Why is neutrino called a ghost particle?<\/p>\n<p><strong>Ans<\/strong>. Neutrinos earned the nickname &#8220;ghost particles&#8221; because they can pass through vast amounts of matter undetected, interact very weakly with other particles, and are extremely hard to observe.<\/p>\n<p><strong>Q2<\/strong>. Are there 3 types of neutrinos?<\/p>\n<p><strong>Ans<\/strong>. Scientists named the three types of neutrinos they have discovered so far for the other matter particle they interact with: the electron neutrino, muon neutrino, and tau neutrino<\/p>\n<p><strong>Q3<\/strong>. What is the smallest particle known to man?<\/p>\n<p><strong>Ans<\/strong>. The smallest particle known to man is the quark.\u00a0<\/p>\n<p><strong>Source<\/strong>:<a href=\"https:\/\/indianexpress.com\/article\/world\/china-installs-deep-sea-detector-mysterious-ghost-particles-9823911\/\" target=\"_blank\" rel=\"nofollow noopener\"> IE<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Neutrinos are nearly massless, electrically neutral subatomic particles that interact extremely weakly with matter.<\/p>\n","protected":false},"author":5,"featured_media":3275,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-3274","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/3274","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=3274"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/3274\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/3275"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=3274"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=3274"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=3274"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
