[漢羅] 模擬宇宙 ê 暗物質

咱 ê 宇宙是毋是有足濟好兄弟? 這張 暗物質 圖 看起來可能是按呢。 這个看袂著 ê 暗物質 產生 ê 重力,to̍h 是目前用來解說這寡現象 ê 主要理路: 星系是按怎會轉踅遐爾緊星系是按怎會踅星系團遐爾緊重力透鏡是按怎會 kā 光線拗彎甲遐爾厲害可見物質 是按怎會 tī 現此時 ê 宇宙 kah 宇宙 微波背景 攏揣有? 美國自然史博物館 內底 ê Hayden 天象館 ê 太空-Sió「烏暗宇宙」內底,嘛用這張影像來強調,四界攏是 ê 暗物質是按怎創治咱 ê 宇宙。 這張 詳細 ê 電腦模擬圖 烏色 ê 部份,是暗物質 ê 複雜雲絲。 伊 tī 宇宙內底 四界攏是,to̍h 親像是 蜘蛛網 仝款。 毋閣柑仔色、一簇一簇、較散 ê 部份,是咱較熟似 ê 重子 物質。 這寡模擬 ê 統計結果 kah 天文觀測 ê 結果有合。 雖罔講 暗物質 實在是足奇怪 ê,而且咱到今 猶毋知 伊 ê 形體 到底是生做啥款? 毋閣上驚人 ê 是,伊已經毋是這个 宇宙內底上奇怪 ê 重力 來源矣。 這馬逐家煞 kā 目標囥 tī 暗能量,這是一个閣較齊齊 ê 反重力 來源,應該是規个宇宙脹大 ê 主要原因。

[English] Dark Matter in a Simulated Universe

Is our universe haunted? It might look that way on this dark matter map. The gravity of unseen dark matter is the leading explanation for why galaxies rotate so fast, why galaxies orbit clusters so fast, why gravitational lenses so strongly deflect light, and why visible matter is distributed as it is both in the local universe and on the cosmic microwave background. The featured image from the American Museum of Natural History’s Hayden Planetarium Space Show Dark Universe highlights one example of how pervasive dark matter might haunt our universe. In this frame from a detailed computer simulation, complex filaments of dark matter, shown in black, are strewn about the universe like spider webs, while the relatively rare clumps of familiar baryonic matter are colored orange. These simulations are good statistical matches to astronomical observations. In what is perhaps a scarier turn of events, dark matter – although quite strange and in an unknown form – is no longer thought to be the strangest source of gravity in the universe. That honor now falls to dark energy, a more uniform source of repulsive gravity that seems to now dominate the expansion of the entire universe.
