does anyone know if we are somewhat close or on the road to replicate gravity in space?

Question

prolong exposure to space causes harm due to lack of gravity.

Answer 1

We CAN and HAVE replicated gravity in space. Just take a tilted wheel and make it rotate real fast. The objects inside the wheel will feel like gravity. This is because of centripetal force.

Answer 2

Not even remotely; to replicate gravity, we'd have to understand it first, and physicists can't even agree on what it is. The best we're able to do now is to simulate gravity by rotating all or a portion of a spacegoing vessel, so that the sensation of centrifugal force presses out to the circumference of your rotation. Also, for a REALLY long voyage, I suppose you could make do with a prolonged burn: Constant acceleration would also approximate some force of gravity, if you could find a really powerful fuel that gave you about a million times the "oomph" that conventional rocket fuel does now (to maintain acceleration, you have to continuously thrust, and with our current technology, there's no way to carry enough fuel to do the job, and the relatively short distances we are planning travel in the forseeable future just don't make that kind of burn practical.

Answer 3

The closest we can get to simulating gravity in space is to spin your space station so centripetal acceleration pushes you against the wall. We still haven't a clue how to turn gravity on and off like electric and magnetic fields. But as far as we know, gravity control doesn't violate any fundamental laws. I've got a hunch that we'll solve this problem some time in the next few decades. Why? Because the speed of new discoveries being made is increasing doubly exponentially. We'll make thousands of times as many discoveries this century as we did in the 20th century.

Answer 4

No, we are not even sure how gravity is sent across space(propagated). The exchange particles (that create and transmit gravity) have been postulated and named gravitons.
Einstein's Unified Field Theory was supposed to combine the four major forces in the Universe: Gravity, Electromagnetism, The Strong Nuclear Force, and the Weak Nuclear Force. Every force except for gravity has been traced to one force. Try looking up M-Theory and super-string theory. See my first source for the most recent Gravity Theory.

Answer 5

There is gravity in space, there is gravity everywhere. In some places it is stronger than in others but it is always there as long as there is mass. What do you think is keeping the moon from flying off into space away from earth?

We don't need to understand something to replicate it. We don't understand if light is a particle or a wave put there are experiments to show how it can behave as both.

Answer 6

Wow....someone has been paying attention in science class! I'm so proud of you!

Answer 7

No, Not even close.
