We’ve never been able to directly detect dark matter in any form, but we know it exists through its effects on the universe, especially through the orbital velocities of stars and gravitational lensing of light around “invisible” objects.

Summary: Viruses can convert their DNA from solid to fluid form, which explains how viruses manage to eject DNA into the cells of their victims.

No. That’s the whole point I was making. All of the usual phases of matter other than gas come about because of electromagnetic interactions between the particles. If the particles have no electric charge, they can’t interact electromagnetically and, hence, cannot form solids, liquids, or plasmas.

Scientists study dark matter by looking at the effects it has on visible objects. Scientists believe that dark matter may account for the unexplained motions of stars within galaxies. They allow scientists to create models which predict galaxy behavior. Satellites are also being used to gather dark matterinformation.

Dark matter could be the result of fermions pushed into a warped fifth dimension. This theory builds on an idea first stated in 1999, but is unique in its findings. Dark matter makes up 75 percent of matter but has never been observed yet.

Hence, dark matter may be a direct consequence of the presence of an extra force, generated by the presence of extra-dimensions, which modifies the dynamic law of motion, but does not change the intrinsic properties of the particles, like, for example, the mass (inertia). …

According to a new test of Einstein’s venerable theory, our Universe’s gravity isn’t leaking into other dimensions. In spacetime as we know it, both gravity and light exist. But in large extra dimensions – whatever a fifth, sixth, or seventh dimension is like – gravity might still exist, and light might not.
