Life attempts to propagate its genes. Just look at salmon, or bees. Both are willing to die to help the next generation.

Leaving a corpse in a den could kill your offspring via disease. Recognising that survival is no longer viable, and acting to protect them makes complete sense.

Something that might be related is the burst of functionality that mammals seem to get, just before dying. In pack animals, an otherwise crippled animal can get up and leave the den. Biologically, this is to get the dead body away from the den site.

Something similar can happen in humans. A dying patient will suddenly perk up and seem to make a miraculous recovery. Nurses unfortunately know that this is false. The patent will burn out and crash soon after. Patents in this state apparently get a feeling of impending doom. This is likely what drives other mammals from the den/nest site.

What they are seeing might be related to this. The brain gives up on survival, in order to try and not risk the health of family members. Often the damage would be too severe, and so the patient doesn't wake up. They just get a burst of neural activity as priorities suddenly change.

We actually use very little of our muscles full strength. In fact most of thee initial strength gain of weight lifting isn't actually an increase in muscle, but of control. Under enough adrenaline the limiters come off. 5-20x normal is completely possible.

The catch is the damage. Our tendons and supporting muscles are not built for the forces. Dislocations and tendon damage are severe, if full power is used. It also damages the muscle itself. A lot of the overhead is to allow for sustained functioning. Burning it all at once works, but it can't be sustained without destroying the muscles involved.

Basically, the body self protects. When required, emergency power can be unlocked, for a price.

I know they mapped out 2 seasons. Didn't Gaiman have to come up with season 2 to properly wed season 3 to the end of season 1?

I'm definitely looking forward to season 3 either way.

Because it leaves the blind leading the blind, leading to really stupid ideas getting too much traction. Both in being too aggressive, and being too passive. Neither work well.

It also creates a biased pool, which helps fuel the really negative views of women.

It's the same effect as happens in weight loss groups. Those who succeed tend to move on. Those that hang around and gain "authority" tend to have failings.

Don't get me wrong, it's a good thing for the people involved, but bad for those left.

Not got anything to particularly hand. It's mostly offhand articles and pub discussions (drunken freeform thinking is remarkably common and useful in physicists, let alone with undergrads). By its nature, it is into the realm of philosophy, rather than science. It is untestable, since there couldn't be any communication with other bubbles.

As for the time flow, it's fairly arbitrary. We perceive ourselves moving through time via indirect means. Those are potentially an illusion, even in our bubble. The rate of entropy, or the speed of light could be vastly different. That would change the perceived "speed of time" (whatever that means!) compared to some arbitrary communal rest frame.

The big issue is that we don't currently understand our own space-time. Speculating on over variances is very much "how many angels can dance on the head of a pin".

If you want something a little more scientific, cosmic bubble theory is the current version of the theory.

Oh, and the same base assumptions basically preclude FTL. In a relativistic universe, FTL is time travel, with all the resultant problems (tachyonic anti-telephone being just the most obvious)

I've got a lurcher. They have an annoying habit of doing extremely close, high speed flybys. It wouldn't be an issue except he kept messing it up and you'd get a glancing blow from a 30kg+ bullet.

The solution was slightly evil, but effective. We started sticking a foot out in front of him. It took a few tumbles, but he learnt to leave a meter or so of clearance.

Unfortunately, despite 6 years of effort, we have yet to break him of the high speed mud skids (Running towards us, then slamming on the brakes. He then skids to a stop in the mud in front of us, before accelerating away. This tends to spray us with mud).

Proviso, comment is based on old memories.

There was some research done on how women flirt. Women particularly put out IoIs (Indicators of Interest). These include things like hair flick, lip touching etc. When a woman is attracted to a man, the rate of IoIs goes up, sometimes 200-300% baseline.

Unfortunately, the catch is the baseline. Women vary widely on this. Some normally use 2-3/hour, others all the way up to 120/hour. This is where men can often get in trouble. A woman sending them 60/hour might be a 20 flirting outrageously, or a 120 who is actively disinterested. Trying to advance things will get vastly different results with these 2 women.

Because of this, a lot of men get risk adverse. Even if they pick up on the hints, they are not sure if they are reading them right. Conversely, a few men go the other way. These men tend to have a disproportionate, problematic effect on women. This is why most men don't think that sleazy, overly handsey men aren't much of a problem, but women vastly disagree.

Basically, men are stuck in a "damned if they do, damned if they don't" situation. Even worse, the men who figure things out tend to find a good partner and pair up, taking them out of the pool.

To add to the confusion, what women say they want, and what actually works can be quite different. The same applies to men. However, since men are generally expected to make the first move, they tend to screw it up a lot more (and get burnt).

A virtual machine is still an option.

Interestingly it's possible the universe could be older elsewhere. One of the theories regarding the big bang is that space-time underwent a phase change. The higher level phase had sufficiently different physics to let the energy level equalise despite the speed of light limits.

There is no reason the entire thing collapsed back into its current state at once. 1 theory has it happening as energy density dropped below a critical limit. Others have "bubbles" of "normal" space time forming, and expanding through the unshifted medium. There is no reason bubbles couldn't be massively apart, temporally. The catch is, the bubbles will likely never have any communication, rendering the point abstract at best.

There's also no reason the bubbles collapsed the same way. Other bubbles could have a vastly different flow rate of time, or a different number of spacial dimensions.

This is all head-of-a-pin physics however. As it stands, we couldn't detect even a type 3 civilization out near the edge of our observable universe. That is also before light cone issues.

That relies on the "tired light" hypothesis being correct. It solves a number of problems, in a more elegant way. However, it also requires explanations for some new mismatches. E.g. why the cosmic background radiation doesn't seem to have aged the same way.

It's a theory that can't be immediately dismissed, which makes it interesting, but it's far from proven. Scientists can now look for details that would differ between the 2 models, and so help clarify what is happening.

Most will still work without an internet connection, you just lose some of the QoL functionality. I believe some can also work with Home Assistant, for self hosting those functions. Unfortunately they generally require an initial internet connection to set up.

I invested in a self emptying one. It empties the dustbin and automatically cleans the mop. I just have to dump the waste water every week or so, and fill up the clean.

An encryption scheme is only as strong as its weakest link. In academic terms, only the algorithm really matters. In the real world however, implementation is as important.

The human element is an element that has to be considered. Rubber hose cryptanalysis is a tongue and cheek way of acknowledging that. It also matters since some algorithms are better at assisting here. E.g. 1 time key Vs passwords.

The purpose is to access the data. This is a bypass attack, rather than a mathematical one. It helps to remember that encryption is rarely used in the abstract. It is used as part of real world security.

There are actually methods to defend against it. The most effective is a "duress key". This is the key you give up under duress. It will decrypt an alternative version of the file/drive, as well as potentially triggering additional safeguards. The key point is the attacker won't know if they have the real files, and there is nothing of interest, or dummy ones.

Not necessarily. All we know is that everything seemed to come from a single point, on a cosmic scale. However, at that scale, our entire galaxy would be considered a single point.

What we do know is that everything is expanding, and that it was homogeneous by the point that it cooled enough to cease being a plasma (and so opaque to light). It could have been a vast area that suddenly spawned matter/energy, rather than a single point.

6 months later, not a pirate is to be found, dead or alive, and not a single ship taken. Meanwhile, none of the crews will talk about "Trevor". All they are willing to say is that "Trevor is a very very nice man, we were very happy to host him." Always spoken with a monotone 1000 yard stare.

Well, that's no ordinary rabbit! That's the most foul, cruel, and bad-tempered rodent you ever set eyes on!

Interestingly, the turbo button didn't speed up your system. Turning it off deliberately slowed it down.

This was needed since some games etc assumed a fixed clock speed. When the clock ran faster, the game ran too fast. Pressing the turbo button to off was one of the first attempts at an emulation of older systems.

The real European cryptid.
