There was no gravitational waves from the universe’s childhood that scientists discovered last year – without the dust. Analyses of satellite will be the nail in the coffin of “the most important discovery in decades.”
It was in March last year by researchers at the Harvard-Smithsonian Center for Astrophysics in the US beating the drums and announced that they had discovered the gravitational waves that are assumed to have been spread in the universe immediately after the Big Bang, the Big Bang that created the universe 13.8 billion years ago.
The discovery was seen as the first direct evidence of cosmic inflation, that is, the enormous expansion that scientists believe that the universe underwent a very early stage after the Big Bang. Cosmologists the world became lyrical and the find was described as the largest in cosmology for decades.
Soon after, however, doubts whether it really was these waves that scientists had caught up with their instruments. In September, it was clear that most of the waves was most likely a result of the “dust” found in space throughout our galaxy. But really sure they were not.
The European Space Agency has now made a new analysis, this time with the help of, among other things, the Planck satellite, and the results confirm previous studies: Gravitational waves were in fact nothing more than common space dust.
