By Has a WIMP been detected?
So far, scientists have only observed indirect evidence of dark matter. A definitive, direct detection of dark matter particles has yet to be made. There are several theories to account for what that particle might be like. The most favoured one has been the WIMP, or Weakly Interacting Massive Particle.
What are WIMPs and MACHOs?
WIMP is an acronym for weakly interacting massive particle and MACHO is an acronym for massive (astrophysical) compact halo object. WIMPs and MACHOs are two of the most popular DARK MATTER candidates.
Are WIMPs baryons?
WIMPs are assumed to be “nonbaryonic,” or something other than baryons (massive particles such as the proton and neutron that are made up of three quarks), because the amount of baryons in the universe has been determined by measuring the abundance of elements heavier than hydrogen that were created in the first few …
What can WIMPs do?
WIMPs became a favourite candidate for the dark matter in the 1980s. They are typically predicted to be 1–1,000 times heavier than protons and to interact with matter only feebly — through the weak nuclear force, which is responsible for radioactive decay, or something even weaker.
Is WIMP a swear word?
Forget “dork,” “nerd” and “bozo.” The word “wimp,” elevated from the ranks of insult nouns to serious slang, is a four-letter word so mighty that it can undermine political campaigns, cause heated debates between men and women and run in inch-high headline type from coast to coast.
Is a neutrino a WIMP?
Also, in contrast to MACHOs, there are no known stable particles within the Standard Model of particle physics that have all the properties of WIMPs. The particles that have little interaction with normal matter, such as neutrinos, are all very light, and hence would be fast moving, or “hot”.
How are MACHOs detected?
Astronomers have been detecting MACHOs using their gravitational effects on the light from distant objects. In formulating his theory of gravity, Einstein discovered that the gravitational attraction of a massive object can bend the path of a light ray, much like a lens does.
Are WIMPs ruled out?
The most sought after dark matter candidate is the WIMP: the Weakly Interacting Massive Particle. Direct detection experiments have thoroughly ruled out the WIMPs we were hoping for.
How do I stop being a WIMP?
Don’t be a wimp – the art of being assertive
- Communicate confidently. Make sure your tone of voice is not whiny, too soft and that your words are not ‘maybe’ and ‘possibly’. Lose the long pauses and ums from your talk.
- Offer ideas and suggestions.
- Avoid being manipulated.
Is Simp a bad word?
Reception. While the term initially denoted a specific kind of sycophant, upon achieving broad popularity, it began to see use as a general insult.
What does wimp stand for in ICT?
“WIMP” is an interesting bit of computer terminology and lore. It stands for “windows, icons, menus, pointers,” and denotes that the interaction between computer and user is based not on text (e.g., entering commands such as “c://run:d”) but on graphics.
Why is the Milky Way shaped like a disk like a pancake )?
The Milky Way galaxy is made of billions of stars, and gas and dust, all bound together by mutual gravitational attraction, as well as a lot of dark matter. The Solar System resides in one of the Milky Way’s spiral arms, about two-thirds from the center of the Galaxy, in the more flat or “pancake” part of the Galaxy.
