That's very good from an engineering perspective. But think of it from the more fundamental view of charged particles or objects. They attract or repel each other toward or away from the center of gravity of the interacting system. A glancing blow imparts rotational inertia to the objects. Because of the balanced nature of forces it would seem that all force in the universe is completely balanced and the universe should be symmetrical until we remember that some of this is bound as rotation.

Set yours Time pods and Clocks...Spring!!!
Set yours Clocks and Time Pods ahead 1 hour late Saturday...
Quoted:
Don't forget to set your clocks an hour ahead this weekend. On Sunday at 2 a.m. daylight saving time goes into effect.
This is only the third year that daylight saving time has begun the second Sunday in March. For years, the first Sunday in April was the day the clocks and other time pieces were set forward.
Daylight saving time continues until 2 a.m. Sunday, Nov. 1.
The moving forward of the daylight saving time start date was part of the federal Energy Policy Act adopted in 2005.
Thus, on this Sunday evening you will have one more hour of sunshine than on Saturday.
Daylight savings time first began in the United States during World War 1 in an effort to conserve fuel used to generate artificial lighting. It was suspended after the war ended, but was restored again during World War 2. In the years that followed, some states and communities continued to have daylight savings time, but the time periods varied.
Under the Uniform Time Act passed in 1966 any state that adopted daylight savings time would have to follow the dates set by the federal government.
Today all states in the nation except Arizona and Hawaii observe daylight saving time.
Many other nations, including the European Union, for instance, observe daylight savings time during a period beginning the last Sunday of March and extending until the last Sunday of October.
Most of Mexico and all of Canada have daylight savings time as do Russia and China.

Re: Set yours Time pods and Clocks...Spring!!!
Well, Arizona may be smart not adhering to the Daylight Savings Time. For 4 months now only out of the year, you are not on Daylight Savings Time. I would rather be on regular time all year around actually.
And what happened to telescops? All this computer stuff they include and now, it just seems like crap to me. I guess it is good that my 30 year old Cave Astrola Stand for my 10" telescope still works along with the telescope. I don't need a computer to set up a telescope and observe the Heavens. I need a star chart and line of sight to it. Funny how some of these manufacturers thought they make money on making telescopes. There are only 3000 amatuer astronomers about in the USA anyway. And some of the old manufacturers I guess have died recently. It is a shame. Dobsonian telescopes are great for low-cost - nudge, nudge, nudge the telescope all night long. But then, without any effort I can at least set up my telescope close enough to North to track for a least a couple of hours on its own and keep the object in the field of view. Well, back to getting some parts again, and some eyepieces. I fail to see why I would want to spend money on half of what they make in that industry in any shape or form. Now it seems to be Russian made mirrors, and all they want to do is add the corrector plate to the front of even a Newtonian telescope and make it into a kind of Shmidtt-Casssegrain type Makatov-Cassegrain type Newtonain telescope. And yes, Dobsonians are cheaper, and not too bad to move around, but well, whatever those manufacturers did to the German Equatorial Mount has not really improved anything. A mount that can only handle a 45lb payload with the type of telescopes they are making. My telescope weighs 60lbs to start off with, and has a mount that can hold at least a 40lb counterweight.
And the prices of some of this stuff. Anymore I get that 11" Celestron for around $2600 but geezes at Jim's Mobile, he as a dobsonian made into a sort of equatorial mount (for a large telescope) that cost - can you believe this - $15,900 dollars. Some of the prices I saw were up to $32,000 for a telescope. (of course, you can always buy cheaper, and end up building your own dobsonian at even a less price with a little bit of work and learning).
Well, back to getting some eyepieces for those have also gone up - way up in some newer ones - from like say "Nagler" type eyepieces.
Well, that is another subject, but when you look at the stars and galaxies and nebulae, you are also looking at light that is from the Past.
(I have been out of it for awhile - for various reasons - but if everything else is going to go up - all I need is my battery (or not) to drive my telescope, and the lights - off!)

Re: Set yours Time pods and Clocks...Spring!!!
in your question it depends...
mr. wolf, mass is a type of energy and you can use DE (like mr. darby has said) to measure it.
time in terms of mass, time becomes a lack of energy, and in the inertial frame of reference, time is energy. you notice this when mass gains more energy as it approaches c.

Re: Set yours Time pods and Clocks...Spring!!!
I guess they still sorta make a telescope. But, here is the trick.

All this error correcting optics can't be seen if you read a little and get some other parts - mainly a little bit longer telescope tube, a 4-vane spider for the secondary mirror that can be moved further towards the front (or the mirror further back towards its end) and instead of using the usual 2.6" secondary sized mirror (ellipse but when angled at 45 degees it becomes - what - a circle shoving the light up to the side of the telescope into the focuser) for like a 10" or even a 2.14" secondary mirror - a 1.52" secondary mirror (or a 1.83" secondary if you are blind and like a bigger brighter low powered field) or even down (if buying a really low-profile focuser - where the eyepiece is focus with part of it inside the tube but not down to the mirror - about an inch inside usually) with par-focal eyepieces (all focus at about the same distance) to a 1.3" secondary mirror - say for really really fine field of view or planetary to show really really really fine detail -- the star images will all be smaller - won't even see the coma in a mirror - your eye ain't that good and well photography is another subject through a telescope) and less obstruction of the main mirror - results in a really really really really really fine detailed image through a telescope. Combined with a good couple of (high and low power) eyepieces - you actually want to look through the telescope instead of being sidetracked with fancy promises - of precision mirrors - duh - only if both are 1/30 wave of light - which usually they are not - combined - only 1/10 wave of light and some mirrors better than others - and other things you just do not need. Try a star chart and citing down the tube with just a reticle finder - eyeball it.
Well, like anything else, others always make improvements just on their own.
Like being at the Texas Star Party and viewing all those big mirror Dobsonians, but as of yet - the time my little 10" mirror was looking at Saturn at 538 power down there. Oh, and near a few days old moon (3 days old) using 827 power (although it was getting a milky-appearance) like being only 300 miles above the surface of the moon.
A few adjustments - allowing for traveling of the mirror up to 2-3-4 inches and a smaller secondary to a closer focuser - all allow with the counterweights in the right place - a telescope to take photography through - an a visual telescope that knocks other made telescopes from a manufacturer - silly.

Re: Set yours Time pods and Clocks...Spring!!!
You just gave me an interesting idea, though it's a little off topic. What if we constructed a huge retroreflective mirror and launched it to space, positioning it, say, a light-day away from earth? We could use a telescope to view the previous day by viewing the reflections from the mirror. Of course, it would only give a moving window to the past beginning when the mirror reaches its destination. What do you think?

Re: Set yours Time pods and Clocks...Spring!!!
Yes, that was mentioned in the book by J. Richard Gott about "Time Travel, the physical possibilities in Einstein's Universe" that came out about the summer of 2001. Except the mirror was 10 light-years away and so 10 years out and 10 years back you view the Earth as it was 10 years ago but 10 years in the future (or something like that - have to check the book - has ideas like that to write about 'time travel').
Same as the other sizing example of the local system here of the Solar System. Take a Sun whos size is about the same as a basketball, then the Earth would be about a pin prick away at 1/10 inch, with Pluto being even smaller at about 40 feet away from the basketball-sized Sun, but then the neareast star to us (Alpha Centauri) would be over a mile away from that exhibit in say a basketball court gym held say on Astronomy Day sometime in April or May.
So, it is merely not "Space" travel to go anywhere in the Universe, it is "Spacetime" travell and maybe more "Time" than "Space" travel.
But never-ever send your mirror to Clausing's in Chicago, I don't know what kind of coating on the mirror it is, but it is not alumimium with magnesium overcoating, it is some kind of yellow-green whatever it is yucky type coating. Geeze, well, work to do. Got to find a low-profile focuser or fix mine (home-made sorta) and get an enhanced coating on my mirror. Sorry, compared to 30 years ago, when I bought mine (1978) they sure do want a lot of money for those equatorial mounts nowadays - geeze. Computer lining-up, well perhaps, if anyone could afford it, but then just give me my old Mount and rotating tube telescope (rings on it so you can turn the eyepiece to where you want it) and stick an eyepiece in - and good ol' Sky Atlas 2000) and hunt for the objects - it not as hard as the "just sit there and let the computer mount find it type whatever it is they sell nowadays as being a hobby to do thingy") because that is half of it - "Knowing Your Way Around the Sky" type of activity. Oh, well....................I guess that is why Amatuer's Build their own telescopes also for the hobby. Viewing the stars can take all of your life and then far into the future. And all you had to do was set it up and take it down and take a little care of the shafts so they do not rust, and it will last longer then you will - for the most part. Except for the rain, rain, and more rain which is happening now for the last couple of days - the sky clears and the viewing usually is better because all the dust in the air and such came down with the rain (or is that acid rain) well, usually you can even drink it after checking it and such if you caught it in a barrel.

Thanks ray i do understand why you are scolding me,do not worry about it,i am very aware of my previous posts,but hey brother i just think we need some more serious threads over here because as far as i can see day by day on timetravelinstitute is a bunch of annoying Tters fakers or Tters spammers or Tters trolls whom only come post 1,2,3 o 4 times and then just dissapeared with the wind.I don't mean to be rough but hey that is only my humble opinion,i need substance in my daily basis so therefore i can have a very happy and interesting life every single day,well i hope we might get some real "action" in the near future,
