Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three lineardimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.
This groundbreaking work laid the foundation for his subsequent contributions to cosmology, black holes, and the nature of singularities in space-time ...Hawking’s career and in the field of cosmology.
... I remove all the particles from the cup of coffee, there is still energy in there due to what we call the quantum vacuum,' he said.This energy of empty space is known as the cosmological constant.
The leading theory has long been that empty space itself produces dark energy ... This energy of empty space is known as the cosmological constant ... If proven right, this would rule out that dark energy is a cosmological constant.
The simplest explanation was that space itself had energy, known as the 'cosmological constant,' which would remain the same forever.The NewDiscovery... model of cosmology, known as Lambda-CDM (ΛCDM).
either the universe itself was created with a rotational motion, or existing cosmological theory must be rethought or reconsidered.James WebbSpaceTelescope findings spark new black hole universe ...
