A substance called antimatter is at the heart of one of the greatest mysteries of the universe. We know that every particle has an antimatter companion that is virtually identical to itself but with the opposite charge. When a particle and its antiparticle meet, they annihilate each other — disappearing in a burst of light. ...
Is there gravity in space? Yes, there is! In fact, on the International Space Station (ISS), which orbits Earth at an altitude of around 220 miles (354 km), the force of gravity is still about 90 percent of what it is here on Earth. So how can the International Space Station be called “zero gravity”?
Yes, there is! In fact, on the International Space Station (ISS), which orbits Earth at an altitude of around 220 miles (354 km), the force of gravity is still about 90 percent of what it is here on Earth. So how can the ISS be in “zero gravity”? What is zero gravity? Well, let’s start ...
Have you ever wondered what would happen if the Earth stopped spinning? Well, the speed of the Earth’s rotation is 1,037 mph at the equator, so everything that is not embedded into the bedrock would simply keep moving if the Earth stopped spinning — animals, people, trees, buildings, etc. The oceans would continue to rotate by ...
It appears that gravity affects genes Living at low gravity affects cells at the genetic level, according to a study of worms in space. Genetic analysis of Caenorhabditis elegans worms on the International Space Station showed “subtle changes” in about 1,000 genes. Gravity affects genes in the low gravity conditions of space travel Stronger effects were found in some ...
The vast majority of planets near foreign stars are discovered by astronomers with the help of sophisticated methods. An exoplanet like Beta Pictoris c does not appear in the image, but reveals itself indirectly in the spectrum. A team of scientists from the Max Planck Institutes for Astronomy and Extraterrestrial Physics has now succeeded in ...
A lot of our notions about space are based on the concept of gravity, or more accurately our current understanding of it. Our understanding of gravity until the late 1990s was that gravity attracts things, holds things together, and in a way, stabilizes the universe as a whole. It was in 1998 that scientists stumbled ...
Gravity is one of the fundamental concepts in physics. Gravity is used to explain the creation and sustenance of the universe, from the smallest particle to the biggest of galaxies. In 2009, a physics professor named Erik Verlinde proposed something radical that shook the foundations of physics. He theorized that gravity does not actually exist ...
