      • A universe with density greater than the critical density has positive curvature, creating a closed universe that can be imagined like the surface of a sphere. And if the universe’s density is less than the critical density, then the universe is open and has negative curvature, like the surface of a saddle.

  2. Feb 2, 2021 · In one of the most important advances in modern physics, Einstein recognized that when space-time is curved, objects do not follow straight lines. He reckoned that Earth, for example, orbits the...

  3. On a curved surface, the shortest distance between two points is actually a curve, technically known as a geodesic, which we can perhaps visualize when we think, for example, of a plane flying the shortest route between London and New York which, as travelers will know, follows a "great circle" path over Newfoundland rather than what appears to ...

  4. Dec 2, 2019 · Light beams should stay on the straight and narrow over billions of years, so we can use distant probes to "smooth over" tiny little bumps and wiggles like those caused by galaxies and black holes,...

    • Black holes suck. Black holes have a gravitational pull so intense that not even light can escape their clutches. They drain the life out of stars, ripping away layers of gas and shredding the component atoms.
    • Earth is closer to the sun in summer. Most people know that the Earth doesn't travel around the sun in a perfect circle, so it is easy to see why some make the leap and assume that the seasons are caused by the distance to the sun.
    • The sun is burning. Fire needs three things to survive: fuel, heat and oxygen. The sun has fuel as it is composed mainly of hydrogen and helium gas. Helium is an inert element and does not burn like some of its volatile neighbors on the periodic table, but hydrogen is highly flammable.
    • The asteroid belt is very hazardous. There is no doubt that there is a lot of rock in the area of our solar system known as the asteroid belt. Sitting between Mars and Jupiter, this band of fragments contains over 3,000 minor planets and more than 750,000 separate asteroids measuring more than 3,280 feet (1,000 meters) across.

  7. Aug 8, 2014 · Local Curvature of Space. According to Einstein’s theory of general relativity, massive objects warp the spacetime around them, and the effect a warp has on objects is what we call gravity. So, locally, spacetime is curved around every object with mass.
