“Latest Innovations and Discoveries in the Study of the Universe: Wave Gravity Detector and James Webb Space Telescope”

To explore and study the wider universe, humans need to create an innovation/invention, to make it easier for humans to explore, study and know what is in this universe.

The following are some of the latest innovations and discoveries to study the study of the universe, namely:

1. WAVE GRAVITY DETECTOR

A Gravity Wave Detector is a device used to detect gravitational waves, which are vibrations in space-time generated by very massive cosmic objects such as black holes or colliding stars. The concept of the Gravity Wave Detector was first proposed by the physicist Albert Einstein in his theory of general relativity in 1916, but it was not until the early 2000s that sufficiently advanced technology was developed to allow the detection of gravitational waves.

Gravity Wave Detectors work by measuring the change in distance caused by gravitational waves as they pass through the instrument. The detector has two very long parallel arms, usually L-shaped, each about several kilometers long. at the end of each arm, there is a mirror which is used to reflect the laser light emitted by the instrument.

If gravitational waves pass through the instrument, the distance between the mirrors on each arm will change, so that the laser beam reflected back from the mirror will have a different phase. This phase change can be detected and recorded by instruments, and used to confirm the presence of gravitational waves.

The largest and best known Gravity Wave Detector is the LIGO (Laser Interferometer Gravitational-Wave Observatory), which consists of two detectors in the United States: one in Hanford, Washington, and one in Livingston, Louisiana. LIGO began operations in 2002 and detected gravitational waves for the first time in 2015, when gravitational waves generated by the collision of two black holes were observed by the instrument. Other Gravity Wave Detectors under development or operational include Virgo in Italy and KAGRA in Japan.

The Gravity Wave Detector is providing new information about very massive cosmic objects, such as black holes and neutron stars, and opening new avenues for the study of astronomy and fundamental physics. The invention and development of the wave gravitational detector is one of the greatest achievements in astronomy and physics in recent decades.

2. JAMES WEBB SPACE TELESCOPE

The James Webb Space Telescope (James Webb Space Telescope or JWST for short) is a space telescope being developed by NASA, the United States Space Agency, with support from other space agencies such as ESA (European Space Agency) and CSA (Canadian Space Agency). JWST is scheduled to be launched on December 22, 2021 and will be placed in the Earth-Sun Lagrange Point 2 (L2) orbit, which is about 1.5 million kilometers from Earth.

JWST will replace the Hubble Space Telescope and is expected to provide new pictures of the wider and more distant universe than previous telescopes have been able to provide. JWST has several features that set it apart from other telescopes, including:
