Where is the outer limit of solar system?

The outer limit of our Solar System is a bit tricky to define, as it is constantly expanding and changing. Generally, however, most astronomers agree that the outer limit of our Solar System can be found at the Oort Cloud.

This is an extensive shell of small, icy bodies like comets and asteroids, which exists at a radius of between 5,000 and 100,000 astronomical units from the Sun. The outermost contents of the Oort Cloud are still gravitationally bound to our Solar System, but by the time you reach this outer limit, the Sun’s influence is pretty negligible.

Beyond this, there is still a lot of undiscovered territory, which is thought to include stellar black holes, rogue planets, and other remnants of star formation.

Will humans ever leave the Milky Way?

At the present moment, there is no technology that would allow humans to leave the Milky Way galaxy. However, it is possible that in the future, advances in technology could make this a reality. The distances between galaxies are enormous, and even light, which is the fastest thing in the universe, takes tens of thousands of years to cross the space between them.

In order to explore galaxies, humans would need to develop faster-than-light travel, which is something that is not yet possible.

Assuming that faster-than-light travel is one day possible, humans would be able to venture out from our galaxy and explore the universe beyond it. We could potentially even set up colonies in other galaxies, a feat that would require a great deal of research and preparation.

For now, however, the Milky Way will remain our home, and as long as humanity exists, it will likely remain so.

What is outside of space?

It is a difficult question to answer because there is no definitive answer. Space is an ever-expanding expanse with no observable boundary. Scientists agree that there is no physical boundary that marks the end of space.

Some theories suggest that the edge of space could be the event horizon of a black hole, where matter has been pulled in and can no longer escape, or that the edge of space is made up of dark matter, an invisible, unidentified force.

While we cannot definitively say what may exist beyond the boundaries of space, we can study and theorize what might be out there. Some scientists theorize that beyond the boundaries of space, there are other dimensions and universes that could be a part of a larger ‘multiverse’.

This means that our universe is not alone and could exist alongside other universes. In addition, some scientists suggest that the galaxies that are at the edge of the observable universe are traveling away from us at a speed faster than the speed of light, meaning we can’t observe them.

Others discuss the possibility of wormholes, which are tunnels connecting two points in space-time, leading to completely new realms beyond our own. Ultimately, we can only hypothesize what is beyond the boundaries of our observable universe, and more research is needed to understand the true extent of our universe.

What is underneath Earth in space?

Directly underneath Earth in space is mostly empty, vacuum filled space. Although, any astronauts, or robotic probes and satellites in lower Earth orbit will be found in this region. The Van Allen radiation belts, which are donut-shaped rings of high-energy radiation caused by energetic particles trapped in Earth’s magnetic field, can also be found in this space.

Beyond this, the next closest body in space is the Moon, which is an average distance of 238,855 miles away from Earth. This region is also home to millions of pieces of man-made space debris, such as defunct satellites and pieces of rocket stages, which orbit the Earth at speeds of up to 17,500 mph.

Did NASA find a new planet?

No, NASA has not found a new planet. While researchers with NASA have discovered a number of new planets in our solar system since 2000, none of these have been Earth-sized planets located in our Sun’s habitable zone.

In October of 2018, NASA’s Transiting Exoplanet Survey Satellite (TESS) was launched to detect new planets outside our solar system. The mission aims to increase the number of known exoplanets, which could potentially include Earth-sized planets in a star’s habitable zone.

Since it was launched, the mission has already discovered a number of exoplanets, and it is predicted that it will find thousands of other planets in the next few years. However, as of August 2020, it is yet to discover an Earth-sized planet in a star’s habitable zone that could potentially be suitable for life.

Will Voyager 1 escape the solar system?

Yes, Voyager 1 will eventually escape the solar system. It is currently speeding away from the Sun at nearly 38,000 miles per hour, farther away than any other spacecraft has ever gone. Voyager 1 is now in what is called the “Heliosheath”, which is the edge of the solar system, and is currently about 11 billion miles from the sun.

At this point, Voyager 1 has left the solar system’s magnetic field, so it’s not actually being pushed any longer. It is moving more freely through interstellar space, beyond the “bubble” of the solar system’s influence.

But the spacecraft still has a long way to go. It will likely take another 300 years before it is far enough away to free itself entirely from the Sun’s gravity. Once that happens, Voyager 1 can truly be said to have left the solar system.

How big is the universe?

The universe is unimaginably big, so much so that it’s almost impossible to comprehend. According to the latest scientific estimates, the universe is approximately 93 billion light years in diameter and contains at least two trillion galaxies.

This means that the total number of stars in the observable universe alone is roughly in the region of one septillion, or 1 with 24 zeros written after it.

In comparison, the size of our own Milky Way galaxy is just 100,000 light-years in diameter and contains an estimated 100-400 billion stars, with a diameter for the observable universe that is about 93 times greater than that of the Milky Way.

The observable universe represents all the galaxies and stars that are visible from Earth using high-powered telescopes, though with current technology it’s impossible to observe anywhere close to the entire universe because of its sheer size.

Scientists estimate that there is a lot more matter and space beyond our observable universe and hypothesize that the edges of the universe could stretch back an innumerable number of light years and the the universe is infinitely large.

Where does space end?

Space is a seemingly never-ending expanse, and there is no definite answer to where it ends. Generally speaking, people refer to the area outside of Earth’s atmosphere as “space”. This includes the area that Earth’s gravity still reaches, stretching about 63,000 miles away from the planet, but also includes further reaches until the area occupied by other planetary objects, such as the Moon, Mars, and other satellites.

Beyond this area is considered the interplanetary and interstellar medium. The exact boundaries of space are still being debated among scientists, with some suggesting it may not have any boundaries.

From the perspective of humanity, space is thought to end where the Sun’s magnetic field and cosmic rays become too weak to interact with Earth’s atmosphere. This is theorized to be at the outer edge of the Oort cloud, beyond which lies the interstellar medium, composed of vast amounts of gas, dust, and radiation.

How far does space go?

The answer to this question is that there is no definite answer because the universe is an ever-expanding and ultimately unknowable entity. That said, what we do know is that space is believed to extend at least 93 billion light-years in all directions, based on the observations made by NASA’s Wilkinson Microwave Anisotropy Probe (WMAP).

WMAP measured variations in the cosmic microwave background radiation, which allowed astronomers to calculate the size and age of the universe. Beyond this, however, the universe may stretch out indefinitely in all directions.

In fact, many scientists believe that the universe is actually infinite and may contain an infinite number of galaxies, stars, and other cosmic objects.

Does the universe have an ending?

The answer to this question is not simple and depends on the theory of the universe you subscribe to. In the Big Bang Theory, which states that the universe is constantly expanding and cooling, the universe does not have an ending.

It will eventually reach an equilibrium point where the universe is in a state of maximum entropy, and at that point, the end of the universe cannot be defined.

However, if the universe is finite and bound, then it may have a finite lifespan and an ending point. This is why some theorists have proposed the Big Bounce model, which suggests that the universe goes through cycles of expansion and contraction and that the end of the universe will lead to a new cycle of expansion.

Ultimately, the answer to this question is still open to debate, and we may never know for certain if the universe has an ending or not.

Who created the God?

It is impossible to answer this question fully, for there is no definite answer. Different cultures and religions have different ideas about the origin of gods, so it ultimately depends on which religion or theology you accept as valid.

According to most religions, god or gods have always existed and have no definite origin. In polytheistic traditions, multiple gods or goddesses usually fought against each other or had family relations to explain their origin.

In monotheistic religions such as Christianity and Judaism, god is usually considered to be an omnipresent being who has no origin.

Why is space infinite?

The universe is a vast and mysterious thing, and the concept of infinity is even harder to fully understand or explain. It’s generally accepted, however, that space is not finite and is, in fact, infinite.

This means that, no matter how far we travel and explore, our journey will never end and will never actually reach a physical boundary.

One of them is the “Big Bang” theory, which states that the universe originated from a single point – an infinitely small, dense and hot singularity that subsequently exploded and expanded outward. This theory suggests that space has grown continuously since its origin and that it continues to expand outward.

Other theories propose that space is curved, rather than straight, and that its geometry prevents it from ever reaching a finite endpoint. If the universe is curved, no matter how far we travel, we can never reach that end point.

We can only come around to where we started.

Still other theories suggest that while one part of the universe may expand, other parts may contract, providing somewhat of a balancing system in which the universe as a whole remains stable and infinite.

Regardless of which theory we choose to believe, the fact is that space is likely infinite, and any answers suggested are more theories than facts. It’s impossible to know for certain why space is infinite, and so the mystery remains.

Does space have a bottom?

No, space does not have a bottom. Space is an infinite void that goes on forever with no physical boundaries. Even though some space-related concepts like gravity, dark matter and dark energy help to explain the behavior of matter in the universe, they do not create a bottom or surface to space.

Instead, they affect how matter behaves on the grand scale of space-time.

The concept of a “bottom” of space also defies logic, as space itself is not a physical thing and therefore cannot have a physical boundary or bottom. If anything, the outer reaches of our observable universe could act as a kind of “edge” to space.

Beyond this edge, the universe would be impossible to observe and likely undetectable, though that does not mean the universe doesn’t extend far beyond what we can see.

Will the universe go dark forever?

The answer to this question is not certain, as scientists have not yet concluded definitively whether or not the universe will simply end in a “big crunch” at some point, or if it will continue expanding for eternity.

The current prevailing theory states that the universe is expanding at an accelerating rate, and that eventually all of the matter will become too far apart from each other for stars to form or for light to exist.

This is referred to as the “heat death” of the universe.

Therefore, the universe will not “go dark,” but all of the light sources may slowly fade away, until all that is left is a vast and empty void. So, it is possible that the universe will become dark and cold, but this is still a matter of speculation.
