THE SPHERICAL SPACETIME - ALEXIS KARPOUZOS
I. The Question of a Spacetime without Centre From Aristotle to Kant, Western philosophy approached space and time primarily as conditions of the possibility of experience or as properties of reality. In the Aristotelian tradition, space is defined topologically — as the place of bodies — and time arithmetically — as 'the number of motions with respect to before and after'. In Kantian critical philosophy, space and time become a priori forms of intuition, transcendental conditions of all phenomenal experience. Yet in both traditions a common assumption is preserved: space and time are structures that organise phenomena from a — however implicit — centre of reference. Alexis Karpouzos radically challenges this assumption. The Spherical Spacetime he introduces is neither place nor intuition; it is a dynamic ontological structure that refuses every privileged point of reference, every external centre, every principle that precedes the very movement of the world. The question posed from the outset is this: what does it mean to think a spacetime that does not 'contain' beings but is the very manner in which beings are? And what ontological consequences does this displacement carry for the understanding of existence, consciousness, and truth?

Why Solar Radiation Varies: Understanding the Changing Energy from the Sun
What Is Solar Radiation? Solar radiation refers to the electromagnetic energy emitted by the Sun. This energy travels through space in the form of light, heat, and other types of radiation. When solar radiation reaches Earth, some of it is absorbed by the atmosphere, some is reflected back into space, and the rest reaches the surface.
