It takes a lot of pressure and the right electrical conditions.

Did you know that the chamber pressure generated during a rifle firing is three times as high as 'challenger deep,' in the Mariana trench? Rifle rounds travel 800 m/s and faster, and ICBMs travel faster than rifle bullets. We would never see it coming. Or they. Whoever---or in this case, it's definitely a
whomever, because they are the ones getting something done to them. They or we will not see it coming. Probably if you do see it, you're shortly dead, incinerated into ash instantly.
When you say electrical, what do you mean? Do you mean that there must be a net charge present in order to generate the characteristic radioactivity that each element naturally possesses, or just that the fundamental force electromagnetism is involved, along with the pressure?
I know of the following distinct ways that one part of the universe can attract another part of the universe. Gravitation. Van der Waals forces. Electrical attraction. Magnetic attraction. And of course, whatever of the nuclear forces is able to keep protons RIGHT NEXT TO EACH OTHER. I don't know if you've ever calculated the force that would be required, just to counteract the electrical repulsive force, which is like pressure, occurring in every nucleus in the universe besides hydrogens, and then ponder how much additional force is required to make them stick together so tightly that it takes a NUCLEAR REACTION to separate them.
So five. Five distinct ways in which different parts of the universe can be attracted to one another. And I don't know about you, but I find myself thinking about gravitation more than any of them, mainly I suspect, because it's the only one with something called 'dark energy,' and then an entirely distinct other thing called 'dark matter,' and it's captured a part of my imagination.
Gravitation as Newton and Einstein conceived it require both dark matter and dark energy in order to have explaining power, but there is so much dark matter and dark energy required, that our gravity determinations only explain 5% of what we see in the night sky of outer space. And this stuff concerns how galaxies are orbiting each other. Galaxies are the largest objects we have identified, which means mainly they have a lot of mass, and so when two galaxies are orbiting each other, they ought to orbit even more predictably than the planets in our own solar system do, but galaxies do not do that, which means that if it is due to matter, then 95% of the matter in galaxies is hidden from our ability to detect it with anything but gravity calculations, that we are getting wrong, as proven by the galaxies orbiting patterns we're observing.
It's not exactly true that 95% of the universe is dark matter, or of a galaxy. There's more dark energy than there is dark matter. But dark energy still has mass, or something, I don't know---I don't know how or if they invoke the E = MC-squared, energy-mass equivalence, in saying that dark matter is 20-something percent, and dark energy is 70-something percent, and what we detect constitutes only 5%. Whatever it is, the impression is that there is more mystery with gravity.
Also, does relativity actually nullify gravity, that 'gravity' is 'just' the bending of 'space-time,' and so it's not a force at all? Even though it's what keeps planets from hurtling off into space, relativity says, 'NOPE. No force involved. 'Bending space-time.' I don't buy it. There's a force involved there, and if you won't admit it's force acting on the planet, at least prove that it's altering the road that the car's on, if it's not affecting the car directly, which is what I'd expect, if you told me the earth is a ball that's whipping around and around and around the sun, year after year after year after year, but it will never fling off into outer space. And it's not physically connected to the sun, except by 'space-time.' Doesn't that make 'space-time' a type of physical tether? 'Space-time' must make what we've been perceiving as distinct objects, one object. We can't see the 'space-time' bit, but if it's really there, then 'gravity' is a space-time tether. They are connected together, the way they're connected is called 'space-time.'
Space-time warps in the presence of mass. Space-time together with the objects we see in the night sky, constitutes an object, or a piece of an object; not multiple objects. The earth stays in orbit not because of a force, but because that's how the space-time is connecting together the sun and the earth, and the moon and the earth too. It's all one object.
What's the mass of space-time?
