In physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time in the future, until ...

2003年5月，美国 新罕布什尔 达特茅斯大学 的物理学家罗伯特·卡德威尔提出了这种宇宙“壮烈”死亡的观点。 卡德威尔告诉英国《新科学家》杂志说，“直到2003年3月前，我们还认为宇宙可能有两种结局：向内收缩挤压崩溃，或者无限地膨胀，密度无限地稀释，我们认为可能还存在第三种可能——‘大撕裂’（Big Rip，相对于 宇宙起源 ‘大爆炸’Big Bang）。 宇宙将在数百数千亿年后毁于更为可怕的“大撕裂”。 卡德维尔称，到时，由宇宙暗能量质变生成的“幻能”将撕裂宇宙中的一切物 …

Feb 26, 2024 · First come the clusters, with their galaxies pulled away from each other. Then, the galaxies dissolve. Then the star systems and the planets. And then atoms themselves. Eventually, space - time is...

大撕裂 是一種 宇宙論 假說，在2003年首度被發佈，內容牽涉 宇宙的終極命運。 假說認為宇宙中的物質，從 恆星 和 星系 到原子和次原子粒子，乃至 时空 本身，都会在未來有限的時間內因 宇宙加速膨脹 而逐漸被撕裂，直到粒子间距无限增大。 根据宇宙学标准模型， 宇宙標度因子 在未來有限的時間內會變得無限大，在宇宙常数占主导地位的未来，更会呈指数级增长。 不过，这种膨胀在每时刻都相似（因此有指数律——在相同时间间隔内，局部体积的膨胀次数相同，特点是 哈 …

Jul 3, 2015 · For a Big Rip to occur, dark energy must win in its battle with gravity to such a point where it can rip apart individual atoms. He began by looking at the stickiness of the universe -- or how...

Dec 16, 2018 · Disconzi’s hypothesis says that a Big Rip can occur when dark energy will become stronger than gravity, reaching a point when it can rip apart single atoms. The professor’s model shows that as...

In physical cosmology, the Big Rip is a theory which describes the ultimate fate of the universe. According to this theory, everything in the universe, even spacetime itself will be torn apart by the expansion of the universe until distances between particles will become infinite.

Feb 20, 2004 · This animation demonstrates that if Dark Energy became stronger than Einstein's predictions, the universe would be torn apart. This would lead to a "Big Rip" where the universe ultimately expands so violently that the galaxies, the stars, planets, and finally atoms would come unglued in a catastrophic end of time.

May 21, 2024 · The "big rip" is one theoretical way in which the universe may come to an end, depending on its total density, which is difficult to determine. Observations by astronomers and physicists show that the universe, as a whole, continues to expand and that objects within it, such as galaxies, are moving away from each other at an increasing rate.

Abstract: The big rip, the little rip and the little sibling of the big rip are cosmological doomsdays predicted by some phantom dark-energy models that could describe the future evolution of our universe. When the universe evolves towards either of …
