NASA's 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 magnify objects that are otherwise too faint. The video also critiques the scientific inaccuracies in the movie 'Gravity', highlighting the differences between Hollywood's portrayal and real-life physics.

What is the primary technique used by NASA to detect distant galaxies?

• Radio wave analysis

• Ultraviolet imaging

• Gravitational lensing

• Infrared scanning

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

• To map the Milky Way galaxy

• To observe distant galaxies and understand the early universe

• To study the sun's corona

• To explore the surface of Mars

Which telescopes are used in the Frontier Fields program?

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

• Spitzer, Kepler, and Chandra X-ray Observatory

• Hubble, Spitzer, and Chandra X-ray Observatory

• Kepler, James Webb, and Hubble

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

• The size of the Earth

• The color of the spacesuits

• The proximity of space stations

• The depiction of a black hole

Why would Sandra Bullock's tears not fall off her face in space?

• Due to the high temperature in space

• Because of surface tension in a weightless environment

• Because of the absence of gravity

• Due to the lack of air pressure
