Really ? So YOUR proof is to actually multiply it out for each number from 3 to infinity ? Indulge us, then. Show the proof that it doesn't work for n=99999999999999999999. We'll wait several months. Then you can start on n+1 !

Can anti-matter travel faster than light speed?
MigL replied to NoahIsTheRealDeal's topic in Physics
That's correct Mordred. In the equation E=gamma[mc^2] where gamma is the Lorentz factor, when v>c, the Lorentz factor is the root of a negative number. For the energy to be a real, positive value, then, m has to also be imaginary. Alternatively, if m is real and positive, then the energy has to be imaginary. -
Can anti-matter travel faster than light speed?
MigL replied to NoahIsTheRealDeal's topic in Physics
IIRC, tachyons arise because in SR, when v>c, the root is imaginary; the mass must, then, also be imaginary, because energy needs to be real. Yet your link states that recent treatments use a real mass. I find it hard to reconcile the two. Guess I'll need to do some reading -
May I suggest that the only thing that was shifted was several pints ( or more ).

Silvestru is not advocating spending less money for services. He is suggesting it be spent more wisely and transparently. And, to be honest, he has a point, but whether his system of payments to service providers would work as he expects is doubtful. There are plenty of cases of Governments bringing in a new tax for some specific purpose, which then gets dumped into a 'slush fund', and re-purposed for some partisan pet project. In my home town of St. Catharines a sewer surcharge was added to the water bill, essentially doubling it since you pay for water coming into the house as well as going out, because our municipal government said the sewer system was in disrepair and hadn't been worked on since the 50s. Well, other than general repairs for immediate problems, no work has been done to improve/expand the sewer system in the 30 yrs since the 'tax' was introduced. All money collected went into general revenue and was used for other things. Not very transparent is it ? There are gas taxes specifically to improve roads and mass transit. There are tire taxes to dispose of old tires. There are vehicle emission tests, which don't check emissions anymore. Etc.,etc. All these moneys are repurposed as the government deems appropriate. Yet no one gets to vote on these decisions. Like I said, not a good system. But not sure any of the alternatives would be any better, and may be much worse.

I suggest looking up the meaning of treason, H Andy, none of the scenarios you suggested amount to treason, which is possibly why the charges won't stick to T Blair. Most European countries ( and Canada ) belong to a mutual protection treaty called NATO. That means an attack on any one country is an attack on all of them. I would assume that makes Poles, Estonians, Latvians, Hungarians, Romanians and Slovakians sleep better at night; And would have helped keep Ukraine whole. I would gladly pay more taxes for my armed forces to keep V Putin out of Eastern Europe, Sensei. Haven't you noticed that Komrade Vladimir likes wearing his Bear suit lately ? And finally to the OP... Taxes are like government and democracy. Not a good system by any means, but much better than the alternatives.

I have mixed feelings about this... Don't know whether to laugh at you or feel sorry for you. You obviously use a computer, which puts a lot of information at your fingertips, yet you don't inform yourself of the simplest scientific facts ?

All lifting ( unless using some kind of propulsion system ) involves a levering action. What would you stand on to lift a tectonic plate ?

I might add that I live 12 minutes away from the American border, and have never feared Americans, even now. Ask the Ukrainians how they feel about the Russians. Or the Tibetans and Taiwanese about the Chinese. Or should I go back through history and name all the forgotten small countries that lived beside a 'superpower'. Edited ( because people at my work are jokers, and add comments when I leave for an emergency )
-
Wow ! Koti gets dumped on for making a joke. ( which I got, and found humorous, by the way )\ While sensei is totally off topic and everyone falls all over themselves to agree with him. Tell me what other superpower during the last 2000 yrs has been as benevolent as the US during the last century ? Assyrians, Phoenicians, Romans, Germanic empires, Napoleonic empires, Hapsburg or USSR ? Or even the British ? No other has helped the rest of the world as much as the US, although at times they have slipped up. ( like when they voted in D Trump )

What are they after ? Reproduction of their species, i.e. survival.

I didn't get the memo... Today must be rant day.

The problem is NOT that you ask dumb questions, as there is no such thing as a dumb question ( although they may be ill posed ). The problem is the wild-ass assertions you make subsequently, that have no basis in Physics.

Bullet fired from a gun and a bullet dropped descend simultaneously
MigL replied to StringJunky's topic in Relativity
That being said, about a month or two ago, someone posted about the longest sniper shot on record, at over two miles, where curvature of the Earth had to be accounted for. Which means there was non-negligible drop off of the Earth's surface, in which case, a longer drop, and therefore, longer time to hit the ground. Incidentally, three of the five longest recorded sniper kills on record, are by Canadians. ( don't mess with us ) -
A graviton will interact with other gravitons, unlike other bosons. Can it gain/lose energy in that way ? ( It interacts with its own virtual particles: that interaction gives rise to the non-renormalizable infinities that don't allow for quantization )
-
Maybe you should have read Wikipedia before you started preaching all your wrong assertions about virtual particles and fields.
-
You just said that light, crossing a void that has expanded, is red-shifted. Then you accuse me of being wrong, and say that light which was emitted at a temperature of several thousand degrees ( which does not allow protons to combine with electrons ), is NOT red-shifted down to an equivalent temperature of 2.7 degrees by an expansion of over three orders of magnitude. I think you're a little confused.
-
I'm just making the point that voters should inform themselves of a party's platform and not simply vote 'as they always have'. But since you're so eager to find blame, instead of solutions... Are you saying neither side should be 'better' and move on for the betterment of the country ? That because one side does it so often, its justified when the other does it less frequently. An 'eye for an eye' as it were ? I think Israel and her Palestinean/Middle East neighbours have been trying that approach for the last 70 yrs. How's that working out ?
-
And how about the ( alleged ) woman-hitting, drunkard J Depp asking if another actor should go J W Booth and kill the President ? Maybe I'm reading too much into the actions and words of these idiotic, attention seekers ( no publicity is bad publicity ) from Hollywood. Yet they have a disproportionally large amount of credibility with tabloid readers, young people, and anyone whose mind is easily influenced. And then people get shot ! ( oh wait, that already happened )

It's also wrong to say that since Republicans are wrong more often, the electorate shouldn't look at policy, and just vote against the Republicans all the time. That is what's happening in the US, whole generations have always voted Republican, and will continue to do so, no matter what their policies, while others have always voted Democrat, even those times when Republicans may have been the better option. This is no doubt, one of the effects ( along with disenfranchised voters who voted against 'traditional' government and politicians ) that helped get D Trump elected; A lot of republican voters simply held their nose and cast a ballot for the Republican party. And look where that got us !
-
Its actually a lot more simple... Americans need to start looking at party policy, not just vote for their grandfather's party. America is so polarized, republicans will always be Republicans and democrats will always be Democrats no matter what policies 'their' party implements, that republicans consider this a good thing, and anything Democrats do a bad thing ( even if good ). The same holds true with good Republican policy. M Romney's health care plan was a 'bad thing' to democrats. Until it was co-opted by B Obama's Democrats. And of course, politicians and Governments are bought and are at the whim of 'big money'. And they're going to bend over backwards to make sure 'big money' gets its rewards for helping elect them.

Vegetarianism/veganism seems to be an affliction of well-to-do people in affluent countries ( and spoilt kids who think they are saving the world ). Poor people in the rest of the world will eat whatever they can get their hands on. Where would you find your vegan staples in sub-Saharan Africa ? The outback of Australia ? the Polynesian islands ? And numerous other places ? The grocery store ? Where would you find the grocery store ?

Not a textbook, Mordred, but his autobiography. I consider J A Wheeler one of the top ten physicists of the past century. I still have it, but I don't recall the exact title; and finding it would be a chore.

You realize that quantum foam is a 'speculation' and only a quantum gravity theory will give a detailed picture at those scales. And my description was NOT of entropic gravity, but of the term quantum foam which you have misused on several occasions on this thread. ( simply google quantum foam to verify the accuracy of my description, which was taken from one of J A Wheeler's books )
-
Quantum foam, IIRC, was a term coined by J A Wheeler, to describe what happens at extremely small separations during extremely small periods of time. In these conditions, uncertainty allows extremely massive virtual particles to appear for infinitely small periods of time, so massive in fact, that Einstein-Rosen bridges ( wormholes ) were created during those infinitesimal time periods. It was this aspect of space-time, that it was 'holed' by a multitude of inter-connecting tubes/bubbles, at this limit, which suggested an analogy to 'foam'. How this does away with the requirement for a graviton in Quantum Gravity, or how it relates to gravity in general is what you need to explain; If you want your assertions ( and associated tangents ) to be taken seriously.
