What is dark matter and dark energy?
Dark matter makes up most of the mass of galaxies and galaxy clusters, and is responsible for the way galaxies are organized on grand scales. Dark energy, meanwhile, is the name we give the mysterious influence driving the accelerated expansion of the universe.
Can dark matter be used as fuel?
Current rocket technology can not send the spaceship very far, because the amount of the chemical fuel it can take is limited. We try to use dark matter (DM) as fuel to solve this problem.
Can dark energy turn into dark matter?
Dark Matter is the missing matter that explains the flat rotation curves in galaxies. Dark Energy is the unknown energy that explains the accelerated expansion of the universe. The fact that they do two different things suggests they cannot be converted into each other.
How does a dark matter detector work?
Liquid xenon WIMP detectors Each uses a vessel that can hold the liquid xenon. Arrays of photomultiplier tubes, or PMTs, sit above and below the xenon target, where they create an electrical field. Scientists install the detector deep underground to reduce the noise of cosmic rays by a factor of about 10 million.
How much does dark matter cost?
Discovering just one dozen dark particles would be enough to throw all of modern physics for a loop. Considering the LUX experiment cost about $10 million to build, that puts the effective price of dark matter at, oh, about one million trillion trillion dollars per ounce.
Where is dark matter located?
The answer is gravity. Astronomers indirectly detect dark matter through its gravitational influences on stars and galaxies. Wherever normal matter resides, dark matter can be found lurking unseen by its side.
Will dark matter let us control gravity?
The even distribution means that dark energy does not have any local gravitational effects, but rather a global effect on the universe as a whole. This leads to a repulsive force, which tends to accelerate the expansion of the universe.
What does dark matter look like?
But because it doesn’t interact with light, it has never been observed and is difficult to study. Using a simulation of the universe, Harvard researchers found that dark matter seems to ahve a universal property: It forms halos.
Can I buy dark matter?
Some cryptocurrencies, like Dark Matter, can only be purchased with another cryptocurrency on decentralized exchanges. To buy Dark Matter, you’ll need to first purchase Ethereum (ETH) and then use ETH to buy Dark Matter. And to do that, you need what’s called a self-custody wallet.

What does dark matter do to humans?
The nuclear forces that hold your nuclei and protons together would vanish; the electromagnetic forces that caused atoms and molecules to stay together (and light to interact with you) would disappear; your cells and organs and entire body would cease to hold together.
What is the difference between dark matter and dark energy?
Dark matter makes up most of the mass of galaxies and galaxy clusters, and is responsible for the way galaxies are organized on grand scales. Dark energy, meanwhile, is the name we give the mysterious influence driving the accelerated expansion of the universe.
What is dark matter made of?
The blue shows a map of the total mass concentration (mostly dark matter). However, at this point, there are still a few dark matter possibilities that are viable. Baryonic matter could still make up the dark matter if it were all tied up in brown dwarfs or in small, dense chunks of heavy elements.
Is dark matter baryonic?
These possibilities are known as massive compact halo objects, or ” MACHOs “. But the most common view is that dark matter is not baryonic at all, but that it is made up of other, more exotic particles like axions or WIMPS (Weakly Interacting Massive Particles).
Is dark matter antimatter?
Third, dark matter is not antimatter, because we do not see the unique gamma rays that are produced when antimatter annihilates with matter. Finally, we can rule out large galaxy-sized black holes on the basis of how many gravitational lenses we see.
