Environment<\/span><\/span><\/p>\nThese gravitational waves were first proposed 100 years ago by Albert Einstein, as a key prediction of his Theory of General Relativity.<\/span><\/p>\nBut in decades of searching they have never been detected, despite several years of operation from two huge laser instruments in the US and one in Italy.<\/span><\/p>\nTeams from the US detectors will speak in Washington DC at 15:30 GMT Thursday.<\/span><\/p>\nSpeculation is rife that they will announce the detection of gravitational waves by both the US instruments, which together make up the Laser Interferometer Gravitational Wave<\/span>\u00a0<\/span>Observatory (<\/span>Ligo<\/span><\/b>.)<\/span><\/span><\/p>\n“It is so exciting if this really is the first clear detection, as we’re expecting,” Dr Carolin Crawford from Cambridge University told the BBC’s Today programme. \u00a0“It will really mark a new era for astronomy.”<\/span><\/p>\nGravitational waves are concentric ripples that squeeze and stretch the fabric of space-time. They are caused by the movement of mass, but most are so weak that they have no measurable effect.<\/span><\/p>\nFor current technology to glimpse them, we need to find the waves – still incredibly subtle – that are radiating across the cosmos from extremely violent events, like explosions or collisions involving stars or black holes.<\/span><\/p>\nAt each Ligo detector, a laser beam is split in two and sent down identical, perpendicular 4km tunnels – then reflected back again. The two arms work like rulers, at right angles, made of light.<\/span>\u00a0<\/span><\/p>\n<\/noscript><\/a><\/span><\/div>\nFigure\u00a0<\/b><\/span>1\u00a0<\/b><\/span>The Ligo labs have an L-shaped

Albert Einstein, as a key prediction of his Theory of General Relativity.<\/span><\/p>\nBut in decades of searching they have never been detected, despite several years of operation from two huge laser instruments in the US and one in Italy.<\/span><\/p>\nTeams from the US detectors will speak in Washington DC at 15:30 GMT Thursday.<\/span><\/p>\nSpeculation is rife that they will announce the detection of gravitational waves by both the US instruments, which together make up the Laser Interferometer Gravitational Wave<\/span>\u00a0<\/span>Observatory (<\/span>Ligo<\/span><\/b>.)<\/span><\/span><\/p>\n“It is so exciting if this really is the first clear detection, as we’re expecting,” Dr Carolin Crawford from Cambridge University told the BBC’s Today programme. \u00a0“It will really mark a new era for astronomy.”<\/span><\/p>\nGravitational waves are concentric ripples that squeeze and stretch the fabric of space-time. They are caused by the movement of mass, but most are so weak that they have no measurable effect.<\/span><\/p>\nFor current technology to glimpse them, we need to find the waves – still incredibly subtle – that are radiating across the cosmos from extremely violent events, like explosions or collisions involving stars or black holes.<\/span><\/p>\nAt each Ligo detector, a laser beam is split in two and sent down identical, perpendicular 4km tunnels – then reflected back again. The two arms work like rulers, at right angles, made of light.<\/span>\u00a0<\/span><\/p>\n<\/noscript><\/a><\/span><\/div>\nFigure\u00a0<\/b><\/span>1\u00a0<\/b><\/span>The Ligo labs have an L-shaped

They are caused by the movement of mass, but most are so weak that they have no measurable effect.<\/span><\/p>\nFor current technology to glimpse them, we need to find the waves – still incredibly subtle – that are radiating across the cosmos from extremely violent events, like explosions or collisions involving stars or black holes.<\/span><\/p>\nAt each Ligo detector, a laser beam is split in two and sent down identical, perpendicular 4km tunnels – then reflected back again.

They are caused by the movement of mass, but most are so weak that they have no measurable effect.<\/span><\/p>\nFor current technology to glimpse them, we need to find the waves – still incredibly subtle – that are radiating across the cosmos from extremely violent events, like explosions or collisions involving stars or black holes.<\/span><\/p>\nAt each Ligo detector, a laser beam is split in two and sent down identical, perpendicular 4km tunnels – then reflected back again. The two arms work like rulers, at right angles, made of light.<\/span>\u00a0<\/span><\/p>\n<\/noscript><\/a><\/span><\/div>\nFigure\u00a0<\/b><\/span>1\u00a0<\/b><\/span>The Ligo labs have an L-shaped
