YouTube. YouTube. Saint, Peace Seeker, Hero by Turns. HODAL, India — Barreling down a sizzling-hot road, in a cloud of diesel fumes and dust, Ludkan Baba is on a serious roll.
He lies flat on the ground, turning himself over and over like a runaway log, limbs flailing as he bumps across potholes, splashes through mud puddles and falls deeper into a spiritual trance. Like any sadhu, or Hindu ascetic, he undertakes severe penance to liberate his soul from reincarnation's endless cycle of birth, death and rebirth. Stretched out in the middle of the road, rolling hour after hour, mile after mile through crowds and heavy traffic, he is making his trip to eternal bliss. But this is no ordinary holy roller. He is also on a mission to bring peace to the world. He has rolled thousands of miles in the last 19 years, turning round and round so many millions of times that just pondering the thought can make your head spin. Yet to the 55-year-old sadhu, the constant turning is refreshing. As a sadhu, the Rolling Baba is a wanderer who survives on alms. Apology by Plato. Philosophy bites.

The scientific method is an ongoing process, which usually begins with observations about the natural world. Human beings are naturally inquisitive, so they often come up with questions about things they see or hear and often develop ideas (hypotheses) about why things are the way they are. The best hypotheses lead to predictions that can be tested in various ways, including making further observations about nature. In general, the strongest tests of hypotheses come from carefully controlled and replicated experiments that gather empirical data. Depending on how well the tests match the predictions, the original hypothesis may require refinement, alteration, expansion or even rejection.
Although procedures vary from one field of inquiry to another, identifiable features are frequently shared in common between them. Overview The DNA example below is a synopsis of this method Process Formulation of a question Hypothesis Prediction. Future of an expanding universe. Observations suggest that the expansion of the universe will continue forever.
If so, the Universe will cool as it expands, eventually becoming too cold to sustain life. For this reason, this future scenario is popularly called the Big Freeze. Cosmology Infinite expansion does not determine the spatial curvature of the Universe. YouTube. YouTube. YouTube.
