Topics include : planets, planet formation ; stars, the sun, " normal " stars, star formation ; stellar evolution, supernovae, compact objects ( white dwarfs, neutron stars, and black holes ), plusars, binary x - ray sources ; star clusters, globular and open clusters ; interstellar medium, gas, dust, magnetic fields, cosmic rays ; distance ladder ; galaxies, normal and active galaxies, jets ; gravitational lensing ; large scaling structure ; newtonian cosmology, dynamical expansion and thermal history of the universe ; cosmic microwave background radiation ; big - bang nucleosynthesis
課程的主題包含了：行星、行星形成；恆星、太陽、正常的恆星、恆星形成；恆星演化、超新星、緻密天體（白矮星、中子星及黑洞） 、波霎、雙x -射線源；星團、球狀及疏散星團；星際介質、氣體、塵埃、磁場、宇宙射線；距離階梯；星系、正常及活躍星系、噴流；重力透鏡；大尺度結構；牛頓宇宙學、宇宙的動力膨脹及溫度發展歷史；宇宙背景微波輻射；大霹靂核合成。And whereas microwaves, radio waves and light ? all forms of electromagnetic radiation ? are easily absorbed by dust and gas, leaving much of the universe hidden, gravitational waves penetrate anything in their path
盡管由於，微波，無線電波，和廣播等一切形式的電磁輻射，都很容易被塵埃和氣體吸收，所以我們看到的只是隱藏在黑暗中的宇宙，然而重力波卻能在穿透一切讓我們可以看清它的軌跡。The equilibrium thermal radiation in a flat space - time or a curved space - time behaves like planck black spectrum represented with coordinate quantities. we regard the fact that the radiation from a thermal equilibrium system shows planck black spectrum as a basic physics law, from which it is demonstrated that the transitivity of clock rate synchronization is equivalent to the zeroth law of thermodynamics. the condition of clock rate synchronization is weaker than that constructing simultaneity surfaces. in the space - time satisfying the condition of clock rate synchronization, the zeroth law of thermodynamics is valid. on the other hand, in the space - time where the zeroth law is valid, one can define an identical clock rate
平直或彎曲時空中的平衡熱輻射，表現出用坐標量表示的普朗克黑體譜.把熱平衡系統的輻射具有普朗克黑體譜作為一條基本的物理規律，以此為基礎，論證鐘速同步的傳遞性等價于熱力學第零定律.鐘速同步的條件比建立同時面的條件要弱.滿足這一條件的時空，熱力學第零定律在其中成立.第零定律成立的時空，一定可以定義統一的鐘速They found two events showing the shortening of pulsating cycle and decaying of radiations intensity. the signatures matched theories of what scientists would predict to see. when matter is falling so close to the event horizon, it will be circling the black hole with increasing speed and its light will rapidly dim as it is stretched by gravity to ever - longer wavelengths
研究人員分析了極大量來自緻密天體天鵝座xr - 1的紫外線輻射，發現其中兩組數據顯示，輻射脈沖的周期隨時間縮短，而其強度則隨時間衰減至消失，這現象與一些物質在接近黑洞視界時繞著黑洞急促旋轉，放出的輻射因為重力紅移而衰減的情況相符。分享友人
