Seriously though, if one does go vegetarian then it should for some medical or some other sound reason but to become a vegetarian simply because of 'killing animals' imo is not really good enough...we still have to kill plants to eat them. Okay, I know there's a big difference slaughter houses and a threshing machine...I got an idea...don a loin cloth, grab a big club and go and kill our own food ????

With improved technology we are able to detect a reaction to stimuli. But experiments on plants goes back many years. Darwin wrote about it. In earlier times the experiments were mainly on plant movement. For example, it was found that in plant roots certain cells respond to gravitation, cells called statocytes. (one of the reasons plants were taken aboard the space station). Botanist have also described that trees communicate with one another via both air and roots. A 2018 Smithsonian article also included '...University of Western Australia has gathered evidence that some plants may also emit and detect sounds, and in particular, a crackling noise in the roots at a frequency of 220 hertz, inaudible to humans.' Well, plants are alive aren't they so why not have a response mechanism too.

Unless AI does it first ????

A) Agreed. I was thinking about the very early ideas on what might be (eg. Oppenheimer 1939, collapse would result in in gravitational tidal forces so great as to produce a point of infinite curvature and density. Oppenheimer didn't continue researching this because of the atomic bomb projects.). However, R. Penrose used an hypothesis of cosmic censorship which would deny such 'naked singularities'. . At r = 0 several hypotheses have been suggested which depend on the parameters of a BH and what coordinate system is used. Another consideration is that of QM where it is suggested that violent QM processes control the outcome. I think it was Wheeler in the early 1960's who stated because of such extreme conditions inside the EH that our (then) known physics and math break down and perhaps the answer would be in terms of quantized gravity. As you probably know today several QG hypotheses are being research but unfortunately the 'graviton' particle has yet to be identified. B) Geometricdynamics does suggest that 'locally' near a BH space-time is stretched but outside of this 'local' region the effect falls off quickly. The BH being presently discussed (as I mentioned) has a EH that is so large that the gravitational (force) at the limit is much less than of Earth (using the common Newtonian equation without GR correction). This probably contributes as to.why it is not very 'active'. Another point might be, emphasis on 'might', that any DM outside the 'local' limit might have an influence on any 'stretching'. Nevertheless, I don't see why any ideas should 'thrown out' because NH are mysterious objects...????

4/4 ✔️????

What is wrong with this guy! I bet he thought Ukraine would tumble in a day or two...well he got that very wrong so what does he think he is going to do with the Nordic countries. I can't understand why his chief military personnel go along with him. Is he hoping that the Chinese will join him in a real fight with the west? Well they might do but only for their own means, I'm guessing, for when Russia is exhausted perhaps it might suddenly become a Chinese annex.

This massive BH is in the galaxy cluster Abell 1201 and estimated to be about 2.7 billion light years away in the Constellation of Leo. Most of the large BH's are quite active emitting considerable amount of X-rays but this latest find is considered to be not very active. It was found by model simulation of images of the foreground gravitational lensing. For this BH my rough calculation would give a Schwarzschild radius of about 9.7×1013 km...that's big. There are a lot of hypotheses about what is inside a BH, one of the most recent being about DE. ('if nothing can escape from a BH from inside the EH then how can DE from a BH affect the rest of the universe?' is one of the objections to this idea.) The point is we just don't know. If we try to figure it out using some basic arithmetic then the idea of a singularity of infinite density would mean that sound in that infinite density would travel faster that light. Well, we can't have that, can we! Magnetars are just about as close as a star can get without becoming a BH (a mass of about 1.5 of our Sun but only 20 km in diameter) and are the strongest magnets in the universe so some scientist think that magnetohydro dynamics plays a part inside a BH (along with QM).

Not really a new idea, has it's been around for decades now. Like all technology, it has a plus and minus side. In the future Robots could be sent to other planets where they could be made to determine what was required for a human visit. Make no mistake, mining on the Moon, Mars etc. will come at some point so what better use for a Robot. I think what most people are concerned about is just how far scientist want/will go on AI's ability.

Yes have seen the videos a while back. But lots of problems remain. Did you notice the granular nature of the impacted asteroid? With a suitable explosive this one might disintegrate into its 'granules' which probably wouldn't present a problem. But asteroids vary in composition and makeup so a deflection would need the right type of explosive. Would we have enough time for a minor impact to relay the necessary data? A complete deflection would also be required for imagine an 'incoming' bound for, say, some western region but only partial deflection was effected...and there was an impact in an eastern region. Perhaps in the future there will S.S. 'Outposts' which could deflect at a much earlier stage.

It isn't a question of 'if' one sizeable rock will hit Earth, it is 'when'. In the near future we may be able to defend against something of, say two to three meters but something of kilometre size...

In fact, it is your incorrect terminology that was the problem. An orbit describes a 2 D plane, not a 3 D volume and your area of π⨯2d still does not equal 3⨯108 km2.. π⨯2d = π⨯2(2r) π⨯2⨯(2⨯149⨯106) =1.87⨯109. Your pixd2 is incorrect notation because 'd' denotes diameter, not radius.. And why did you not use x2 given in the ribbon at the top of the comment window, instead of 'squared?. π⨯2r= π⨯2⨯149⨯106=9.36⨯108 which is the circumference of an assumed circular orbit, not an area. The surface area of a sphere whose radius is 149⨯106 is 4πr2=4π(149⨯106)2 = 2.83⨯1017 km2. However, in reality this is also incorrect because the solar system isn't static and is moving through the galaxy at about 7⨯105 km/h. Going through space-time this might describe a cylindrical motion(in very rough terms) whose volume would be πr2h and surface area of 2πrh, 'h' would be the amount of time to be considered (I think Omuamua had a velocity of around 95,000 km/h)

Hmm, the average Earth/Sun distance is 149⨯106 km = radius, area = πr2 = 6.975⨯1016 km2

Very well then, please give an example of a person in that condition would proceed...assuming the Doctor is under a Hippocratic oath?

The only way out of this is to create different categories. Sponsors? Well I would have thought there will be enough support for the 'trans' group who will be willing to to pay.

and with such news items as; Pentagon officials speculate alien mothership could send mini probes to Earth. Well, I suppose frozen Hydrogen could be a possibility (freezes at about 14o K above Abs. 0 but it does rather depend of how much there was. If there was just a small amount then surely that would have 'boiled' away on its approach to the Sun with none left for the outward journey. Another point is that wouldn't Hydrogen be present over all its surface and both 'ends' boost might cancel rather than boost it in one direction?

If you mean 'vegetable' in that you are brain dead and a machine is performing functions then as always, I would have thought doctors would consult the family and it would be their decision. I don't think that comes under 'assisted'.

Not sure if that's the problem though. Yes, I agree with your statement but is it right/ethical etc. for you to expect someone else to assist you? Just as you have the right so does someone else in refusal to assist...which possibly could include, by extension, the law makers/physicians (oath and all that).

The Guardian; I shuddered a bit when I read '...imposing death penalty...'

Much of the Cobalt comes from the Congo (unlike Lithium) and if the news outlets and videos are anything to go by, it isn't a pretty sight, Child and cheap labour etc. Now before I get criticised and labelled as being against 'renewable' (non-fossil fuel) energy, I am most definitely not against this progress. But the chemicals that we use to research & advance don't offer themselves up without difficulty and much effort is expended to do so. It can't be very satisfying to know that the product you sell is made possible by people working under such difficult conditions and who will probably never be able to buy your product. So I think there is move to try and distance a company from possible Child and cheap labour criticism. I hope one day we can get over these ironies and obstacles.

Yes, I know and that's is implied in my comment (I mentioned Russia before Putin). But also implied is that as Leader he could take the chair.

Anyone here, or abroad, that is going to volunteer to 'cuff' Putin? Isn't he due to take Russia's turn as Pres. of the UN Security Council? Maybe he'll suggest making the Solntsevskaya Bratva a legal institution and hire them as his bodyguards, ha!

Yes, but then he knew what he wanted the stuff for. I doubt that's the case here.

Don't recall seeing chandeliers in police stations or immigration...perhaps they use a ceiling fan? Difficult to swing on a a.c. unit

Yes, and Ballet was her true vocation and entered the Royal Academy in the UK. While she had no 'formal' training in the martial arts she trained alongside others in gyms when her movie career started. But Ballet dancers have all the flexibility in their limbs necessary for martial arts.

Although I understand your point of view, indeed, I contend this war should end. However, none of the alternatives seem acceptable or wanted; if the 'allies' of Ukraine help with a deciding blow towards Russia then probably Putin would have no alternative but to use a nuclear strike and WWIII will start. If Russia is allowed to apply the winning blow then we don't know this would affect Putin's 'boldness' for further invasions in the future.
