Abstract
Recent observations on Type-Ia supernovae and low density (
Ω
m
=
0.3
\Omega_{m} = 0.3
Ω
m
​
=
0.3
) measurement of matter including dark matter suggest that the present-day universe consists mainly of repulsive-gravity type `exotic matter' with negative-pressure often said `dark energy' (
Ω
x
=
0.7
\Omega_{x} = 0.7
Ω
x
​
=

). But the nature of dark energy is mysterious and its puzzling questions, such as why, how, where and when about the dark energy, are intriguing. In the present paper the authors attempt to answer these questions while making an effort to reveal the genesis of dark energy and suggest that `the cosmological nuclear binding energy liberated during primordial nucleo-synthesis remains trapped for a long time and then is released free which manifests itself as dark energy in the universe'. It is also explained why for dark energy the parameter
w
=
−
2
/
3
w = - {2/3}
w
=
−
2/3
. Noting that
w
=
1
w = 1
w
=
1
for stiff matter and
w
=
1
/
3
w = {1/3}
w
=
1/3
for radiation;
w
=
−
2
/
3
w = - {2/3}
w
=
−
2/3
is for dark energy because
"
−

"
"-1"
"

is due to `deficiency of stiff-nuclear-matter' and that this binding energy is ultimately released as `radiation' contributing

, making

/

w = -1 + {1/3} = - {2/3}
w

. When dark energy is released free at

Z = 80
Z

,
w
=

/

w = -{2/3}
w

. But as on present day at
Z

Z = 0
Z
=

when radiation strength has diminished to

w = -1 + \delta{1/3} = - 1
w

. This, thus almost solves the dark-energy mystery of negative pressure and repulsive-gravity. The proposed theory makes several estimates /predictions which agree reasonably well with the astrophysical constraints and observations. Though there are many candidate-theories, the proposed model of this paper presents an entirely new approach (cosmological nuclear energy) as a possible candidate for dark energy.Comment: 17 pages, 4 figures, minor correction
