Of all the objects in the cosmos, planets, stars, galaxies, none are as strange, mysterious, or powerful as black holes. Black holes are the most mind-blowing things in the universe. They can swallow a star completely intact. Black holes have these powerful jets that just spew matter out.
First discovered on paper, on the back of an envelope, some squiggles of the pen. The bizarre solution to a seemingly unsolvable equation, a mathematical enigma. Einstein himself could not accept black holes as real. People didn't even believe for many years that they existed. Nature doesn't work that way. Yet slowly, as scientists investigate black holes by observing the effect they have on their surroundings, evidence begins to mount.

The end is coming. But which cosmic catastrophe will deliver the death blow? Were the Vikings right to fear the frozen apocalypse of an endless winter? Did the Buddhists correctly predict a fiery end to life on Earth? Or will the thunderous Christian vision of Armageddon come crashing down from the stars? Which ancient prophesy do scientists believe accurately foretells our doom? And how close are we to the end of the world?
This film explores all the possibilities Apocalyptic Visions to the Future.

Stars helped create us, building and spreading the ingredients for life to develop. But there will definitely be a point in the future when, in the future when, you look up, you will no longer be able to see stars.
For billions of years, stars brought life to the universe. Now, they're dying out in a star apocalypse. What's causing the die-off, and what happens to life when the lights go out?

Beneath Yellowstone National Park, lies the biggest volcano on Earth. An eruption in the past was so big it plunged the earth into a volcanic winter that lasted years. A super-eruption would be more than millions of Hiroshima bombs going off all at once. It would be even worse than an asteroid impact: Entire cities lost beneath ash, people and animals crushed alive, power networks destroyed, sun dimmed across the globe, harvests failed, widespread famine. Could this nightmare really happen? We will use the latest scientific data to uncover the danger beneath us, as we see our planet like never before.

Curiosity over the man calling himself a messiah makes Waco the center of a media circus. FBI negotiation and rescue teams clash over the use of force. The negotiating team established contact with Koresh inside the compound.
Communication over the next 51 days included telephone exchanges with various FBI negotiators. Koresh himself had been seriously injured by a gunshot. As the standoff continued, he and his closest male associates negotiated delays, so that he could possibly write religious documents, which he said he needed to complete before his surrender. Koresh's conversations with the negotiators were dense and they also included biblical imagery. The FBI negotiators treated the situation as a hostage crisis.

The world waits as Koresh makes new promise of surrender but the FBI's controversial tactics turn the compound into an apocalyptic scene. U.S. Attorney General Janet Reno approved recommendations of FBI officials to proceed with a final advance in which the Branch Davidians would be removed from the Mount Carmel Center by force.
In an attempt to flush Koresh out of the stronghold, the FBI resorted to pumping CS gas into the compound with the aid of an M728 Combat Engineer Vehicle, which was equipped with a battering ram. In the course of the advance, the Mount Carmel Center caught fire under circumstances that remain disputed. Barricaded inside the building, 79 Branch Davidians perished in the ensuing blaze; 21 of these victims were children under the age of 16. Koresh, then 33, died of a gunshot wound to the head during the course of the fire. It is unknown whether he committed suicide or if he was killed.
