Tabetha Boyajian: The most mysterious star in the universe Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing celestial object, a colleague suggested something unusual: Could it be an alien-built megastructure? Such an extraordinary idea would require extraordinary evidence. In this talk, Boyajian gives us a look at how scientists search for and test hypotheses when faced with the unknown.

Allan Adams: Što znači otkriće gravitacijskih valova? Prije više od milijardu godina dvije crne rupe u dalekoj galaksiji zaplele su se i nezaustavljivo približavale dok se nisu sudarile. " Sva ta energija bila je izbačena u spoj vremena i prostora", kaže teoretski fizičar Allan Adams, "čineći eksplozije uzburkanih gravitacijskih valova u svemiru." Prije otprilike 25 godina grupa znanstvenika napravila je ogroman laserski detektor nazvan LIGO u potrazi za takvim tipom valova za koje se pretpostavljalo da postoje, ali nisu nikad uočeni. U nadahnjujućem govoru Adams objašnjava što se dogodilo u rujnu 2015. kada je LIGO detektirao nevjerojatno malu anomaliju koja je dovela do jednog od najuzbudljivijih otkrića u povijesti fizike.
