Newest alien news3/16/2023 Speeds are limited to the speed of light, which is around 300,000 km per second. The vast volume of the universe makes it very difficult to achieve interstellar travel, receive signals, or communicate with any potential far-off lifeforms (at least according to the laws of physics as we know them). While I believe life will almost certainly exist among the trillions of planets in the universe – the sheer scale of the universe is a problem. On top of that, we’re not even sure sharks exist and, if they do, what they would look like or how they would behave. If the Milky Way is considered equivalent to the Earth’s oceans, the sum total of our decades of searching is like taking a random swimming pool worth of water out of the ocean to search for a shark. But after decades of many teams of experts using powerful telescopes, we still haven’t covered much territory. On and off over the past decade, I’ve used radio telescopes to perform wide ranging experiments to search for technosignatures – signs of technological civilisations on planets elsewhere in our galaxy (the Milky Way). So the search for extra-terrestrial life is a legitimate pursuit, subject to the same burden of evidence that applies to all science. But the leap to aliens requires far more substantial and direct evidence – incredible evidence – that can be widely scrutinised using the tools of science.Īfter all, the existence of life elsewhere in the universe is a fascinating question of science and society. There is no doubt unexplained phenomena have been observed, such as in footage obtained by navy pilots (above) showing fast moving airborne objects. The hearings did include closed classified sessions that presumably dealt with more sensitive security information. None of the public testimony went any way towards supporting a conclusion that alien spacecraft have crashed on, or visited, Earth. Since the technology requires both quantum and classical signals, scientists could look for such simultaneous signals to identify any alien quantum missives.Footage of three UAPs from US Navy pilots. One potential type of communication to search for is quantum teleportation, in which the properties of a distant particle can be transferred to another ( SN: 7/7/17). X-ray photons could more than traverse the Milky Way, potentially traveling hundreds of thousands of light-years or even more, the researchers found.īased on the findings, Berera and Calderón Figueroa considered strategies to search for E.T.’s quantum dispatches. So Berera and theoretical physicist Jaime Calderón Figueroa, both of the University of Edinburgh, calculated how far light - in particular, X-rays - could travel unscathed through interstellar space. Since the average density of matter in space is much less than on Earth, particles could be expected to travel farther before succumbing to decoherence. “Quantum states you generally think of as very delicate, and if there’s any kind of external interaction, you kind of destroy that state,” Berera says. A major obstacle to quantum communication is decoherence, in which a quantum particle loses its quantumness as it interacts with its surroundings.
