Dark matter exerts ‘gravitational force’, meaning that it draws other matter towards it. For this reason, most experts think that dark matter is abundant in the universe and that it has had a strong influence on its structure and evolut… Dark matter could be white dwarfs, the remnants of cores of dead small- to medium-size stars. So what makes up the rest? Dark matter is material that cannot be seen on objects that we can observe directly.Scientists study dark matter by looking at the effects it has on Scientists believe that dark matter may account for the unexplained motions of stars within galaxies. 18% of the matter based on mass in the universe is visible to us and the other 82% is dark matter that we can’t see. Here’s an excerpt from the episode: Jake: Bill, focus right now. reflect, or emit light, so they cannot be detected by observing
If you look at the sky through a telescope and there appears to be nothing there's actually dark matter.
Some scientists believe that the effects we associate with dark matter are actually caused by gravity.It’s possible that our existing theory of gravity is flawed, and that the effects we attribute to dark matter could simply be a quirk of gravity that we don’t yet understand.So is dark matter a particle or a consequence of gravity? This is some of the strongest evidence of all that dark matter cannot simply be …
We can’t see it, we don’t understand it, but we know it’s out there.Dark matter is really hard to study, because we have no way of seeing it. We know that dark matter exists because of the effect it has the unexplained motions of stars within Scientists have produced many theories about what exactly dark matter
That’s why dark matter is often likened to a giant spider’s web, meshing galaxies in place. the universe will determine if the universe is open (continues
Dark matter is material that cannot be seen directly. In this way, we can identify ‘hotspots’, where higher levels of dark matter may be concentrated.
And so spacecraft have been fitted with advanced detectors to search for signs of this radiation. And other similar facilities exist across the globe, from Canada to Australia.There’s still a whole lot we don’t know when it comes to dark matter, and some mysteries might never be unravelled.

During their recent episode of the VALUE: After Hours Podcast, Taylor, Brewster, and Carlisle discussed dark matter, and why it’s important to investors. We are creating a unified UKRI website that brings together the existing research council, Innovate UK and Research England websites.
