I recently listened again to Richard Feynman explaining why the flowing of time is probably an illusion. In modern physics time is just a coordinate, on the same footing as space, and the universe can be described as a four-dimensional object — a spacetime block. In that view, nothing really “flows”.

This idea dates back to the Russians in the early 1970s. The surface of Venus is far too hot, and the atmosphere too dense, for Earth life. However, our air is a lifting gas on Venus with about half the lifting power of helium on Earth. A habitat filled with normal air will float high in the dense Venus atmosphere>
Though table salt, sodium chloride (NaCl), is one of the best-known and most studied chemical compounds known, it still has a few mysteries. Under ambient conditions, it crystallizes in a cubic unit cell and is very stable with one sodium atom (Na) and one chlorine atom (Cl). According to the octet rule, all chemical>

First came GRACE (Gravity Recovery and Climate Experiment) and then we'll have GOCE (Gravity field and steady-state Ocean Circulation Explorer). I'll reveal>
