Is a space elevator possible?

A space elevator is possible with today’s technology, researchers say (we just need to dangle it off the moon) Space elevators would dramatically reduce the cost of reaching space but have never been technologically feasible.

Will a space elevator ever be built?

While progress has been made in several respects, the concept still hovers on the edge of possibility. For some scientists and engineers, the enduring challenges are enough to conclude that a Space Elevator will never be built (at least here on Earth).

Why space elevator is not possible?

An Earth-based space elevator could not feasibly be simply a tall tower supported from below, due to the immense weight – instead it would consist of a cable with one end attached to the surface near the equator and the other end attached to a counterweight in space beyond geostationary orbit (35,786 km altitude).

Is NASA making a space elevator?

Well, it’s not. It is a real possibility — a “space elevator” — that researchers are considering today as a far-out space transportation system for the next century. David Smitherman of NASA/Marshall’s Advanced Projects Office has compiled plans for such an elevator that could turn science fiction into reality.

Is Japan making space elevator?

The Science Council of Japan is proposing a “hybrid space elevator” approach, which means simultaneously developing a concept that would be built from the ground and one to be constructed in space.

What happens if a space elevator falls?

If the break occurred at higher altitude, up to about 25,000 kilometres (16,000 mi), the lower portion of the elevator would descend to Earth and drape itself along the equator east of the anchor point, while the now unbalanced upper portion would rise to a higher orbit.

Would a space elevator work on the moon?

A very long cable



(The cable of a lunar space elevator couldn’t be anchored to Earth’s surface because the relative motions of the moon and our planet wouldn’t permit it.)

How fast would a space elevator be?

Current status

Can you go up and down in space?

In space, there is no “up” or “down.” That can mess with the human brain and affect the way people move and think in space. An investigation on the International Space Station seeks to understand how the brain changes in space and ways to deal with those changes.

Does space have a bottom?

Space has no floor.



However, it’s not really an endless pit, either, because gravity doesn’t pull in one direction. It pulls toward objects that have mass.

Does space have a smell?

A succession of astronauts have described the smell as ‘… a rather pleasant metallic sensation … [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’.

Is there a ceiling in space?

It’s all relative. Inside the International Space Station, the ceiling might as well be the floor. The walls might as well be the ceilings. It’s enough to make your head spin.

Can you go in any direction in space?

There is an up and down in space. “Down” is simply the direction gravity is pulling you, and “up” is just the opposite direction. Since there is gravity everywhere in space, there is also an up and down everywhere in space.

Does space have a end?

Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.

Is there a floor in space?

Space has no floor. However, it’s not really an endless pit, either, because gravity doesn’t pull in one direction. It pulls toward objects that have mass.

How cold is space?

Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).

Is everything in space falling?

All gravitational orbits are actually cases of falling and missing. Astronauts on the International Space Station are not in a no-gravity environment. They are surrounded by the earth’s and the sun’s immense gravity. More correctly, the astronauts are in a state of free fall.

How flat is space?

As far as cosmologists can tell, space is almost perfectly flat.

Is time Travelling possible?

In Summary: Yes, time travel is indeed a real thing. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.

What dimension are we living in now?

What is the 4th Dimension and how does it look like? The world we live in is called the Three Dimensional World or more commonly known as the 3-D World. What is meant by this is that our world(the world we can see and observe) is made up 3 things: Length, Breadth and Height.

Are there multiple universes?

There is not one universe—there is a multiverse. In Scientific American articles and books such as Brian Greene’s The Hidden Reality, leading scientists have spoken of a super-Copernican revolution.

Can a wormhole exist?

Einstein’s theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.

Are there infinite planets?

In fact, scientists today believe it’s very likely there are infinite versions of our planet and ourselves out there somewhere.

How do you enter a parallel universe?

Video quote: Keep moving away from each other as the space fabric between them is being stretched. Well this is happening other universes pop up into existence.

How many dimensions are there?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.

Is there another universe in a black hole?

It is, in fact, and some physicists say they could be one and the same: The singularity in every black hole might give birth to a baby universe. There’s no reason to think our universe is any different.
