The old Lambda-Cold Dark Matter (LCDM) model furthered Einstein's cosmological constant.
The researchers' calculations show that if gravitational waves are found to travel at the speed of light, this would rule out alternative gravity theories, with no dark energy, in support of Einstein's Cosmological Constant.
Even if Einstein's cosmological constant (repulsion) was considered to be accurate for a long time, in modern physics the mechanical worldview of the "gravity and repulsion" was rebuilt, disposing "gravity" to explain the mutual attraction between objects, and "repulsion" to define the mutual exclusion between objects.
