Time is the presence of motion and forces and it is caused by the expansion of space. The perception of time is an emergent phenomenon that is why it is perceived in so many different ways. Present is our perception of the process of time as it records into our memory while past is a record and future does not exist.
Einstein's general theory of relativity established time as a physical thing: it is part of space-time, the gravitational field produced by massive objects. The presence of mass warps space-time, with the result that time passes more slowly close to a massive body such as Earth.
Gravity does NOT warp the flow of time. It's the other way around the warping of time causes gravity.
The measurement of time began with the invention of sundials in ancient Egypt some time prior to 1500 B.C. However, the time the Egyptians measured was not the same as the time today's clocks measure. For the Egyptians, and indeed for a further three millennia, the basic unit of time was the period of daylight.
According to Einstein's general theory of relativity, space and time are tied together, and space-time can bend and curve. "The way to think about it is that that curvature is stretching out time," she says. As time stretches, it slows.
The definition of time is actually highly contested. The most agreed-upon scientific definition is that time is the progression of events from the past to the future. It is integral to the way humans perceive the world. Time moves only in one direction and does not move backward.
Time is a complex and multifaceted aspect of human experience that is shaped by a wide range of factors, including individual perception, physical environment, and cultural context.
The neural clock operates by organizing the flow of our experiences into an orderly sequence of events. This activity gives rise to the brain's clock for subjective time. Experience, and the succession of events within experience, are thus the substance of which subjective time is generated and measured by the brain.
Energy flows in waves, which are cycles. These cycles are the repetitions that create our sense of time.
As a universe, a vast collection of animate and inanimate objects, time is infinite. Even if there was a beginning, and there might be a big bang end, it won't really be an end. The energy left behind will become something else; the end will be a beginning.
That depends on how fast you're traveling. Thanks to Einstein, we know that the faster you go, the slower time passes--so a very fast spaceship is a time machine to the future. Five years on a ship traveling at 99 percent the speed of light (2.5 years out and 2.5 years back) corresponds to roughly 36 years on Earth.
Time dilation occurs when an individual is affected by space travel. Time moves more slowly in space than it does on the earth. This is a result of gravity and relative velocity. Relative velocity is the speed at which one is moving in relation to another object.
Although there is nothing in physics that says time must flow in a certain direction, scientists generally agree that time is a very real property of the Universe. Our science is thus based on the assumption that the laws of physics, and the passage of time, exist throughout the Universe.
Yes, time – or our modern conception of it – was invented.
The universe will get smaller and smaller, galaxies will collide with each other, and all the matter in the universe will be scrunched up together. When the universe will once again be squeezed into an infinitely small space, time will end.
Time seems to follow a universal, ticktock rhythm. But it doesn't. In the Special Theory of Relativity, Einstein determined that time is relative—in other words, the rate at which time passes depends on your frame of reference.
Special & General Relativity Questions and Answers
Time is a dimension, not a force. It is not a force in the same way that mass, by itself, or temperature by itself is not a force.
There's no time without space
Additionally, according to Einstein's general theory of relativity, the gravity of a large object can impact how quickly time passes.
Among physicists, there is no real doubt that time does really, truly exist. It's a measurable, observable phenomenon. Physicists are just divided a bit on what causes this existence, and what it means to say that it exists.
Albert Einstein famously expressed this point when he wrote to a friend, “The past, present and future are only illusions, even if stubborn ones.” Einstein's startling conclusion stems directly from his special theory of relativity, which denies any absolute, universal significance to the present moment.
Albert Einstein once wrote: People like us who believe in physics know that the distinction between past, present and future is only a stubbornly persistent illusion. Time, in other words, he said, is an illusion. Many physicists since have shared this view, that true reality is timeless.
Time is a social construct that we build to plan and schedule our lives. Thus, we are bound to the constructs of the culture we are in. We must embrace the cultures thoroughly to understand who they are in their time and space.
In zero seconds, light travels zero meters. If time were stopped zero seconds would be passing, and thus the speed of light would be zero. In order for you to stop time, you would have to be traveling infinitely fast.
Answer and Explanation: Time is a natural phenomenon because it cannot be stopped, and it is a never stopping process. Time can give an idea regarding the completion of any activity or anything, but it cannot be created.
Because space isn't curved they will never meet or drift away from each other. A flat universe could be infinite: imagine a 2D piece of paper that stretches out forever. But it could also be finite: imagine taking a piece of paper, making a cylinder and joining the ends to make a torus (doughnut) shape.
