After counting all the normal, luminous matter in the obvious places of the universe – galaxies, clusters of galaxies and the intergalactic medium – about half of it is still missing. So not only is 85 percent of the matter in the universe made up of an unknown, invisible substance dubbed “dark matter”, we can’t even find all the small amount of normal matter that should be there.

This is known as the “missing baryons” problem. Baryons are particles that emit or absorb light, like protons, neutrons or electrons, which make up the matter we see around us. The baryons unaccounted for are thought to be hidden in filamentary structures permeating the entire universe, also known as “the cosmic web”.

They may be something else entirely.

When LIGO and Virgo detected the echoes that likely came from a collision between a black hole and a neutron star, dozens of physicists began a hunt for the signal’s electromagnetic counterpart.

A WORMHOLE could allow space travel to the most distant regions of the universe in an instant and now a recent scientific paper has outlined a way to actually build on these anomalies of physics.

What about what happens when two black holes collide?

Goddard Scientist Roopesh Ojha sheds light on the supermassive and stellar mass black holes within our galaxy. Scientists believe one supermassive black hole exists at the center of every galaxy and that many, many more of their much smaller siblings, the stellar mass black holes, surround it.

Some of the most distant rocks in our solar system act in a way that suggests there’s some massive object out there we haven’t been able to see. A planet? Maybe. But why not a small black hole?

That’s a scenario a pair of scientists describe in a new paper. Of course, they recognize that a planet is more likely than an ancient black hole unlike any we’ve directly observed. But they simply want astronomers to think creatively while hunting for whatever this hypothetical object, often called Planet Nine, might be.

This alternate explanation for ‘Planet Nine,’ proposed by scientists in a new paper, poses some fundamental questions like: Should we visit it?

Are black holes bald or hairy? It all depends on the details of a fleeting gravitational wave.

They were spotted in the act of merging in a galaxy a billion light years away.
