Can A Spaceship Accelerate In Space? The astronauts on board the International Space Station are accelerating towards the center of the Earth at 8.7 m/s2, but the space station itself also accelerates at that same value of 8.7 m/s2, and so there’s no relative acceleration and no force that you experience. This same principle works
Can Humans Travel A Light-year? So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. … So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft
Can An Electron Move At The Speed Of Light? That means the electron is traveling at 99.9999992% of the speed of light. … That’s less than 1% of the speed of light, but it’s fast enough to get it around the Earth in just over 18 seconds. Read up on what happens when nothing can
Can You Travel Back In Time With Your Mind? Every time we remember something from the past or imagine something that will happen in the future, we engage in mental time travel. Scientists discovered that, whether we mentally travel back into the past or forward into the future, some of the same brain regions are
Can Light Travel In Vacuum Yes Or No? Unlike sound, which needs a medium (like air or water) to travel through, light can travel in the vacuum of space. How does light travel through a vacuum? A vacuum is empty space. There are no molecules of air or anything else in a vacuum. Like all
Is Light Faster In A Vacuum Or Water? Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water. Does light move faster in water? * Light slows down when it passes through other media, such as air or water. … However, light
Why Is Light Faster In Air Than In Water? The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. … Because of the physical differences in the makeup of the materials light actually travels
How Does Time Dilation Affect GPS? How does Gravitational Time Dilation affect GPS? As covered earlier on in the website time runs slower the stronger the gravitational potential you are in. Therefore, from our point of view, the clocks on the satellites will run fast and will no longer be accurate, and this has very
Can A Time Machine Be Made? Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. Can a time machine be built? Travelling in time might sound like a flight of fancy, but some
Can A Time Machine Be Invented? Time travel may soon be possible, according to an astrophysicist who believes he’s worked out a way to build a time machine. Professor Ron Mallett from the University of Connecticut in the US claims to have written a scientific equation that could be used to create a device that
