the entire mass of Jupiter and an equal mass of the sun undergoes fusion

Why would it be an equal mass? What would be the mass of a Jupiter sized hole punched through the sun? Wouldn't the hole be slightly bigger than that due to gravity attracting particles in (though granted not much bigger due to the speed of the event)? How does that compare to Jupiter's mass?

So, you think all fantasies are erotic fantasies?

The Oh-My-God particle was an ultra-high-energy cosmic ray detected on the evening of 15 October 1991 over Dugway Proving Ground, Utah, by the University of Utah's Fly's Eye Cosmic Ray Detector.[1][2] Its observation was a shock to astrophysicists (hence the name), who estimated its energy to be approximately 3×1020 eV or 3×108 TeV. This is 20,000,000 times more energetic than the highest energy measured in electromagnetic radiation emitted by an extragalactic object[3] and 1020 (100 quintillion) times the energy of visible light. Therefore, the particle was an atomic nucleus with a kinetic energy of 48 joules, equivalent to a 142 g (5 oz) baseball travelling at about 26 m/s (94 km/h; 58 mph).[4]
This particle had so much kinetic energy it was travelling at ~ 99.999999999999999999999510% of the speed of light. As a result, its Lorentz factor was ~ 3.2×1011. This is so near the speed of light that if a photon were travelling with the particle, it would take over 215,000 years for the photon to gain a 1-centimeter lead.
The energy of this particle is some 40,000,000 times that of the highest energy protons that have been produced in any terrestrial particle accelerator. However, only a small fraction of this energy would be available for an interaction with a proton or neutron on Earth, with most of the energy remaining in the form of kinetic energy of the products of the interaction. The effective energy available for such a collision is qrt {2Emc2], where E is the particle's energy and mc2 is the mass energy of the proton. For the Oh-My-God particle, this gives 7.5×1014 eV, roughly 60 times the collision energy of the Large Hadron Collider.[5]

I'm too lazy and stupid to try to grab an equation and assume I got the right one. It's going to be one of those 1/[1-(v/c)2] things I think, my brain function has declined too for me to try to get it right. I know I've heard of cosmic rays that have had the mass of something like a tennis ball I think, and that's way more by many orders of magnitude than 'hundreds of times' that I just said.

No: What would accelerate something the size and density of Jupiter to such a velocity without its being disrupted by tidal stresses between the near and far sides of the direction of the force? If it was something the mass of Jupiter with a density that would allow it not to be tidally disrupted, its collision cross-section would be tiny, and you can recalculate your 'effects'. A neutron star with one solar mass is about 10 km across (order of magnitude, don't quibble).

What's the maximum force that would accelerate Jupiter to such a velocity without disruption, and how long would it take to achieve the velocity you're interested in?
