Researchers have discovered lithium hidden in pyrite within ancient shale rocks—an unexpected find that could reshape how we source this critical battery material. It raises the possibility of extracting lithium from existing waste, reducing the need for new mining.

The Lyrid meteor shower will soon hit its peak. Here's how to spot it, including by using the New Scientist stargazing companion

It's vital that your conference attendees know the speakers' past credibility to judge their current credibility. All you have to do is be honest.

In 1934, a Soviet physicist named Pavel Cherenkov shone gamma rays into a bottle of water and noticed a faint blue glow. So had others before him. They all shrugged and moved on. Cherenkov didn't. What he found — by refusing to dismiss something he didn't understand — turned into one of the most useful phenomena in modern physics.

It's obvious that Earth is a planet. It's obvious that the Sun is a star. But for substellar objects like brown dwarfs, it's not so clear. Researchers are using the JWST to find a stronger dividing line between star and planet that depends on how they formed.

A pair of dwarf galaxies in the giant Virgo Cluster show what can happen when these stellar cities interact. Scientists at the University of Michigan focused the James Webb Space Telescope (JWST) onto the galaxies NGC 4486B and UCD736 and found each of them sporting "overmassive" black holes at or near their hearts. Those supermassive black holes comprise a large fraction of each galaxy's mass.

On the relationship between the pointless cosmos and purposeful living organisms.

I am a firm believer in miracles—a confession that will be immediately off-putting to readers of Skeptic. Below I will offer a definition of miracles and attempt to justify belief in them, but for the moment I will focus on a fundamental distinction between two modes of causality. I call these because-of causal mode and so-that causal mode. We can think of these as two ways of explaining an event.

Because-of causal mode example: a man walks into a bank and we ask for an explanation. One explanation tells us about the neurons firing in the motor cortex of the brain that excited a cascade of additional neuron firings, and then muscle flexing. And, of course, there was the mass of the body, the friction of shoes against the sidewalk, the heft and leverage of the doorway, and so on. This mechanical explanation makes the event intelligible; it tells us how the event took place. It took place because of all these enabling factors.

So-that causal mode example: There’s another way of making the event intelligible, and that is to explain the purpose of the man’s actions—he went into the bank so-that he could deposit some money. This is a teleological explanation.

The scientific because of explanation is concerned with immediate past events—facts about what things happened and theories about how they happened. Meanwhile, teleological explanations focus on future outcomes involving values. A teleological explanation tells us that an agent is acting for the sake of bringing about an intended state of affairs—causality guided by purpose. All living systems act with purpose; they seek beneficial outcomes; their behaviors are goal-directed, functional. They are about something.

Here we have two modes of causal explanation—both claiming to render events intelligible, but in different ways. There has been a long tradition of attempts to conciliate these two modes of causality, a tradition that I will now grossly oversimplify. Some people say that the so-that mode of causality is a mere illusion, or at best, a convenient pretense. They believe there is only one kind of causality, and that all genuine explanations can be reduced to the logic of because-of causality.

Others believe that teleological explanations are real, insisting that the universe has some sort of inherent or endowed purpose—it has a point, it is about something, for something. The entire universe behaves in the ways it does so-that an ultimate purpose in creation might be achieved. In one approach because-of causality is ultimately real and so-thatcausality is a fantasy. In the other approach so-that causality is ultimately real and the because-of causality of science is merely an instrument for working out an ultimate cosmic purpose.

The cosmic bus isn’t going anywhere that matters. It has no driver and no destination.

Here’s the big question prompted by our encounter with contemporary science: is the grand epic of cosmic evolution in some way driven or guided so-that some destiny might be achieved, or is the cosmos, despite its awesome splendors, ultimately void of genuine meaning or purpose? As Steven Weinberg famously said, “the more we know about the universe the more it appears to be pointless.” There are difficulties with each of these views. If you claim there is genuine meaning somehow inherent in the cosmos, then you must tell us what it is and why we should accept it. But if the claim is that teleological dynamics are not genuinely real, then you are left with the problem of convincing us that meanings (e.g., values, expectations, the force of will) fail to have genuinely real consequences.

I wish to offer a third option, one that avoids both problems. This view says that all the elements of so-that causality (goal-directed behavior) are genuinely real phenomena, but they are recent and unintended emergents of because-of dynamics.

We might frame this emergence view in terms of two different perspectives on the nature of matter: the grunge theory and the glitz theory of matter. The grunge theory says that matter isn’t much—it’s just some sort of vague or chaotic and uninteresting stuff that becomes interesting only when the laws of nature or the will of God whip it into shape. So the grunge theory appears to assign matter to one domain, while relegating both natural law and divine purpose to another. 

I want to reject the dualism of this view in favor of what I’m calling the glitz theory of matter, which holds that there are no independently real laws of nature. What we have are simply the properties of matter. A law of nature is just something we formulate as we observe regularities in the properties of matter. If we take this view then we can see that matter is not boring grunge, but wonderfully interesting and creative stuff. What makes it interesting: when certain properties of matter interact with other properties of matter, we find increasing probabilities that novel and unanticipated properties of matter will emerge spontaneously.

Here’s a simple illustration: Oxygen and hydrogen atoms have distinctive properties, and when they interact they can produce water molecules, which present new properties not found in either oxygen or hydrogen. And then the interaction of water properties with other properties of matter will increase the probability of even more novel properties. And, as proposed above, the emergence of new properties of matter may result in the formulation of completely new laws of nature. All of this follows the straight-forward logic of because-of causality. As interactions continue the probability of getting large molecules will increase, and when you have interactions between large molecules, then the probability of emergent living systems will increase dramatically. And as living creatures arrive on the scene, so too does the visionary logic of so-that causality. In a fundamental sense, the story of creation is a story about shifting probabilities and how these result in the various entities, events, properties and relations that make up the natural world.

I want to suggest that the goal-directed causal dynamics of teleology amounts to an emergent property of living systems. Before the appearance of living systems causality was limited to because-of dynamics, but with life comes purpose and value. Now agency enters the picture and things begin to matter. Living systems behave in certain ways so-that they will survive and reproduce. Molecules don’t do this. Molecules are created and constrained entirely by the care-less dynamics of because-of causality. But when molecules get really complex and interactive then it becomes more and more probable that they will gang up and behave according to a completely new mode of causality. This does not mean that because-ofcausality becomes overruled or deactivated. It means only that the because-of dynamics have called into play additional sets of anticipatory, goal-directed algorithms. 

A meaningless universe has inadvertently, accidentally and aimlessly created the conditions for meaningfulness.

Purposeful behavior and meaningfulness are real phenomena, not illusory; but they are also recent (~4 billion years ago) and localized (on Earth, at least). This suggests that the cosmos itself is essentially absurd—it has no meaning; it is not guided or coaxed by any agent or purpose. It is not about anything. However, without question, there are pockets of genuine meaning and purpose within the cosmos, as we are here to attest. The cosmic bus isn’t going anywhere that matters. It has no driver and no destination. But there are living beings on the bus, and they hustle here and there with all kinds of determination. My life, your life, all our lives, can be rich and full of meaning without having to claim they have cosmic significance. Life can be worth living even if we are not the point of some cosmic drama. The thing that impresses me most about the cosmic drama is that a meaningless universe has inadvertently, accidentally and aimlessly created the conditions for meaningfulness. This mysterious and wonderfully ironic accident—dare I say, “miracle”?—takes my breath away. 

By “miracle” I do not mean an impossible event occurring at the behest of an all-powerful supernatural agent. I mean only this: any event, the occurrence of which is considered to be so radically improbable as to be virtually impossible. (I am excluding logically impossible events from discussion because they have a probability of zero—even gods cannot square circles). A miracle is an event having a probability value so close to zero that you cannot imagine any conditions under which it might occur. Given these terms, it might be said with good reason that many miracles have occurred in our universe—it’s just that they never occur before their time.

A thought experiment might help to clarify this. Suppose we place ourselves backward in time to some point immediately after the primordial Big Bang, when the universe was nothing but a raging inferno (no quarks, no atoms, just pure radiation) and consider the prospect of a supernova. Nothing that might have been known of the natural world at the time could possibly predict or explain the formation of stars, not to mention their fusion and expulsion of atoms. The very idea of such events would be considered so improbable as to be preposterous, impossible, and contrary to nature.

 Life can be worth living even if we are not the point of some cosmic drama.

Or, let us go back a mere four billion years. Again, at that point we would be completely incredulous if faced with the notion that billions of tiny objects would soon be exploring about on our young planet and behaving in complex patterns that defy all that could possibly be known at the time about the natural order of things. And yet, lo and behold, living beings emerged, not because of some magic wand, and not because of necessity, but rather because a countless series of unpredictable probability-enhancing events brought forth the enabling conditions. 

We have the meaning-bearing lives we do because they were made incrementally less improbable by the epic events of cosmic evolution, whereby matter was distilled out of radiant energy, segregated into galaxies, collapsed into stars, fused into atoms, swirled into planets, spliced into molecules, captured into cells, mutated into species, compromised into ecosystems, provoked into thought, and cajoled into cultures. Surely, there is nothing intellectually shameful about embracing the staggering beauty and the humbling fortuity of these events as … miraculous.
