It’s worth noting that combining the relativistic correction factor into mass is actually quite problematic. It’s a vector (directional), while mass is scalar(directionless). You suddenly need to ask what direction your mass is. Furthermore, a hypothetical person on the ship will still measure their inertial mass as normal.

As it stands, it would take an infinite amount of energy to reach the speed to light, but you can get arbitrarily close to it, with a finite amount (huge, but finite).

They also happen to be a (retired) nurse themselves. It’s uncommon, but not that uncommon. Most nurses would have seen it before. Its only for 5-10 seconds after waking up. Coming from a relatively skinny woman is quite a bit more unexpected. She also has unusually good aim.

I know someone who has had quite a few general anesthetics. They’ve taken to warning the nurses involved that they are a puncher. Several have not taken it seriously and ended up with some impressive bruises (including black eyes).

I saw a talk from someone working in the field a few years back. The “fusion is only 10 years away” had a small proviso “if fully funded”. The actual funding was barely enough to keep the lights on.

That has now changed. It’s gotten close enough that private investment has decided it’s worth investing in. I believe the only really big problem left is the wall material. The neutron flux transmutes the elements making it up. This makes it difficult to maintain a hard vacuum, since the wall can start leaking and/or outgassing, forcing a shutdown to replace them. On a minor plus side, if you dope the walls with mercury, it transmutes to gold, in commercially viable amounts!

Fusion has several advantages over fission. The biggest is the impossibility of a meltdown. The very difficulty in balancing the reactor means that it shuts down fast and mostly clean. This would let them be placed far closer to population centers. They could provide a base load supply, in the way nuclear could/should have.

The bacteria don’t need to be identical.

Think of it like rolling a dice. Any given roll can only have a single number. However patterns can be detected by combining multiple rolls. E.g. a biased dice.

As for larger things. It’s possible, but the speed required goes up with mass, and not linearly. In theory a person could go through. They would be moving a significant fraction of the speed of light however. Catching them alive on the other side would be… difficult.

Only 1 bacteria ever arrives. It’s the probability wave that interferes with itself.

With the Young’s double slit experiment, if you fire a single photon, you get a single photon arriving. It looks just like how a cannon ball flies. It’s only when you let hundreds go (either collectively or individually) that the interference pattern appears.

The end pattern is the probability that the photon (or bacteria) arrives at any given point on the receiver screen.

Anything moving has an associated wavelength. If that wavelength is long enough, you can do the young’s double slip experiment on it.

It was a few years ago, so the details are hazy. A scientific team accelerated a particularly small and sturdy bacteria fast enough that their speed produced a viable wavelength. They then sent the stream through 2 slits. They then captured the bacteria in aerogel (I think) to slow them back down.

Most didn’t survive, but some both survived, and ended up somewhere they couldn’t without interfering with themselves. They successfully reproduced afterwards. The debris also followed the classic ripple pattern of the experiment.

Basically, there is nothing special about “life” when it comes to quantum mechanical effects, other than it’s on the big side.

They have also experimentally tested an equivalent experiment with bacteria. They survived a trip through the double slit experiment.

There doesn’t seem to be an issue with it, other than it’s difficult and impractical.

There are 2 parts at work. The focus reflex and the blink reflex. The window between them is the dangerous part. If the pulse is fast enough ( a few ms) then the eye can’t focus, and it’s fairly safe (unless you were already focused on the emitter). If the pulse is low enough power then the blink reflex kicks in and protects your eye.

Hitting a mosquito is a hard task, tracking one is even harder. It’s better to use an ultra short pulse, with a bit more power. You can also shift the frequency. If it’s an infrared laser then the eye won’t lock onto it, and will struggle to focus it dangerously.

This idea was tried previously. If done right, it doesn’t take much energy to damage a mosquito’s wings.

Secondly, a laser is only a real issue for vision if the eye focuses on it. With a continuous beam, it would be instinctive, making it dangerous. If the pulse is short enough however, the eye won’t have time to focus and so the power will be safely spread out, even inside the eyeball.

Basically, an “instant” communication device can create paradoxes.

E.g.

Earth sends mars a instant message. Mars the relay’s it via normal radio to a passing ship/probe moving at 0.99C. That probe then sends an “Instant” message to Earth.

The final message will (depending on alignments etc) arrive before the original was sent. If the message the voids the reason for the original message to be sent then a paradox happens.

You can make similar things happen with any form of FTL communication. C isn’t technically the speed of light, it is the speed of information. It just happens that light has no other speed limiting, and so moves at maximum speed.

I thought it was mostly a jamming type effect. The memories are often still here, but become progressively less accessible. They then degrade from lack of use.

It might well be that a lot of memories still exist for longer than it seems. Even if not, stopping the degradation, and allowing new memories to form would allow people to remain cognitive and functional for a LOT longer.

A lot of the big building companies, in Europe, treat solar panels as a premium option and so charge a larger profit margin on them. Installing solar, while constructing the house is a LOT cheaper and easier than retrofitting them later.

The panels have gotten cheap enough that it’s no longer a real cost burden, Vs the cost of the house.

I’ve also got a steam deck. Unfortunately it just doesn’t cut it for games like satisfactory or factorio.

Luggables are quite common for gamers who travel a lot. I can’t take a tower into hotels easily, but most of my free gaming time is on the road. I know quite a few people with portable gaming systems.

My current laptop is rocking a 4080, with a water cooling loop. It has to fall back to internal graphics when on battery. The batteries just can’t provide the current required.

I’ve played with some qidi printers. I’ve found they are not the most reliable printers around.

It was a older machine however, so it might have been a unit issue, rather than a company one.

Octoprint is amazing. I’ve used it for years with my old ender 3.

Unfortunately £1678 (Core 1 + indx) is well outside my max budget for a hobby machine.

That was definitely a nail in the coffin, as far as I am concerned. They’ve not passed my ‘sniff test’ since the start. The legal threats just show that they are doubling down, rather than backtracking.

Prusa has at least built up some credit with the community. Bambu came in planning on locking people in.
