Could the pulverized chunks of asteroid-impacted planets provide evidence of E.T.?
"The distances and times involved can be vast, and both reduce the chance any ejecta containing life signs from another world could even reach us," Totani said."Add to that the number of phenomena in space that can destroy small objects due to heat or radiation, and the chances get even lower."
Despite the odds, however, Totani's calculations show that up to 100,000 such pieces of space dust might possibly land on Earth each year, and may be present and well-preserved within Antarctic ice or on the seafloor. Those specimens may be relatively easy to recover, compared to space dust with evidence of microbial life still floating around in space. But that latter scenario isn't impossible either. is still a complex matter," the press release states, but also points out that aerogel technologies that capture space dust exist today.
Both the paper and the press release conclude with Totani urging scientists in adjacent fields to pick up this research and explore the possibilities it may add to the search for life outside our solar system.
