Is making dark matter possible?

Several scientific groups, including one at CERN’s Large Hadron Collider, are currently working to generate dark matter particles for study in the lab. Other scientists think the effects of dark matter could be explained by fundamentally modifying our theories of gravity.

Is dark matter strong?

There is no evidence that dark matter is capable of such a wide variety of interactions, since it seems to only interact through gravity (and possibly through some means no stronger than the weak interaction, although until dark matter is better understood, this is only speculation).

Can dark matter be touched?

When we look out into the universe, we don’t know what we’re looking at for the most part. In fact, we can’t even see most of what we’re looking at – that’s because the majority of the universe is made up of mysterious, practically invisible dark matter.

What dark matter Cannot be?

Dark matter is material that cannot be seen directly. We know that dark matter exists because of the effect it has on objects that we can observe directly. Scientists study dark matter by looking at the effects it has on visible objects.

Can dark matter destroy the universe?

This positron signature could have a variety of causes, but a prime candidate is dark matter, the intangible stuff thought to make up about 98 percent of all matter in the universe. When two dark matter particles collide they can sometimes destroy each other and release a burst of energy that includes positrons.

What would dark matter do to a human?

But scientists have now proposed a surprising new sensor: human flesh. The idea boils down to this: If a certain type of dark matter particle existed, it would occasionally kill people, passing through them like a bullet.

Are we made of stardust?

Planetary scientist and stardust expert Dr Ashley King explains. ‘It is totally 100% true: nearly all the elements in the human body were made in a star and many have come through several supernovas. ‘

How long till the universe ends?

Thanks to the expansion caused by dark energy, within a couple of trillion years, all but the closest galaxies will be too far away to see. Then, perhaps 100 trillion years later, star formation will cease, as dense stellar remnants like white dwarfs and black holes lock up any remaining material.
