What do we not know about dark matter?
We can learn that dark matter behaves as though it has mass, but doesn’t emit or absorb light; it can only bend it through its gravitational effects on spacetime.
It’s not actually dark; it’s rather transparent, as it doesn’t have a color at all..
What does dark matter include?
Dark matter can refer to any substance which interacts predominantly via gravity with visible matter (e.g., stars and planets). Hence in principle it need not be composed of a new type of fundamental particle but could, at least in part, be made up of standard baryonic matter, such as protons or neutrons.
Where is all the dark matter?
The first variety is about 4.5 percent of the universe and is made of the familiar baryons (i.e., protons, neutrons, and atomic nuclei), which also make up the luminous stars and galaxies. Most of this baryonic dark matter is expected to exist in the form of gas in and between the galaxies.
What is currently known about dark matter?
More is unknown than is known. We know how much dark energy there is because we know how it affects the universe’s expansion. … Dark matter makes up about 27%. The rest – everything on Earth, everything ever observed with all of our instruments, all normal matter – adds up to less than 5% of the universe.
Is dark matter everywhere?
Dark matter is EVERYWHERE Planets, stars, asteroids, galaxies – the things that we can actually see – constitute less than 5% of the total universe. … Dark matter is the name we give to all the mass in the universe that remains invisible, and there’s a whole lot of it.
How much does dark matter cost?
It would be about 1 million trillion trillion dollars per ounce. The LUX experiment costed 10 million dollars to build.
Is dark matter harmful?
But more-massive pieces of dark matter known as macroscopic dark matter, or macros, could lurk in the cosmos. In theory, macros could directly interact with physical objects such as human bodies, causing “significant damage,” according to the new study titled “Death by Dark Matter.”
Is Dark Matter solid?
For a perfect fluid negative presure leads to instabilities that are most severe on the shortest scales. However, if instead the dark matter is a solid, with an elastic resistance to pure shear deformations, an equation of state with negative presure can avoid these short wavelength instabilities.
Can you create dark matter?
One leading hypothesis is that dark matter consists of exotic particles that don’t interact with normal matter or light but that still exert a gravitational pull. Several scientific groups, including one at CERN’s Large Hadron Collider, are currently working to generate dark matter particles for study in the lab.
Why is dark matter so expensive?
Due to its explosive nature (it annihilates when in contact with normal matter) and energy-intensive production, the cost of making antimatter is astronomical. CERN produces about 1×10^15 antiprotons every year, but that only amounts to 1.67 nanograms.
What can dark matter do?
Scientists believe that dark matter may account for the unexplained motions of stars within galaxies. Computers play an important role in the search for dark matter data. They allow scientists to create models which predict galaxy behavior. Satellites are also being used to gather dark matter data.
How many galaxies are there?
The best estimate from a 1999 study set that number at about 125 billion galaxies, and a 2013 study indicated that there are 225 billion galaxies in the observable universe. In 2016, that number was upped to 2 trillion, in large part because a new analysis included all the tiny, fluffy galaxies in the early universe.
Can you see dark matter?
Although we cannot see dark matter and we have not yet detected it in a lab, its presence is made known through gravitational effects. Based on theoretical models of the universe, dark matter accounts for nearly five times as much of the universe as does regular matter.
Is Dark Matter heavy?
Scientists have calculated the mass range for Dark Matter — and it’s tighter than the science world thought. Scientists have calculated the mass range for Dark Matter — and it’s tighter than the science world thought.
Can Dark Matter give you superpowers?
In the game series Mass Effect, dark matter is manifested in the form of a substance called “Element Zero”, which is informally referred to as “eezo”. … In DC’s Flash, all the things are about the Dark Matter which gives human superpowers.
Are black holes dark matter?
The international team find that rather than the conventional formation scenarios involving ‘normal’ matter, supermassive black holes could instead form directly from dark matter in high density regions in the centres of galaxies. The result has key implications for cosmology in the early Universe.
How many types of dark matter are there?
Dark Matter candidates are either baryonic or non-baryonic, or a mixture of both. The non-baryonic forms are usually subdivided into two classes – Hot Dark Matter (HDM) and Cold Dark Matter (CDM).
Is there dark matter in humans?
It has been estimated that in material from humans, between 40 and 90% of viral sequences are from Dark Matter. Human blood contains over three thousand different DNA sequences which cannot yet be identified.
Can matter be created?
Water is composed of two hydrogen atoms bonded to an oxygen atom. Photograph by OJO Images Ltd. From port-a-potties to supernovas, matter makes up everything visible in the known universe. Because matter is never created or destroyed, it cycles through our world.
How much is a gram of dark matter?
1 gram of dark matter is worth $65.5 trillion.
