Quantum researchers have managed to simulate the reversal of time at the quantum scale, using IBM’s quantum computers. Although the effect is simulated, the implication of this experiment is that the arrow of time doesn’t necessarily have to flow in one direction, but can be reversed, allowing what once was
Interstellar Interloper ‘Oumuamua may have been an Extraterrestrial Spacecraft, according to Harvard Astronomers
A controversial paper has been published by astronomers at Harvard University that suggests that that the odd behavior being exhibited by the interstellar object known as ‘Oumuamua might actually be an artificial object that was built by an extraterrestrial civilization in the form of a solar-powered "lightsail".
A recent analysis of the fossils of ancient microorganisms from deep within Earth’s past have unveiled the presence of a surprising amount of biodiversity that flourished roughly 3.4 billion years ago, when the Earth was still a very young planet. The variety of metabolic processes that these early microorganisms used suggests that they needed time to evolve the diversity that the researchers discovered, meaning that life on Earth had to have started much, much earlier. And if life on Earth took hold that quickly in its history, what would prevent the multitude of other planets we’re discovering across the universe from forming their own lifeforms?
