How long would it take to get to the edge of our galaxy?

How long would it take to get to the edge of our galaxy?

The disk of our home galaxy – the Milky Way – is bigger than we previously thought. A new study shows it would take 200,000 years for a spaceship traveling at the speed of light to go across the entire galaxy.

How long would it take to get to the edge of our universe?

The edge of the observable universe is about 270,000,000,000,000,000,000,000 miles away. If you drive at a steady 65 miles per hour, it will take you 480,000,000,000,000,000 — that’s 4.8 × 10¹⁷ — years to get there, or 35 million times the current age of the universe.

How long would it take to reach the end of the Milky Way?

The disk of our home galaxy – the Milky Way – is bigger than we previously thought. A new study shows it would take 200,000 years for a spaceship traveling at the speed of light to go across the entire galaxy.

Can we see the edge of our galaxy?

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 there end to 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.

How far into space have we gone?

The probe launched on Sept. 5, 1977 — about two weeks after its twin Voyager 2 — and as of August 2022 is approximately 14.6 billion miles (23.5 billion kilometers) away from our planet, making it Earth’s farthest spacecraft.

What’s beyond the universe?

The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.

Is the space infinite?

There’s a limit to how much of the universe we can see. The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).

How many universes are there?

In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.

Will humans ever leave the solar system?

“It’s very unlikely,” Matteo Ceriotti, an aerospace engineer and space systems engineering lecturer at the University of Glasgow in the U.K., told Live Science in an email. However, as Ceriotti explained, “unlikely” does not mean it’s “impossible,” and suggested a way it could theoretically be done.

How far is the closest black hole?

This illustration provided by NOIRLab in November 2022 depicts the closest black hole to Earth and its sun-like companion star. Astronomers have discovered the closest known black hole to Earth, just 1,600 light-years away. Scientists reported Friday that this black hole is 10 times more massive than our sun.

Will the Milky Way eventually collapse?

Our Milky Way is on a collision course with another spiral galaxy called Andromeda. Today Andromeda is visible as a speck of light in the night sky, but about 5 billion years from now, it will be tangled up with us. Our galaxy’s spiral arms will disappear, and so will our supermassive black hole.

How cold is space?

Space is very, very cold. The baseline temperature of outer space is 2.7 kelvins (opens in new tab) — minus 454.81 degrees Fahrenheit, or minus 270.45 degrees Celsius — meaning it is barely above absolute zero, the point at which molecular motion stops.

What did NASA discover at the edge of the universe?

Although there must be many very distant galaxies and quasars that we are not yet able to detect, astronomers have observed radiation from an even more remote source, literally at the edge of the observable universe.

What was there before the universe?

In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that’s what we’ve been told by physicists for the past several decades.

How long would it take to get to the farthest galaxy?

At the rate of 17.3 km/sec (the rate Voyager is traveling away from the Sun), it would take around 225,000,000,000,000 years to reach this distance. At the speed of light, it would take 13 billion years!

Could we ever travel to the edge of the universe?

Unfortunately, since universe is technically expanding faster than the speed of light (due to the expansion of space between matter), it is theoretically impossible to ever reach the “edge” of the universe, since it will always be moving away faster than we could ever move towards it!

How many years is 500 light years?

It would take 500 years to travel 500 light-year distance at the speed of light.

How long would it take to colonize our galaxy?

Even with very conservative limits placed on the speed of the space craft, a majority of the galaxy could be colonized in less than a billion years – a fraction of its total age.
