Is it possible to create a time machine?

Is it possible to create a time machine?

To create a time machine would require negative energy, and quantum mechanics appears to allow only extremely small regions of negative energy. And the forces needed to create an ordinary-sized region with time loops appear to be extremely large.

Will it ever be possible to travel back in time?

There are known to be solutions to the equations of general relativity that describe spacetimes which contain closed timelike curves, such as Gödel spacetime, but the physical plausibility of these solutions is uncertain. Many in the scientific community believe that backward time travel is highly unlikely.

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.

What’s 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.

Can we go in future?

Traveling into the Future While it’s not possible (yet) to travel to the future fast than the rate at which we’re doing it now, it is possible to speed up the passage of time. But, it only happens in small increments of time. And, it has only happened (so far) to very few people who have traveled off Earth’s surface.

How can I time travel?

Is our future already written?

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.”

How far in the past are we living?

La Jolla, CA – If you think you’re living in the past, you’re right – and science can tell you just how far behind the times you are. According to a new Salk study, it’s at least 80 milliseconds, just slightly longer than the blink of an eye.

Can one live in the past?

While some people live in the past because they don’t want to deal with the present, others live in the past for fear of what may come in the future. Just like watching that favorite old sitcom you’ve seen 100 times, looking back on your life doesn’t bring any surprises.

Who is the creator of this universe?

Born from a lotus emerging from the navel of Vishnu, Brahma creates all the forms in the universe, but not the primordial universe itself.

What is 100% of the universe made of?

The universe is composed almost completely of dark energy, dark matter, and ordinary matter. Other contents are electromagnetic radiation (estimated to constitute from 0.005% to close to 0.01% of the total mass-energy of the universe) and antimatter.

How will the universe end?

Eventually, the entire contents of the universe will be crushed together into an impossibly tiny space – a singularity, like a reverse Big Bang. Different scientists give different estimates of when this contraction phase might begin. It could be billions of years away yet.

What will happen in 2050?

World population is expected to increase from 7 billion today to over 9 billion in 2050. A growing population is likely to increase pressures on the natural resources that supply energy and food. World GDP is projected to almost quadruple by 2050, despite the recent recession.

How our life will be in 2050?

By 2050, about 75% of the world population will be living in cities. Then there will be buildings touching the sky and cities will be settled from the ground up. Roads will be built up to several floors. And to move around, the buildings will be connected to the skywalk.

How will we travel in 2040?

The rise of high-speed rail. By 2040, cross-border train journeys will be smoother and improved in many parts of the world. Computer networks and the Internet of Things (IoT) will manage national and international rail networks, allowing trains to run faster and closer together.

Can the past be erased?

Memory erasure has been shown to be possible in some experimental conditions; some of the techniques currently being investigated are: drug-induced amnesia, selective memory suppression, destruction of neurons, interruption of memory, reconsolidation, and the disruption of specific molecular mechanisms.

Can we see the past on earth?

No. Because you cannot reach the speed of light, even if you had started travelling away from Earth the day you were born, you could never catch the light carrying the image of your being born.

Why am I still living in the past?

Reasons you live in the past may include traumatic experiences, fear that it will happen again, or shame that it ever did. You may also wish to change an outcome, hang on to the fear of the present or future, or worry that you will never experience a deep emotion, like love, again.

Is the universe infinite in the past?

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). The observable universe is centred on us.
