ANSWER: Fast Radio Bursts
Explanation:
Scientists have discovered a new way for testing basic principles of Einstein’s theory of general relativity through brief blasts of rare radio signals from space. This new method has been described using radio waves called Fast Radio Bursts which is 10 to 100 times better than previous method using gamma ray bursts. This method is a tribute to Albert Einstein on the 100th anniversary of the first formulation of equivalence principle. Fast Radio Bursts are super-brief blasts of energy lasting just a few milliseconds caused by events beyond the Milky Way.
