Since we started wondering about it, we have always tried to understand what light is. Today we know that light propagates as an electromagnetic wave that travels in a straight line at the speed of light and interacts with the matter. The knowledge of these interactions can be subsequently applied to analyse other system with a high degree of accuracy. A clear example along this line is the measurement of the thickness of a hair through the interaction of it with a beam of light. By studying the diffraction pattern created after the interaction, we can study the physical properties of hair. Focusing on the properties of diffraction and interference through electromagnetic waves, we can extend the previous concepts to detect gravitational waves. This is achieved by the superposition of two light beams and the variation in the interference pattern due to perturbations of the wavelengths. In this way, the detection of gravitational waves in 2015 has become one of the greatest experimental achievements of the era of modern physics and astronomy. At the ICFO photonics research centre in Castelldefels, and after a small-scale replication of the Michelson interferometer, we can understand how the detection of the collision of two black holes occurred with the study of variations in the interference pattern. Thus, it could be observed that if we varied the wavelength of one of the light beams, its interference pattern was disturbed. These kind of techniques, with its unprecedented accuracy, opens the gate to leading research centres like LIGO to explore new areas of science where the human knowledge is pushed to its limits.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=\u00bb4.16″ _module_preset=\u00bbdefault\u00bb background_color=\u00bb#e1e1e1″ global_colors_info=\u00bb{}\u00bb][et_pb_column type=\u00bb4_4″ _builder_version=\u00bb4.16″ _module_preset=\u00bbdefault\u00bb background_color=\u00bb#e1e1e1″ global_colors_info=\u00bb{}\u00bb][et_pb_image src=\u00bbhttps:\/\/outreach-wp.ixole.es\/wp-content\/uploads\/2023\/05\/9_llumUnivers.jpg\u00bb title_text=\u00bb9_llumUnivers\u00bb url=\u00bbhttps:\/\/outreach-wp.ixole.es\/wp-content\/uploads\/2023\/05\/9_llumUnivers.jpg\u00bb _builder_version=\u00bb4.17.4″ _module_preset=\u00bbdefault\u00bb global_colors_info=\u00bb{}\u00bb][\/et_pb_image][et_pb_post_nav _builder_version=\u00bb4.16″ _module_preset=\u00bbdefault\u00bb title_font=\u00bb|600|||||||\u00bb title_text_color=\u00bb#918050″ global_colors_info=\u00bb{}\u00bb][\/et_pb_post_nav][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=\u00bb1_3,1_3,1_3″ use_custom_gutter=\u00bbon\u00bb gutter_width=\u00bb1″ make_equal=\u00bbon\u00bb admin_label=\u00bbrow\u00bb module_class=\u00bb et_pb_row_fullwidth\u00bb _builder_version=\u00bb4.16″ background_size=\u00bbinitial\u00bb background_position=\u00bbtop_left\u00bb background_repeat=\u00bbrepeat\u00bb width=\u00bb100%\u00bb width_tablet=\u00bb100%\u00bb width_phone=\u00bb\u00bb width_last_edited=\u00bbon|desktop\u00bb max_width=\u00bb100%\u00bb max_width_tablet=\u00bb100%\u00bb max_width_phone=\u00bb\u00bb max_width_last_edited=\u00bbon|desktop\u00bb custom_padding=\u00bb0px||0px|\u00bb make_fullwidth=\u00bbon\u00bb use_custom_width=\u00bboff\u00bb width_unit=\u00bbon\u00bb global_colors_info=\u00bb{}\u00bb][et_pb_column type=\u00bb1_3″ _builder_version=\u00bb4.16″ background_color=\u00bb#e1e1e1″ custom_padding=\u00bb|45px||45px|false|false\u00bb global_colors_info=\u00bb{}\u00bb custom_padding__hover=\u00bb|||\u00bb][\/et_pb_column][et_pb_column type=\u00bb1_3″ _builder_version=\u00bb4.16″ background_color=\u00bb#e1e1e1″ custom_padding=\u00bb|45px||45px|false|false\u00bb global_colors_info=\u00bb{}\u00bb custom_padding__hover=\u00bb|||\u00bb][\/et_pb_column][et_pb_column type=\u00bb1_3″ _builder_version=\u00bb4.16″ background_color=\u00bb#e1e1e1″ custom_padding=\u00bb|45px||45px|false|false\u00bb global_colors_info=\u00bb{}\u00bb custom_padding__hover=\u00bb|||\u00bb][et_pb_button button_url=\u00bb@ET-DC@eyJkeW5hbWljIjp0cnVlLCJjb250ZW50IjoicG9zdF9saW5rX3VybF9wb3N0Iiwic2V0dGluZ3MiOnsicG9zdF9pZCI6IjYzNjUifX0=@\u00bb button_text=\u00bbTornar als posters\u00bb button_alignment=\u00bbleft\u00bb admin_label=\u00bbBot\u00f3n Dorado\u00bb module_id=\u00bbbotons\u00bb module_class=\u00bbbotons\u00bb _builder_version=\u00bb4.16″ _dynamic_attributes=\u00bbbutton_url\u00bb custom_button=\u00bbon\u00bb button_text_color=\u00bb#918050″ button_border_color=\u00bb#918050″ button_icon_color=\u00bb#918050″ button_on_hover=\u00bboff\u00bb custom_css_main_element=\u00bbmargin-top: 10px;\u00bb custom_css_after=\u00bb margin-left: 0px !important;\u00bb button_text_color_hover=\u00bb#918050″ button_border_color_hover=\u00bb#918050″ button_border_radius_hover=\u00bb0″ button_letter_spacing_hover=\u00bb0″ saved_tabs=\u00bball\u00bb global_colors_info=\u00bb{}\u00bb button_text_size__hover_enabled=\u00bboff\u00bb button_one_text_size__hover_enabled=\u00bboff\u00bb button_two_text_size__hover_enabled=\u00bboff\u00bb button_text_color__hover_enabled=\u00bbon\u00bb button_text_color__hover=\u00bb#918050″ button_one_text_color__hover_enabled=\u00bboff\u00bb button_two_text_color__hover_enabled=\u00bboff\u00bb button_border_width__hover_enabled=\u00bboff\u00bb button_one_border_width__hover_enabled=\u00bboff\u00bb button_two_border_width__hover_enabled=\u00bboff\u00bb button_border_color__hover_enabled=\u00bbon\u00bb button_border_color__hover=\u00bb#918050″ button_one_border_color__hover_enabled=\u00bboff\u00bb button_two_border_color__hover_enabled=\u00bboff\u00bb button_border_radius__hover_enabled=\u00bbon\u00bb button_border_radius__hover=\u00bb0″ button_one_border_radius__hover_enabled=\u00bboff\u00bb button_two_border_radius__hover_enabled=\u00bboff\u00bb button_letter_spacing__hover_enabled=\u00bbon\u00bb button_letter_spacing__hover=\u00bb0″ button_one_letter_spacing__hover_enabled=\u00bboff\u00bb button_two_letter_spacing__hover_enabled=\u00bboff\u00bb button_bg_color__hover_enabled=\u00bboff\u00bb button_one_bg_color__hover_enabled=\u00bboff\u00bb button_two_bg_color__hover_enabled=\u00bboff\u00bb][\/et_pb_button][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" La luz y el universo\u00d3scar Vaz V\u00e1zquez Col\u00b7Legi Santo Angel – Gav\u00e0 We have realized that the study of light brings progress to science.
