Summary touches City Hall, stock markets and outer space

Mayor John Tory warned of a “real chance” of a labour disruption involving indoor and outdoor workers in a letter to city councillors Thursday. He says that the “climate at the negotiations table and the union’s declaration that they will accept no concessions indicate that there is a real chance we will have a labour disruption”. .The Toronto stock market sank nearly 100 points Thursday, the fifth day of large losses. Traders were saying things like:  “Everyone is looking at negative rates in Europe and Japan, and trying to figure out what that means to the banking system.” And scientists for the first time have detected gravitational waves, ripples in space and time hypothesised by Albert Einstein a century ago, in a landmark discovery announced on Thursday that opens a new window for studying the cosmos. The waves were unleashed by the collision of the black holes, one of them 29 times the mass of the sun and the other 36 times the solar mass, located 1.3 billion light years from Earth, the researchers said. It’s not clear from news reports just how, if at all, this knowledge might be applied to human life.
