Video answer: What types of sources cause gravitational waves?
Top best answers to the question «What can cause a gravitational wave»
The strongest gravitational waves are produced by cataclysmic events such as colliding black holes, supernovae (massive stars exploding at the end of their lifetimes), and colliding neutron stars.
FAQ
Those who are looking for an answer to the question «What can cause a gravitational wave?» often ask the following questions:
👋 What is a gravitational wave?
- A gravitational wave is an invisible (yet incredibly fast) ripple in space. Gravitational waves travel at the speed of light (186,000 miles per second).
- A gravitational wave is a ___________ wave?
- Can gravitational wave be canceled?
- How gravitational wave detectors work?
👋 What exactly is a gravitational wave?
- gravitational wave. noun. A wave induced in a fluid, especially the ocean or atmosphere, by the interaction of gravity with other forces on the motion of the fluid. A gravitational wave. Not in technical use.
- What are the effects of a gravitational wave?
- What is the mechanism of gravitational wave generation?
- What is the speed of a gravitational wave?
👋 What is a gravitational wave strain?
These propagating phenomena are known as gravitational waves. As a gravitational wave passes an observer, that observer will find spacetime distorted by the effects of strain. Distances between objects increase and decrease rhythmically as the wave passes, at a frequency equal to that of the wave.
- What is the wavelength of a gravitational wave?
- How do gravitational wave detectors work?
- How does a gravitational wave form?

How much gravitational wave distors space?How does a gravitational wave travel in space?
- A gravitational wave is an invisible (yet incredibly fast) ripple in space. Gravitational waves travel at the speed of light (186,000 miles per second). These waves squeeze and stretch anything in their path as they pass by.
How do we measure gravitational waves?
- Gravitational waves can be measured using a laser interferometer sophisticated enough to detect ripples in the fabric of spacetime on the scale of angstroms. The ripples are caused by collisions of massive objects in space, and in order to be detectable by instrumentation on Earth,...
- The most powerful gravitational waves are created when objects move at very high speeds. Some examples of events that could cause a gravitational wave are: when a star explodes asymmetrically (called a supernova) when two big stars orbit each other
Not exactly. If you are close enough to the source of the event that the gravitational wave could damage you at all, you would be obliterated by other massive energies released by the event, whether the gravitational wave itself would kill you or not.
What are gravitational waves?- Gravitational waves are invisible ripples in the fabric of space-time. They are caused by some of the most violent and energetic events in the universe.

What causes gravitational waves?
- Credit: NASA What causes gravitational waves? The most powerful gravitational waves are created when objects move at very high speeds. Some examples of events that could cause a gravitational wave are: If playback doesn't begin shortly, try restarting your device.
- But it would take a very different type of telescope — one that can see gravitational waves. The Webb, the Hubble, and even a future radio telescope on the far side of the moon are all telescopes that capture some form of electromagnetism (which include visible light, infrared light, radio waves, microwaves, ultraviolet, and so on).

What is the primary tool of gravitational wave astronomy?
- The present-day generation of laser interferometers has reached the necessary sensitivity to detect gravitational waves from astronomical sources, thus forming the primary tool of gravitational-wave astronomy .
- Astrophysicists expect that some gravitational waves passing the Earth may be as large as h ≈ 10 −20, but generally no bigger. A simple device theorised to detect the expected wave motion is called a Weber bar – a large, solid bar of metal isolated from outside vibrations.
Continuous gravitational waves are thought to be produced by a single spinning massive object like a neutron star. Any bumps on or imperfections in the spherical shape of this star will generate gravitational waves as it spins. If the spin-rate of the star stays constant, so too are the gravitational waves it emits.

How many gravitational wave detectors are there?
- At present there are three gravitational wave detectors in function. There is another Gravitational Wave detectot called VIRGO located in Santo Stefano a Macerata, near the city of Pisa, Italy. Why do we need three detectors? This is because more detectors will help to know the position of the stars more precisely.
- The first GW was identified in 2015 by the Laser Interferometer Gravitational-Wave Observatory (Ligo), an international project whose success won the 2017 Nobel prize in physics for three of its key proponents. Ligo consists of two massive detectors in the American states of Washington and Louisiana.
- The first sound is from modeled gravitational waves detected by LIGO Dec. 26, 2015, when two black holes merged. This is then compared to the first-ever gravitational waves detected by LIGO Sept. 14, 2015, when two higher-mass black holes merged.
LIGO operates two gravitational wave observatories in unison: the LIGO Livingston Observatory ( 30°33′46.42″N 90°46′27.27″W) in Livingston, Louisiana, and the LIGO Hanford Observatory, on the DOE Hanford Site ( 46°27′18.52″N 119°24′27.56″W), located near Richland, Washington.
What happens to the detector when a gravitational wave strikes?- Let us keep our camera trained on the detector, so the detector remains where it is. The changing distance to the light source, and also the changing distances between the light pulses, and some of the changes in distance between light pulses and detector or source, are due to the gravitational wave.
- Answer Wiki. We know that quantum objects should emit gravitons, which are the quantum version of gravitational waves, under similar conditions to non-quantum objects. As is well-known, an atom in an excited energy state has a probability to emit a photon (i.e. an electromagnetic wave) in order to go down to a lower energy state.
How does the speed of light affect a gravitational wave?
- Gravitational waves travel at the speed of light (186,000 miles per second). These waves squeeze and stretch anything in their path as they pass by. A gravitational wave is an invisible (yet incredibly fast) ripple in space.
- When a gravitational wave passes by Earth, it squeezes and stretches space. LIGO can detect this squeezing and stretching. Each LIGO observatory has two “arms” that are each more than 2 miles (4 kilometers) long. A passing gravitational wave causes the length of the arms to change slightly.

- A gravitational wave is an invisible (yet incredibly fast) ripple in space. Gravitational waves travel at the speed of light (186,000 miles per second). These waves squeeze and stretch anything in their path as they pass by.
- A passing gravitational wave causes the length of the arms to change slightly. The observatory uses lasers, mirrors, and extremely sensitive instruments to detect these tiny changes.
- These first gravitational waves happened when two black holes crashed into one another. The collision happened 1.3 billion years ago. But, the ripples didn’t make it to Earth until 2015!
- The most powerful gravitational waves are created when objects move at very high speeds. Some examples of events that could cause a gravitational wave are: An artist’s animation of gravitational waves created by the merger of two black holes.
- As a gravitational wave passes an observer, that observer will find spacetime distorted by the effects of strain. Distances between objects increase and decrease rhythmically as the wave passes, at a frequency equal to that of the wave.
