will it ever be possible to travel to another galaxy

will it ever be possible to travel to another galaxy插图

We have not even traveled to another planet in Solar system..Man have only reached Moon the satellite of earth.With present technology it isimpossible.to go to another galaxy. Explanation: Our milky way galaxy alone stretch about 100,000 light years..Nearest Galaxy Andromeda. is about 2.5 million light years away.

How long does it take to travel to another galaxy?

This shortens the time needed to travel to another galaxy with respect to the traveler. This phenomenon gives hope to the scientists that intergalactic travel is possible for humans. A common example that is quoted in this regard is that Andromeda Galaxy is 2 million light years away but it would take just 28 years for the astronaut.

Is it possible to travel to a neighboring galaxy?

Since that moment, an idea has circulated the scientific world which is to travel to a neighboring galaxy. The name given to that phenomenon is ‘Intergalactic Travel’. Such a journey is limited to the hypothesis, speculation and, science fiction at least for now due to several reasons. The first and the most obvious one is the ‘Distance’.

Is intergalactic travel possible for humans?

This phenomenon gives hope to the scientists that intergalactic travel is possible for humans. A common example that is quoted in this regard is that Andromeda Galaxy is 2 million light years away but it would take just 28 years for the astronaut. However, the requirements of fuel become unrealistic for such a journey.

Do we need to travel to other universes?

Now, if you believe a quantum physics-dominated notion of parallel universes, then there’s no need to travel to other universes, because you are already inhabiting multiple alternate universes (though not necessarily all of them). Can’t decide which dress to wear? No matter-you’ve worn them both, in two separate parallel universes.

How does time dilation work?

When an object moves at the speed of light, Time Dilation takes place. This shortens the time needed to travel to another galaxy with respect to the traveler. This phenomenon gives hope to the scientists that intergalactic travel is possible for humans. A common example that is quoted in this regard is that Andromeda Galaxy is 2 million light years away but it would take just 28 years for the astronaut. However, the requirements of fuel become unrealistic for such a journey.

What was Freeman Dyson’s spacecraft called?

This is exactly what was proposed by Freeman Dyson as his team made a spacecraft called ‘Orion’ . It had the capacity to carry thousands of nuclear bombs and Dyson said that detonating them one after another will provide the necessary thrust to the craft. This inter-stars journey could prove to be the first step towards a travel to another galaxy.

Why are astronomers spreading to all parts of the universe?

Astronomers are spreading to all parts of the space these days. Efforts are being made to support longer missions so that manned spacecraft could be sent to the far-off destinations. For example, different satellites are orbiting around planets like Neptune but no man has ever gone that far in the space. Science did discover that there are hundreds and thousands of other galaxies in the universe other than the Milky Way.

How far is the Milky Way from the closest galaxies?

The estimated distance between Milky Way and the closest galaxies is hundreds of thousands to millions of light years. This vast separation makes it an impossible journey for humans, at least with the technology we have these days.

How much fuel does an intergalactic travel take?

The amount of acceleration needed will require 4,100,000 kg of fuel per kg of payload. The weight of fuel adds to the payload hence alternate means of collecting fuel on the way will have to be arranged. Even if all this is managed somehow, an intergalactic travel is expected to happen in the next century.

How fast can an object move at 10% of the speed of light?

However, things are not that simple. The fastest object that the humans know moved at a speed of 38,610 miles per hour. One-tenth of the speed of light means that we will need to develop a spacecraft that can move at 18,628 miles per second.

Why does the speed of travel have to match the speed of light?

The speed of journey will have to match the speed of light if we want to complete it in reasonable amounts of time because regular flight will take millions of years. Another factor that will need quite a lot of working is the durability of the spaceship. The temperatures of space can fluctuate spontaneously and it can have disastrous effects on …

Why are FTL travels so troublesome?

Possible mechanisms for FTL travel are troublesome due to violations of causality according to our current understanding of physics. How about travelling through some kind of wormhole or suchlike? The theoretical models for wormholes which have been constructed so far tend to collapse when there’s some whiff of the possibility of information travelling faster than light.

Why would time travel to Andromeda be shorter?

Though a trip to the Andromeda galaxy would be limited by the speed of light, the time experienced by the traveller would be shorter due to the time dilation effects of special relativity.

How many light years away is the Milky Way?

Our milky way galaxy alone stretch about 100,000 light years..Nearest Galaxy Andromeda. is about 2.5 million light years away.#N#Eevn if we travel at speed of light it will take 2.5 million years to reach there.Maximum man made probes traveled is about 23 kilometers/second.Speed of light is 300,000 kilometers per second.

How Might Extra-Terrestrial Life Elsewhere in the Universe Be Different?

If humans were to populate another planet with a completely different environment, our bodies would surely need to adapt through evolution. To understand this, let’s consider what extra-terrestrial life forms might be like. How would they be different if they were to exist?

What degree does Glenn Stok have?

Glenn Stok has a Master of Science degree and applies his research to educate his readers with information on science and philosophy. For many years scientists have been studying the endurance of humans for long periods in space. This article is about the requirements for human survival to achieve distant intergalactic travel.

What is the first step to a Mars mission?

First Step: Inhabit Mars. Our present robotic missions have found that there are resources on Mars to sustain human life, such as water beneath the surface. There are also other raw material resources necessary to construct the communities of the future on Mars without the need to send these raw materials from Earth.

Why do scientists think big?

Scientists think big. They imagine the impossible only to work hard at trying to solve a dilemma that stands in the way of achieving those goals. If nothing else, it’s enjoyable to entertain the thoughts of someday going to a distant planet in another solar system, or maybe even farther out to another galaxy.

What would happen if a newborn was born without gravity?

The delivery of a newborn would be entirely different without gravity. The amniotic fluids would just float out and become airborne. These fluids would need to be contained, probably similar to how the toilet works in the international space station, with suction .

Why does the inner ear develop before birth?

For example, our inner ear develops before birth to achieve a sense of balance. The normal tendency to move and kick while in the womb will change due to weightlessness. The side effects on humans are not known. The delivery of a newborn would be entirely different without gravity.

How many lenses do bees have?

Bees have hundreds of lenses in each eye.

How far away are other galaxies than the Milky Way?

Galaxies other than our Milky Way and is smaller satellite galaxies are millions of light years away. Given that nothing can travel faster than light any such journey would take millions of years.

Which two theories are incompatible?

Also, our theories of relativity and quantum mechanics each explain and predict things with high accuracy. The two theories however are incompatible with each other. We know that new physics is required to unify these theories and to explain black holes.

Is it possible to travel to another galaxy?

New physics may provide a way of travelling millions of light years in a reasonable time. So, with our current understanding travelling to another galaxy is not feasible. Time will tell.

How does the Starshot project work?

In the simplest outline of this project, a giant laser on the order of 100 gigawatts shoots at an Earth-orbiting spacecraft. That spacecraft has a large solar sail that is incredibly reflective. The laser bounces off of that sail, giving momentum to the spacecraft. The thing is, a 100-gigawatt laser only has the force of a heavy backpack. You didn’t read that incorrectly. If we were to shoot this laser at the spacecraft for about 10 minutes, in order to reach one-tenth the speed of light, the spacecraft can weigh no more than a gram.

How fast are interstellar probes going?

So, great; we have interstellar space probes currently in operation. Except the problem is that they’re going nowhere really fast. Each one of these intrepid interstellar explorers is traveling at tens of thousands of miles per hour, which sounds pretty fast. They’re not headed in the direction of any particular star, because their missions were designed to explore planets inside the solar system. But if any of these spacecraft were headed to our nearest neighbor, Proxima Centauri, just barely 4 light-years away, they would reach it in about 80,000 years.

How fast can a probe go?

To make interstellar spaceflight more reasonable, a probe has to go really fast. On the order of at least one-tenth the speed of light. At that speed, spacecraft could reach Proxima Centauri in a handful of decades, and send back pictures a few years later, well within a human lifetime.

How long would it take to reach Proxima Centauri?

But if any of these spacecraft were headed to our nearest neighbor, Proxima Centauri, just barely 4 light-years away, they would reach it in about 80,000 years.

How powerful is a spaceship laser?

This is where the rubber meets the interstellar road when it comes to making spacecraft travel the required speeds. The laser itself, at 100 gigawatts, is more powerful than any laser we’ve ever designed by many orders of magnitude.

Where are laser beams visible?

A representation of laser beams is visible emanating from the corners of the craft’s lightsail. (Image credit: Planetary Habitability Laboratory, University of Puerto Rico at Arecibo) Paul M. Sutter is an astrophysicist at The Ohio State University, host of Ask a Spaceman and Space Radio, and author of "Your Place in the Universe.".

What is the force of a 100 gigawatt laser?

The laser bounces off of that sail, giving momentum to the spacecraft. The thing is, a 100-gigawatt laser only has the force of a heavy backpack . You didn’t read that incorrectly.

Are Your Carbon Copies Out There?

One very prominent mind twister in both science fiction and real-life science is the concept of parallel universes. This is hardly surprising, since the idea of multiple copies of yourself existing at the same time is both existentially disturbing and thrilling.

What does Neil deGrasse Tyson say about the universe?

Neil deGrasse Tyson, on the other hand, says that if you come from a universe with higher dimensions, then it could be as easy to move between dimensions as stepping from one room to another. And in string theory —one of the leading contenders in bridging the seemingly insuperable gulf sundering quantum mechanics and general relativity—the assumption is that we actually have far more dimensions in this universe than we previously thought and that we just fail to detect them because they are actually very small, curled up in the infinitely minute, trans-subatomic realms beyond the reach of our instruments.

Who is the physicist who believes that parallel universes exist?

That depends. The American theoretical physicist and string theorist extraordinaire Brian Greene , of Columbia University, argues that the plausibility of multiversal travel—conceding that parallel universes really do exist—hinges on which multiverse concept you subscribe to.

Is the multiverse a scientific theory?

The idea of a multiverse is not considered a scientific theory but rather, as Ethan Siegel of Forbes puts it, “a theoretical consequence of the laws of physics as they’re best understood today.” The idea that space-time begins and stretches infinitely implies that existence is mathematically bound to repeat itself at some point—a notion sometimes called the “quilted multiverse.”

Can we travel between universes?

No matter—you’ve worn them both, in two separate parallel universes. Meanwhile, theoretical physicist Michio Kaku believes that our universe will end up in a “ big freeze ,” and that technology can one day allow us to travel between universes.

Can we prove that there is an alternate universe?

But how can we prove (or disprove) any of these arguments without gaining first-hand experience of it? Much as many aspects of our universe still remain elusive to us, it’s currently impossible to acquire any proof to confirm which of these hypotheses is right. But while we don’t have the means to definitively prove whether alternate universes do exist, and whether we could traverse borders to move from one to another, it’s highly unlikely that a topic as stimulating as this will disappear anytime soon, either in science fiction or in real-life science.

Why won’t humans migrate to a planet outside the solar system?

Humans will never migrate to a planet outside of Earth’s solar system because it would take far too long to get there, Swiss Nobel laureate Michel Mayor said Wednesday. Mayor and his colleague Didier Queloz were on Tuesday awarded …

How many exoplanets have been found in our galaxy?

Since then over 4,000 exoplanets have been found in our home galaxy.

When did Mayor and Queloz discover the planet?

Using custom-made instruments at their observatory in southern France, Mayor and Queloz in October 1995 discovered what had previously only existed in the realm of science fiction—a planet outside Earth’s solar system.

Who said it was up to the next generation to answer the question of whether there is life on other planets?

Mayor said it was up to the "next generation" to answer the question of whether there is life on other planets.
