New discovery of gravitational waves: scientists have studied epic collisions of two ancient black holes – Science Exploration – cnBeta.COM

Researchers have just announced the largest and far-reaching black hole collisions observed to date, as well as three other black hole collisions. So far, scientists have observed 10 similar incidents.Of

In a scientific conference in Maryland, recent research found researchers to discuss the latest research related to gravitational waves. Gravitational waves are "涟漪" in place and time. The general production is caused by two objects that do not interfere with each other. The strongest gravitational wave comes from the collision of extremely dense objects such as black holes or neutron stars.

During the July-August 2017, there were four new members in the list of small but powerful gravitational wave makers.

The first is the one discovered on July 29, the largest and blackest black hole in history, which is 5 billion light-years of earth and 80 times the weight of the sun.

Gravitational waves travel at the speed of light, so this huge effect fell in fact 5 billion years ago.

At that time, the solar system we are in is not even produced. The combination of the two is so shocking that about five centuries of mass are connected in another form of energy, the gravity wave.

On the day of July 29, 2017, the land received this information.

Scientists, including Albert Einstein, first proposed the concept of gravitational waves in the early 20 th century, but it was not until 2015 that researchers discovered their clues.

Researchers on the planet must use enormous observers, but the current number is quite rare.

The latest discovery was discovered by two sets of laser intervention gravitational wave observers (Ligo) in the United States and Virgo Detectors in Europe (Italy).

Since Virgo has been launched in August 2017, it has a number of major discoveries with Ligo, such as the Neutron Star collision observation announced last October.Of

After that, both sets of equipment are in a state of downtime maintenance and maintenance upgrades, preparing for the next round of observations.

Officials said that Ligo's third observation plan was scheduled to open in early 2019. The Virgo Detector after the instrument update is also expected to participate again.

Astrophysicists hope that the next observation will reveal more calories. However, they will continue to be updated in the coming decades.

The European Space Agency (ESA) and the United States Space Agency (NASA) are collaborating on the development of a site observatory called the Laser Interferometer Space Antenna (Lisa).

It consists of three multi-million-mile spacecraft, the size and space, which means it can detect gravitational waves that are difficult to detect on the ground.

Lisa is scheduled to launch before the 2030s, but China also announced plans to build two-seat gravitational wave detectors this summer.
