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 inside. Would there be a gravity? Answers to those questions find in this video...

It would be hard to find a person who haven't saw on TV how astronauts float inside International Space Station orbiting around Earth. On question why is it so, answer would be "because they are weightless". But why are they weighless? The most common answer is "there is no gravity in space!". We bring you short video in which you can find right answer on this question...

Our world, Earth, is changing before our eyes. Take a look on new HD images of Earth and watch how it changes. Incredible 4k supercomputer images of Earth brought to you on video...

The Standard Model is the collection of theories that describe the smallest experimentally observed particles of matter and the interactions between energy and matter. Three categories of particles form the Standard Model. Matter is composed of quarks and leptons. The fundamental bosons provide three forces: electromagnetism, the strong nuclear force and the weak nuclear force. Gravit

Is levitation possible? Watch this video and make your own conclusion. In a riveting demonstration, Boaz Almog shows how a phenomenon known as quantum locking allows a superconductor disk to float over a magnetic rail -- completely frictionlessly and with zero energy loss. You can see how a super-thin 3-inch disk levitate something 70,000 times its own weight.

Brian Greene is one of the most famous proponent of the superstring theory, the idea that minuscule strands of energy vibrating in a higher dimensional space-time create every particle and force in the universe. In this video Greene is showing how unanswered questions (What caused Big bang?....) have led to new theory that says that our Universe could be just one of many other universes, par

We bring you short video from popular TED Talks project. Murray Gell-Mann brings visibility to a crucial aspect of our existence that we can't actually see: elemental particles. He won the Nobel Prize in Physics for introducing quarks, one of two fundamental ingredients for all matter in the universe. Murray Gell-Mann is been called "the man with five brains" -- and he has the resume to prove

Can we really feel the temperauture? Do our senses have ability to compare absolute temperatures of different bodies? Your probable answer would be "Yes", but think again! This video brings you an explanation of principle on measuring the temperatures...

Quantum computers are future of computers and computing technology. Quantum computers store and process information using quantum mechanical states. Their abilities are far beyond conventional computers. This video by futurist Christopher Barnatt explains what this means and the future implications.

Time is fourth dimension, in which events can be ordered from past through present into the future, and also is the measure of events and intervals between them. Trying to understand time, humans (philoshopers and scientist) have developed two viewpoints. One is that time is something what is part of structure of Universe, and another that time is subjective thing, something what humans us

If someone ever asks you for proves that Earth is round, you can use one or more of those proves:

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

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, 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

Are We Alone is the name of interesting serial on Discovery Channel. It helps us answer many questions from astronomy, astrophysics, cosmology,....

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

There are many ways to prove that our Mother Earth is rounded. One of them is that humans (austornauts) saw it. We bring you beautifull compilation of videos made from International Space Station... Watch this on the largest screen available. This 4k video features some of the most astonishingly beautiful images from the Gateway to Astronaut Photography based at NASA's Johnson Space Center.

This video shows incredible chemical reaction of Mercury(II) thiocyanate while it decomposite. Cause of decomposition is heat.

What is Universe, and how big is it? Is there edge of Universe, or center? The Universe is commonly defined as the totality of existence, including planets, stars, galaxies, the contents of intergalactic space, and all matter and energy.The broadest definition of universe is that it is simply everything, while a narrower definition is that the universe is limited to what can be observed.
