If we take a charged particle say..protons..highly energetic and with extreme speed we fuse it with U-253 at extremely high pressure ant temperature will it release an extraordinarily high energy radiations which can generate energy equivalent to the energy released during the Big Bang??

A couple of points here...fusion is the process where energy is released by combining, or fusing particles to create a larger nucleus, as is done when protons collide and fuse to form helium nuclei in the sun. Fission is the process in which energy is released when a larger nucleus splits into smaller fragments.

Uranium does release energy, but by fission, not fusion. The isotope of uranium that is most efficient for releasing energy by fusion is U-235(I think you have a typo in your question).

Protons are typically not used to initiate the fission, since the protons in the uranium nucleus will repel the incoming proton, rather, neutrons are used to initiate the fission since they do not experience an electrostatic repulsion.

The amount of energy that is released is significant, but no where near the energies involved in the big bang. Each nucleus will release a certain amount of energy / nucleus (called the binding energy); the amount of energy that is released is the product of the binding energy/nucleus times the mass of material fissioned or fusioned.

As others have noted, lighter elements give a better"Bang/buck", in other words, you can get more total energy out of the fusion of lighter elements than the fissioning of heavier elements.

A very interesting book on how this works and its implications for nuclear weapons is John McPhee's "Curve of Binding Energy". It is written for a general audience, and has a lot of good science and history in it.

The "Big Bang" energy levels were much higher than those associated with fusion or fission of atomic nuclei. So the quick answer to your question is "No".

Fusion of any element heavier than Iron requires energy input. Most such combinations are unstable and will immediately break down by the fission process to release that same energy.

There is a very high activation energy barrier to the proton fusion process. You could bypass this by using neutron radiation instead of protons.

Antimatter annihilations would be an even better source for higher energy processes. You could make small amounts of anti-protons by colliding your high energy proton stream with a suitable target material and redirecting the anti-protons with suitable electromagentic fields.

Probably not, since U-253 doesn't exist, Uranium having 3 isotopes u-238, 235, and 234.
And since the Big Bang contained all the energy and mass of the Universe, it seems hardly likely that ANYTHING at high pressure and temperature will be equivalent.
Where do you get these questions?

it's unlikely that the two would fuse. if you tried, particles on the uranium atom would fly off, in which case it would be a fission reaction -- something we can already do (nuclear bomb). theoretical fusion combines to atoms, not an atom and a proton. when two atoms are fused, the difference in mass would be greater and the amount of energy released would be greater (by the equation e=mc^2). still, it wouldn't be anywhere near the amount of energy released during the big bang.

The lighter elements are better suited for fusion. The heavier elements like fission. It switches right around Iron. Some of the very massive stars have iron cores and we are yet to find a star with anything heavier than an iron core. Our sun has a helium core due to it is not big/hot enough to continue to fuse helium.
So to answer your question it will be extremely difficult for fusion to occur in your scenario.

the first thing is U253 exists.

after this if want to get same amt. of energy as released in big bang then u got go deep into the concepts of nuclear fusion

it comes under a subject in physics called - quantum chromodynamics.

Only in fusion such an amt. of energy is released. so its not possible with fission or bombarding charged particle.

actually the nuclear reactions hardly depend on charges .
they depend particles called quark.

so thats what i it deals with quantum chromodynamics.

not like big bang as it was a different phenomenon but it is not only proton but neutron can also give same results,but not that much energy may liberated.Recently a new substance "ANTI-MATTER" is under research,it is said that a gram of anti-matter can liberate energy equal to 10 hydrogen bombs. Science is really amazing but it shouldn't be used in destruction,its not safe producing such substances like anti-matter.

U mean U-235 ???
Fusion reaction = combinating reaction produces a "big" and "more stable" nuclear from "small" nuclears.
Uranium 235 is too big and heavy to engage in fusion reaction. According to Mendeleev rule, Uranium is a heavy and unstable element. So if it engaged in the reaction, what kind of "more stable" nuclear would it create ??
And I think the answer is NO

no it isn't possible to produce so much energy,

also the fission starts after collsion of a neutron bombarded over uranium usually by a neutron gun.

also,if we could develop fusion reactors, even after that it isn't possible to produce a energy equal to BB.
