We do, light travels 1 lightsecond per second.
Oh, and 1 lightpicosecond is around 2.998mm.
100 lightpicoseconds is also very close to 1’.
- Comment on How would you quickly describe Lemmy to a non-fediverse person? 1 week ago:
I’ve found comparing it to email works well. It’s about the only (mostly) decentralised service that most people have used.
“It’s like Reddit, but is decentralised, like email is.”, “This makes it far harder to manipulate to hide information.”

The momentum matters when you hit something. A large truck has a lot more momentum than a small car. If it hits something it needs proportionally more force to stop it. Since forces are equal and opposite, that means the hit object has to absorb more force. Basically thing of the difference between someone dropping a marble on your head from a balcony to doing the same with a bowling ball. It’s the same with a child hit by a vehicle.
For passengers, only their mass matters. Whether you’re in a car, a truck, a train or an ocean liner, all that matters is the person’s mass and the rate of change.

Making a lot of us angry. Unfortunately we are not as good as the french at complaining about it.
We also have the issue of this party being the better of the 2 viable options.
There’s talk of a new party forming, to the left of modern labour. Unfortunately, in a FPTP system, that can split the vote and make things worse, if done poorly.
- Comment on Woof is dog for "You may test that assumption at your convenience" 4 weeks ago:
It’s often one way or the other. “Get away from me!”, or “more babies!” Pregnancy hormones do a complete number on the mother. That’s before having a parasite attached to you near 24/7, demanding your attention, day or night!
Interestingly, her pheromones can do a similar job on any males around her (both human and dog). That was an interesting surprise.
- Comment on Woof is dog for "You may test that assumption at your convenience" 4 weeks ago:
That’s a trick many/most breeds of dog can pull off. It’s amazing how well a wet nose, and a slobbery smile shoved in your face can break a bad cycle.
There’s a reason they are used as emotional support animals so often. They can guard us from ourselves almost as well as this dog did the sheep from coyotes.

Given what it does, it eating you might be considered more humane! But no, is the fuck you, I just want to cause pain tree.
- Comment on Why don't they have simpler names for brain disorders, where perhaps even the person suffering the disorder might be able to remember the term themself? 2 months ago:
Latin is used BECAUSE it is dead. It means the terms don’t drift. It also lets the names/terms be a descriptive as necessary.
Asking a doctor to memorise some Latin words is a lot easier and less error prone than a sea of acronyms.

Fully agree with that. Tesla got thoroughly screwed over.

He could give lectures, but the computer massively slowed conversations. He also apparently had a bit of a temper. Some of his colleagues took to wearing steel toe cap shoes because of him (electric wheelchairs are heavy).
- Comment on Let's hear it, little lemmings. 2 months ago:
Apparently he didn’t trust patents etc. He would come up with fanciful ideas, that sounded vaguely plausible, as cover for what he was actually working on.
At this point picking apart the Good, the bad and the cover is an …interesting exercise.
- Comment on [deleted] 2 months ago:
It can, actually be done. It’s just inefficient and requires too much trust.
You either do a general broadcast of power. This is incredibly inefficient, at any real range. To get power to the edges, the power near the transmitter will likely be enough to cook your cat.
The other method is directed. You basically put out a power beam that improves efficiency. Unfortunately, you also now have a directable energy weapon in your living room. I wouldn’t trust something capable of cooking my brain, while I’m sat on the sofa, if it gets hacked.
Neither are likely viable for general use, though both could be useful under certain conditions.

My brother laser fits into the same basic role. I paid extra for the colour version however. The key is that laser toner never goes bad, unlike inkjets.
- Comment on Emma Watson banned from driving for speeding 3 months ago:
It’s actually not law, just custom. Most/all speedometers over estimate for this reason.
The motorway cameras, near Birmingham have been known to issue tickets for doing 71mph.
- Comment on Emma Watson banned from driving for speeding 3 months ago:
I would be wary of those roads. I’ve ran across several that seem like national, or 50 roads, yet limited a lot lower. Generally, there is a hidden danger on that stretch. The classic being a blind junction joining, or a school kicking out nearby. It won’t be obvious, unless you are familiar with the area.
At the same time, i also know of a 30 limit on an otherwise national road. It’s along the stretch in front of a previous Mayer’s house.
- Comment on Belkin is ending support for nearly all its Wemo smart home devices 3 months ago:
It’s our normal language for referencing each other. “The wife”, “the husband”. I’m sorry if it offended you.
As for the WAF comment, it doesn’t mean she can’t fix it, just that she has no interest in the nitty gritty of how it works. This seems to be a common occurrence with smart homes. It’s FAR more likely the male partner is interested in building it. The female partner tends to only care that it works. (And that their partner is enjoying themselves).
So far this gender stereotype holds up strongly (90%+)
- Comment on Belkin is ending support for nearly all its Wemo smart home devices 3 months ago:
There’s an open source movement basically solving this sort of problem. I’ve had various smart home things working flawlessly for a decade or more.
The key is twofold. To make sure that support won’t be dropped. Offline functionality is a key indicator of this. Open source firmware is even better.
The 2nd is WAF. Wife acceptance factor. How transparent is it for normal functioning, and does it fail gracefully. E.g. my light switches all work normally. If the network goes down, they fall back to dumb switches. The wife never has to deal with “the lights are broken” while I’m away with work.

I’ll check it out, next time I get a chance to fire it up. Unfortunately, I hate the teleport mechanism of vr games. I love hurtling through the water. Unfortunately, that also makes me motion sickness. I’m slowly training myself out of it, but it takes time.
- Comment on Baby dies after California mom leaves him in car to get lip filler on 101-degree day, police say 3 months ago:
It depends how often you drive without the kids.
If you don’t always drop the kids off yourself, it’s easy to get half way to work on autopilot before realising you meant to drop them off.
Sleep deprivation is a weird thing.
- Comment on Baby dies after California mom leaves him in car to get lip filler on 101-degree day, police say 3 months ago:
As a parent myself, I’m now doubly amazed at how few cases of forgetting happen. It’s so easy to do, and your brain is reduced to blomonge by sleep deprivation.
FYI, the “baby on board” signs aren’t generally meant as “don’t crash into me” signs, but “assume the driver is drunk and distracted” signs. Having been there, I try and give them plenty of space!
- Comment on Pop it in your calendars 3 months ago:
It was even worse than that.
They were basically given the KSP1 codebase and told to rewrite it to be better. However, KSP1 was still being developed, and they didn’t want to demotivate the KSP1 team. Therefore they were banned from even telling them it existed, let alone ask for help or advice with the existing codebase.

I want to love it in VR. It’s taking me a long time to train my stomach to accept it however. It gives me SERIOUS motion sickness in VR.
- Comment on Pop it in your calendars 3 months ago:
That phase does end. The various vehicles allowed for exploration without returning to the surface, as do deep sea bases.
At the same time, I fully understand why you feel that way. The crunch is required for the fear to be meaningful, it’s not everybody’s cup of tea.
- Comment on Gravity 3 months ago:
Quantum mechanical particles are very different things to classical ones.
A slightly better way of thinking about them is quantised fields. Particles and waves are simplifications of the underlying effect. There is no classical equivalent to work with to this, so we try and understand it as particle-wave duality etc.
In this case, a carrier particle is a (quantised) disturbance in the underlying field. If it has enough energy, it manifests as a physical particle. The higgs boson is an example of this. Below the required energy, you get virtual particles. These “borrow” energy, and so can never be seen directly, only inferred.
By example. Photons are the carrier particle of electromagnetism. Give the field energy and you get photons (light). Without that energy, the photons are virtual. Existing only between the 2 acting entities.
Different fields have different carrier particles. The photon is quite simple. It’s effectiveness decays as 1/r^2 . The strong force carriers are more complex. They can emit more carrier particles, allowing the field to grow with distance rather than decay.
To add more complexity. The various fields look to be aspects of the same field. At sufficient energies, they behave identically. We have figured out how to combine the electric, magnetic and weak fields. We have a handle on the strong field. The higgs field seems to also match into this. Gravity is a pain to study. We assume it should match in, but haven’t managed to work out how yet.
As for why the underlying field exists and follows the rules it does? We have no clue right now. The ‘why’ tends to follow the ‘what’, and we have yet to get a good handle on the ‘what’.

I’ve been playing 5D Chess with Multiverse Time Travel it’s remarkably easy to understand, all considered. It’s only partially mind bending.

As an aspie, we still flirt. We just (sometimes) flirt differently.
- Comment on How good are amphetamines for brain fog? 4 months ago:
It likely won’t help, though it depends on the source of the brain fog. ADHD drugs are aimed particularly at the areas of the brain associated with executive functioning. Under stimulation here can cause brain fog, among other symptoms. Critically, the body’s homeostasis system wants to boost things, but can’t. It doesn’t fight the boost from the drugs, at least in the under stimulated areas.
If the brain fog is sourced elsewhere in the brain then the amphetamines won’t help much. Even worse, a normal Brian will adapt to counter the drugs effect, causing physical addiction. You would need to constantly increase the dose to gain the same effect. That’s the reason ADHD drugs are controlled substances in most countries. People chase the dragon, and end up nuking their brain with too high a dose.
Basically, don’t do it without medical oversight.
- Comment on I'll just take the bus 4 months ago:
Automatics had a bit of a bad reputation, for quite a while. They don’t/didn’t play well with our road layouts. E.g. they could be slow to downshift when climbing a hill, and kick when they did decide to play along. I believe they have improved a lot, but most people are used to manuals, and so more manuals are sold. This makes automatics more expensive and rarer.
- Comment on Talented child artist 4 months ago:
I think it’s a bit of a generational thing. The internet has given us access to a lot more reliable information. Far more parents have learnt the difference between what’s effective and what feels good. Yelling feels good, it doesn’t actually work very well. Rolling with it, followed by a calm discussion gets far better results. Achieving this mentality is another matter, but using it as a goal helps moderate your reaction.
- Comment on Talented child artist 4 months ago:
You can spot the parents here.
They are expressing themselves, having fun, and off the iPad. They even put it where I don’t have to see it too often. I’ll call it a win.
