Medical practitioners have been aware of the placebo effect for decades now.
Some administer it. Still some attempt to explain it as a biochemical effect.
However, no one knows exactly what it is and how it comes about.
Cosmologists wrack their brains over an explanation to the horizon problem.
Some come up with this explanation of inflation: “You can solve the horizon problem by having the universe expand ultra-fast for a time, just after the big bang, blowing up by a factor of 1050 in 10-33 seconds. Inflation would be an explanation if it occurred.”
Still, no one knows what could have made that happen. Fact is ‘nothing can travel faster than the speed of light, so there is no way heat radiation could have travelled between the two horizons to even out the hot and cold spots created in the big bang and leave the thermal equilibrium we see now.’
Homeopathy preparations are made by dissolving solutions such as histamine, and then diluting this “mother tincture” in water again and again.’ No matter how further diluted the solution is, ‘it is still imbued with the properties of the remedy.’
There is more stuff out there in the universe than we can see.
However, nobody could explain what dark matter is. ‘Astronomical observations suggest that dark matter must make up about 90 per cent of the mass in the universe, yet we are astonishingly ignorant what that 90 per cent is.’
Tetraneutrons are four neutrons bound together in a way that defies the laws of physics.
Based on standard model of particle physics, tetraneutrons simply can’t exist.
There are obvious reasons to doubt their existence. ‘If you tweak the laws of physics to allow four neutrons to bind together, all kinds of chaos ensues.
It would mean that the mix of elements formed after the big bang was inconsistent with what we now observe and, even worse, the elements formed would have quickly become far too heavy for the cosmos to cope.’
