Does that mean you understood everything I wrote/said?

Absolutely not, but I don't think that's the fault of print. Do you think it would have been clearer to me if you'd spoken the same words to me? I think I'd have been equally baffled.

Is it really that obvious? 

What exactly did you say 10 years ago to your friend about that politician? I never heard it so I can't remember, but I'm sure you both remember exactly.

OTOH, I have access to many things you wrote 10 years ago. So yeah, really obvious.

For instance, Socrates wasn't a fan.

I think he assumed writing his ideas down fixed them that way permanently, so he couldn't change his mind once he'd written it. Of course we now know, through scientific methodology, that it's possible to write down our best current explanations without cementing them in place. So perhaps Socrates was wrong about this. I assume you're grateful his students weren't so stupid.

Really, doesn't that dismiss causality, in a fundamental way?

Or rather it acknowledges that I probably won't ever talk to you face-to-face, again for obvious reasons.

We're very clever apes with a penchant for breaking boundaries and the written word has no more value than the spoken word, in advancing our understanding of the available knowledge.

Not clever enough to see the obvious value of preserving the actual words someone once spoke, apparently. Nor clever enough to see that the written word can be dispersed much more readily than passing them down orally, apparently.

I think the written word is MUCH more valuable than the spoken word in many aspects. I can practically guarantee it will be the only way you and I communicate, whether that advances our understanding of our available knowledge or not.

While the written word didn't stop anyone from lying, it did make the lies easier to spot. The spoken word allows one to use all kinds of misdirection, as we see throughout history and especially with modern video. The written word allowed us to trust each other better.

You don't have the ability to imagine? What if I said visualize? Can you do that?

Well, the first thing you ask us to imagine is a massive object moving at the speed of light, which is non-physical. Then you talk about velocity as if it weren't a property, but rather a substance. It's easier to imagine things that are possible and physical. 

Anyway, you get 5 posts on your first day as part of our anti-spam measures, so you won't be able to reply until tomorrow.

I am amongst the more pessimistic commenters when it comes to space but the resources in asteroids are real - notably Platinum Group Metals mixed in nickel-iron at 10's of parts per million (going by meteorite samples). Even the nickel-iron, raw and unrefined would be considered valuable here on Earth, just for the nickel content. Most things in space have no potential to make money but asteroid minerals are a real "prize" of enormous potential monetary value, so I think the interest will always be there.

Am I missing something? Why would you bring it back here, where it would be really, really expensive nickel-iron, or really, really expensive platinum? I don't have numbers, but terrestrial mining has to be a lot cheaper in almost every aspect. Does not having to pay for mineral rights offset asteroid mining's inherent challenges and their costs, which include identifying and safely bringing the metals back to Earth?

We can keep the metal out in space to build HE3 gathering facilities, something we'll need more of for quantum computing and medical imaging. Not sure how I feel about mining the moon for it, but we don't need much to make a big difference and it's in limited quantities on Earth. It makes more sense to bring this back.

Anything we don't have to send offworld is a resource we get to keep, so I think it makes sense to use what we find out there out THERE as much as possible. At some point, we'll need the metals from asteroids for more projects out there.

The really intriguing question is however, what prompted this line of research ? Did someone accidentally drop an extra strong cup of コーヒー  or kawa in the electrolyte one morning ?

This had to be it. "I didn't spill coffee on the electrode, I applied a caffeine/sugar solution in the hopes of increasing fuel cell efficiency!"

Is there an analogy that can help explain what took place?

Analogy doesn't help much with this. It confuses things further.

Very simply, so simply that it can't possibly be held to any degree of accuracy: the universe was extremely small, the matter in it was extremely dense and therefore extremely hot, and then the universe (which is everything there is) expanded rapidly (and the last point, working backwards, at which we can accurately measure it is what we call The Big Bang). At some point, the density of matter decreased enough to allow space between it to form, and the temperatures continued to fall.

It could be that all that matter squeezed so small is similar to what happens in a black hole, but black holes happen inside the universe, and particles that fall inside are measured relative to the black hole, and no velocity can change that. When the whole universe is inflating itself so rapidly though, everything is different because everything is moving and expanding, everything in the universe is participating in the event. 

And I've probably made it worse. 

Mining asteroids makes economic sense only if you leave the metals out there, for use in outer space endeavors. Imagine having tons of metal to work with that you didn't have to bring up from Earth's surface a few kilos at a time at hideous cost.

I will research your suggestions and edit the video.

We're a science DISCUSSION forum. We talk about science topics. Videos are difficult to discuss, and take a fixed amount of time to view. We prefer the written word, where we can assess a post very quickly for veracity and accuracy. We can talk about subjects for your channel, but we have no interest in helping you promote your channel, which is usually what people want when posting their own videos here. 

We would love to talk about Earth Science with you. Watching you talk about Earth Science? Not so much.

So it's similar to a pottery wheel with a manual foot pedal, except it's function is just to rinse the mop?

You mean numerology. It's not math.

ok from my understanding, it is the belief that everything is made of vibrating energy including thoughts and people and like energy attracts like energy so positive thoughts attract positive experiences and negative thoughts attract negative experiences.

and my belief is that the aliens abductions and ufo activities are fallen angels and not extraterrestrials like the media claims. 

This seems unproductive as a form of belief, discarding one extraordinary explanation for another. Neither angels nor extraterrestrials have as much supportive evidence as virtually ANY other explanation. Weather balloons are more likely than Michael or Martians.

Are you sure you want to use a platform that forces users to look for help outside the platform's own website? If I'd paid for this, I'd be really mad if they couldn't help me.

Hi Naitche,

I sometimes have such kind of problems too. For me a reload of the web page helps. Maybe you too?

Cheers,

Eise

This happens to me sporadically. Clears right up if you reload the page. I suspect it's a browser issue, but perhaps we should mention it to the Admins to see if it's an Invision bug.

I would imagine there's a point where the stability of having so many legs is overshadowed by the inefficiency of having to move them all, especially on a bigger world with more influence from gravity.

Currently next in line are the two seated behind Biden in last night's State of the Union Address. Kamala Harris and the kid that was making faces to her left.

Not to imply that, if Biden died, Harris would have to use the petulant kid as VP. She would get to pick her own.

Yes, the change of doors, from open to close, can stop/block me from moving through space, 

That's not what my example is showing. The doors closing faster than you can walk is what blocks you, not the doors themselves (you can stop the doors from closing if you get there in time).

but there is no real temporal obstacle, I cannot stop/block your advance in time using objects (or any thing that I can imagine).

But there IS a temporal obstacle, the fact that the doors will close before you can WALK to them. Why do you need objects? The advance of time keeps you off the elevator unless you speed up your pace. Nothing spatial changes, but if you want to get on that elevator, the obstacle is time, and you're capable of using it to get on the elevator.

This is the future if the orange one with the luxurious bouffant wins.

He promises to shift major resources over to immigration control, including the largest domestic deportation in history. 

He promises to close the Dept of Education and give control over to individual states re teaching children. This will include putting prayer back into the classrooms.

He promises to remove the Affordable Care Act, and replace it with a much better plan which he's never revealed before. 

He promises to cut all spending on gender affirming care, calling it "child mutilation". He also wants provisions to prosecute doctors who have EVER been involved in gender affirming care.

He also promises to kill all efforts at producing electric cars, replacing the technology with flying cars that feature vertical takeoff.

And he promises to put a 60% tariff on goods from China, because apparently everyone has forgotten the damaging costs of his last tariffs. 

And he wants every American to carry a concealed weapon, probably because we'll need more slave prison workers if we're going to deport all the immigrants. Best way to fill the jails is to increase the number of guns on the street.
