Question

from the movie alien contact. if we receive a message from across our milky way galaxy, when did it get sent?
2 days ago
billion of years ago
10 years ago
100,000 years ago
in the movie alien contact, the most extreme form of life discovered thus far was found
on the moon europa
on the moon titan
on earth in lava vent tubes on the ocean floor
on earth in a cave

Explanation:

First Question (When did the message get sent?):

In the context of the Milky Way galaxy, the distance across it is vast (about 100,000 light - years in diameter). Light takes time to travel, so a message from across the galaxy would have been sent a long time ago. Among the options, 100,000 years ago aligns with the time it would take for a signal to travel across the Milky Way (considering the speed of light and the galaxy's size). The other options (2 days, 10 years, or a billion years) don't match the scale of the Milky Way's size and light - travel time.

In the movie "Contact", the most extreme form of life (extremophiles) was found on Earth, specifically in lava vent tubes on the ocean floor. The options about Europa (a moon of Jupiter) and Titan (a moon of Saturn) are not correct in the context of this movie's plot for the "most extreme form of life" discovery. The option about a cave on Earth is also incorrect as it was the ocean - floor lava vents.

Answer:

D. 100,000 years ago (assuming the options are labeled A: 2 days ago, B: billion of years ago, C: 10 years ago, D: 100,000 years ago)

Second Question (Where was the extreme life found?):
