Scientists have found evidence of an extremely early phase of the Big Crunch.
They’ve found that the planet was once hot, with a liquid core that cooled off rapidly and then cooled again as it cooled.
“We know it was hot, because the stars were still young, so there was this tremendous pressure on the core,” says lead researcher Timo Häkkinen from the Max Planck Institute for Solar System Research in Göttingen, Germany.
But it was hotter than today, he says, because we know that the stars would have cooled and contracted with time.
It’s an amazing finding, says Häkinen.
The Big Crunch The discovery of the core is important for understanding how the early universe cooled and collapsed, and for the search for the Big Rip.
It was a period when the universe was so small that all the energy of the stars could have been stored in a single core.
“This means that the big bang happened a bit before all the stars,” says Höckem.
The early universe, with its relatively young core, contained the same amount of matter and energy as the modern universe, which is around 8.8 billion years old.
This is why it was so hard to form planets and stars from the matter in the early Universe.
“There’s no way of knowing that,” says Michael Witter, a physicist at the University of New South Wales in Sydney, Australia.
So, scientists had to look for evidence that the early stars cooled so quickly, they got stuck.
“It was the case that the hot cores of young stars were in a much cooler state, because of their greater density,” he says.
This meant that stars formed from the collapse of stars that were already very hot, and that they collapsed as they cooled down.
But in the core, the hot core was cooled down by the liquid helium that came from the hot star.
It cooled off so fast that it cooled the solid outer shell of the planet.
The core could then cool off more slowly.
“The core was not a stable state.
It could collapse again,” says Witter.
This happened very quickly.
“All of the young stars are now older than the core and it is a new era in the history of the universe.”
The core is in a new place When the scientists looked for evidence of the early collapse of the big core, they found evidence for a cooling of the interior of the planets.
That’s because the outer shells of stars are so hot that they heat up very quickly, and the liquid inside of them cools quickly, too.
But this is because the liquid in the star core is much cooler than the liquid that is in the planets’ outer shells.
The stars that are cooler, like our Sun, are much cooler.
When the outer shell cools, it cools the star that is inside, too, so the outer outer shell is also cooler.
That means the outer stars are in a different state of coldness, because they are hotter than the star inside.
“So we have a little bit of a puzzle,” says Timo.
“How do these two systems get to be like this?
And we know this in terms of the outer layers of the star, but not in terms the core.”
The new evidence shows that the young planets were in very different states from the core.
The star that was cool and still hot was very hot in the interior, but cooled down much faster.
“That’s very interesting,” says Mark Weisburger, a cosmologist at the National Center for Atmospheric Research in Boulder, Colorado.
“If you were a child in the 1990s and you saw a telescope, you’d say, ‘I wonder what happened in those years.’
Now we know how this happens.”
The Big Bang was a moment of intense growth of the Universe When the stars formed, the Universe was just one part of the Large Hadron Collider at CERN in Geneva, Switzerland.
At the end of the 20th century, scientists were looking for evidence for the existence of dark energy, the force that is thought to be the missing glue that keeps everything together.
When dark energy was discovered in the late 1980s, scientists realized that it was not part of our universe and it wasn’t real.
It had a different name: the Higgs boson.
“Dark energy is a very strong force,” says Weisbeger.
“And the Higgessons are a lot like that force.”
When dark matter and dark energy were first detected, they were considered to be incompatible.
But now we know they are not incompatible, because dark energy is in fact a kind of particle.
“At the end, dark energy and dark matter are in the same category,” says Steve Brusatte, a theorist at the California Institute of Technology in Pasadena, who was not involved in this work.
“They are both particles.”
