Theory?<\/b><\/h2>\n<ul>\n<li style=\"text-align: justify;\"><span style=\"font-weight: 400;\">String theory is a scientific framework that<\/span><b> attempts to explain how the universe works at its most fundamental level.<\/b><\/li>\n<li style=\"text-align: justify;\"><span style=\"font-weight: 400;\">According to this theory, the <\/span><b>smallest building blocks of matter<\/b><span style=\"font-weight: 400;\"> are <\/span><b>not point-like particles but tiny, one-dimensional objects called strings.<\/b><\/li>\n<li style=\"text-align: justify;\"><b>These strings<\/b><span style=\"font-weight: 400;\"> can <\/span><b>vibrate in different ways<\/b><span style=\"font-weight: 400;\">, with <\/span><b>each pattern of vibration corresponding to a different particle.\u00a0<\/b><\/li>\n<li style=\"text-align: justify;\"><span style=\"font-weight: 400;\">In this way, string theory offers a <\/span><b>possible common framework for understanding<\/b><span style=\"font-weight: 400;\"> the <\/span><b>different particles and forces <\/b><span style=\"font-weight: 400;\">found in nature.\u00a0<\/span><\/li>\n<li style=\"text-align: justify;\"><span style=\"font-weight: 400;\">One of its <\/span><b>major goals<\/b><span style=\"font-weight: 400;\"> is to <\/span><b>bring gravity into the framework of quantum physics<\/b><span style=\"font-weight: 400;\">, which describes the behaviour of matter and energy at extremely small scales.\u00a0<\/span><\/li>\n<li style=\"text-align: justify;\"><b>Scientists <\/b><span style=\"font-weight: 400;\">have<\/span><b> long struggled to reconcile the two<\/b><span style=\"font-weight: 400;\">, <\/span><b>particularly in extreme environments<\/b><span style=\"font-weight: 400;\"> such as <\/span><b><a href=\"https:\/\/vajiramandravi.com\/upsc-exam\/black-hole\/\" target=\"_blank\">black holes<\/a>,<\/b><span style=\"font-weight: 400;\"> where gravity and quantum effects become
