Sentences with phrase «when spacetime»

But special relativity applies when spacetime is flat.

When spacetime is curved, the theory applies only «locally» — that is, over regions of spacetime small enough to be considered flat.

Theories also suggest that so - called primordial black holes could have arisen even earlier in cosmic history, when spacetime may have been expanding exponentially in a process called inflation.

Not exact matches

Gravity is caused when mass puckers the fabric of spacetime.

But Einstein showed that when you add mass, including planets, people, and even coconuts, it warps the fabric of spacetime.

The project continues to detect waves from similar events, offering new and incredible details about what happens when these black holes crash and warp the spacetime around them.

When the gravitational waters of spacetime are calm, the beams recombine at the junction and cancel each other out — the troughs of one beam's 1,064 - nanometer waves of laser light completely negate the crests of the second beam's waves.

An answer may come from the attempts the people are making to try to develop a theory of quantum gravity because under one of the models for this called up loop quantum gravity spacetime itself almost consists of, like, you can think of it is like a little a atom of spacetime; and one possibility is that when you start to cram everything very close together when space itself is packed down into a small enough point that it can't keep shrinking it, it can't keep compacting it.

A black hole arises when the warping around a point grows so severe that that spacetime in the area becomes like a funnel so steep that nothing can climb back out, as may happen when a massive star collapses.

That's when the patterns of mass density and spacetime ripples were imprinted into matter in the universe.

When masses abruptly change their rate or direction of motion, they should send ripples through spacetime.

In 1915, Albert Einstein explained that gravity arises when massive objects such as Earth warp spacetime, bending the otherwise straight trajectories of free - falling objects.

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.

Gravitational lenses occur when very massive objects — such as clusters of galaxies — warp spacetime around them, causing light (and anything else) traveling nearby to take a curved path.

So far, they have succeeded in creating a stable four - dimensional spacetime, when viewed at large distances.

In curved spacetimes, when we compare two observers at large separation, we can no longer use the «locally flat» approximation.

Research on the dynamics of the quantized model revealed an amazing result: processes modeled using the quantum theory on quantum spacetime turned out to exhibit the same dynamics as when the quantum theory takes place in a classical continuous spacetime, i.e. the kind we know from everyday experience.

The equation shows that spacetime geometry equals mass - energy density when adjusted with the proper units and numerical constants.

When he applied this equation to the entire universe, Einstein found that the universe would be unstable, easily disturbed into a state in which spacetime would be either expanding or collapsing.

The first direct detection of gravitational waves occurred in mid-September 2015 (but announced February 11, 2016) with twin LIGO detectors in Hanford, WA and Livingston, LA (both USA) when ripples of spacetime from the last fraction of a second of the merger of two black holes with masses 29 and 36 solar masses combined to form a 62 - solar mass black hole with 3 solar masses of energy radiated away as gravitational waves in that last fraction of a second.

It's as if physicists have created a virtual tripwire that notifies us when an invisible gravitational wave intruder rumbles local spacetime.

When an energetic event occurs (like a black hole merger or neutron star collision), spacetime becomes violently disturbed and energy is carried away from the event in the form of gravitational waves — like ripples traveling across the water's surface after dropping a pebble in a pond.

While you can play this game alone, Lovers in a Dangerous Spacetime really opens up when you and three other players control the various weapons and gadgets aboard your spaceship.

While Lovers in a Dangerous Spacetime was made with co-op in mind, it's still a ton fun when playing solo.

The need to constantly communicate and synchronize action, when playing locally with another human being, is one of the most attractive elements of Lovers in a Dangerous Spacetime and anyone who has a close friend who's into video games should give the experience a try.

Even with players who have clearly divided their responsibilities and communicate well, Lovers in Dangerous Spacetime can be very difficult and it's a great idea to take breaks at times, especially when frustration seems to set in.

When you give the sequel its full name Evoland 2: A Slight Case of Spacetime Continuum Disorder, you get a feeling for the unique selling point.

Thus, a little over a decade later when Einstein wrote his general relativity theory, he did not know that the original work of Maxwell already indicated the unification of gravitation and electromagnetics, and indicated the ease with which local spacetime could be electrogravitationally curved locally and engineered.

I did find his insisting that all photons being identical, # 3@23min, but of course he is not invalidating E = hv, seems he is only speaking of when you look at existence (amplitudes) in spacetime.
