Who created universe?

God did not create the universe, the man who is arguably Britain’s most famous living scientist says in a forthcoming book. In the new work, The Grand Design, Professor Stephen Hawking argues that the Big Bang, rather than occurring following the intervention of a divine being, was inevitable due to the law of gravity.

How does universe look like?

The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m). Assuming that space is roughly flat (in the sense of being a Euclidean space), this size corresponds to a comoving volume of about 1.22×104 Gpc3 (4.22×105 Gly3 or 3.57×1080 m3).

Why anything exists at all?

The questions pertaining to “why there is anything at all?”, or, “why there is something rather than nothing” has been raised or commented on by philosophers including Gottfried Wilhelm Leibniz, Ludwig Wittgenstein, and Martin Heidegger – who called it “the fundamental question of metaphysics”.

What caused the universe to exist?

Most physicists now think that the universe began with the Big Bang. At first all the matter and energy in the universe was crammed together in one unimaginably small dot, and this exploded. This follows from the discovery, in the early 20th century, that the universe is expanding.

Is time a dimension?

“Time is ‘separated’ from space in a sense that time is not a fourth dimension of space. Instead, time as a numerical order of change exists in a 3D space. Our model on space and time is founded on measurement and corresponds better to physical reality.”

Is 4th Dimension possible?

Mathematically, we can describe the 4th dimension but we may never experience it in the physical realm. Even so, that hasn’t stopped us from looking for evidence of higher dimensions. One model which helps us conceive of it easier and understand it better is a tesseract or hypercube. This is a cube within a cube.

How long will the universe live?

200 billion years

Can Time Machine be invented?

Recent investigations into this question have provided some evidence that the answer is no, but it has not yet been proven to be impossible.” Even the slight possibility of time travel exerts such fascination that many physicists continue to study not only whether it may be possible but also how one might do it.

What existed before the universe?

The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.

What’s the purpose of universe?

The universe is simply the collection of galaxies, stars, planets, comets, meteorites, and other solar system detritus, plus whatever dark matter and dark energy turn out to be. The universe is governed by laws of nature that themselves have no purpose other than dictating what matter and energy do.

How large is space?

Today we are fairly confident that the Milky Way is probably between 100,000 and 150,000 light years across. The observable Universe is, of course, much larger. According to current thinking it is about 93 billion light years in diameter.
