Mars is on the outer boundary of our solar system’s habitable zone, meaning it’s a region where liquid water could form and exist for long periods of time. We know that water is the source of life on Earth, but could it also point to the same on Mars?

Now cosmology inches towards the next paradigm shift: One of the most mind-boggling discoveries of modernity is that the fabric of spacetime is emergent from something beneath it. “[O]ne new theory says that Dark Matter may be ordinary matter in a parallel universe. If a galaxy is hovering above in another dimension, we would not be able to see it. It would be invisible, yet we would feel its gravity. Hence, it might explain Dark Matter,” in the words of Michio Kaku as an opening quote to this article. #DarkMatter #DarkEnergy #QuantumGravity #ComputationalPhysics #MTheory #DTheoryofTime #OmegaSingularity #pancomputationalism #multiverse #ontology
Dark Matter could be ordinary matter in the “probabilistic space” and “phase space” (5th and 6th dimensions of M-theory), possibly with “dark star systems” and life, imperceptible to us at our current level of development. In turn, Dark Energy could be a.
Definitely watch it for the sense of isolation when our technology bubble evaporates and for the “comb jelly” space alien.
The cosmos is likely teeming with intelligent civilizations who have sent untold numbers of space probes out into interstellar space, says Harvard University astronomer Avi Loeb is this week’s Cosmic Controversy guest. This episode lives up to the podcast’s branding! Episode 37 — Is Oumuamua, Our Solar System’s 1st Identified Interstellar Asteroid, Actually An Alien Probe?
Did an alien lightsail traverse our solar system in 2017? Harvard University astronomer Avi Loeb thinks so. In today’s episode, I welcome Loeb to discuss his bestselling book — “Extraterrestrial: The First Sign of Intelligent Life Beyond Earth.” We chat about why he thinks this object, Oumuamua, is likely to be artificial and why the scientific community at large remains so unreceptive to progressive scientific thinking when it comes to the subject of extraterrestrial intelligence.
Perseverance will scour mud and clay in Jezero’s river delta and shorelines for signs of microbe communities.
For noted theoretical physicist Frank Wilczek, finding aliens is a matter of figuring out what exactly we are looking for. To detect other space civilizations, we need to search for the specific effects they might be having on their worlds, argues the Nobel laureate in a new proposal.
Writing in the Wall Street Journal, Wilczek says that it’s a real challenge to figure out which among the over 4000 exoplanets that we found so far outside of our solar system might host extraterrestrial life. The classic way of listening for space signals is insufficient and inefficient, says the scientist. What might really help are new developments in exoplanetary astronomy that can allow us to get much more precise information about faraway space objects.
In particular, there are two ways we should focus our attention to turn the odds of finding alien life in our favor, argues the physicist.
If our universe is a bubble that inflated inside a larger multiverse, it might bear scars from collisions with nearby bubbles.
What lies beyond all we can see? The question may seem unanswerable. Nevertheless, some cosmologists have a response: Our universe is a swelling bubble. Outside it, more bubble universes exist, all immersed in an eternally expanding and energized sea — the multiverse.
The idea is polarizing. Some physicists embrace the multiverse to explain why our bubble looks so special (only certain bubbles can host life), while others reject the theory for making no testable predictions (since it predicts all conceivable universes). But some researchers expect that they just haven’t been clever enough to work out the precise consequences of the theory yet.
