Why do birds collide with aircraft?
In the language of pilots strike — not the best shot that you can make in bowling. As a rule, this word in aviation, represent the collision of birds with aircraft (with the addition of the word bird (bird) — going to ...
The artificial gravity ceases to be fiction
Artificial gravity has long been described in science fiction novels and shown in movies like "Space Odyssey 2001". Theoretically, the possibility of creating artificial not denied. However, before the projects could be tested in ...
In the new experiment, NASA astronauts will have two months to lie still on the bed
Space travel in zero gravity have on the human body destructive influence. Due to earth gravity people Willy-nilly to keep their body and their muscles are constantly trained. In zero gravity, the muscles all relaxed and quickly a...
As the low gravity of the moon affects the health of astronauts?
the European space Agency ESA is preparing a new generation of astronauts for the next manned space missions to the moon. Recently, they began to teach the use of being dressed in heavy space suits restrict movement. But what abou...
Scientists have rejected the idea of travelling through wormholes
Employee RUDN and his Brazilian colleagues have questioned the concept of using stable wormholes as portals to different points of space-time. The results of their research were published in Physical Review D. the Wormhole is a pr...
Antigravity possible? Science promises to figure it out very soon
One of the most amazing facts in science is how the universal laws of nature. Each particle is subject to the same rules and experiences the same force exists in the same fundamental constants, regardless of where and when. From t...
gravity is an incredibly weak force. Just think about it: you can tear your foot off the ground, despite the mass of the Earth that attracts her. Why is she so weak? Unknown. And may need a very large scientific experiment to find...
Gravitational waves have not shown the presence of extra dimensions
Although last year's discovery of gravitational waves last year, born of the collision of neutron stars, it was awesome, it added extra dimensions to our understanding of the Universe — literally, anyway. the Astronomers at the U...
Physicists have performed the most accurate measurement of the force of gravity
the Force of gravity may seem strong if you on foot is falling a bowling ball, but in reality it is the weakest of the fundamental interactions. Compare it with electromagnetism: attraction across the Earth's gravity will not prev...
Incredible luck allowed us to get a photo while the most distant stars
Due to the effect of gravitational lensing space telescope "Hubble" was able to get pictures of the stars, distant from us 9 billion light years, which at the moment is a record of observations of a single object located far from ...
Other person: how a year-long mission on the ISS influenced American astronaut
In 2016, the American astronaut Scott Kelly returned to Earth after a 340-day stay aboard the International space station (ISS). Such extended space travel became a part of the program space Agency NASA to study the effects of lon...
Physicists have found a way to see the "smile" of quantum gravity
In 1935, when quantum mechanics and General theory of relativity was very young, not very well known Soviet physicist Matvei Bronstein, aged 28 years, made the first detailed study on the harmonization of these two theories in a q...
10 mysteries of space-time, which will be able to solve quantum gravity
the General theory of relativity, in which gravity is born due to the curvature of space-time, wonderful. It was confirmed with an incredible level of precision, in some cases up to fifteen decimal places. One of the most interest...
Why don't we have artificial gravity in space?
Put a man in space, away from the gravitational bondage of the earth's surface, and he will feel weightlessness. Although all mass in the Universe will still affect it gravitationally, they also will attract any spacecraft, in whi...
Gravity can create a strange flash in the quantum world
How to reconcile the two pillars of modern physics: quantum theory and gravity? One or both must yield and surrender. The new approach says that gravity can emerge from random fluctuations at the quantum level, which makes quantum...
NASA astronomers would like to turn the Sun into a giant space telescope
NASA Astronomers try to look further and further into the Universe, and therefore they need large and powerful telescopes. And that is why a team of experts from the jet propulsion Laboratory (JPL) proposed the idea of using the l...
Is there a "zero gravity" at all?
When we see astronauts in space, floating above earth's atmosphere, we say that they experience zero gravity true zero gravity. But they are still the gravitational pull of the Earth, Moon, Sun and every other mass in the Universe...
