Welcome to Greenwich
Welcome to Greenwich, home to a World Heritage Site, Europe’s
most successful entertainment arena, Britain’s first urban cable car,
London’s oldest Royal Park and the place where hemispheres meet.
Internationally recognised as the home of time, Greenwich is also
where to find the Prime Meridian of the World. Every place on Earth
is measured from here.
The National Maritime Museum, Queen’s House, the Old Royal Naval
College, Greenwich Market and Cutty Sark dominate central
Greenwich and the view across London from the Royal Observatory
in Greenwich Park is outstanding.

Information about The Royal Observatory - The Royal Observatory Greenwich is the home of
Greenwich Mean Time and the Prime Meridian of the World. It is also home to London's only
planetarium, the Harrison timekeepers and the UK's largest refracting telescope.
This conflicts with Space because it shows that it has UK’s largest refracting telescope which can look
into Space.

The Planetarium – What is a Planetarium? –
Think of a planetarium as a tour bus of the Universe taking you on
amazing journeys to explore and experience the wonders of the
night sky. Combining real images from spacecraft and telescopes
with advanced CGI, all projected onto a fully immersive dome, the
Planetarium can fly you into the heart of the Sun, transport you to
distant galaxies, show you the birth of a star or land you on Mars.

Greenwich Mean Time –
Royal Museums Greenwich is a group of world class museums
incorporating the National Maritime Museum, Royal Observatory,
Cutty Sark and the Queen's House, situated at the heart of the
Maritime Greenwich World Heritage Site. Royal Observatory
Greenwich is the home of Greenwich Mean Time and the Prime
Meridian of the World.
Stand with a foot in each hemisphere at Longitude 0°0' 0” in the
Meridian Courtyard, marvel at the scientific discoveries that changed
our understanding of time and space and see how the Astronomers
Royal used to live and work at Sir Christopher Wren's Flamsteed
House.
Enjoy a spectacular cinematic experience at London's only
planetarium, with breath taking tours of outer space guided by real
astronomers.
The Prime Meridian Line – What is a Meridian? – What is a Prime
Meridian?
A meridian is an arbitrary north-south line used by an astronomer as
a zero point from where to take measurements. By comparing
thousands of observations taken from the same meridian it is
possible to build up an accurate map of the night sky.
The meridian line in Greenwich represents the Prime Meridian of the
world, Longitude Zero (0° 0' 0"). Every place on the Earth is
measured in terms of its angle east or west from this line. To stand
astride the line is to have one foot in the eastern and one foot in the
western hemisphere of the earth – just as the Equator divides the
northern and southern hemispheres.
The Prime Meridian at Greenwich passes through a massive special
telescope called a transit circle. The transit circle was built by Sir
George Airy, the seventh Astronomer Royal, in 1850. The cross-hairs
seen in the eyepiece of this transit circle define Longitude 0° for the
world.
The 'universal day' is measured from the Prime Meridian. It is the
average of a year's worth of 'natural' days and is a scientific time
scale used irrespective of time zones.
Emmanuel Cant – View on Space and Time
Two aspects of Kant's views on space and time are immediately
evident: they are widely regarded as central to Kant's so-called
critical philosophy, and there is no consensus on how they ought to
be characterized and explicated. The overarching goal of this entry is
to bring some clarity to Kant's views by situating them historically
and philosophically within the milieu of some central debates
concerning space and time in the early modern period, especially the
rich century between the first edition of Newton's Principia in 1687
and the publication of the second edition of the Critique of Pure
Reason in 1787. But the difficulty of comprehending Kant's views
gives interpreters a reason to place a greater emphasis on context—I
will especially highlight Kant's reactions to his most significant
predecessors in this area, Leibniz and Newton. The focus throughout
will be on Kant's magnum opus, the Critique of Pure Reason
(1781/1787). Following tradition, and to some extent Kant's own
lead, the focus will also be on space and on our representation of
space, although parallel points concerning time (and its
representation) will sometimes be indicated.
Conclusion – In my opinion Space and Time are two of the same, the
collaborate like no other thing.
