Let's reproduce the calculations from Interstellar

Summary

This video explores the scientific accuracy of 'Interstellar', analyzing the ship's speed, artificial gravity, and black hole depictions. It delves into wormhole geometry, time dilation near a black hole, and the film's portrayal of gravitational anomalies. The video also discusses the theoretical physics behind the movie's climax, including the Tesseract and the potential for quantum gravity to save humanity.

Takeaways

• 🚀 *Interstellar* explores the realism of its scientific concepts, such as black holes and wormholes, with calculations to verify their accuracy.
• 🛰️ The ship in *Interstellar* travels at approximately 70,000 km/h, a speed feasible with advanced technology, taking two years to reach Saturn.
• 🌍 Artificial gravity is created on the spaceship *Endurance* through centrifugal force, with realistic dimensions of about 60 meters in diameter.
• 🌀 The movie's portrayal of a wormhole as a three-dimensional tunnel connecting two slices of space is consistent with theoretical physics.
• 🌊 On Miller’s planet, 1 km high waves result from tidal forces due to its proximity to the supermassive black hole Gargantua, though the time dilation portrayed is exaggerated.
• ⏳ Time dilation near Gargantua leads to one hour on Miller’s planet equating to seven years on Earth, achievable with a rapidly rotating black hole.
• 🌌 Gargantua’s visual effects include a plasma accretion disk with gravitational lensing and Doppler effects, though some aspects were altered for cinematic purposes.
• 🧑‍🔬 Professor Brand's equation suggests that gravitational anomalies may be caused by fields in a larger universe with extra dimensions.
• 🕳️ Cooper survives falling into the black hole due to a theoretical gentle singularity, and enters a four-dimensional tesseract created by advanced beings.
• 🏟️ The *Cooper Station* space habitat likely has a diameter between 50 to 100 meters, based on a baseball trajectory used to calculate its rotation and gravity.

Q & A

What is the main theme of the video 'Interstellar'?

The video discusses the scientific accuracy and concepts presented in the movie 'Interstellar', such as black holes, wormholes, and the behavior of time and space.

What is the estimated speed of the ship in 'Interstellar'?

The estimated speed of the ship in 'Interstellar' is around 70,000 km/h, calculated by dividing the distance of approximately 1.3 billion km by 2 years of travel time.

How does the artificial gravity system work in the ship Endurance?

The artificial gravity system in the ship Endurance works by using a rotating wheel, which creates a centrifugal force that pushes the characters against its outer walls, simulating gravity.

What is a wormhole and how does it appear in the movie 'Interstellar'?

A wormhole is a theoretical 'shortcut' through spacetime, connecting two distant points in the universe. In the movie, it appears as a three-dimensional tube connecting two celestial spheres.

What is the concept of time dilation as depicted in 'Interstellar'?

Time dilation in 'Interstellar' refers to the difference in the passage of time between two observers due to differences in their relative motion or gravitational fields. On Miller's planet, one hour corresponds to seven years on Earth.

How are the massive waves on Miller's planet explained?

The massive waves on Miller's planet are explained as tidal forces caused by the close proximity to the black hole Gargantua, which distorts the planet and creates immense waves.

What is the significance of the black hole Gargantua in 'Interstellar'?

Gargantua is a supermassive black hole with a strong gravitational pull that affects the time dilation experienced by the characters and the extreme tidal forces on nearby planets.

How does the Tesseract, a four-dimensional object, play a role in the movie?

The Tesseract in 'Interstellar' is a four-dimensional space that allows Cooper to interact with his past and communicate with his daughter Murphy, providing a means to send crucial data.

What is the role of the character Cooper in the movie 'Interstellar'?

Cooper, a former NASA pilot, plays the protagonist who embarks on an interstellar journey to find a new home for humanity and eventually interacts with a higher dimension to influence past events.

What scientific theories are explored in the movie's depiction of the universe?

The movie explores theories such as general relativity, quantum mechanics, and the possibility of extra dimensions, as well as the effects of black holes on time and space.

How does the movie 'Interstellar' visualize the scientific concept of gravitational anomalies?

Gravitational anomalies in 'Interstellar' are visualized as strange occurrences that guide characters to secret locations and are later explained as being influenced by higher-dimensional fields.
