Russian Deputy PM Dmitry Rogozin wants the UN to take over pondering what to do about the asteroid and meteor threat. Well, at least this threat is real and ever-present.
So, yeah, let’s hand it to the UN. So they can set up a committee (IPEE – International Panel on Extraterrestrial Events?); hold expensive global conferences; have 5-yearly reports half written by pre-grad students; employ oodles of bureaucrats; give more posts to kleptocratic third-world functionaries, and win a Nobel peace prize for nothing.
Or we could actually *do* something about it……

“Twins Paradox
The paradox assumes that light from the clocks is time but it’s not it’s just a record of an event.
Time is just an illusion. there is only the here and now.”
Well, it depends on your definition of time. Einsteins general theory has Time as part of the fabric of Space – Spacetime – and the two are inseparable. As you move through space you also move through time. To be exact, if you move 186,000 miles you would gain a second of time. If you could move at the speed of light, you would gain a second for every second of travel, so that your clock would stop.
I agree that there is only the here and now. Otherwise you would be able to jump backwards and forewards in time. Although you can travel into the future, you are not jumping into the future as in Doctor Whos Tardis, but simply contriving to make your time pass more slowly than the rest of us.
Nevertheless, certain aspects of time are real. Entropy increases from moment to moment in any closed system – the arrow of time – which makes the macroscopic world rather more time constrained than the quantum world, where time is reversible. Also, things move at predictable rates and this is a measure of the uniformity of time. If this were not so, physics would be impossible, as objects would move at random and unpredictable rates for no apparent reason.
When I look at myself in the mirror, I would love to believe that time is an illusion, but alas, the face looking back at me begs to differ.
I wish I had the patience displayed by many on this site, when dealing with Progressives and Alarmists, however I simply don’t. Last night I felt the need to blow off some steam, and wrote something called, “A Rant: The Silent Sun.” I likely deserve a scolding, but some may be amused:

John another;
I am trying to find articles from an either Scandinavian, Icelandic, Western Canadian or Washington State biologist who had found a thermometer in some type of mussels and, unlike Briffas trees, showed no divergence problem.

John,
Well said. Unfortunately those in the media continue to confuse things. Watching the Match Play Golf Championships yesterday, one of the correspondants (I believe it was Jimmy Roberts) referred to the snow that delayed play the first day as “due to the climate that day”. Sad.
Now the only thing I would disagree with is this statement:
“I live pretty modestly by American standards, and it does offend me a bit to see suburbanites driving H2s and monster pick-ups they do not need.”
I really wish you had said “that I believe they do not need”. Small point but many of us cringe at the thought of someone else dictating what we want, need or should have.

BTW, I think the first measurment of time dilation was in the 1960s when people flew an atomic clock around the world and it came back with a lagged count.
As the clock was going round the world, one side of it would have travelled further than the other
therefor it would be different ages on either side.

I need some help with this: More snowstorms should NOT be “what is expected” with global warming. Can someone here please provide the specific and correct details as to what is going on when excess water vapor in the atmosphere precipitates out as snow rather than as rain?
The context here relates to the weather events of recent large snow storms being, according to the alarmists, “exactly what they expect” (sure!) because of global warming. These newly arriving special pleadings contend that a warmer Earth causes more evaporation, more moisture in the atmosphere, and thus more precipitation, thus more snow in the winter. If we provisionally accept the increased moisture claim, the further implication seems to be that the only difference between snow and rain is like 31 degrees instead of 33 degrees.
We never see skeptics claiming that a heat wave (weather) is indicative of global cooling, but the alarmists don’t mind (or have to, I guess) claim a snowstorm indicates global warming; counterintuitive and convoluted. Exactly what is it that IS wrong with the alarmists’ argument? What physical laws are they invalidating this time?
I cannot find or get my mind around exactly what happens during an evaporation/condensation/freezing event (ocean water to snow), but I feel the “gotcha” must be the energies associated with the phase changes. With evaporation-to-rain, there are two exchanges of the same amount of latent heat of evaporation: one in, one out. With the evaporation-to-snow process, there is the additional heat of fusion that must be taken up by the surroundings when snowflakes form. The heat of fusion (or melting) is smaller than the heat of evaporation (or condensation), but still huge relative to heat that causes temperature changes. Those peaky phase changes. Further, the taking up of heat seems necessarily to be facilitated by a COOLER Earth, certainly not by a warmer one.
Popular presentations of weather treat evaporation, rain, and snow as something the atmosphere does because it “feels like doing it”. Dig deeper and your own intellect (even with a grounding in physics) may keep asking deeper questions. Simply as a matter of education, what is really going on? Thanks for any insight.
Dear Lance Wallace,
I beg to disagree that the Fourier expansion fit for the CO2 is an elephant. I have checked that by using the 20 years between 1974 and 1994, one gets a virtually identical shape of the seasonal CO2 as from the years 1994-2013 and this shape is very far from a simple cosine and shows quite some structure. A good theory of vegetation should be able to reproduce this function.

Raspberry, Einsteins’s paradox is not considered a paradox among the folks who operate the satellites overhead as satellite GPS clocks in orbit have to adjust precisely to what the theory of relativity dictates. …
Ric Werme says: February 23, 2013 at 9:52 pm
… BTW, I think the first measurement of time dilation was in the 1960s when people flew an atomic clock around the world and it came back with a lagged count. The GPS satellites in their 12 hour orbit make it easy to observe. Note that a satellite orbiting the Earth is constantly accelerating toward the center of the planet, so acceleration may still be important.
The GPS satellites operate in a rotating reference frame with regards to each other, and rotating frames have special rules. The adjustments they apply are to correct the Sagnac effect.
While you get the time dilation and mass increase, the speed of light is not constant in a rotating frame (nor even a speed limit), therefore you don’t need or get Lorentz contraction. Relativity of simultaneity doesn’t apply in the overall rotating frame either, as it would allow backwards time travel.

Vince Causey, Laurie Bowen,
Yes, time itself slows, but only as measured from someone else’s frame of reference. The twin who returns has to accelerate to do so, and acceleration moves you from one inertial frame to a different one. It is this change of reference frame where the twins’ time difference manifests itself.
@ur momisugly Caleb ,thats a polite way of saying” its the sun stupid “.
Nice rant, civil too. I too was initially confused by Climatology (TM the religion) willingness to pretend that history never happened. For who in their right mind, would deliberately tell lies so blatant that any adult could refute? Past cycles of weather are writ large in our recorded histories,in the very stone underfoot, there is nothing new about todays weather, so what was going on?
I thought, they can’t be serious,this BS will never sell.
I forgot the 5 laws of human stupidity.
Progressives abandoned liberal as the name sank in public esteem.
Progressive debt, progressive reduction of wealth, progressive loss of freedom, that label will be abandoned soon enough, then they will call themselves internationalist or global citizen.
Course a parasite will let you call it anything you want, as long as it gets to feast at your expense.

“Lubos has just produced a nonlinear fit to the carbon dioxide curve at Mauna Loa:
http://motls.blogspot.com/2013/02/mauna-loa-carbon-dioxide-fit.html
A mere 6th-degree Fourier expansion with 12 parameters (6 for sines, 6 for cosines) fit by nonlinear approximation. Von Neumann’s elephant will not only be wiggling his trunk, but his ears, tail, and balancing on one leg simultaneously.”
He’s just analyzing the spectral composition of the seasonal signal after subtracting an exponential trend. The criticism is silly.

and all others who may have commented on the Einstein’s Twin Paradox. As a mere down to earth engineer I was somewhat troubled by the Newton – Einstein gravity theories ‘conflict’. Just as an exercise I made an attempt to join two together, which appear to be possible if gravity field has a wave property ‘similar’ to an electromagnetic field spaning the cosmos.
Unintentional consequence is that there is no need for the existence of ‘dark matter’, the Universe may not expand for ever, i.e. fly apart, and gravitational wave can not be measured since its wavelength is equal to diameter of the existing Universe. Pretty fundamental if true but is it ? and if not, why not?
Here are details of my simple calculation
http://www.vukcevic.talktalk.net/UC.htm
Don’t take it too seriously, but by all means have a go at it.
-96.1F was the record before (-71.3c) so not sure what to make of it of the claim above. (confusion)

But these distances you speak of are relative, are they not. The moving twin ‘sees’ a contracted distance and the Earth bound twin ‘sees’ the proper length. The speed of light is constant no matter what the relative speed of the inertial frames (the second postulate of SR). The dilation of time happens as the length contracts, hence relative.
Isn’t the “paradox” that the difference in apparent aging of the twins is unintuitive, but is mute if you accept the consequences of Special Relativity.
You cannot combine Newton and Einstein in terms of gravity. Newton’s a priori assumption is that time is absolute as is space, but Einstein’s theory of relativity takes space and time as interrelated, hence space-time. The consequence of this is that an accelerating frame of reference is identically similar to a gravitational field.
In terms of relative motion Einstein becomes Newton when the speed (velocity) of the inertial frame is much much much less than the speed of light.

The Earth moves away with light speed from the rocket so time on Earth comes to a standstill. In the rest of the galaxy as well. While the twin in the rocket is at standstill and therfore ages normally.

“Time is just an illusion. there is only the here and now.
Time is distance. Everywhere you see in the universe is in the past relative to you. So if you travel towards a planet you will be travelling into its future as you are in its past at the moment, and the planet you left will move into your past. Your local time will not change as it is relative to you.”
———————————————-
Well said… the concept of time is abstracted from the observed persistence of existence of the eternal now, and is based on the measurement of relative changes of events in 3D space.
(and btw, 3D space is also a concept, one based on the measurement of finite volume abstracted from infinity),
A bit of Zen understanding is a great help to see that all concepts used to represent reality are not actually reality, merely mental constructs to stand for that reality, and that only when the mind is still and free from conceptualization will reality be directly present to the mind.
