American astrophysicists who announced just months ago what they deemed a breakthrough in confirming how the universe was born now admit they may have got it wrong.
Study finds 'lumpy' universe cannot explain cosmic acceleration
(Phys.org) —Astrophysicists at The University of Texas at Dallas are helping to better define the nature of the cosmos by examining why the universe appears to be expanding at an accelerating pace.
Experts cast doubt on Big Bang bolstering discovery
Astrophysicists are casting doubt on what just recently was deemed a breakthrough in confirming how the universe was born: the observation of gravitational waves that apparently rippled through space right ...
Light from huge explosion 12 billion years ago reaches Earth
Known as a gamma-ray burst, the intense light captured in the night sky resulted from one of the biggest and hottest explosions in the universe, occurring shortly after the Big Bang.Intense light from the ...
Blogger claims BICEP2 team acknowledging possible error in discovery of evidence of gravitational waves
Have cosmologists lost their minds in the multiverse?
The recent BICEP2 observations – of swirls in the polarisation of the cosmic microwave background – have been proclaimed as many things, from evidence of the Big Bang and gravitational waves to something ...
Galactic archaeologists uncover new insights into the formation of the earliest stars and galaxies
A team of Galactic archaeologists has uncovered new insights into the formation of the earliest stars and galaxies by observing the chemical signatures of ancient 'fossil' stars present in the outer and inner halos encircling ...
