How long would it take to get to another universe at the speed of light?

How long would it take to get to another universe at the speed of light?

“So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world. From the perspective of a traveler moving at the speed of light, it would appear to take no time at all.”

How long would it take to cross our galaxy at the speed of light?

“Even if you could travel at the speed of light (300,000 kilometers, or 186,000 miles, per second), it would take you about 25,000 years to reach the middle of the Milky Way. If we could travel outside our galaxy and look back, this is what our Milky Way Galaxy might look like from above.”

How many years would it take to travel across the 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 many light years would it take to cross the universe?

“Size: 94 Billion Light Years. The most distant objects in the Universe are 47 billion light years away, making the size of the observable Universe 94 billion light years across.”

How many years is 1 light-year?

“Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.”

Is anything faster than the speed of light?

“Nothing in the universe can go faster than the speed of light. As it happens, it was an illusion, a study published in the journal Nature explained earlier this month.”

How many years is 500 light years?

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

Can humans reach half the speed of light?

“Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. According to Albert Einstein’s theory of special relativity, summarized by the famous equation E=mc2, the speed of light (c) is something like a cosmic speed limit that cannot be surpassed.”

How fast Milky Way is moving?

“And how fast is the Milky Way Galaxy moving? The speed turns out to be an astounding 1.3 million miles per hour (2.1 million km/hr)! We are moving roughly in the direction on the sky that is defined by the constellations of Leo and Virgo.”

Why can we see 46 billion light-years away?

“The light that travels the longest gets stretched by the greatest amount, and the object that emitted that light is now at a greater distance because the universe is expanding. We can see objects up to 46.1 billion light-years away precisely because of the expanding universe.”

What is 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.”

Will we ever reach 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.”

Why can’t we see 15 billion light years away?

“Galaxies may exist at that distance, but their light would be too faint for our telescopes to see. C. Because looking 15 billion light-years away means looking to a time before the universe existed.”

Can a human travel a light-year?

“Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.”

How many light years is infinite?

“This future visibility limit is calculated at a comoving distance of 19 billion parsecs (62 billion light-years), assuming the universe will keep expanding forever, which implies the number of galaxies that we can ever theoretically observe in the infinite future (leaving aside the issue that some may be impossible to …”

How many years is 1,000 light-years?

“To do so, you will need a speed of almost the speed of light, so in the reference frame of Earth, you will have spent just a tad more that 1000 yr to travel 1000 ly. i.e. 1000 years, 4 hours, and 23 minutes in Earth’s reference frame.”

Do you age in light-years?

“Re: How would you age at the speed of light The simple answer is, anything moving through space at c, equal to the speed of light in a vacuum, experiences zero time flow. If you were to travel at the speed of light, you would experience no time.”

How many light-years is the Milky Way?

“Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across.”

How long would it take to reach Andromeda at the speed of light?

“Although it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years to get there if (and it’s a huge ‘if’) we could travel at the speed of light.”

Will it ever be possible to travel near the speed of light?

“Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. According to Albert Einstein’s theory of special relativity, summarized by the famous equation E=mc2, the speed of light (c) is something like a cosmic speed limit that cannot be surpassed.”

How long would it take to get to Pluto at the speed of light?

“Other Galaxies”

The Moon	1 1/3 sec
The Sun	8 minutes
Jupiter	35 to 52 minutes
Pluto	5 1/2 hours (on average)
