Reality Doesnt Exist If You Are Not Looking at It, Quantum

Reality Doesnt Exist If You Are Not Looking at It
Does the world we live in exist? Scientists say no at
least not until its measured anyway, and this would pertain
to small scale. For Australian scientists, recreating experiments
confirmed quantum physics predictions. The existence of
reality is questionable.
If this sounds complex, not to worry. This experiment poses one
simple question: Since some elementary particles act as a particle
or a wave, then when is this classification decided? This question
pushes us to understand how reality is established.
Most people assume that objects such as electrons or photons
either wave-like or particle-like just because thats the
way it is. They think that measurements arent necessary
to come to either conclusion. Quantum theory disagrees and suggests
that conclusions can only be made by measurements taken at the
end of the objects journey.
Andrew Truscott of the Australian National University said:
Reality doesnt exist unless you look at it, and measurements
The experiment in question is the John Wheelers Delayed
Choice experiment, first suggested in 1978. This experiment was
ahead of its time, and not until 40 years later, utilized to its
full potential. Using helium atoms scattered by laser light, scientists
set out to measure the journey of objects in our reality.
Roman Khakimov, a Ph.D. student working on the experiment, said:
Light is more like a wave, so we use atoms, which are more
complex. Atoms have mass and interact with electric fields.
Scientists placed a number of atoms in a suspended state, known
as the Bose-Einstein condensate. After capture, all but one of
the atoms were ejected. This atom was then placed within a pair
of laser beams, to scatter the path of the object, creating a
grating pattern. The process is similar to how light
is scattered when falling upon a grating. After the atom passed
through the first grating, a second grating was dropped, intersecting
the paths, which added destructive or constructive interference.
This result is an action pointed toward a wave, which can travel
both paths. If the second grating is not added, the atom travels
only one path, which points toward particle. This suggests that
the atom doesnt know its nature until it passes through
a second grating.
These experiments prove that particle-like or wave-like
existence is only possible when measured at the end of the journey.
There is no travel from point A to point B. Its not that
Using these theories, we are able to develop lasers, LEDS and
computer chips. This may sound strange, but its just a part
of a quantum theory that governs the small world. Until now, these
pure experiments werent possible. Now, these demonstrations
confirm these ideas work.

NO FEAR ACT!!!!!
By being ONE nobody can change our way.
That's the secret
