Is there a 5th force of nature?
Scientists may have found evidence for a fifth force of nature. Researchers at the Fermi National Accelerator Laboratory, or Fermilab, in Illinois, have found new evidence suggesting that a subatomic particle called a muon is not following the known laws of physics, as The New York Times reports.
What could the 5th force be?
New physics, in the form of a “fifth force”, could be responsible for the odd and unexplained arrangement of dwarf galaxies orbiting the Milky Way and other large galaxies – according to new research done it the UK.
Is dark energy a force?
Dark energy is the name given to the mysterious force that’s causing the rate of expansion of our universe to accelerate over time, rather than to slow down. That’s contrary to what one might expect from a universe that began in a Big Bang. Astronomers in the 20th century learned the universe is expanding.
Is the force dark matter?
Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter.
How many force are there?
Force is the external agent that produces motion. Basically, there are two main types of forces, contact forces, and non-contact forces….SI units for force.
| System | Unit of force |
|---|---|
| SI | Newton (N) |
| Cgs | Dyne |
| British | Slug |
Who is random random?
Random ( Marshall Evan Stone III) is a fictional character and antihero appearing in American comic books published by Marvel Comics. The character was created by writer Peter David for the series X-Factor. He started out as a thorn in the side of X-Factor, but he later became their reluctant ally. The complete origin of Random is unclear.
What is random forest in machine learning?
Random forests or random decision forests are an ensemble learning method for classification, regression and other tasks that operates by constructing a multitude of decision trees at training time and outputting the class that is the mode of the classes (classification) or mean prediction (regression) of the individual trees.
Is random random a hero or villain?

What is the output of a random tree?
For other kinds of random tree, see Random tree. Random forests or random decision forests are an ensemble learning method for classification, regression and other tasks that operates by constructing a multitude of decision trees at training time. For classification tasks, the output of the random forest is the class selected by most trees.
