Can gravitational waves destroy a planet?

Science Alert points out that there’s nothing in the universe that’s known to expel the necessary amount of energy to form a black hole from gravitational waves. However, if it does happen and it happens close enough to Earth, destruction would be certain for the planet.

Do stars emit gravitational waves?

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.

What proves gravitational waves?

Gravitational waves can penetrate regions of space that electromagnetic waves cannot. Precise measurements of gravitational waves will also allow scientists to test more thoroughly the general theory of relativity. In principle, gravitational waves could exist at any frequency.

What if gravitational waves hit Earth?

As a result, time and space itself are stretched causing a slight wobble. But if we were closer to this violent event and the waves were much bigger, this impact could potentially tear our planet apart, triggering powerful continent-splitting earthquakes, volcanic eruptions and epic storms.

What happens when gravitational waves collide?

Gravitational-wave scientists reveal that when two black holes collide and merge, the remnant black hole ‘chirps’ not once, but multiple times, emitting gravitational waves — intense ripples in the fabric space and time — that inform us about its shape.

Why do gravitational waves get weaker?

Due to the weakness of the coupling of gravity to matter, gravitational waves experience very little absorption or scattering, even as they travel over astronomical distances. In particular, gravitational waves are expected to be unaffected by the opacity of the very early universe.

Do gravitational waves lose energy?

Yes. Objects in orbit lose energy in the form of gravitational waves that they emit. The amount of energy radiated away is normally extremely small – which is why we need large events such as black hole mergers to just barely detect gravitational waves.

How do gravitational waves propagate?

Gravitational Waves are, in their most basic sense, ripples in spacetime. If a star explodes as a supernova, gravitational waves carry energy away from the detonation at the speed of light. If two black holes collide, they will cause these ripples in spacetime to propagate like ripples across the surface of a pond.

What happens when a gravitational wave hits Earth?

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.

What are the ripples of space gravitational waves?

Scientists call these ripples of space gravitational waves. Gravitational waves are invisible. However, they are incredibly fast. They travel at the speed of light (186,000 miles per second). Gravitational waves squeeze and stretch anything in their path as they pass by.

Why is it so hard to detect gravitational waves?

Credit: LIGO/T. Pyle But these types of objects that create gravitational waves are far away. And sometimes, these events only cause small, weak gravitational waves. The waves are then very weak by the time they reach Earth. This makes gravitational waves hard to detect. How do we know that gravitational waves exist?
