The future, though it remains unknown to you, seems to be written already. Einstein himself described it thus: “People like us, who believe in physics, know that the distinction between past, present and future is only a stubbornly persistent illusion.”

Does the future and past 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.
What is the future in physics?
Physics experiments will generate ever more data and analysing that information using artificial intelligence and machine learning will become “the new normal”. I can see environmental concerns having a bigger influence on physics. Scientific lab equipment will become cleaner and greener.
Does the past still exist?
In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.
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. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton’s picture of a universally ticking clock.
What did Einstein say about the future?
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.
Is universe infinite or finite?
The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
Is time finite or infinite?
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.
Is the present an illusion?
“If you think that what is real is the present, you’re wrong. The past and the future are both real. The present is a psychological illusion. The present is just the wall between yesterday and today.
Does time exist all at once?
We can measure that it’s changing around us all over the place – satellites, particle accelerators, anything going fast. And it may be that space and time are the same thing all wrapped up together and it all exists all at once.
Is Future predetermined?
NO , The future isn’t predetermined according to physics.
Can you travel to the past?
The fact that the universe is still around is ample evidence that time travel to the past is impossible.
Can we go 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.
Is it possible to travel back 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 we stop time?
The simple answer is, “Yes, it is possible to stop time. All you need to do is travel at light speed.” The practice is, admittedly, a bit more difficult. Addressing this issue requires a more thorough exposition on Special Relativity, the first of Einstein’s two Relativity Theories.
Is time the 4th dimension?
According to Einstein , you need to describe where you are not only in three-dimensional space — length, width and height — but also in time. Time is the fourth dimension. So to know where you are, you have to know what time it is.
Is our universe an illusion?
A new theory now suggests that the accelerating expansion of the universe is merely an illusion, akin to a mirage in the desert. In 1929, cosmologists discovered that the universe is expanding — that space-time, the fabric of the cosmos, is stretching.
Is past and future an illusion?
But that part of our lives hasn’t yet been written. Except it might’ve. The future might already exist and those three ways we separate time — past, present, and future — are nothing more than an illusion created by our minds. This is the picture of the universe that emerged from Einstein’s theory of relativity.
Why did Einstein say time is an illusion?
As For Einstein… As we saw from Einstein’s quote, he believed that time is an illusion, that both the future and the past are unchangeable, and will play out exactly the way they were meant to.
What was Einstein’s IQ level?
What was Albert Einstein’s IQ? Though some sources estimate theoretical physicist Albert Einstein’s IQ was around 160, there is no indication he ever had his IQ tested, according to biography.com.
Is universe flat or curved?
Most cosmological evidence points to the universe’s density as being just right — the equivalent of around six protons per 1.3 cubic yards — and that it expands in every direction without curving positively or negatively. In other words, the universe is flat.
Who is the creator of this universe?
Brahma is said to be the source of all the knowledge that exists in this world.
When did time begin?
According to the standard big bang model of cosmology, time began together with the universe in a singularity approximately 14 billion years ago.
How many universes are there?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
What is beyond the universe?
The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.
