Sentences with phrase «gravitational waves stretching»

Gravitational waves stretch and compress spacetime, subtly distorting objects they pass through.

Not exact matches

Like a ball bouncing off a rubber sheet, any accelerating mass should send out gravitational waves, ripples that cause space itself to stretch and squeeze.

But researchers had long sought more direct evidence for inflation in the form of gravitational waves, which squeeze and stretch space.

In one way, an oncoming gravitational wave can squeeze space vertically and stretch it horizontally, and then vice versa, in a repeating cycle.

Gravitational ripples are tiny: LIGO is tuned to detect waves that stretch and squeeze the arms by a thousandth of the diameter of a proton.

When a gravitational wave moves through the detector, though, it should stretch one arm of LIGO while shortening the other, changing the path of the beams and causing the rejoined waves to produce a detectable pattern of light.

A gravitational wave from a distance source stretches space by an infinitesimal amount, and to detect that rhythmic stretching LIGO employs two gigantic optical devices called interferometers, which essentially act as gigantic rulers.

LIGO consists of two gargantuan optical instruments called interferometers, with which physicists look for the nearly infinitesimal stretching of space caused by a passing gravitational wave.

Physicists on Earth are hunting gravitational waves with laser interferometers — devices with kilometers - long arms that will change length slightly if a wave ripples past, squeezing and stretching space.

These changes, scientists predict, will be caused by a gravitational wave that stretches and squeezes space - time as it passes through the instruments.

If two people were floating near, say, a pair of merging black holes, the space between them would grow and shrink as space - time was stretched and distorted by gravitational waves.

When gravitational waves reach the earth, the waves stretch and squeeze space.

Relativity predicts exactly how much stretching and squeezing a gravitational wave should do.

We are attempting to detect the gravitational waves by hanging two huge mirrors from wires, each pair of mirrors about two and a half miles apart, and as the waves pass, the mirrors ride on that stretching and squeezing space so they are pushed apart and pulled together, back and forth.

Finally, the newborn universe could have been agitated by distortions in space itself known as gravitational waves, which would stretch the whole cosmos in one direction and compress it in a perpendicular direction.

The neutron stars» union also gave researchers the opportunity to gauge the universe's expansion rate, by measuring the distance of the collision using gravitational waves and comparing that to how much the wavelength of light from the galaxy was stretched by the expansion.

A passing gravitational wave would generally stretch the arms by different amounts, and that's what the LIGO team spotted.

As a gravitational wave passes it will compress one arm and stretch the other while an interferometer where they meet attempts to measure the minute length difference — less than the width of an atomic nucleus.

Inflation stretched that spacetime jittering into gravitational waves billions of light - years in wavelength.

Gravitational waves literally stretch space itself.

Other cosmic phenomena such as supernovae in the Milky Way and colliding neutron stars in our galactic neighborhood should also produce detectable gravitational waves, each with their own accompanying revolutionary insights, but so far all three of LIGO's detections have been death - rattles from merging pairs of black holes in remote stretches of the universe.

On 14 September 2015, at 9:50:45 universal time, humans detected for the first time a gravitational wave — a rippling, infinitesimal stretching of spacetime itself set off when two black holes spiraled into each other.

When a gravitational wave passes by, it stretches the paths each laser beam travels.

The discovery of gravitational waves might give us a view of the cosmos that stretches all the way back to the big bang and tell us if there's a theory of everything

Weiss realized that output could reveal a passing gravitational wave, which generally would stretch the arms by different amounts.

Weber argued that those ripples — gravitational waves — would stretch his cylinders and make them vibrate like tuning forks.

A passing gravitational wave should slightly stretch one beam while compressing the other.

LIGO's interferometers bounce laser beams between mirrors at the opposite ends of 4 - kilometre - long vacuum pipes, aiming to detect passing gravitational waves that stretch and compress the length of the pipes — along with the rest of space.

Gravitational waves are a measure of strain in space, an effect of the motion of large masses that stretches the fabric of space - time — a way of viewing space and time as a single, interweaved continuum.

Feb. 28, 2018: Gravitational waves are wrinkles in space - time that stretch and squeeze the distances between objects.

Should a gravitational wave travel through our planet, a tiny change in distance may be recorded by the interferometer — this represents the minute squeezing and stretching of spacetime that occurs as gravitational waves propagate.
