Can there be space without time?
Experiments continue to show that there is no ‘space’ that stands apart from space-time itself…
no arena in which matter, energy and gravity operate which is not affected by matter, energy and gravity..
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.
Is time a man made concept?
Time as we think of it isn’t innate to the natural world; it’s a manmade construct intended to describe, monitor, and control industry and individual production.
Can I travel back in time?
The Short Answer: 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. That kind of time travel sounds like something you’d only see in movies or science fiction books. …
How many dimensions are we living 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.
Is time a real concept?
To many physicists, while we experience time as psychologically real, time is not fundamentally real. At the deepest foundations of nature, time is not a primitive, irreducible element or concept required to construct reality. The idea that time is not real is counterintuitive.
Can a time machine be made?
Travelling in time might sound like a flight of fancy, but some physicists think it might really be possible. BBC Horizon looked at some of the most promising ideas for turning this staple of science fiction into reality. Ron Mallett has a dream: He wants to travel in time.
Is time an illusion?
According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn’t correspond to physical reality. … He posits that reality is just a complex network of events onto which we project sequences of past, present and future.
Are there 10 dimensions?
Superstring theory posits that the universe exists in 10 dimensions at once. Beyond these three visible dimensions, scientists believe that there may be many more. … In fact, the theoretical framework of Superstring Theory posits that the universe exists in ten different dimensions.
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.
Is real life 3D or 4d?
We live in a 3D (D stands for dimensional) world with the 4th dimension as time. By using multiple dimensions in ultrasound, we can find the width, depth and height of an object (in this case, your baby!). Below is short summary of each dimensions and how ultrasound takes advantage of it.
Is time equal to space?
Back in the 1800s, there was space and there was time. … But there was no notion that space and time were in any sense “the same thing”. But then along came Einstein’s Special Theory of Relativity—and people started talking about “spacetime”, in which space and time are somehow facets of the same thing.
Does time exist without motion?
Time can exist without motion. Time is not dependent on motion. It is motion that is dependent on time. But motion (in a clock or sun) does indicate the passage of time.
Why is time the 4th Dimension?
Light clocks A and B moving horizontally through space. According to length contraction, clock A should tick faster than clock B. … But in the 106 years since Einstein, the prevailing view in physics has been that time serves as the fourth dimension of space, an arena represented mathematically as 4D Minkowski spacetime.
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.
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. What does exist is the recent memory of the immediate past and the expectation of the near future.
What are the 26 dimensions?
The 26 dimensions of Closed Unoriented Bosonic String Theory are interpreted as the 26 dimensions of the traceless Jordan algebra J3(O)o of 3×3 Octonionic matrices, with each of the 3 Octonionic dimenisons of J3(O)o having the following physical interpretation: 4-dimensional physical spacetime plus 4-dimensional …
