

The Astronomical Consequences of the Theory of Relativity 1931

The universe is not empty, but filled with matter and energy, which influence its curvature and expansion.
