Questão 1705154

Answer questions 06 and 07 according to the text below.

A scientific paper led by two researchers at Harvard University made a splash this week by claiming that a cigar-shaped rock zooming through our solar system may have been sent by aliens. Oumuamua, Hawaiian for "messenger" or "scout", was first viewed by telescopes in October 2017. It is the first interstellar object known to enter our solar system.

"There is an unexplained phenomena: the excess acceleration of Oumuamua, which we show may be explained by the force of radiation pressure from the sun. However this requires the body to have a very large surface and be very thin, which is not encountered in nature", co-author and Harvard astrophysicist Shmuel Bialy said.

Their suggestion of an alien force at work went viral. But other astronomy experts aren't buying it

Asked if he believed the hypothesis he put forward, Bialy pointed: "I wouldn't say I 'believe' it is sent by aliens, as I am a scientist, and not a believer, I rely on evidence to put forward possible physical explanation for observed phenomena."

Their paper was accepted for publication in the Astrophysical Journal Letters.
