Quick Answer: What Is On The Other Side Of The Expanding Universe?

At what speed is the universe expanding?

82.4 kilometers per second per megaparsecIt puts the rate of expansion at 82.4 kilometers per second per megaparsec, higher than previous calculations—though it does admit to a 10 percent margin of error, meaning it could as low as 74 or as high as 90..

Does the universe have a shape?

Shape of the observable universe The observable universe can be thought of as a sphere that extends outwards from any observation point for 46.5 billion light years, going farther back in time and more redshifted the more distant away one looks.

What was before the universe?

The initial singularity is a gravitational singularity predicted by general relativity to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.

What’s inside a black hole?

The event horizon is where the escape speed exceeds the speed of light: you’d have to be going faster than light (which is impossible for any bit of matter) to escape the black hole’s gravity. Inside the event horizon is where physics goes crazy. … A singularity is what all the matter in a black hole gets crushed into.

What is beyond the universe for it to expand into?

The universe is everything, so it isn’t expanding into anything. It’s just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there’s no center they’re expanding from and no outer edge to expand into anything else.

What are the boundaries of the universe?

The universe (observable or otherwise) has no boundary in the physical sense. This is one of the most commonly seen misunderstandings about physical cosmology. The universe is not a bubble expanding into a preexisting volume. The universe exists everywhere and and is approximately the same everywhere.

What is beyond the known universe?

Beyond our observable Universe lies the unobservable Universe, which ought to look just like the part we can see. The way we know that is through observations of the cosmic microwave background and the large-scale structure of the Universe.

Will our universe end?

Theories about the end of the universe. The fate of the universe is determined by its density. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the “Big Freeze” scenario below.

Does the universe expand in all directions?

The Big Bang should not be visualised as an ordinary explosion. The universe is not expanding out from a centre into space; rather, the whole universe is expanding and it is doing so equally at all places, as far as we can tell.

How many dimensions are there?

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.

Can we see Edge of Universe?

As far as we can tell, there is no edge to the universe. Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe. This conclusion is reached by logically combining two observations.

Is the space infinite?

Newsletter. First, it’s still possible the universe is finite. … The observable universe is still huge, but it has limits. That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago.

How fast is the universe expanding in mph?

Credit: ESA/Hubble & NASA, RELICS; Acknowledgement: D. Coe et al.) Already mindbogglingly large, the universe is actually getting bigger all the time. Some of the nearest galaxies to ours are receding at a rate surpassing 240,000 kilometers per hour (150,000 miles per hour).

What is at the end of space?

No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.

What’s the biggest thing in the universe?

The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure. For perspective, the universe is only 13.8 billion years old.
