How To Destroy The Universe
Kurzgesagt – In a Nutshell
12 min, 33 sec
An exploration of the universe's potential ends: Heat Death, Big Rip, and Big Crunch, and an acknowledgment of the support from the Human Era Calendar sales.
Summary
- The video discusses three scenarios for the universe's end: Heat Death with constant dark energy, Big Rip with increasing dark energy, and Big Crunch with decreasing dark energy.
- In the Heat Death scenario, dark energy causes the universe to expand forever, leading to a cold, featureless state.
- In the Big Rip scenario, dark energy grows stronger, tearing apart galaxies, stars, and eventually the fabric of reality itself.
- In the Big Crunch scenario, gravity prevails, leading to the universe collapsing into a hot, dense state, potentially creating a new universe.
- The video ends with a tribute to the Human Era Calendar, which has been instrumental in supporting Kurzgesagt's mission.
Chapter 1
Introduction to the video and thanks to supporters through calendar sales.
- The video is made possible by the sale of the limited edition Kurzgesagt calendar.
- The new 12,024 calendar is described as the most spectacular yet, and viewers are invited to own a piece of Kurzgesagt history.
Chapter 2
The universe's fate is discussed as a conflict between matter and dark energy.
- The universe, born from the Big Bang, is expanding due to empty space being created between galaxies.
- This expansion could either continue forever or stop, depending on the struggle between matter (gravity) and dark energy.
Chapter 3
Exploration of the Heat Death scenario with constant dark energy.
- If dark energy's strength remains constant, it will eventually cause an exponential expansion of the universe.
- Matter can keep local structures like galaxy groups together, but the universe will become dark and cold as stars die out.
- Over time, the universe will dissolve into isolated particles, leading to a featureless, cold, eternally expanding universe.
Chapter 4
Exploration of the Big Rip scenario with increasing dark energy.
- An increase in dark energy's strength over time would lead to the Big Rip, tearing apart all matter and the fabric of reality.
- This would start by pushing galaxies apart, then stars, and eventually atoms, concluding with a cataclysmic end to the universe.
Chapter 5
Exploration of the Big Crunch scenario with decreasing dark energy.
- If dark energy weakens over time, gravity will pull everything back together, leading to the universe collapsing in the Big Crunch.
- Galaxies and stars will merge into a hot plasma, and the universe could collapse into a singularity or bounce back into a new expansion.
Chapter 6
The most probable universe end scenario and a final word on the Human Era Calendar's impact.
- Most scientists believe in the Heat Death scenario due to constant dark energy, suggesting a long, albeit cold, future for the universe.
- The video concludes with the hope of a prolonged existence for humanity and the universe to explore and possibly extend consciousness.
Chapter 7
The significance of the Human Era Calendar to Kurzgesagt's growth and mission.
- The Human Era Calendar started as a passion project and now supports the Kurzgesagt team and video production.
- The calendar represents Kurzgesagt's worldview and has enabled the team to release high-quality science videos for free.
