Oumuamua is not made of nitrogen, according to Harvard astrophysicists

What was one of the initial theories about Oumuamua's nature?

• It is a new type of comet.

• It is a fragment of a destroyed planet.

• It is a black hole.

• It is a piece of alien technology.

What does the nitrogen iceberg theory suggest about Oumuamua's composition?

• It is made of pure hydrogen.

• It is composed of frozen nitrogen.

• It is a metallic asteroid.

• It is a water-based comet.

How does the nitrogen iceberg theory explain Oumuamua's flat shape?

• It was formed in a supernova explosion.

• It was shaped by gravitational forces.

• It was flattened by cosmic radiation.

• It was compressed by a black hole.

What is the main argument against the nitrogen iceberg theory?

• There are not enough Pluto-like exoplanets.

• Oumuamua is too large to be made of nitrogen.

• Oumuamua's speed is too slow.

• Nitrogen is too common in the universe.

What did Stephen Dash argue about the estimates used by Harvard astrophysicists?

• They ignored the possibility of alien technology.

• They correctly estimated the number of exoplanets.

• They overestimated the amount of nitrogen required.

• They underestimated the number of similar objects.
