Question: How Can The Universe Be Flat?

Is Universe flat or round?

All other cosmological data suggests the universe is flat, meaning it has no curvature, similar to a sheet of paper.

These Planck measurements indicate that it could be “closed”, or spherical, which would mean that if you travelled far enough in one direction, you would end up back where you started..

Is a flat universe infinite?

No. We do not know whether the Universe is finite or not. To give you an example, imagine the geometry of the Universe in two dimensions as a plane. … So you have two possibilities for a flat Universe: one infinite, like a plane, and one finite, like a torus, which is also flat.

How many dimensions are in the universe?

10 dimensionsThe 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.

Is there a bottom of the universe?

There is no “bottom” or “top” to the universe.

How do we know the universe is flat?

According to the best measurements astronomers have ever been able to make, the curvature of the universe falls within a range of error bars that indicates it’s flat. Future observations by some super Planck telescope could show a slight curvature, but for now, the best measurements out there say… flat.

Why is the Galaxy flat?

It’s easier to do this in systems with lots of gas and dust, but systems which lack these things find it difficult to lose kinetic energy and thus flatten, because collisions of stars are so rare. So dust-less elliptical galaxies are (roughly) spherical, while dust-full spiral galaxies are flat disks.

Does time have a shape?

Time does not have a shape, time is a numerical expression, used to measure events in various ways. Like the distance between events, and record when an event happened or is going to happen. If you want you could use the numerical expression of time to construct a mathematical model of different shapes.

How thick is the flat universe?

Now fast forward to 81 folds and your paper will be 127,786 light-years, almost as thick as the Andromeda Galaxy. And finally, at 103 folds, you will get outside of the observable Universe, which is estimated at 93 billion light-years in diameters.”

What is outside the universe?

In our own backyard, the Universe is full of stars. But go more than about 100,000 light years away, and you’ve left the Milky Way behind. Beyond that, there’s a sea of galaxies: perhaps two trillion in total contained in our observable Universe.

Why is everything in the universe round?

It uses its gravity to snag bits of space stuff. A planet’s gravity pulls equally from all sides. Gravity pulls from the center to the edges like the spokes of a bicycle wheel. This makes the overall shape of a planet a sphere, which is a three-dimensional circle.

What do they mean when they say the universe is flat?

In a flat universe, Euclidean geometry applies at the very largest scales. This means parallel lines will never meet, and the internal angles of a triangle always add up to exactly 180 degrees—just like you’re used to. But in curved universes, whether finite or infinite, things get weird.

What are the 4 dimensions of the universe?

But we can break this down. Our Universe as we know it has four dimensions: the three dimensions of space (up and down, left and right, back and forth), and one dimension of time that keeps us all ticking along.

How many dimensions do we live 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 the universe flat open or closed?

In such a case, the universe has no bounds, and will expand forever. This is called an open universe. If space has no curvature (i.e, it is flat), there is exactly enough mass to cause the expansion to stop, but only after an infinite amount of time.

Is the universe flat NASA?

Measurements from WMAP The WMAP spacecraft can measure the basic parameters of the Big Bang theory including the geometry of the universe. … We now know (as of 2013) that the universe is flat with only a 0.4% margin of error.

Are there 26 dimensions?

In bosonic string theory, spacetime is 26-dimensional, while in superstring theory it is 10-dimensional, and in M-theory it is 11-dimensional. In order to describe real physical phenomena using string theory, one must therefore imagine scenarios in which these extra dimensions would not be observed in experiments.

What is the 7th dimension?

In the seventh dimension, you have access to the possible worlds that start with different initial conditions. Whereas in the fifth and sixth, the initial conditions were the same and subsequent actions were different, here, everything is different from the very beginning of time.

What are the 12 dimensions?

Awareness of point, line, width, breadth, height, volume, time and spirit. Linear time of space do not bind consciousness here. There is no illusion of separation or limitation. Instead there is a constant experience of the One-ness of God/Goddess/All that is.

What is at the end of universe?

If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.

What is the current age of the universe?

about 13.8 billion yearsThe universe is about 13.8 billion years old, according to new research recently published by an international team of astrophysicists.

Do we live in a flat universe?

The exact shape is still a matter of debate in physical cosmology, but experimental data from various independent sources (WMAP, BOOMERanG, and Planck for example) confirm that the universe is flat with only a 0.4% margin of error.
