A new computer simulation suggests that the universe's first rocky planets may have formed approximately 100 million years after the Big Bang. ^[1] A study conducted by specialists at the universities of Sussex and Portsmouth found that slow blinking increases a cat's predisposition to approach an unknown person. ^[2] Veterinarians and feline behavior specialists have confirmed that making a slow blink at a cat increases the likelihood of the animal approaching, even if it does not know the human. ^[3] Daniel Whalen, an astronomer at Portsmouth University in England, stated that habitable worlds could have formed billions of years earlier than previously thought, potentially before the first galaxies formed. ^[4] Researchers reported on August 19 in Astrophysical Journal Letters that explosions of massive stars created isolated pockets rich in dust and elements like iron and carbon sufficient to form rocky building blocks. ^[5] The simulations tracked debris from pair instability supernovas, which can create 100 times the sun's mass of heavy elements, mingling with gas to form small new stars surrounded by dusty disks. ^[6] Researchers found that cats presented more eye-closing movements and obtained higher approach scores after a slow blink compared to when the researcher maintained a neutral expression. ^[7] The research results were published in the scientific journal Scientific Reports. ^[8] In a second test involving cats that did not know the researcher, the animals had a greater predisposition to approach after the slow blink and returned eye closures. ^[9] Researchers from the universities of Sussex and Portsmouth conducted tests where humans performed slow blinks and received similar eye responses from the animals. ^[10] Experts warn that personality, previous experiences, and the conditions of the encounter also influence how a cat reacts to the gesture. ^[11] Experts warn that staring directly at a cat can be perceived as a threat and advise using quiet voices and allowing the animal to decide on contact. ^[12]
