Analysis of the Principle of Gravitational Wave Searching and Future Applications

Abstract

When thinking about waves, mankind will first come up with ripples of water. Similarly, gravitational waves are also ripples, but they are ripples of spacetime. Waves of water are generated due to an object dropping into the water. Likewise, gravitational waves are generated due to massive objects in space. The concept of it was announced by Einstein, which was then observed in 2015 by the LIGO collaboration, which opened up a whole new chapter of observational astronomy. Since that remarkable detection, study of gravitational waves has become incredibly important when conducting research in black hole and neutron star mergers, as well as other cosmic phenomena. By detecting gravitational waves, scientists can have a better understanding of the nature of gravity, and they can better investigate behaviors of matter under certain conditions. However, Current detectors, such as LIGO and Virgo, cannot perfectly detect and observe waves due to their sensitivity and low frequency range. Future upgrades of equipment, including next-generation detectors like the Einstein Telescope and the space-based LISA, may help detect weaker and further gravitational waves, with a larger frequency range. As gravitational wave astronomy continues to make progress, one can expect more advanced knowledge and findings of the universe, gravity, spacetime, and the most powerful events that occur in the cosmos.
