Hubble trouble or Superbubble? Astronomers need to escape the 'supervoid' to solve cosmology crisisThere are two ways to calculate the Hubble tension; let's call these "observation" and "theory" (though that's really oversimplified). Starting with the theory method, scientists make observations ...
Hubble’s original estimate was 500 km/s/Mpc ... Yet another mysterious character that could account for the discrepancy is “dark radiation.” This theory proposes the existence of a new class of ...
Even Einstein was reluctant to endorse this extension of his theory of general relativity. In 1929 at the Mt. Wilson Observatory in California, Edwin Hubble discovered that galaxies were moving ...

Dark matter, dark energy, the Hubble tension: underpinning these theories is Einstein’s general theory of relativity, which treats space and time as a unified “spacetime” and considers ...
The puzzle of predicting how three gravitationally bound bodies move in space has challenged mathematicians for centuries, and has most recently been popularized in the novel and television show '3 ...
