• Clara Sousa-Silva, a quantum astrochemist, said during a segment in BBC’s online presentation “Ideas”: “We have been sending (television and radio) signals for the past 100 years, and those signals have gone into space and traveled at the speed of light and by now have reached hundreds of stars and hundreds of planets around them” There is a big chance that these aliens now know a lot about human origins, culture and history thanks to all the “material” that we’ve been sending them for years. “If there was an alien civilization then they would have heard the first BBC broadcasts… and have a rough idea of how our humanity works,” said Sousa-Silva.
• Sousa-Silva also said that some prominent scientists actually think that humans are sharing too much to the galaxy, especially since we know nothing about them. “Aliens may not be very kind so we shouldn’t be giving them our position.”
• But even without these television and radio signals, the Earth has a biosphere that basically gives any alien civilization an idea as to what type of species thrive in it. Aliens would be able to use a powerful prism to filter the white lights of our galaxy and separate the colors of the rainbow to determine our position in the universe. The shadows would tell them that this is indeed a lively planet filled with vast oceans and organic life forms.
• By the same principle of using radio signals to find earth, the scientist also believes that we can use alien biospheres to determine if there are extraterrestrials that actually exist in the universe. “At MIT, I develop the tools that try to decipher these potential alien biospheres. Those tools are how I will be listening in to alien messages. Until then I will try to find signs of life from signals aliens didn’t even mean to create,” Sousa-Silva said.
If you think that watching your favorite sitcom on Netflix or cable TV is just limited to entertainment, think again. We are also unknowingly sending vast signals to the universe and pretty much letting any possible aliens out in space know how to find us.
In fact, we’ve been sending out so many radio signals for the past 100 years that even if we turn off all satellites today, extraterrestrials from outer space will still be able to find us, Clara Sousa-Silva, a quantum astrochemist, said during a segment in BBC’s “Ideas.”
“We have been sending signals for the past 100 years and those signals have gone into space and traveled at the speed of light and by now have reached hundreds of stars and hundreds of planets around them,” Sousa-Silva, who is doing her post-doctorate degree in MIT and is a Ph.D. holder from the University College London, said.
The astrochemist said that the signals are now strong enough to be detected should there be alien civilizations out in the universe. Aside from this, there is also a big chance that these aliens now know a lot about human origins, culture and history thanks to all the “material” that we’ve been sending them for years.
“If there was an alien civilization then they would have heard the first BBC broadcasts and now they would have seen many, many years of Coronation Street and have a rough idea of how our humanity works,” she said.
Sousa-Silva also said that some prominent scientists actually think that it’s silly how humans are sharing too much to the galaxy especially since we know nothing about them.
