Gravity Explained ByAnupum Pant I’m always amazed by how teachers all around the world come up with fantastic ideas to make science easier for kids. A couple of months back we saw a video of Dan Burns using a trampoline to explain the space-time warping at a Physics Teacher SOS worksho...
A 2,000-kg spacecraft is blasting away from the surface of an unknown planet the same size as the Earth. At 1500km above the surface, an instrument onboard reads the gravitational force to be 18000 N. What is the planet's mass?

astronauts orbiting Earth in a shuttle or space station experience zero gravity because the spacecraft continually accelerates in its orbit in order to prevent it from being pulled into the atmosphere. This acceleration, which is often referred to as a centrifugal force, counterbalances gravity exactl...
What this means is that space and time are connected – if you move really fast through space, time slows down for you compared to someone who is moving slowly. This is why astronauts – who are moving very fast in space –age a tiny bit more slowly than people on Earth. ...
"We need to study dark matter, dark energy and other issues that can't be well explained by Einstein's theory of general relativity alone so far. We hope to discover new physics through gravity research," said Shao, who is actively participating in scientific research projects related to puls...
All of them experienced increases and decreases in the size of different parts of the brain. The researchers said that the longer an astronaut spent in space, the bigger the differences in size were.The research produced some interesting findings. The researchers explained that, “Gravity is not...
Gravity is explained as an entropic force caused by changes in the information associated with the positions of material bodies. A relativistic generalization of the presented arguments directly leads to the Einstein equations. When space is emergent even Newton's law of inertia needs to be ...
Now that we have a little understanding of the composition of light, we can begin to resolve the oft under explained concept of "the speed of light". Since light itself is just a form of electromagnetic radiation, the speed of light is just an easy way of talking about the speed of ele...
was observed to undergo variations in its motion that could not be explained by perturbations from Saturn, Jupiter, and the other planets. Two 19th-century astronomers,John Couch Adamsof Britain andUrbain-Jean-Joseph Le Verrierof France, independently assumed the presence of an unseen eighth planet...
