Mõnikord ei ole füüsika teadusel piisavalt palju informatsiooni, et ennustada, kuidas selle allika gravitatsioonilained ilmuvad. Teadlased loodavad avastada gravitatsioonilaineid sellistest süsteemidest, millest ei oldud varem teadlikud. Selliste gravitatsioonilainete otsimiseks ei saa ennustada omadusi nagu eelmiste gravitatsioonilainete puhul. See tähendab, et teadlased ei piira oma analüüsi modelleeritud või eeldatud signaaliga, see teeb plahvatuslike gravitatsioonilainete otsingud väga keeruliseks. Uute gravitatsioonilainete avastamine võimaldab saada uuelaadset informatsiooni Universumi kohta, mida muul viisil ei pruugi kunagi teada saada.<sup id="cite_ref-:0_3-6" class="reference"><a href="#cite_note-:0-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Gravitatsioonilainest_läbimineku_efektid"><span id="Gravitatsioonilainest_l.C3.A4bimineku_efektid"></span>Gravitatsioonilainest läbimineku efektid</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Gravitatsioonilained&veaction=edit&section=6" title="Muuda alaosa "Gravitatsioonilainest läbimineku efektid"" class="mw-editsection-visualeditor"><span>muuda</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Gravitatsioonilained&action=edit&section=6" title="Muuda alaosa "Gravitatsioonilainest läbimineku efektid" lähteteksti"><span>muuda lähteteksti</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/Fail:GravitationalWave_PlusPolarization.gif" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/b/b8/GravitationalWave_PlusPolarization.gif/220px-GravitationalWave_PlusPolarization.gif" decoding="async" width="220" height="220" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/b/b8/GravitationalWave_PlusPolarization.gif 1.5x" data-file-width="288" data-file-height="288" /></a><figcaption>Polariseerutud gravitatsioonilaine mõju osakeste ringile</figcaption></figure> <p>Gravitatsioonilained läbivad pidevalt Maad, kuid isegi kõige tugevamatel on imeväike mõju ning nende allikad on üldiselt kaugemal. Näiteks lained kahe musta augu liitumisest, GW150914-ga, jõudsid Maale pärast üle miljardi valgusaasta pikkust reisi pulsatsioonina aegruumis, mis muutis 4-km LIGO õla pikkust prootoni 1/10000 laiuse võrra. See muutus on samaväärne lähima galaktika kauguse muutusega ühe millimeetri võrra. Isegi äärmuslike gravitatsioonilainete toime on väga väike, nende toimet on võimalik märgata ainult keerukate detektoritega. </p><p>Me saame paremini mõista, mis on gravitatsioonilaine, vaadates, kuidas see mõjutab objekti, mida see läbib. Kujutage ette laeva merel. Kui veelaine läbib laeva paremalt vasakule, siis laev kõigub üles ja alla. Teiselt poolt, kui gravitatsioonilaine läbib samas suunas, laev muutub ühel hetkel pikkemaks, teisel lühemaks.<sup id="cite_ref-4bHAt_4-0" class="reference"><a href="#cite_note-4bHAt-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p><p>Nagu teiste lainete kirjeldamiseks, kasutatakse ka gravitatsioonilaine kirjeldamiseks mitmeid karakteristikud: </p> <ul><li><a href="/wiki/Amplituud" title="Amplituud">Amplituud</a> – näitab mitme protsendi võrra gravitatsioonilaine venitab või pigistab objekti. Veelainete puhul näitab amplituud, kui palju laine tõuseb ja langeb võrreldes merepinnaga. Amplituud siintoodud animatsioonis on umbes h = 0,5 (või 50%). Maad läbivad gravitatsioonilained on mitu sekstiljonit korda nõrgemad kui see – h ≈ 10–20.</li> <li><a href="/wiki/Sagedus" title="Sagedus">Sagedus</a> – tavaliselt tähistatakse f. See on sagedus, millega laine võngub (1 jagatud ajaga kahe järjestikuse maksimaalsete venitamiste või pigistamiste vahel).</li> <li><a href="/wiki/Lainepikkus" title="Lainepikkus">Lainepikkus</a> – tavaliselt tähistatakse λ, see on kaugus pikilaine kahe maksimaalse venitamise või pigistamise vahel.</li> <li><a href="/wiki/Kiirus" title="Kiirus">Kiirus</a> – kiirus, millega punkt laines (näiteks maksimaalse venitamise või pigistamise punkt) liigub. Gravitatsioonilainete väikeste amplituudide korral võrdub nende kiirus <a href="/wiki/Valguse_kiirus" title="Valguse kiirus">valguse kiirusega</a> (<a href="/wiki/Valguse_kiirus" title="Valguse kiirus">c</a>).</li></ul> <p>Gravitatsioonilaine kiirus, lainepikkus ja sagedus on seotud võrrandiga c = λf nagu valguslaine puhul. Siintoodud animatsioon võngub umbes kord kahe sekundi jooksul. See vastaks sagedusele 0,5 Hz ja lainepikkusele 600 000 km (~ 47 Maa läbimõõtu). </p><p>Eespool toodud näites on eeldatud, et laine on lineaarselt polariseerutud "pluss" polarisatsiooniga (kirjutatakse h +). Gravitatsioonilaine <a href="/wiki/Polarisatsioon" title="Polarisatsioon">polariseerumine</a> sarnaneb valguslaine polarisatsiooniga, välja arvatud see, et gravitatsioonilaine polarisatsioonide erinevus on 45 kraadi, mitte 90 kraadi. Nagu valguse polarisatsioon võib gravitatsioonilaine polarisatsioon olla ka ringpolariseerutud laine. Gravitatsioonilained on polariseerutud nende allika loomuse tõttu. </p> <div class="mw-heading mw-heading2"><h2 id="Viited">Viited</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Gravitatsioonilained&veaction=edit&section=7" title="Muuda alaosa "Viited"" class="mw-editsection-visualeditor"><span>muuda</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Gravitatsioonilained&action=edit&section=7" title="Muuda alaosa "Viited" lähteteksti"><span>muuda lähteteksti</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="reflist" style="list-style-type: decimal;"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-2IRWS-1"><span class="mw-cite-backlink"><a href="#cite_ref-2IRWS_1-0">↑</a></span> <span class="reference-text">Jaan-Juhan Oidermaa (toimetaja): <a rel="nofollow" class="external text" href="http://novaator.err.ee/v/universum/25d59e9e-15c1-4f3d-83cf-4febd6ae9a6c">"Teadlased nägid esimest korda gravitatsioonilaineid"</a>.
