Answer question 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.
