Ancient seagrass holds secrets of the oldest living organism on Earth
It’s big, it’s old and it lives under the sea — and now an international research collaboration has confirmed that an ancient seagrass holds the secrets of the oldest living organism on Earth.
million and stretches the entire length of the country. The Sun is represented by the Globe arena in Stockholm, the largest spherical building in the world. The planets are placed and sized according to scale with the inner planets being in Stockholm and Jupiter at the International airport Arlanda. The outer planets follow in the same direction with Saturn in Uppsala and Pluto in Delsbo, 300 km from the Globe. The model ends at the Termination shock, 950 km from the Sun.
At each planet station, exhibits provide information about astronomy and the natural sciences, and also about related mythology and culture. The Stockholm Visitor’s Board (former Stockholm Information Service) was a sponsor of the project in the beginning, like several museums, theaters, parks and scientific institutions.
The world’s largest spherical building is 110 m in diameter, the Globe in Stockholm (aka Ericsson Globe) represents the Sun in Sweden Solar System.
This new equation might finally unite the two biggest theories in physics, claims physicist
Linking general relativity and quantum mechanics with wormholes.
One of the most stubborn problems in physics today is the fact that our two best theories to explain the Universe – general relativity and quantum mechanics – function perfectly well on their own, but as soon as you try to combine them, the maths just doesn’t work out.
But a Stanford theoretical physicist has just come up with a new equation that suggests the key to finally connecting the two could be found in bizarre spacetime tunnels called wormholes.
Now you don’t have to fall into a black hole!
As far as we know, there are four fundamental forces that hold our Universe together – gravity, electromagnetism, and the strong and weak nuclear forces.
But, in April last year, physicists in Hungary saw evidence of a possible fifth force of nature, one that could potentially explain some of the lingering mysteries in our Universe, such as dark matter.
From the Planck scale to the cosmic scale, the size comparison of the universe will show you just how large our universe is! This is an update to my previous size comparison video published on the same date in 2015.

There are many improvements over the 2015 version, which include animated lens flares, one complete zoom from helium to the observable universe with no pictures cut out, descriptions for every picture, better star models, more accurate scaling, removed omniverse due to lack of scientific sources and much more!
THE “POTSDAM GRAVITY POTATO” SHOWS VARIATIONS IN EARTH’S GRAVITY
People tend to think of gravity here on Earth as a uniform and consistent thing. Stand anywhere on the globe, at any time of year, and you’ll feel the same downward pull of a single G. But in fact, Earth’s gravitational field is subject to variations that occur over time. This is due to a combination of factors, such as the uneven distributions of mass in the oceans, continents, and deep interior, as well as climate-related variables like the water balance of continents, and the melting or growing of glaciers.
CARLO ROVELLI remembers the first time he glimpsed the beauty of Einstein’s theory of general relativity. He was an undergraduate lounging on a beach in southern Italy, leafing through a rodent-nibbled textbook. “Every so often I would raise my eyes from the book and look at the glittering sea: it seemed to me that I was actually seeing the curvature of space and time.”
