NASAs new frontier and the Trouble with Gravity

The video discusses NASA's Frontier Fields program, which uses gravitational lensing to study distant galaxies. It explains how this technique allows astronomers to see and measure galaxies that are otherwise too faint. The video also critiques the scientific inaccuracies in the movie 'Gravity', highlighting issues with physics and space travel depicted in the film.

What is the main challenge of using gravitational lensing to observe distant galaxies?

• It distorts the light, making it hard to measure true size and distance.

• It requires multiple telescopes.

• It is only effective for nearby galaxies.

• It can only be used during the day.

What is the primary goal of NASA's Frontier Fields program?

• To develop new space travel technologies.

• To use gravitational lensing to observe distant galaxies and understand the universe's formation.

• To study the sun's corona.

• To explore the surface of Mars.

Which telescopes are used in the Frontier Fields program?

• Spitzer, Kepler, and Chandra X-ray Observatory

• James Webb, Hubble, and Chandra X-ray Observatory

• Hubble, Kepler, and James Webb

• Hubble, Spitzer, and Chandra X-ray Observatory

What is one of the inaccuracies pointed out in the movie 'Gravity'?

• The realistic portrayal of space debris.

• The accurate distance between the Hubble and ISS.

• The correct depiction of zero-gravity tears.

• The depiction of astronauts wearing casual clothes under spacesuits.

Why is it unrealistic for the Hubble, ISS, and a Chinese space station to be within sight of each other as shown in 'Gravity'?

• They are not in space.

• They orbit at significantly different altitudes.

• They are on different continents.

• They are part of different space agencies.
