Sir, – I hope that Prof Avid Loeb's conjecture is correct and the recent energy bursts coming from deep space turn out to be evidence of a highly advanced alien technology ("Mysterious repeating waves from deep space are detected for second time", World News, January 10th). Hallelujah! Just in the nick of time to sort out the Border! – Yours, etc,
