10 times Einstein got it right! From Universal speed limit to blackhole; know them all

Explore Einstein's theories through captivating photos: universal speed limit, lensing effects, black holes, gravitational waves, and space-time predictions. Know how he predicted scientific phenomena that we are now starting to prove.

1. Universal Speed LimitEinstein's theory states that all light must obey the speed limit of 300,000 kilometers per second. This was confirmed in 2009 when NASA's Fermi Gamma-ray Space Telescope detected two photons, carrying vastly different energy, traveling at the same speed. These photons originated from a high-energy region near the collision of two neutron stars about 7 billion years ago. (NASA/Robert Gendler)

2. Strong Lensing:Massive objects like galaxies can distort light from distant objects behind them, acting as lenses. This phenomenon, known as strong lensing, was first observed in 1979 when scientists saw a double image of a quasar caused by a galaxy acting as a lens. The warped space due to gravity alters the appearance of the distant object, leading to multiple images (Pexels)

3. Weak Lensing: Similar to strong lensing, weak lensing occurs when a massive object bends light from a farther object, but with no special alignment. This results in the projection of only one image of the distant object, making it appear larger and stretched due to the closer object's gravity. (Pixabay)

4. Microlensing: Stars can also act as lenses, magnifying light from background stars. When a star with planets orbits in the foreground, the light from the background star experiences a temporary increase in brightness. This technique, called microlensing, is used to find exoplanets. NASA's Spitzer Space Telescope discovered an "iceball" planet using microlensing. (Pixabay)

5. Black Hole: Black holes, predicted by Einstein's theory of general relativity, are extremely dense objects with gravity so intense that nothing, not even light, can escape them. In 2019, the Event Horizon Telescope captured the first image of a black hole's event horizon, the point of no return. Other telescopes also observed this black hole to study its properties.

6. Relativistic Jet: The galaxy Messier 87 (M87) contains a supermassive black hole at its center, surrounded by a disk of hot gas and two jets of material shooting in opposite directions. One of these jets points almost directly towards Earth, causing enhanced brightness due to "relativistic beaming." The exact workings of these jets remain mysterious.  (NASA)

7. A Gravitational Vortex: The intense gravity of black holes causes infalling material to "wobble" around them, similar to a spoon stirring honey. In 2016, scientists observed this wobbling matter for the first time using XMM-Newton and NASA's Nuclear Spectroscopic Telescope Array. These observations confirm Einstein's ideas about gravity.

8. Gravitational Waves: First hypothesized by Einstein, gravitational waves were detected in 2016 by the Laser Interferometer Gravitational-Wave Observatory (LIGO). These ripples in space-time traveled for 1.3 billion years before being observed, providing groundbreaking evidence for general relativity. (Pixabay)
