Improved Hubble yardstick gives fresh evidence for new physics in the universe

"Explaining a Vexing Discrepancy

Riess outlined a few possible explanations for the mismatch, all related to the 95 percent of the universe that is shrouded in darkness. One possibility is that dark energy, already known to be accelerating the cosmos, may be shoving galaxies away from each other with even greater - or growing - strength. This means that the acceleration itself might not have a constant value in the universe but changes over time in the universe. Riess shared a Nobel Prize for the 1998 discovery of the accelerating universe.

Another idea is that the universe contains a new subatomic particle that travels close to the speed of light. Such speedy particles are collectively called "dark radiation" and include previously known particles like neutrinos, which are created in nuclear reactions and radioactive decays. Unlike a normal neutrino, which interacts by a subatomic force, this new particle would be affected only by gravity and is dubbed a "sterile neutrino."

Yet another attractive possibility is that dark matter (an invisible form of matter not made up of protons, neutrons, and electrons) interacts more strongly with normal matter or radiation than previously assumed.

Any of these scenarios would change the contents of the early universe, leading to inconsistencies in theoretical models."

Tämä on jo selvitetty asia.

Ei tarvita massiivisia voimia työntämään galaksijoukkoja pois päin toisistansa.

Valo venyy eli yleisesti punasiirtyy koska laajenevan valon aallot vuorovaikuttavat toistensa kanssa uusi valo vähän vanhaa valoa nopeampana, kiihdyttää vanhan valon vauhtia, jolloin se venyy eli yleisesti punasiirtyy itse avaruudessa liikkuessaan.
