什麼是宇宙?

宇宙是所有時間、空間與其包含的內容物所構成的統一體。它包含了行星、恆星、星系、星系際空間、次原子粒子以及所有的物質與能量,宇指空間,宙指時間。

根據歷史記載,人類曾經提出宇宙學、天體演化學與科學模型,解釋人們對於宇宙的觀察。最早的理論為地心說,由古希臘哲學家與印度哲學家所提出。數世紀以來,逐漸精確的天文觀察,引領尼古拉斯·哥白尼提出以太陽系為主的日心說,以及經約翰內斯·克卜勒改良的橢圓軌道模型;最終艾薩克·牛頓的重力定律解釋了前述的理論。後來觀察方法逐漸改良,引領人類意識到太陽系位於數十億恆星所形成的星系,稱為銀河系;隨後更發現,銀河系只是眾多星系之一。在最大尺度範圍上,人們假定星系的分布平均,且各星系在各個方向之間的距離皆相同,這代表著宇宙既沒有邊緣,也沒有所謂的中心。透過星系分布與譜線的觀察,產生了許多現代物理宇宙學的理論。20世紀前期,人們發現到星系具有系統性的紅移現象,表明宇宙正在膨脹;藉由宇宙微波背景輻射的觀察,表明宇宙具有起源。最後,1990年代後期的觀察,發現宇宙的膨脹速率正在加快,顯示有可能存在一股未知的巨大能量促使宇宙加速膨脹,稱做暗能量。而宇宙的大多數質量則以一種未知的形式存在著,稱做暗物質。

大爆炸理論是當前描述宇宙發展的宇宙學模型。目前主流模型,推測宇宙年齡為137.99±0.21 億年。大爆炸產生了空間與時間,充滿了定量的物質與能量;當宇宙開始膨脹時,物質與能量的密度也開始降低。在初期膨脹過後,宇宙開始大幅冷卻,引發第一波次原子粒子的組成,稍後則合成為簡單的原子。這些原始元素所組成的巨大星雲,藉由重力結合起來形成恆星。

探討宇宙謎團

努力挖掘未知事物

外星生物

It is a collective term for human beings of intelligent life outside the earth. From ancient times to the present, humans have always guessed, imagined, studied and explored whether there are aliens on other planets, and what aliens and their civilization are like. Some people blame the aliens and their influence on the products of civilization or UFOs on the earth that are difficult to explain with science. However, due to the relationship between collective consciousness and frequency, today's surface civilization cannot actually detect whether there are aliens or even alien life.

恆星死亡

If a star can undergo a nuclear fusion reaction, it can contend with the force of gravitational contraction. However, any star’s nuclear fusion fuel will run out one day. When the nuclear fusion reaction stops and gravity wins, the planet will die.

黑洞內部

A black hole is an area where the acceleration of gravity is extremely strong in time and space, so that there are no particles, or even electromagnetic radiation, like an area where light cannot escape. General relativity predicts that a dense enough mass can distort space-time and form a black hole; the boundary from which it is impossible to escape from this region is called the event horizon. Although the event horizon has a huge impact on the fate and condition of objects passing through it, observations of the area seem to have failed to detect any features. In many ways, a black hole is like an ideal black body, it does not reflect light. In addition, quantum field theory in curved space-time predicts that the Hawking radiation emitted by the event horizon, like the spectrum of a black body, can be used to measure temperature inversely proportional to mass. In a stellar black hole, this temperature is as high as billions of K, so it is basically impossible to observe.

Since the first modular assembly was assembled and launched in 1998, this multinational cooperation and orbit-built international space station has become a long-term stable space laboratory and observatory. It can also become a future mankind on the moon. , Mars and asteroid exploration relay station, providing transportation and maintenance functions. This call sign is designated as the "Station Alpha" International Space Station. The current total length is about 72.8 meters, the width is about 108.5 meters, and the height is about 20 meters. It is about 330 kilometers to 413 kilometers high in an orbit at an average of about 330 kilometers per second. The 7.66-kilometer high-speed flight (22.3 times the speed of sound at sea level) circumnavigates the earth about 15 and a half times a day, allowing researchers to conduct various scientific experiments in space and microgravity environments, as well as observations of meteorology and astronomy on the earth .
Our galaxy is composed of 200 to 400 billion stars and is full of interstellar matter. The Milky Way and its gravitationally bound satellite galaxies, such as the Sagittarius dwarf galaxy, the Ursa Major dwarf galaxy, and the Canis Major dwarf galaxy. The reference here is the orbit diameter of the T-dwarf galaxy in Leo, which is the farthest galaxy in the subgroup of the Milky Way. A group of galaxies consisting of at least 47 galaxies.
Since the first artificial satellite was launched into the sky, about 6,600 artificial satellites have been launched globally, of which 3,600 are still in space, only about 1,000 are operating effectively, and the rest have become space junk. According to statistics from the "Cosmos Today" website, there are 1071 satellites in operation, of which about 500 are low-Earth orbit satellites, 50 are medium orbit satellites (20,000 km), and the rest are geostationary orbit satellites (36,000 km).
NASA has published a new discovery. Data collected through Curiosity showed that organic matter existed on Mars 3 billion years ago. As for whether these traces left by creatures, it is not yet possible to judge.

Special phenomenon

SOLAR ECLIPSE.

是一種天文現象,屬於食的一種,只在月球運行至太陽與地球之間時發生。這時,對地球上的部分地區來說,月球位於太陽前方,因此來自太陽的部分或全部光線被擋住,看起來好像是太陽的一部分或全部消失了。日食只在朔,即月球與太陽呈現合的狀態時發生。 日食分為四種,包括日全食、日環食、日偏食和全環食,其中較罕見的是全環食,只發生在地球表面與月球本影尖端非常接近的情形下,這時不同地區會出現日偏食、日全食和日環食三種不同的日食。日全食經常吸引許多遊客和天文愛好者特地到海外去觀賞日全食,也會有旅行社推出專門為這些遊客設計的行程。

SOLAR STORM

太陽風暴是太陽引起的現象,通常與來自太陽黑子活動區的太陽閃焰引起的日冕雲和日冕大量拋射相關聯,也有少數與日冕洞關。大多數活著的恆星都會對太陽物理學領域研究的太空天氣產生干擾;這是與許多領域,像是恆星天文學和行星科學結合的一個學門。在太陽系,太陽可以產生劇烈的地磁和質子風暴,對無線電通訊設施衛星通訊和相關太空科技(包括全球衛星定位系統)的暫時或永久的損壞,使廣大區域的電力供應中斷造成停電。強烈的太陽風暴也可能危害在高緯度、高海拔飛航的飛機與載人太空航具磁暴是極光現象發生的原因。已知最強烈的太陽風暴發生在1859年9月,稱為卡林頓事件。最強大的太陽風暴造成的損失,對現代人類的文明構成極大的威脅。

BLACK HOLE

是時空展現出重力的加速度極端強大,以至於沒有粒子,甚至電磁輻射,像是光都無法逃逸的區域。廣義相對論預測,足夠緊密的質量可以扭曲時空,形成黑洞;不可能從該區域逃離的邊界稱為事件視界 (英語:event horizon)。雖然,事件視界對穿越它的物體的命運和情況有巨大影響,但對該地區的觀測似乎未能探測到任何特徵。在許多方面,黑洞就像一個理想的黑體,它不反光。此外,彎曲時空中的量子場論預測,事件視界發出的霍金輻射,如同黑體的光譜一樣,可以用來測量與質量反比的溫度。在恆星質量的黑洞,這種溫度高達數十億K,因此基本上無法觀測。
