In cosmology, the solution of the equations of motion toward the past stops abruptly ... If we only have initial conditions, the deterministic limit gives the equations of classical physics, for ...

In cosmology, the solution of the equations of ... the deterministic limit gives the equations of classical physics, for example, Newton's laws. I derived the corresponding equations in the ...

The universe’s expansion may be driven by “transient temporal singularities”—rapid, invisible bursts of energy—rather than dark matter or dark energy, according to new research that challenges the ...

Cosmology is the science of studying the Universe as a whole ... on the nature and properties of the dark matter particle in ways that are complementary to what can be gleaned from colliders. For ...

People are still puzzling over why nearby objects and distant galaxies move away from us at different speeds. There may now ...

Sir: Despite originating in vastly different cultural and geographical contexts, Igbo cosmology and Chinese Buddhism share significant conceptual overlaps. Both belief systems recognise ...

SFU cosmologist Levon Pogosian receives a prestigious Buchalter Cosmology Prize for his work on “Relieving the Hubble Tension with Primordial Magnetic Fields,” co-authored with Karsten Jedamzik ...

Vivian Poulin asks if the tension between a direct measurement of the Hubble constant and constraints from the early universe could be resolved by new physics.

(via Sabine Hossenfelder) Cosmology, the branch of physics that deals with the universe, is facing a bit of a crisis right now. Four crises, actually. Let’s take a look at the biggest problems with ...

In celebration of 35 years spent in orbit around Earth, the Hubble team has released a set of four new images showing the ...
