Dark matter may be older than the Big Bang
Dark matter, which researchers believe make up about 80% of the universe's mass, is one of the most elusive mysteries in modern physics. What exactly it is and how it came to be is a mystery, but a new Johns Hopkins University study now suggests that dark matter may have existed before the Big Bang.




The study, published August 7 in Physical Review Letters, presents a new idea of how dark matter was born and how to identify it with astronomical observations.

"The study revealed a new connection between particle physics and astronomy. If dark matter consists of new particles that were born before the Big Bang, they affect the way galaxies are distributed in the sky in a unique way. This connection may be used to reveal their identity and make conclusions about the times before the Big Bang too," says Tommi Tenkanen, a postdoctoral fellow in Physics and Astronomy at the Johns Hopkins University and the study's author.

While not much is known about its origins, astronomers have shown that dark matter plays a crucial role in the formation of galaxies and galaxy clusters. Though not directly observable, scientists know dark matter exists by its gravitation effects on how visible matter moves and is distributed in space.

For a long time, researchers believed that dark matter must be a leftover substance from the Big Bang. Researchers have long sought this kind of dark matter, but so far all experimental searches have been unsuccessful.

"If dark matter were truly a remnant of the Big Bang, then in many cases researchers should have seen a direct signal of dark matter in different particle physics experiments already," says Tenkanen.

Using a new, simple mathematical framework, the study shows that dark matter may have been produced before the Big Bang during an era known as the cosmic inflation when space was expanding very rapidly. The rapid expansion is believed to lead to copious production of certain types of particles called scalars. So far, only one scalar particle has been discovered, the famous Higgs boson.

"We do not know what dark matter is, but if it has anything to do with any scalar particles, it may be older than the Big Bang. With the proposed mathematical scenario, we don't have to assume new types of interactions between visible and dark matter beyond gravity, which we already know is there," explains Tenkanen.

Not buying it but who knows? I guess his guess is as good as any guess. Thanks for posting.

So the Niblonians were pooping before the Universe was born?

Just a regular dumb arse here, but it sounds like they are all guessing.

I think we're all dumb asses about this subject friend.

This part was what led me to post the article.....

The new study also suggests a way to test the origin of dark matter by observing the signatures dark matter leaves on the distribution of matter in the universe.

"While this type of dark matter is too elusive to be found in particle experiments, it can reveal its presence in astronomical observations. We will soon learn more about the origin of dark matter when the Euclid satellite is launched in 2022. It's going to be very exciting to see what it will reveal about dark matter and if its findings can be used to peek into the times before the Big Bang."

Sometimes I wonder if they just make shite up since very few could actually even pretend to fact check them and nothing can ever be tested

re: Dark matter may be older than the Big Bang
I thought this was a pretty common theory that Dark matter contracted imploded on itself creating the universe. almost like a reverse supernova with the pulsar being regular matter.

re: Dark matter may be older than the Big Bang
Until we can more objectively quantify Dark Matter most any theory involving it is going to mostly be conjecture.

We are, to the best of of my knowledge, not even able to accurately measure it at the moment. Most of science we can directly observe. We can record temperatures for Climate Change (yes, yes, I know it isn't real and if it is real its isn't our fault, and if it is our fault it is actually the fault of the News Media). We can observe evolution through the fossil record and from ongoing evolution among species.

With Dark Matter the best and brightest people on the planet are basically throwing their hands in the air and saying "hell if I know". Still, science marches on. It took us a while to disprove the Heliocentric theory. It will probably take us a while to fully understand this.

You mean "disprove the geocentric theory" and instead embrace the heliocentric orbit. Or maybe I am just confused about what you are saying. I can be an airhead sometimes.

What we can measure is its gravitational effect. We can also observe that directly. Gravitational lensing and the movement of stars in galaxies proves the existence of dark matter.

Its existence is beyond debate. Its substance remains unknown. As with gravity, we are very familiar with its effects while still knowing nothing about what causes it.

You are correct sir. I meant prove the Heliocentric, not disprove. I am not good without my caffeine.
