The universe is getting hotter, but scientists say that the rate of that expansion has slowed down, according to a new study.
The latest work in the search for dark energy, which accounts for the accelerating expansion of the universe, has been published in Nature Physics.
The researchers examined the physics of the cosmic microwave background (CMB) that was emitted when the universe was just 4.6 billion years old, which is the age when the cosmic radiation that is produced by exploding stars is absorbed by the fabric of the cosmos.
The CMB has been found to contain the remnants of gamma-ray bursts from the early universe, which could explain the appearance of dark energy and the accelerating increase in temperature.
“It’s really exciting because it really suggests that the CMB is not an anomaly,” said lead author Peter Lautner, an astrophysicist at the University of Oxford in the UK.
“It is something that we could actually look at in the future.”
The CGB was discovered when a team of scientists, including Lautners colleagues from the University, the University at Buffalo in New York, and the University College London, discovered an extraordinary explosion of starlight from a nearby supernova called SN1987A.
The explosion produced energy that led to a massive explosion in the cosmic microwaves.
The explosion produced radiation that was so high in energy it is thought to have entered the universe before it even exploded, but astronomers are still trying to determine whether that energy was generated by dark energy or simply the remnants from an explosion of other stars.
The study found that the temperature of the CGB has been steadily increasing since SN1987B, and that the average temperature of that radiation over the past two years has decreased by about 0.3 degrees Celsius.
The research team compared the data from the CIB to measurements of the temperature changes at the start of the Universe’s early history and found that this rate of temperature change had slowed down.
“These changes are really striking,” said Lauters co-author, astrophysicists Chris Davenport and Mark Sussman.
“We have had a very gradual temperature increase over the last 150 years, and now it’s dropping.
This is something we have not seen before.”
The team also calculated that the universe has cooled by about 20 percent since SN87B.
Lautner and his colleagues believe that the rapid rate of cooling may be related to the formation of stars, which formed during the early years of the big bang.
Theories on how stars form, the size of stars and their mass are still in their infancy.
They have yet to be explored fully.
In the study, Lauter and his co-authors say they have now identified the most likely explanation for the cooling in the Cgb: stars are being stripped of their gravity by the gravitational influence of the matter surrounding them.
“Theoretically, we should expect stars to cool by about a factor of two in the case of a black hole collapsing into a white dwarf,” Lautsner said.
“Theoretical models have suggested that this is likely to happen.
We’ve found that stars are losing about a third of their mass in the process, and they’re doing so very slowly.
We’re now looking at the processes that are contributing to this.”
This is a very interesting study that we’ve just published in a peer-reviewed journal, and we hope it will give some answers to questions that have been in the literature for a long time.
But we are still working to see if it is possible to see how fast this is happening, and how long it’s going to take.
“The study also finds that the cooling rate is slowing down in the distant past, around 4.5 billion years ago.
But the rate is still accelerating.”
We know that the expansion is accelerating, but this has not been seen before,” Laxner said, “and it is one of the key mysteries of the expansion.
