What is outside our 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.

How many dimensions exist?

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.

What was there before the universe?

In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that’s what we’ve been told by physicists for the past several decades.

Which universe are we living in?

The Sun is one among hundreds of billions of stars in the Milky Way galaxy, and most of those stars have their own planets, known as exoplanets. The Milky Way is but one of billions of galaxies in the observable universe — all of them, including our own, are thought to have supermassive black holes at their centers.

We live in a world of three dimensions.

We move through space , either left or right, forward or backward, up or down. Everything around us, from the houses we live in to the objects we use in everyday life, has three dimensions: height, length, and width.

Do different timelines exist?

Multiple timelines is not a reality yet (as of 2016’s science and technology), but exists only in Marvel/DC universe. It is something that is used to explain the paradox of time-travel.

Can the universe be reborn?

A UNIVERSAL CYCLE of birth and rebirth occurs every trillion years or so, according to one new cosmology. Big bangs result when two 10-dimensional “branes” collide (1) and expand (2) and then collide again (4). In this scenario, our universe (3) marks just one phase in this infinite cycle.

Is it possible to cross into another universe?

Even if the universe is infinite, we may never know because we’ll likely never be able to travel an infinite distance in finite time. We could attempt to travel just far enough that we run into alternate versions of ourselves, but that may be just as impossibe. First of all, the universe is constantly getting bigger.

Did two universes collide?

In the multiverse hypothesis, our universe could have popped into existence near another universe. When it expanded, it ran into the neighboring universe; the resulting collision would have left a mark (like a bruise) on our universe.

What is beyond the universe called?

Outside the bounds of our universe may lie a “super” universe. Space outside space that extends infinitely into what our little bubble of a universe may expand into forever. Lying hundreds of billions of light years from us could be other island universes much like our own.

Will I exist again if time is infinite?

It is impossible to destroy and create matter. Thus, everything that has existed still exists, and everything that will exist already exists, just not in the state(s) it did or is going to. And even if time is infinite you would not be born again.

What was Earth before life?

At its beginning, Earth was unrecognizable from its modern form. At first, it was extremely hot, to the point that the planet likely consisted almost entirely of molten magma. Over the course of a few hundred million years, the planet began to cool and oceans of liquid water formed.

How did matter come from nothing?

In the quantum realm, something really can emerge from nothing. In theory, the Schwinger effect states that in the presence of strong enough electric fields, (charged) particles and their antiparticle counterparts will be ripped from the quantum vacuum, empty space itself, to become real.
