Memory, as the Glue of Society

Our memories are our lives, and a fundamental basis of our culture. Collective memoirs of the past both bind society together and shape our potential future. With our brains we can travel through time and space, calling to mind places of significance, evoking images and emotions of past experiences. It's no wonder, then, that we so desperately fear the prospect of memory loss. See: The Neuroscience of Memory - Eleanor Maguire

What is LROC?

[NASA/GSFC/Arizona State University].
LROC Northern Polar Mosaic (LNPM)

The LROC team assembled 10,581 NAC images, collected over 4 years, into a spectacular northern polar mosaic. The LROC Northern Polar Mosaic (LNPM) is likely one of the world’s largest image mosaics in existence, or at least publicly available on the web, with over 680 gigapixels of valid image data covering a region (2.54 million km², 0.98 million miles²) slightly larger than the combined area of Alaska (1.72 million km²) and Texas (0.70 million km²) -- at a resolution of 2 meters per pixel! To create the mosaic, each LROC NAC image was map projected on a 30 m/pixel Lunar Orbiter Laser Altimeter (LOLA) derived Digital Terrain Model (DTM) using a software package called the Integrated Software for Imagers and Spectrometers (ISIS).

Pricetag on Naming Mars Craters

Recently initiatives that capitalise on the public’s interest in space and astronomy have proliferated, some putting a price tag on naming space objects and their features, such as Mars craters. The International Astronomical Union (IAU) would like to emphasise that such initiatives go against the spirit of free and equal access to space, as well as against internationally recognised standards. Hence no purchased names can ever be used on official maps and globes. The IAU encourages the public to become involved in the naming process of space objects and their features by following the officially recognised (and free) methods. See: Concerns and Considerations with the Naming of Mars Craters

The Outer Space Treaty of 1967

Treaty on principles governing the activities of states in the exploration and use of outer space, including the moon and other celestial bodies.

Opened for signature at Moscow, London, and Washington on 27 January, 1967
THE STATES PARTIES. TO THIS TREATY,

INSPIRED by the great prospects opening up before mankind as a result of man's entry into outer space,

RECOGNIZING the common interest of all mankind in the progress of the exploration and use of outer space for peaceful purposes,

  BELIEVING that the exploration and use of outer space should be carried on for the benefit of all peoples irrespective of the degree of their economic or scientific development,

  DESIRING to contribute to broad international co-operation in the scientific as well as the legal aspects of the exploration and use of outer space for peaceful purposes,  

BELIEVING that such co-operation will contribute to the development of mutual understanding and to the strengthening of friendly relations between States and peoples,  

RECALLING resolution 1962 (XVIII), entitled "Declaration of Legal Principles Governing the Activities of States in the Exploration and Use of Outer Space", which was adopted unanimously by the United Nations General Assembly on 13 December 1963,  

RECALLING resolution 1884 (XVIII), calling upon States to refrain from placing in orbit around the earth any objects carrying nuclear weapons or any other kinds of weapons of mass destruction or from installing such weapons on celestial bodies, which was adopted unanimously by the United Nations General Assembly on 17 October 1963,  

TAKING account of United Nations General Assembly resolution 110 (II) of 3 November 1947, which condemned propaganda designed or likely to provoke or encourage any threat to the peace, breach of the peace or act of aggression, and considering that the aforementioned resolution is applicable to outer space,

When astronauts make such a landing, they shall be safely and promptly returned In carrying on activities in outer space and on celestial bodies, the astronauts of one State Party shall render all possible assistance to the astronauts of other States Parties. States Parties to the Treaty shall immediately inform the other States Parties to the Treaty or the Secretary-General of the United Nations of any phenomena they discover in outer space, including the Moon and other celestial bodies, which could constitute a danger to the life or health of astronauts.  

Article VI
 
States Parties to the Treaty shall bear international responsibility for national activities in outer space, including the moon and other celestial bodies, whether such activities are carried on by governmental agencies or by non-governmental entities, and for assuring that national activities are carried out in conformity with the provisions set forth in the present Treaty. The activities of non- governmental entities in outer space, including the moon and other celestial bodies, shall require authorization and continuing supervision by the appropriate State Party to the Treaty. When activities are carried on in outer space, including the moon and other celestial bodies, by an international organization, responsibility for compliance with this Treaty shall be borne both by the international organization and by the States Parties to the Treaty participating in such organization.  

Article VII
 
Each State Party to the Treaty that launches or procures the launching of an object into outer space, including the moon and other celestial bodies, and each State Party from whose territory or facility an object is launched, is internationally liable for damage to another State Party to the Treaty or to its natural or juridical persons by such object or its component parts on the Earth, in air space or in outer space, including the moon and other celestial bodies.

  
 Article VIII
 
A State Party to the Treaty on whose registry an object launched into outer space is carried shall retain jurisdiction and control over such object, and over any personnel thereof, while in outer space or on a celestial body. Ownership of objects launched into outer space, including objects landed or constructed on a celestial body, and of their component parts, is not affected by their presence in outer space or on a celestial body or by their return to the Earth.

Are Artifacts of CMB Right Next to Me?

 Looking back seems strange to me and that if one is to take such a position then evidence must exist in this very moment?

Models of Earlier Events

This may seem like a stupid question to some, but for me it is really about looking at where I exist in the universe and what exists right next to us in the same space. I am not sure if that makes any sense but hopefully somebody out there can help me focus better.

ESA and the Planck Collaboration

The mission's main goal is to study the cosmic microwave background – the relic radiation left over from the Big Bang – across the whole sky at greater sensitivity and resolution than ever before.

The cosmic microwave background (CMB) is the furthest back in time we can explore using light.

The cosmic microwave background (CMB) is detected in all directions of the sky and appears to microwave telescopes as an almost uniform background. Planck’s predecessors (NASA's COBE and WMAP missions) measured the temperature of the CMB to be 2.726 Kelvin (approximately -270 degrees Celsius) almost everywhere on the sky. 

So with parsing some of these points from the link associated above with picture, I am not sure if my question has been properly asked.

 A discussion about the definition of nothing.

For me then too, I would always wonder about "what nothing is" as that to relates to the question about what can exist right next to me. It was meant to be logical and not metaphysical question, so as to be reduced to those first moments.

***

If BICEP2′s recent result is correct:

” -as big as a large fraction of a percent of the Planck temperature (where the universe would have been hot enough to make black holes just from its own heat) or

– as small as the temperature corresponding to about the energy of the Large Hadron Collider (where it would barely have been hot enough to make Higgs particles)”

History of the Universe- 
“not of the whole universe but rather just the part of the universe (called, on this website, “the observable patch of the universe“) that we can observe today,”

Why is this “observable patch” important and where in the CMB map is this located? As strange a question as this might be, can this “observable patch” be right next to us?

So I am constructing a method here to help us see the universe as if I am on a location within this CMB map.

"The cosmic microwave background (CMB) is detected in all directions of the sky and appears to microwave telescopes as an almost uniform background. " -See: ESA and Planck Collaboration

So of course you look at the map,  and for me,  I wonder where we are located on that map. So with regard to that particular patch what does the background look like?-

"The contents point to a Euclidean flat geometry, with curvature (\Omega_{k}) of −0.0027+0.0039 −0.0038. The WMAP measurements also support the cosmic inflation paradigm in several ways, including the flatness measurement."- WMAP

So such a illustration and my question about our location and where we are in that "all sky map(CoBE, WMAP, and PLanck)" tells us something about the region we are in? Right next to us,  in this map while seeking our placement, I am curious as to what this region looks like in relation to say another point on that map.

We've Come a Long Way

In 2003 the WMAP craft measured the very small fluctuations – about one part in 100,000 – in the temperature of the cosmic background radiation (coloured regions). These fluctuations, which are in excellent agreement with the predictions of Big Bang theory, originated during inflation and evolved under the influence of both gravity and the pressure of the matter–radiation plasma before particles in the plasma recombined to form hydrogen atoms. Buried in this pattern might also be fluctuations from primordial gravitational waves, but to tease out their signature researchers have to map in detail the polarization of the photons as well as their temperature (white lines represent the electric polarization vector). Since gravitational waves produce a quadrupolar anisotropy and therefore induce polarization without an associated temperature fluctuation, they (and only they) are able to generate a polarization pattern that cannot be expressed as the gradient of a scalar.
