Researchers from the <a href=\"https:\/\/www.otago.ac.nz\/\" target=\"_blank\" rel=\"noreferrer noopener\">University of Otago<\/a> and other institutions have developed the first-ever numerical simulations that track the entire journey of a gravitational wave from the past to the future. Using this new approach, they studied how these waves interact with black holes, which can absorb or scatter the waves.<\/p>\n\n\n\n<p class=\"\">The team used advanced mathematical techniques to model these waves across a \u201cnull infinity\u201d region, representing spacetime boundaries where light and gravitational waves travel. This is crucial for understanding how waves behave as they move through the universe and interact with objects like black holes. By applying the mathematical framework of the generalized conformal field equations, the team was able to bring the infinite distance into a manageable computational domain, enabling them to track waves with incredible precision.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img  decoding=\"async\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAAlwSFlzAAAOxAAADsQBlSsOGwAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  alt=\"\"  class=\" pk-lazyload\"  data-pk-sizes=\"auto\"  data-pk-src=\"https:\/\/upload.wikimedia.org\/wikipedia\/commons\/2\/25\/Black_hole_collision_and_merger_releasing_gravitational_waves.jpg\" ><figcaption class=\"wp-element-caption\">The image depicts the collision and merger of two black holes, an event that led to <a href=\"https:\/\/www.ligo.caltech.edu\/\" target=\"_blank\" rel=\"noreferrer noopener\">LIGO<\/a>\u2018s first detection of gravitational waves, <a href=\"https:\/\/www.ligo.caltech.edu\/page\/press-release-gw150914\" target=\"_blank\" rel=\"noreferrer noopener\">GW150914<\/a>.

They found that about 8.5% of the energy scattered back into space for waves with weak amplitudes, while stronger waves had around 20% of their energy scattered. This revealed that spacetime is highly resistant to deformation, with most of the energy absorbed by the black hole rather than escaping into the universe.<\/p>\n\n\n\n<p class=\"\">These results, published in <a href=\"https:\/\/journals.aps.org\/prl\/abstract\/10.1103\/PhysRevLett.134.161401\" target=\"_blank\" rel=\"noreferrer noopener\"><em>Physical Review Letters<\/em><\/a>, were measured using two important quantities, Bondi energy, and Bondi news, which help determine the energy and radiation associated with gravitational waves. The data confirmed that energy is conserved during the interaction between waves and the black hole. It also provided new insights into how black holes scatter gravitational waves, vital for understanding cosmic phenomena detected by observatories like LIGO. While challenges remain, the study opens new avenues for understanding the fundamental properties of the universe\u2019s most mysterious objects.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 id=\"references\" class=\"wp-block-heading\">References<\/h1>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\">Frauendiener, J., Stevens, C., & Thwala, S.
