Universe
The Universe- people can observe
and study object. Modern
estimation of age Installed in 10
billion years
Where a limit?

The Universe has the end, but is boundless,
twirled round itself. It is impossible to leave
this space as any way will lie on a circle and
again will result in an index point. In the
mathematician there is such concept — a
unilateral surface (Moebius's sheet). It is
closed on herself and no borders has.
Of what consists?


As set of cities make the country so
congestions and supercongestions of
galaxies make our Universe.
The Universe has so-called cellular
structure: on the structure it reminds beer
honeycombs, either a sponge, or soapsuds
where huge cells are formed by congestions
of galaxies.
THE COSMONAUT №1

Gagarin JU.A.quantit of flights: 1 Call sign:
"Cedar" the Touch: 01 hour, 48 minutes. A
world championship: the first cosmonaut of a
planet (on April, 12th, 1961 has made flight by
spaceship "East"); the maximum cargo lifted
into an orbit — 4725 kg; мах. Flight height —
327 km that remains a record till today.

«... The person isn't eternal. But
memory of it can become eternal if he
lived for people. Memory — gratitude
live».
(V.Gagarin from кн. «108 minutes and
all life»)
Galaxy - what is it?

Galaxies represent an enormous congestion
of billions stars and planets. Galaxies can have
the diversified form, for example, the spiral form.
Today scientists know over 6 billion galaxies.
Companions

Before flights of people in space, into an orbit
sent companions. The companion named the first
space vehicle which has been deduced into a
circumterraneous orbit on October, 4th, 1957:
represented a sphere, diameter 58 sm and weight
— 83,6 kg, with the aerials established on it
(them was 4, length 2,4m - 2,9м). In the case
there were radio transmitters which transmitted
signals to the Earth.
The Milky Way


The Milky Way — a small part of one of the
galaxies, consisting of 100 billion stars and
planets. It has the disk-shaped form and is
formed by the "threads" dispersing on a
spiral from the central congestion of
stars.ntral congestion of stars.
Our Sun – one of stars in a galaxy (star
system)he ce
Solar system

Solar system — a tiny part of the Milky
Way. It consists of the Sun and nine major
planets. Each planet moves round the Sun
on an elliptic (oval) orbit. Round the Sun
thousand asteroids — the blocks of ice
covered with a cloud of a dust and gases
rotate also.
Other civilizations

The hypothesis about existence of
extraterrestrial civilizations follows from
representations about naturalness of
occurrence of the person, resulted
occurrence on the Earth to life and its
evolution. If life occurrence, and then —
reasonable life — natural process, means,
similar could occur and in any other place
where there are suitable conditions
Other civilizations
Life in the Universe can have the forms not similar to
the terrestrial. Life occurrence in the interstellar
environment where various organic molecules (оксида
carbon, methyl spirit, formaldehyde are revealed many)
is possible. In a space matter can be formed and more
difficult molecules. Probably that amino acids and fibers
(a basis of a live cage) can arise not only on a surface of
planets
All rather …
It is more than two hundred millions years spends the
Sun to turn back round the Galaxy center. It is socalled galactic year. In comparison with this "year",
existence time for our Earth mankind won't make
also two "days". Usual human life — two "seconds".
