Is time a illusion?
The concept of time is simply an illusion made up of human memories, everything that has ever been and ever will be is happening RIGHT NOW.
Most people do not even consider the concept of time but there is nothing in the laws of physics to state that it should move in the forward direction that we know..
Does time exist in space?
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.
What is the 7th dimension?
In the seventh dimension, you have access to the possible worlds that start with different initial conditions. … The eighth dimension again gives us a plane of such possible universe histories, each of which begins with different initial conditions and branches out infinitely (hence why they are called infinities).
What is the 11th dimension?
The 11th dimension is a characteristic of spacetime that has been proposed as a possible answer to questions that arise in Superstring Theory, which involves the existence of 9 dimensions of space and 1 dimension of time.
Are there 2 dimensional beings?
James Scargill, a physicist at the University of California, has written a paper reporting that the laws of physics allow for the existence of a life-supporting two-dimensional universe. MIT’s Technology Review has reviewed the paper and found that the work does show that such a 2+1 universe could exist.
Can time be separated from space?
In the context of special relativity, time cannot be separated from the three dimensions of space, because the observed rate at which time passes for an object depends on the object’s velocity relative to the observer.
Does the present exist?
One way of seeing this is to recognize that the notion of “present,” as sandwiched between past and future, is simply a useful hoax. After all, if the present is a moment in time without duration, it can’t exist. … When we see something moving in space, we can follow how its position changes in time.
Does the past still exist?
The past and future do not exist and are only concepts used to describe the real, isolated, and changing present. This conventional model presents a number of difficult philosophical problems, and seems difficult to reconcile with currently accepted scientific theories such as the theory of relativity.
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 takes people back in time.
Is time a real thing?
Time is a prime conflict between relativity and quantum mechanics, measured and malleable in relativity while assumed as background (and not an observable) in quantum mechanics. To many physicists, while we experience time as psychologically real, time is not fundamentally real.
Can we go forward in time?
Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.
Can gravity exist without mass?
The only way to get gravity is with mass. The more mass, the more gravity you get. Without mass, you can’t have gravity. … The force of gravity that we feel is actually just an acceleration towards the center of the Earth at 9.8 meters per second squared, or 1G.
How old is the universe?
The age of the universe based on the best fit to Planck 2018 data alone is 13.772±0.040 billion years. This number represents an accurate “direct” measurement of the age of the universe (other methods typically involve Hubble’s law and the age of the oldest stars in globular clusters, etc.).
How many dimensions are there?
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
Is there space without time?
There is no such thing as absolute space or absolute time. Space is not independent of time and vice versa, as Newton had believed. Space and time are linked inseparably in what is called spacetime, per Einstein. All matter in the universe is responsible for the curvature of spacetime.
Can space and time exist without matter?
Right: so can space-time exist without matter? According to our best theory of space-time: yes. Our best theory of space-time is general relativity, and this admits solutions without matter. … There is no space-time without matter, because there is never no matter.
How many dimensions do we live in?
In everyday life, we inhabit a space of three dimensions – a vast ‘cupboard’ with height, width and depth, well known for centuries. Less obviously, we can consider time as an additional, fourth dimension, as Einstein famously revealed.
What if nothing existed?
If nothing did exist, it wouldn’t be nothing, it would be something. There is only something, which is the same as existence, exists, existing, to be, and being. There is no opposite state, and it remains this way, always and forever. Existence was never created, or came from somewhere, or anywhere.
