In the mathematics of Einstein's Theory of Relativity, black holes are predicted and astronomers have proven beyond all doubt that they exist. The centre of our own galaxy harbours one of these monstrosities and so do nearly all galaxies observed. In the same mathematical models which predict black holes, there are predictions for entities which … Continue reading White Holes
Around the middle of the 19th century, mathematics was undergoing a revolution. Certain Classical notions were being overturned and in their place, something altogether stranger was beginning to appear. Where previously it had been based around observations in reality, maths was now becoming its own language which it was hoped could describe and even anticipate … Continue reading Six Impossible Things Before Breakfast – The Physics of Alice in Wonderland
