Best ever map of early universe is double-edged sword for cosmologists

At the beginning of the universe is our last more accurate map, but it also protects the main model of the universe, as it also offers a double edge sword, because new data does not offer the greatest mysteries of cosmology.

The map shows the background of the cosmic microwave (CMB), weak radiation from the initial phases of the universe. First began to be the lightest of 380,000 Big BangBut since the millions of the universe expands it has changed to the microwave of visible spectrum.

Now, new data on the Atacama Cosmology Telescope (Act) provided us clearer image of CMB. Only from the location of the observatory to the location of Chile only in the middle of the sky.

Jo Dunkley He worked in the project at Princeton University, says the component of the universe has improved its age, his age and expansion rates. But it was really a key discovery that nothing is the current main model of the universe LAMBDA-CDM.

The previous data laid down the age of the universe in 13.8 trillion and is expanding – known as the constant hubble – 67 to 68 kilometers away from the ground. Act data is basically confirmed, but it increases accuracy and confidence in these discoveries.

The CMB was mapped for the first time in the 1980s and 90s cosmic background (COBE), followed by NASA Wilkinson Mikrouhin Anisotropy (WMAP) in 2000. In the decade and then more details European Space Agency Planck SpaceCraft From 2009 to 2013. Each mission had more specific maps of CMB, our knowledge of cosmology and early universe to understand our knowledge.

The Law Limit is a land-based telescope, unlike these previous spaces based on the space, that’s why half of the sky is limited. However, the action gives better resolution and sensitivity than these previous maps, but also measures CMB polarization, or also measures the orientation of Oscillate, which explains how to evolve the CMB light over time.

“Seeing the polarization of CMB in better detail, we could have something different. We saw the standard cosmological model,” says Dunkley. “When you look at the universe in a different way, you can’t make sure your original model will still work. We were pretty ready to get something out of that model, some subtlety. But we don’t.”

It may be so relaxing for those who work on Lambda-CDM, but it has not been welcome for all scientists. Colin Hill At Columbia University in New York, he hoped to see some evidence of an unexpected phenomenon, maybe that can help a new type of energy or particle.

“We’ve all done the model (action data) with a standard model. We are looking for a place where different models and cracks will give us something to sink your teeth. And so far, Nature is not given that crack,” says Hills.

Hubble voltage disagreements are the most feasible theories of disagreement, no phenomenon in the action data requires the best we most today. This will return scientists to the drawings to seek another explanation. “Theoretical new measures, including myself, straitjacket has been narrower,” says Hill. “She delves into mystery.”

The law collected the data that forms this new map between 2017 and 2022, but it has shut down. Dunkley said that we will get a high-resolution map for a few years, even a new Chilean telescope will begin this year later. Like the other half of the sky, it is likely that there are only two land locations that would be accommodating the results that would give results: Greenland and Tibet. Dunkey says, unfortunately, Greenland has not yet had the necessary infrastructure for such a project, and Tibet is politically sensitive.

Club Jes At the University of Manchester, the UK, scientists say that scientists have already worked with data, the open version of the Law will turn on a fuzzy activity.

“The community of the entire cosmology can get hands and can all kinds of analysis with its data sets,” says Chlubs. “It’s very exciting and I am pretty sure after follow-up publications will explode.”
