How can you detect dark matter?
We can detect the dark matter through gravitational lensing, which detects shifts in light produced by distant celestial objects [5]. The bright spots outside the colored areas are stars and galaxies that are not part of the Bullet Cluster (Credit: X-ray: NASA/CXC/CfA/ M.
Has a dark matter particle been found?
Dark matter, according to mathematical models, makes up three-quarters of all the matter in the universe. But it’s never been seen or fully explained. Now, an international team of scientists says it has found new evidence that perhaps dark matter doesn’t really exist after all.
Is it possible to create dark matter?
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.
Can we detect dark energy?
Dark energy isn’t just dark — it’s nigh invisible. Hypothesized by physicists to drive the accelerating expansion of the universe, dark energy has never been directly observed or measured. Instead, scientists can only make inferences about it from its effects on the space and matter we can see.

How are scientists trying to find dark matter?
Some experiments are using telescopes in space and on the ground to look for indirect signals of dark-matter particles as they collide and break themselves out in space. Others still are chasing these elusive particles directly by searching for the kicks, or “shakes,” they give to atomic nuclei in underground detectors.
Is there a dark-matter equivalent of the photon?
These dark-sector particles could include a dark-matter equivalent of the photon, the dark photon, which would interact with the other dark-sector particles as well as the known particles, and long-lived particles, which are also predicted by SUSY models.
What is a particle accelerator and how does it work?
What is a particle accelerator? A particle accelerator is a machine that accelerates elementary particles, such as electrons or protons, to very high energies. On a basic level, particle accelerators produce beams of charged particles that can be used for a variety of research purposes.
How many particle accelerators are there in the world?
Today, there are more than 30,000 particle accelerators in operation around the world. What is a particle accelerator? A particle accelerator is a machine that accelerates elementary particles, such as electrons or protons, to very high energies.
