gravitational wave 【物理學】引力波,重力波。

gravitino

Most of the new gravitational wave detection projects are using laser interferometers instead of resonant mass detectors because they are more sensitive 大多數引力波探測項目都是使用更為靈敏的激光干涉計探測儀而不是共振質量探測儀。

Since the shape of spacetime depends only on how mass is distributed , events that change the distribution of mass cause gravitational waves 既然時空結構的形狀僅取決于質量的分布,能夠改變質量分布的事件就能夠導致引力波的產生。

Geo 600 is a gravitational wave observatory in hanover , germany built by an international collaboration of scientists from the uk and germany Geo 600是位于德國漢諾威的一個引力波觀測站,由來自英德兩國的科學家們合作建設而成。

You can see how much the mirrors want to move due to gravitational waves ( or anything else ) by watching how much power is needed to hold them in lock 你可以通過觀察保持鏡子鎖定所需的能量來確定引力波想要把反射鏡移動多少。

Then there are plans to examine the gravitational wave background , which would show what the universe looked like a fraction of a second after the big bang 接下來的計劃是檢查引力波背景,這可以顯示大爆炸后瞬間宇宙的樣子。

But only a handful of neutron stars are paired up with other neutron stars that are close enough to show the indirect evidence of gravitational waves 但是只有少量的中子星是和其它中子星靠得足夠近并顯示出引力波存在的證據。

Nearly 40 years on , researchers around the world are still straining to see gravitational waves , so far without success 直至今日近40年的時間里,全世界的研究者都圍繞著發現重力場波動而進行著工作,但時至今日仍然沒有進展。

Precessing stars do radiate gravitational waves , but they ' re not the only ones . any asymmetry about the rotation axis will do 進動的星體確實會輻射引力波,但它們并非唯一的選擇。繞旋轉軸的任何不對稱都會導致引力波的產生。

Unfortunately , a passing gravitational wave will make only a tiny change in the distance the laser beams have to travel 不幸的是,在激光束所經過的路程過程中,行經的重力波只會稍微地對干涉波波長稍微改變一點點。

This is a systematic search of the sky , one location at a time , for any periodic gravitational wave coming from that location 這是對天空的一次系統的搜索,目標是從某方向來的周期性的引力波,每次只分析一個方向。

Today you said that the gravitational wave shows up as a little change in the frequency of the laser light because time is distorted 而今天你們又說因為引力波扭曲了時間,導致激光的頻率發生了一丁點的改變。

Gravitational waves change the interference pattern , so researchers look for them by examining changes in the pattern over time 因為引力波會改變這個干涉圖樣,研究者們將通過檢測圖樣的變化以搜尋引力波。

It takes events with a lot of energy to make gravitational waves that we can detect because spacetime is not very elastic 因為時空結構并不是富有彈性的,要產生我們能探測到的引力波將需要相當多的能量。

Scientists trying to detect gravitational waves ? ripples in the fabric of space - time ? are a reticent lot 科學家們為了試圖發現重力場波動? ?空間-時間四維結構的扭曲波動? ?的科學嘗試從未停止過。

Similarly , i don ' t expect the eventual detection of gravitational waves to directly produce any practical spinoffs 同樣的,我并不期望對引力波的最終發現能直接產生任何實際的副產品。

If the collapse if not perfectly spherical , the supernova will give off an intense burst of gravitational waves 如果蹋縮過程不是沿著完美的球形,超新星將在瞬間發出強烈的引力波。

Finn expects that merging massive black holes will be the first objects to have their gravitational waves detected 芬恩預測,大質量黑洞的合并事件,將是首度被測到重力波的波源。

Pulsars and supernovae are shown on the sky because scientists believe they emit gravitational waves 天球上標識出了脈沖星和和超新星遺跡,因為科學家們相信它們都會發射出引力波。

Supernovae remnants can leave behind pulsars or spinning neutron stars that may produce gravitational waves 超新星遺跡中可能還存留有脈沖星或自旋中子星,而這些都會產生引力波。
