Quick Answer: Will Humans Ever Travel To Other Galaxies?

What does space smell like?

sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’.

Some astronauts have likened the smells of space to walnuts..

Can we ever reach Andromeda?

Currently there is no possibility but there might be a possibility in the future, Andromeda is about 2.53 million light years away from us and even if we somehow even travel at the speed of light, it would take 2.53 million years to get there.

Will we ever be able to travel faster than light?

The fact is we’ll never be able to travel beyond the speed of light, at least based on our current understanding of established physics. … The LHC, the largest and highest-energy particle accelerator we have, boosts protons as close to the speed of light as we can get, but they never quite hit the mark.

How fast could humans travel in space?

about 16,150mphOut into space Once at a steady cruising speed of about 16,150mph (26,000kph) in orbit, astronauts no more feel their speed than do passengers on a commercial airplane.

What is outside the universe?

Encountering the Unknown Despite its strangeness, this first idea is one of the easiest to digest. Astronomers think space outside of the observable universe might be an infinite expanse of what we see in the cosmos around us, distributed pretty much the same as it is in the observable universe.

Can we see Andromeda galaxy from India?

Yes, you can see a few other galaxies without using a telescope! … The nearby Andromeda Galaxy, also called M31, is bright enough to be seen by the naked eye on dark, moonless nights. The Andromeda Galaxy is the only other (besides the Milky Way) spiral galaxy we can see with the naked eye.

What galaxy do we live in?

The Milky WayWe live in one of the arms of a large spiral galaxy called the Milky Way.

What is faster than the speed of light?

Photons, by their very nature, cannot exceed the speed of light, but particles of light are not the only massless entity in the universe. Empty space contains no material substance and therefore, by definition, has no mass. … “Therefore, empty space can certainly expand faster than light.”

Would a body decay in space?

If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.

What is the hottest thing in the universe?

A CERN experiment at the Large Hadron Collider created the highest recorded temperature ever when it reached 9.9 trillion degrees Fahrenheit. The experiment was meant to make a primordial goop called a quark–gluon plasma behave like a frictionless fluid. That’s more than 366,000 times hotter than the center of the Sun.

What are the 4 types of galaxy?

In 1936, Hubble debuted a way to classify galaxies, grouping them into four main types: spiral galaxies, lenticular galaxies, elliptical galaxies, and irregular galaxies. More than two-thirds of all observed galaxies are spiral galaxies.

Does space ever end?

It’s because of the shape of space. Our part of space, or the observable universe, has a special shape: it is flat. That means if you and a friend each had your own rocket ship and you both took off and travelled in a straight line, forever and forever, you would never meet.

Could we ever leave the Galaxy?

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.

How long would it take to travel to another galaxy?

To get to the closest galaxy to ours, the Canis Major Dwarf, at Voyager’s speed, it would take approximately 749,000,000 years to travel the distance of 25,000 light years! If we could travel at the speed of light, it would still take 25,000 years!

How cold is empty space?

Gas between stars, as well as the solar wind, both seem to be what we call “empty space,” yet they can be more than a thousand degrees, even millions of degrees. However, there’s also what’s known as the cosmic background temperature, which is minus 455 degrees Fahrenheit.

Is there anything between galaxies?

The space between stars is known as interstellar space, and so the space between galaxies is called intergalactic space. … Intergalactic space is as close as you can get to an absolute vacuum. There’s very little dust and debris, and scientists have calculated that there’s probably only one hydrogen atom per cubic meter.

Can a star exist outside a galaxy?

No, not all stars are in a galaxy. They may have once belonged to a galaxy, but they are not a part of it any more. Some of these so-called “stellar outcasts” or “intergalactic stars” have actually been observed by NASA’s Hubble Space Telescope. … In other words, they are truly “intergalactic”, or between galaxies.

Can you see the Milky Way with your eyes?

The milky way galaxy is one out of at least 100 billion in the universe. … Our galaxy stretches 100,000 light years wide. Every star you can see with the unaided eye is located within the milky way. The only object you can see (without optical aid) in the sky outside of the milky way is the Andromeda Galaxy.
