What Does General Relativity Predict? What does general relativity predict? General relativity predicts gravitational waves, as does any theory of gravitation in which changes in the gravitational field propagate at a finite speed. What did general relativity predict? General relativity predicts that the path of light will follow the curvature of spacetime as it passes
Do Distant Stars Have Gravity? Do distant stars have gravity? By looking at slight variations in the brightness of distant stars, scientists say they can determine their surface gravity, a technique that provides important clues to life-hosting properties of the planets that orbit them. Do galaxies have gravity? A galaxy is a huge collection of
Could A Black Hole Destroy The Earth? Could a black hole destroy the earth? Scientists have debunked this perception. Earth is facing no threat because no black hole is close enough to the solar system for our planet. According to NASA, even if a black hole the same mass as the sun replace the sun,
Do Black Holes Follow The Laws Of Thermodynamics? Do black holes follow the laws of thermodynamics? Since a “quantum” black hole emits heat and light, it therefore has a temperature. This means black holes are subject to the laws of thermodynamics. Do black holes obey the second law of thermodynamics? Overview. The second law of
Do Black Holes Break The Laws Of Physics? Do black holes break the laws of physics? Black holes obey all laws of physics, including the laws of gravity. Their remarkable properties are in fact a direct consequence of gravity. In 1687, Isaac Newton showed that all objects in the Universe attract each other through gravity.
Can A Plane Travel Faster Than The Speed Of Light? Asymptotically’ meaning something gets closer and closer to the speed of light, but never quite reaches it. No object can travel faster than the speed of light because as objects travel faster, they get heavier. Therefore, it is only light that can travel at the
Does A True Vacuum Exist? Does a true vacuum exist? Ultimately, a perfect vacuum isn’t possible because quantum theory dictates that energy fluctuations known as ‘virtual particles’ are constantly popping in and out of existence, even in ’empty’ space. What’s a true vacuum? A true vacuum is the stable, lowest-energy state, like sitting still on
Does A Singularity Have Infinite Mass? Does a singularity have infinite mass? Nope. The singularity is a point where volume goes to zero, not where mass goes to infinity . It is a point with zero volume, but which still holds mass, due to the extreme stretching of space by gravity. Does a singularity have
Can Black Holes Travel At The Speed Of Light? No, a black hole can not move at the speed of light in vacuum because (as you stated) it has mass. Nothing that has mass (no matter how slight) can move at the speed of light. How fast do black holes travel? The fast-moving black hole,
How Was There Nothing Before The Big Bang? “There was nothing around before the Big, Big Bang,” Hawking said. His theory is based on the assumption that the universe has no boundaries. … The Big Bang theory holds that the universe in retrospective can shrink to the size of an extremely small “subatomic ball” known
