9月的剧集-黑洞和黑魔法（Black Holes and Black Magic）星期六9月8日，下午1:00 BBC两首（短）记录：04（？）BBC四月（长版）黑洞黑洞曾被认为是宇宙中的怪物，吞噬了它们周围的一切疯狂的宇宙盛宴。但是现在天文学家认为，黑洞可能不是太空威胁，而是星系形成的基础。黑洞是太空中引力非常强的区域，甚至连光也无法逃逸，因此看不到它们。但是我们可以看到被这些大型宇宙真空吸尘器吸收的东西。接近黑洞的任何物体都首先会因其巨大的重力而被撕开，然后形成一个扁平的旋转盘，盘旋成螺旋状进入该黑洞。随着这些碎片越来越靠近黑洞的嘴，它会加速，并且钻头开始一起粉碎。材料由于这种摩擦而变热（这与双手搓热以使其加热时的效果相同）。当这在黑洞周围发生时，会发出X射线，我们可以检测到。如果黑洞确实很大并且在其圆盘上有很多碎片，那么它可以显示自己是宇宙中最亮的物体之一-类星体。黑洞有两种主要类型-恒星和超大质量。恒星大小的黑洞是大量已爆炸的恒星的残留。对我们而言，最接近的是1971年发现的名为Cygnus X-1的双星系统的一部分。它位于天鹅座星座中，也被称为北十字星。它'?据估计，我们的星系包含数百万个此类恒星黑洞。另一方面，超大质量黑洞的初始质量可能是太阳的百万倍。现在认为它们可能潜伏在每个星系的中心，并成为星系演化方式不可或缺的一部分。也可能存在其他类型的黑洞，例如微型黑洞，其体积（小于体积）比原子小，但与整个山脉一样大（物质量）。甚至在恒星和超大质量变星之间的中等大小的黑洞。可能有诸如“白洞”之类的东西，与“黑洞”相对，将物质和能量喷入宇宙。然而，这只是仍在等待解决的宇宙奥秘中的另一个。初始质量是太阳的数百万倍。现在认为它们可能潜伏在每个星系的中心，并成为星系演化方式不可或缺的一部分。也可能存在其他类型的黑洞，例如微型黑洞，其体积（小于体积）比原子小，但与整个山脉一样大（物质量）。甚至在恒星和超大质量变星之间的中等大小的黑洞。可能有诸如“白洞”之类的东西，与“黑洞”相对，将物质和能量喷入宇宙。然而，这只是仍在等待解决的宇宙奥秘中的另一个。初始质量是太阳的数百万倍。现在认为它们可能潜伏在每个星系的中心，并成为星系演化方式不可或缺的一部分。也可能存在其他类型的黑洞，例如微型黑洞，其体积（小于体积）比原子小，但与整个山脉一样大（物质量）。甚至在恒星和超大质量变星之间的中等大小的黑洞。可能有诸如“白洞”之类的东西，与“黑洞”相对，将物质和能量喷入宇宙。然而，这只是仍在等待解决的宇宙奥秘中的另一个。例如微型黑洞，其体积（小于原子），但与整个山峰一样大（物质量）。甚至在恒星和超大质量变星之间的中等大小的黑洞。可能有诸如“白洞”之类的东西，与“黑洞”相对，将物质和能量喷入宇宙。然而，这只是仍在等待解决的宇宙奥秘中的另一个。例如微型黑洞，其体积（小于原子），但与整个山峰一样大（物质量）。甚至在恒星和超大质量变星之间的中等大小的黑洞。可能有诸如“白洞”之类的东西，与“黑洞”相对，将物质和能量喷入宇宙。然而，这只是仍在等待解决的宇宙奥秘中的另一个。September's Episode - Black Holes and Black MagicSaturday 08 September, 1.00pm BBC Two (short)Recorded: 04 (?) September BBC Four (long version)Black HolesBlack holes were once thought to be the monsters of the Universe, devouring everything around them in a frenzied cosmic feast. But now astronomers think that rather than being a space menace, black holes may be fundamental to the creation of galaxies.Black holes are regions of space where gravity is so strong that not even light can escape, making them impossible to see. But we can see the stuff that is being sucked in to these massive cosmic vacuum cleaners. Anything that approaches a black hole is first torn apart by its immense gravitational force and then forms a flat rotating disc that spirals into the hole.As this debris gets closer and closer to the mouth of the black hole it speeds up and the bits start to smash together. The material heats up due to this friction [this is the same effect as when you rub your hands together to warm them up]. When this happens around a black hole, X-rays are given off which we can detect. If the black hole is really large and has lots of debris in its disc, then it can reveal itself as one of the brightest objects in the Universe - a quasar.There are two main types of black hole - stellar and supermassive. Stellar sized black holes are the remnants of massive dead stars that have imploded. The nearest one to us is part of a binary system called Cygnus X-1, discovered in 1971. It is in the constellation of Cygnus, also known as the Northern Cross. It's estimated that our galaxy contains millions of these stellar black holes. Supermassive black holes, on the other hand, can have initial masses millions of times that of the Sun. It's now thought that they may lurk in the centre of every galaxy and be integral to the way galaxies evolve. There might also be other types of black holes, such as mini black holes, smaller (in volume) than atoms but as massive (in amount of matter) as whole mountains. Or even middle-sized black holes, mid-way between the stellar and supermassive variety. It's possible that there could be such things as 'white holes', the opposite of black holes, spewing out matter and energy into the Universe. However, this is just another of the cosmic mysteries still awaiting a solution.
