Perhaps the first magnetic fields of the universe were much weaker than we first imagined – and were almost equivalent to the power of magnetic activity inside The human brainAccording to a new study.
Researchers used hundreds of thousands of computer simulations to examine the remains of these old magnetic fields, which are still present within “Cosmic Web“Billions of years.
But in the new study, it was published on August 13 in the magazine Physical review messagesThe researchers revealed that these primitive fields may have been weaker than they had previously imagined. Using comprehensive computer simulation operations, the team restricted the upper limit of the magnetic power of these fields and found that they are likely to be at 0.000000000022 GASS, which is billions of times weaker than the standard refrigerator magnet (about 100 gaos).
Such magnetic fields “comparable to the resulting magnetic by [the electrical activity of] The researchers wrote in the human brain ” statement.
Despite its weakness, the remains of these magnetic fields are still present within the cosmic network between galaxies – a mysterious, sprawling structure that permeates the entire universe – and this was the key to detecting new results.

The cosmic web is an expanded network of ghost threads Connect all galaxies in the universe Like a giant 3D spider network. There is still a lot that we do not know about the cosmic web, including what is already made. However, in recent years, scientists have begun to properly photograph this giant structure and have them She started appointing her in detail.
One of the largest puzzles around the cosmic web network is the reason that it has its magnetic fields. This is particularly confusing in space areas between galaxies, where the web is isolated inside large areas of nothingness.
“Our assumption was that this [magnetism] It can be a legacy of events that occur in the cosmic era during the birth of the universe. ”The author of the leading study Mac PavsvichPhD candidate at the International School of Advanced Studies (SISSA) in Tars, Italy, and co -author Matteo a lotThe astronomical physicist in Cisa said in the statement. “This is what we sought to make sure of our work.”
Their team believes that the oldest primitive magnetic fields could have been discovered in the initial inflation of the universe and that they are later intertwined with the cosmic network, as they grew in the dilated areas between galaxies.
In the study, the researchers used approximately 250,000 computer simulations, based on the monitoring data of the cosmic network, to reflect this supposed chain of events, allowing them to set “strict limits on the intensity of the magnetic fields that were formed in the very early moments of the universe.”
These results are still theoretical as there is currently no way to monitor the primitive magnetic fields. However, the researchers claim that the results are in line with the recent related results Cosmic microwave background (Cmb), which is the radiation residue of the big explosion, although it is not clear the specific results they refer to.
The study team also notes that the ongoing notes of the cosmic network with the JMST telescope can allow them to create more powerful simulations to increase their future hypothesis test.
