4. Mercury’s
Precession
A compelling piece of evidence for general
relativity is the Mercurian orbit. Mercury, the
closest planet to the sun, should revolve around it
just like any other planet. The picture shows the
expected orbit that Mercury should follow yet it
doesn’t as we can see. In general relativity, this
remaining precession, or change of orientation of
the orbital ellipse within its orbital plane, is
explained by gravitation being mediated by the
curvature of space-time.

5. EXPANSION OF
THE UNIVERSE
In April 1931 report to the Prussian
Academy of Sciences, Einstein finally
adopted a model of an expanding
universe. In 1932 he teamed up with the
Dutch theoretical physicist and
astronomer, Willem de Sitter, to propose
an eternally expanding universe which
became the cosmological
model generally accepted until the
middle of the 1990s.

6. Expansion of Space
explained
Albert Einstein stated in the “Special Theory of Relativity” that the laws of physics are the same for all
observers, and the speed of light in a vacuum never changes regardless of the speed of the observers.
As a result, Einstein found that space and time are not independent of each other but are intertwined space-
time continuity. This theory suggests that the moment events occur for one observer may also occur at
different moments for other observers.
While working on the “General Theory of Relativity”, Einstein realized that giant objects cause distortions
in the space-time fabric. You can compare it to a trampoline with a large weight on it.
The weight placed on the trampoline will press down on the trampoline fabric and cause it to stretch.

7. General Lensing And
Relativity HOW?
The gravitational lensing
experiments have provided
conclusive proof that dark matter
really does exist – in some form.
However, it is still another form of
indirect observation. According to
NASA, the new cutting edge in
astronomy builds on the
observations of gravitational
lensing by looking for new ways
that dark matter might be observed
directly, like gamma rays released
by colliding dark matter particles.

GRAVITATIONAL LENSING IN
GENERAL RELATIVITY, IS
THE PRESENCE OF MATTER
(ENERGY DENSITY) THAT CAN
CURVE SPACETIME, AND THE
PATH OF A LIGHT RAYS WILL BE
DEFLECTED AS A RESULT. THIS
PROCESS IS CALLED
GRAVITATIONAL LENSING AND,
IN MANY CASES, CAN BE
DESCRIBED IN ANALOGY TO
THE DEFLECTION OF LIGHT BY
(E.G., GLASS) LENSES IN
OPTICS.
