The Teachama Cosmology Telescope (Act) in Chile has spent nearly two decades studying how the universe began, how it got to its current state. The observatory is decommissioned In 2022, but the last batch of data is still sending shockwaves through the Cosmological Community.

A recent study published in Journal of Cosmology and Phyroparigical Physics This data was used to test about 30 “extended” models of evolution – alternative universes to the standard model of cosmology. These alternatives attempt to explain some cosmological phenomena that the standard model cannot, such as Hubble Tensiona distinction between different scales of the universe’s expansion.

The researchers ordered each tall model they tested. Along with another JCAP-Published LEARN That used the last ACT data to confirm the Hubble tension, the findings deepening this cosmopical mystery, leaving experts with more questions about the universe.

“We analyzed them completely independently,” said Erminia Calabreese, a Cardiff University Cosmologist and Co-author of the study that tested a statement. “We are not trying to knock it, just to study it. And the result is clear: the new observations, of new scales for this type of exercise. There are people who prompt this exercise.

A deepening cosmic mystery

There are two main ways to measure the expansion of the universe, also known as the Hubble Constant. One method involves looking at radiation leftover from the Big Bang (the Microwave Background), and the other looks at galaxies and supernovae in the local universe.

According to the standard model of cosmology, both methods should produce the same value. The problem is, they don’t. This, in essence, is the hubble tension.

Researchers have spent years trying to explain this difference, and they have a lot Interesting hypotheses. Some have found The evidence to suggest the hubble tension simply does not exist. The latest action data strengthens the case for this cosmological conundrum but leads experts to be unable to resolve it.

More questions, but a clearer path to answers

So, “how big?” you ask. Well, for one thing, confirming the Hubble tension with observations in the works means we can be pretty sure this problem is real.

The telescope probes the microwave background with unprecedented precision, producing polarization maps that complement the temperature maps. iso by the European Space Agency Spacecraft. By comparison, action maps-hagding In the third JCAP study – there is a much higher resolution than POLOCK’S. Much of this owes to the fact that the main mirror of the ACT Movement is much larger than the POLOCK, with a diameter of about 20 feet (6 meters).

“When we compare (the maps), it’s a little bit like cleaning your glasses,” Calebreese said. As such, the ACT data fill many gaps in our understanding of the CMB.

“Our new results show that the Hubble is always written from the ACT CMB Data of the CMB – not only from the temperature data using the Hubble tension, which confirms the statement.

The observations of Act Calabese and his colleagues also allow to rule out many preferred models that seek to explain the Hubble tension. While this opens up various possibilities, it provides a clear path forward. If these models are dead ends, it’s time to stop chasing them and look for answers elsewhere.

The Hubble Motion may be overblown, but its final data release marks a new beginning for cosmologists working to resolve the Hubble tension. Experts will continue to use the data for years to come, INCHING Their Way Closer to a Better Understanding of Our Growing Universe.
