<prompt> Batlisisa se sibolotsoeng ke saense lilemong tse leshome tse fetileng.nan  <response>: Instruction in English: Research a scientific discovery from the past decade. . Response in English: One of the most significant scientific discoveries of the past decade was the direct detection of gravitational waves. Predicted by Einsteins theory of general relativity over a century ago, gravitational waves are ripples in space-time that are caused by massive accelerating objects, such as two black holes or neutron stars spiraling around each other. In September 2015, researchers working on the Advanced Laser Interferometer Gravitational-Wave Observatory LIGO experiment observed a signal from a pair of merging black holes, in what would become the first-ever direct detection of gravitational waves. This discovery opened a new window into the Universe, allowing scientists to study phenomena that were previously inaccessible. Since then, the LIGO collaboration, along with its counterpart Virgo, has continued to observe and detect more gravitational wave signals, bringing a greater understanding of the nature of black holes, neutron stars, and the origin of the Universe. . Response in Sesotho: ngoe ea litšibollo tsa bohlokoa ka ho fetisisa tsa saense lilemong tse leshome tse fetileng e bile ho lemoha ka ho toba maqhubu a khoheli. Ho boleloa esale pele ke khopolo ea Einstein ea kamano e akaretsang lilemong tse lekholo tse fetileng, maqhubu a khoheli ke maqhubu a nako ea sepaka-pakeng a bakoang ke lintho tse khōlō tse potlakisang, tse kang masoba a mabeli a matšo kapa linaleli tsa neutron tse pota-potileng. Ka Loetse 2015, bafuputsi ba sebetsang tekong ea Advanced Laser Interferometer Gravitational-Wave Observatory LIGO ba ile ba bona letsoao le tsoang ho likoti tse kopantsoeng tse ntšo, tseo e neng e tla ba tlhahlobo ea pele e tobileng ea maqhubu a khoheli. Ho sibolloa hona ho ile ha bula fensetere e ncha ea Bokahohle, e leng se ileng sa lumella bo-rasaense hore ba ithute ka liketsahalo tseo pele li neng li sa fihlellehe. Ho tloha ka nako eo, tšebelisano ea LIGO, hammoho le molekane oa eona Virgo, e nile ea tsoela pele ho shebella le ho lemoha matšoao a mangata a matla a khoheli, ho tlisa kutloisiso e khōloanyane ea sebōpeho sa masoba a matšo, linaleli tsa neutron, le tšimoloho ea Bokahohle.
