If someone ever asks you for proves that Earth is round, you can use one or more of those proves:
What if the Earth were hollow?
Why are astronauts weightless in Space?

What if the Earth were hollow?
Imagine that we dig a tunnel going from one side of our planet to the other side. What would happen with the body falling through that tunnel? Or what if the Earth were shell, with empty space insid...

Watch Now !Gravity explained - from Newton to Einstein
One of four fundamental forces of nature is gravity. It's weakest force of all and always is attractive. Gravtiation force is proportional to body masses and inversly proportional to the square distance between them. From a cosmological perspective, gravitation causes dispersed matter to coalesce, and coalesced matter to remain intact, thus accounting for the existence of planets, stars, galaxie
Ring Nebula explained
The RIng Nebula (Messier 57) is one of the most known objects on sky. It is a planetary nebula in the northern constellation of Lyra.
The NASA/ESA Hubble Space Telescope and Hubblecast bring you a new and detailed look at the famous Ring Nebula. The Ring's distinctive shape makes it a popular illustration for astronomy books. But new observations of the glowing gas shroud around an old,
Hubble Space Telescope
Hubble, iconic telescope that opened our eyes for miracles of Universe. Responsible for unlocking many mysteries of the final frontier, the most renowned telescope in the world is in danger of being lost forever. The Hubble Space Telescope has explored the creation of stars and planets, the glory of supernovas and the formation of super massive black holes, charted dark matter and changed foreve

Roundest object on Earth
Do you know what is the roundest object in the world? It's a PERFECT sphere made of silicone, and it will be used to redefine a base unit of mass - one kilogram. In this video you can see a story about this roundest object and story about unit of mass...
A kilogram isn't what it used to be. Literally. The original name for it was the 'grave', proposed in 1793 but it fell victim to the French R
