宇宙中是否有白洞的存在?

回答1:

白洞
白洞 (white hole)

黑洞就像宇宙中的一个无底深渊,物质一旦掉进去,就再也逃不出来。根据我们熟悉的“矛盾”的观点,科学家们大胆地猜想到:宇宙中会不会也同时存在一种物质只出不进的“泉”呢?并给它取了个同黑洞相反的名字,叫“白洞”。

科学家们猜想:白洞也有一个与黑洞类似的封闭的边界,但与黑洞不同的是,白洞内部的物质和各种辐射只能经边界向边界外部运动,而白洞外部的物质和辐射却不能进入其内部。形象地说,白洞好像一个不断向外喷射物质和能量的源泉,它向外界提供物质和能量,却不吸收外部的物质和能量。

白洞到目前为止,还仅仅是科学家的猜想,还没有观察到任何能表明白洞可能存在的证据。在理论研究上也还没有重大突破。不过,最新的研究可能会得出一个令人兴奋的结论,即:“白洞”很可能就是“黑洞”本身!也就是说黑洞在这一端吸收物质,而在另一端则喷射物质,就像一个巨大的时空隧道。

科学家们最近证明了黑洞其实有可能向外发射能量。而根据现代物理理论,能量和质量是可以互相转化的。这就从理论上预言了“黑洞、白洞一体化”的可能。

要彻底弄清楚黑洞和白洞的奥秘,现在还为时过早。但是,科学家们每前进一点,所取得的成绩都让人激动不已。我们相信,打开宇宙之谜大门的钥匙就藏在黑洞和白洞神秘的身后。

广义相对论所预言的一种与黑洞相反的特殊天体。和黑洞类似,它也有一个封闭的边界。聚集在白洞内部的物质,只可以向外运动,而不能向内部运动。因此,白洞可以向外部区域提供物质和能量,但不能吸收外部区域的任何物质和辐射。白洞是一个强引力源,其外部引力性质与黑洞相同。白洞可以把它周围的物质吸积到边界上形成物质层。白洞学说主要用来解释一些高能天体现象。

有人认为,类星体的核心就可能是一个白洞。当白洞内中心点附近所聚集的超密态物质向外喷射时,就会同它周围的物质发生猛烈碰撞,而释放出巨大的能量。因此,有些X射线、宇宙线、射电爆发、 射电双源等现象,可能与白洞的这种效应有关。白洞目前还只是一种理论模型,尚未被观测所证实。

回答2:

你先说一下什么是白洞吧.
黑洞是一个由极高密度物质形成的空间,极大的引力使光子无法运动出来,才形成了所谓的黑洞。

回答3:

有,白洞跟黑洞相反,不断喷出物质
另外,白洞是有死亡的黑洞变来的

回答4:

没有

回答5:

当然有白洞,这只是一个定义,你想怎么定就怎么定
