Our Galaxy, the Milky Way, is a disk of stars about 100,000 light-years across, and about 1,000 light-years thick. So, to leave our Galaxy, we would have to travel about 500 light-years vertically, or about 25,000 light-years away from the galactic centre.Our Galaxy, the Milky Way, is a disk of stars about 100,000 light-years across, and about 1,000 light-years thick.

Will we ever travel to another galaxy?
The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
Will our galaxy be destroyed?
Our research suggests the Milky Way and Andromeda will begin to interact strongly about 2 billion years from now. The merger will conclude in about 5 billion years.
Has anyone ever left the Milky Way?
On November 5, 2018, Voyager 2 officially left the solar system as it crossed the heliopause, the boundary that marks the end of the heliosphere and the beginning of interstellar space.
Will the universe end?
Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Slowly, stars will fizzle out, turning night skies black.
Can we ever travel faster than light?
Physicists’ current understanding of spacetime comes from Albert Einstein’s theory of General Relativity. General Relativity states that space and time are fused and that nothing can travel faster than the speed of light.
Will the Milky Way collide with Andromeda?
Previous simulations have suggested that Andromeda and the Milky Way are scheduled for a head-on collision in about 4 billion to 5 billion years. But the new study estimates that the two star groups will swoop closely past each other about 4.3 billion years from now and then fully merge about 6 billion years later.
Is the Milky Way falling apart?
Milky Way is being slowly ‘pulled apart’ by the gravity of a neighbouring galaxy – causing it to twist and deform with ‘extreme violence’ The Milky Way Galaxy is being gradually twisted and deformed by the gravitational force of satellite galaxy the Large Magellanic Cloud (LMC), astronomers claim.
How old is our galaxy?
Most galaxies are between 10 billion and 13.6 billion years old. Our universe is about 13.8 billion years old, so most galaxies formed when the universe was quite young! Astronomers believe that our own Milky Way galaxy is approximately 13.6 billion years old.
Where is Voyager 2 now?
The spacecraft is now in its extended mission of studying interstellar space; as of September 16, 2021, Voyager 2 has been operating for 44 years and 29 days, reaching a distance of 127.75 AU (19.111 billion km; 11.875 billion mi) from Earth.
Has Voyager 1 left the Milky Way?
In August 2012, Voyager 1 became the first spacecraft to cross into interstellar space. However, if we define our solar system as the Sun and everything that primarily orbits the Sun, Voyager 1 will remain within the confines of the solar system until it emerges from the Oort cloud in another 14,000 to 28,000 years.
What is outside the universe?
The universe, being all there is, is infinitely big and has no edge, so there’s no outside to even talk about. The current width of the observable universe is about 90 billion light-years. And presumably, beyond that boundary, there’s a bunch of other random stars and galaxies.
What happens when you reach the end of space?
It will expand forever; the galaxies within groups and clusters will merge together to form a giant super-galaxy; the individual super-galaxies will accelerate away from one another; the stars will all die or get sucked into supermassive black holes; and then the stellar corpses will get ejected while the black holes May 6, 2020.
Who created the universe?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
What galaxy do we live in?
We live in one of the arms of a large spiral galaxy called the Milky Way. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre. 100 000 years to cross from one side to the other.
What is the fastest thing in the universe?
In modern physics, light is regarded as the fastest thing in the universe, and its velocity in empty space as a fundamental constant of nature.
Is a black hole faster-than-light?
Supermassive black hole bigger than 7 billion Suns is spinning so fast that it’s close to breaking the laws of physics. Messier 87, star of the first image of the black hole , is spinning between 2.4 to 6.3 times faster than the speed of light .
Is hyperspace possible?
While hyperspace is not a current form of space travel, there is ongoing research to determine how viable it is — and what the experience would be like. In 2013, a group of physics students corrected the view of what happens when spaceships fly at the speed of light.
How fast is the Milky Way moving towards Andromeda?
And that’s going to happen someday! The Andromeda galaxy is currently racing toward our Milky Way at a speed of about 70 miles (110 km) per second. Ultimately, the two galaxies will collide and merge.
What is the next galaxy after Andromeda?
Andromeda is the closest big galaxy to the Milky Way and is expected to collide with the Milky Way around 4.5 billion years from now. The two will eventually merge into a single new galaxy called Milkdromeda.
What is the largest galaxy in the universe?
Largest galaxy: IC 1101 Our Milky Way galaxy is around 100,000 light-years across, but that’s fairly average for a spiral galaxy. In comparison, the largest known galaxy, called IC 1101, is 50 times larger and about 2,000 times more massive than our galactic home.
