What is the space-time continuum for dummies?
Einstein's theory of special relativity created a fundamental link between space and time. The universe can be viewed as having three space dimensions — up/down, left/right, forward/backward — and one time dimension. This 4-dimensional space is referred to as the space-time continuum.
Can you break the space/time continuum?
It's quite hard to break it when it doesn't really work in the way that science-fiction teaches us. It's not really a “fabric” that can be ripped or torn, though it does get stretched and warped by objects of different masses. The more mass an object has, the more it bends spacetime, which is what creates gravity.
What is space-time theory?
Space-time, in physical science, single concept that recognizes the union of space and time, first proposed by the mathematician Hermann Minkowski in 1908 as a way to reformulate Albert Einstein's special theory of relativity (1905).
What is space-time interval?
in the theory of relativity, a quantity that characterizes the relation between the spatial distance and the time interval that separate two events. From the mathematical standpoint it is the “distance” between two events in four-dimensional space-time.
Can a wormhole be created?
To create a wormhole on Earth, we'd first need a black hole. This is problematic: creating a black hole just a centimetre across would require crushing a mass roughly equal to that of the Earth down to this tiny size. Plus, in the 1960s theorists showed that wormholes would be incredibly unstable.
Can we bend light?
Yes, light can bend around corners. In fact, light always bends around corners to some extent. This is a basic property of light and all other waves. ... The ability of light to bend around corners is also known as "diffraction".
Can gravity bend light?
Gravity bends light Light travels through spacetime, which can be warped and curved—so light should dip and curve in the presence of massive objects. This effect is known as gravitational lensing GLOSSARY gravitational lensingThe bending of light caused by gravity .
Can a magnet bend light?
So there is no way that a magnetic field can bend light. ... For instance, if the object is very small (small compared to the wavelength of the light), the light will simply diffract around the object and be invisible or nearly so anyway.
Does light bend space time?
Light has energy, energy is equivalent to mass, and mass exerts gravitational force. Thus, light creates gravity, i.e. the bending of space-time.
Is gravity faster than the speed of light?
As long as gravitational waves and photons have no rest mass, the laws of physics dictate that they must move at exactly the same speed: the speed of light, which must equal the speed of gravity. ... The speed of gravity is exactly the speed of light, and physics wouldn't have allowed it to be any other way.
Why does light turn into heat?
The infrared energy coming from the sun is not enough to keep Earth as warm as it is. Energy from visible light and ultraviolet light has to play its part, too. ... When visible light is absorbed by an object, the object converts the short wavelength light into long wavelength heat. This causes the object to get warmer.
Does E mc2 apply to humans?
Many people think mass can be converted into energy and vice versa. But E=mc^2 is the equation for mass-energy equivalence. ... Their mass is proportional to the amount of energy they contain. So the human body cannot be converted into energy, because it already is energy!
Why is speed of light c squared?
But why is the speed of light squared? The reason is that kinetic energy, or the energy of motion, is proportional to mass. When you accelerate an object, the kinetic energy increases to the tune of the speed squared.
What does C stand for in E mc2?
Speed of light
Is E mc2 true?
It's taken more than a century, but Einstein's celebrated formula e=mc2 has finally been corroborated, thanks to a heroic computational effort by French, German and Hungarian physicists. ... In other words, energy and mass are equivalent, as Einstein proposed in his Special Theory of Relativity in 1905.
