how big is space?

Question

forget our solar system think about the rest bet your mind goes blank

Answer 1

imagine the biggest space there can ever be and then times it by a million over and over again. in other words its infinite

Answer 2

The Universe was created into a space containment. This containment volume makes up the substance of space which at one time was called aether and now is called dark matter.
The present calculation of the radius of the Universe which both contain the substance of space and the substance of mass,was calculated on the estimated Hubbles's constant.
Its approx 1.42x10^26 meter in radius.However if the space substance is to contain mass structure by contrains the Radius of the Universal containment would be much larger than science gives it credit for.

Answer 3

Estimates are between 15 billion light years and over 100 billion light years and expanding 670 million miles every hour of every day. That's an expansion in radius equal to about the distance from Sun to Saturn. And that amount of increase is just in a single hour.

Answer 4

Everything physics has taught us so far says it is infinite because the universe is always expanding. Even the pictures the hubble took of a dark portion of the sky showed hundreds of new galaxies, and hundreds behind them. Just trying to imagine an edge of the universe could tie your brain in knots. Previous post said there had to be an edge, I disagree since everything in nature and physics is balanced in some way shape or form who is to say the universe dosent just fold in on itself like the symbol of infinity.

Answer 5

After observing many galaxies, Hubble was able to quantify his results. His law of cosmic expansion states that an observer—at any point in the universe—will observe distant galaxies receding from him/her, with radial velocities proportional to their distance from the observer.

An interesting consequence of Hubble's law is that, if one looks out far enough, he/she will perceive the radial velocities of recession as approaching the speed of light. This implies that, for every observer in the universe, there is a unique, spherical horizon of which he/she is the center.

We can calculate the distance to our observational horizon (where c is the speed of light, and H is Hubble's constant):

The horizon is located at distance S = c/H.

S [Horizon] = c/H = (2 x 10^5 km/sec) / (75 km / (sec Mpc)
S [Horizon] = 4,000 Mpc = 1.3 x 10^10 light years = 13B light years

With NASA's Hubble Telescope, we can now see out to almost 10 billion light years. Thus, we can see about 75% of the way out to our own observational horizon. Using the Hubble Telescope, we estimate that there are about 5 x 10^21 stars in the observable universe.

Since objects beyond the horizon would be receding from the observer at speeds greater that that of light, in violation of Special Relativity, there must exist a cosmic "sensor" that prevents the observer from ever seeing beyond his/her particular horizon.

The "sensor" is nothing more or less than the red shift itself. From the observer's point of view, the galatic red shift increases linearly with radial distance. Thus, the farther out an observer tries to look, the redder the universe will appear, until at immense distances it will no longer be visible at all—the light having all been red-shifted into the radio spectrum and beyond. Equivalently, the light frequency of photons from distant galaxies decrease with increasing radial distance, becoming zero at S = c/H (the observable horizon).

Since we do not often allow for negative energy, we must conclude that there exists a natural horizon at S = c/H, beyond which the observer may obtain no further information. But, what about an observer who is stationed right on our horizon? Well, he/she sees a locally normal universe that becomes progressively more and more red-shifted—with vanishing beyond his/her horizon. The new observer can see portions of the universe that we cannot, and we can see portions of the universe that he/she cannot. Such are the consequences of Hubble's law of cosmic expansion coupled with Einstein's Special Theory of Relativity!

Answer 6

Some religion say that we have 7 solar system above and seven below.

But all the same it is very very very big, beyond our imagination.

Answer 7

Theirs no way to tell how much space is in our solar system probably endless.

Answer 8

I don't believe it is infinite, but it is huge. I don't think anything can be infinite, there has to be something on the edges of the universe...

In reality, our universe could only be the size of a gold fish tank in someones house compared to whatever else is out there...

Answer 9

Well theres no sure awnser but most say it is endless most stars we see here on earth are millions of light years away so it is very big.

Answer 10

PaKi_GirL, how can it still be expanding if it is infinite ?

If it is infinite, where is it going to expand to.
It is either infinite or not, or it is expanding or not.
Not both.
