Biggest problem with space travel is that there is no gravity. Here's what will happen. . . .
1/ Bones become much weaker
2/ muscles become smaller
3/ Overall health declines greatly
That's why you sometimes see astronauts having trouble walking after being in space for so long.

Human beings have a very hard time retaining muscle and bone mass because of the low gravity in space. The body just gets rid of it. Also, the lack of exercise creates digestive and urinary tract problems.

The human body is an extraordinary but, also, anastonishingly complex machine. Like other living organisms, the human body has evolved by adapting to Earth's gravitavional field, and the biological structure and mechanisms of the body have devoped to suit normal Earth gravity.

you may no longer commute on the fee of light. it is not an engineering or technologies challenge. commute at c violates the conventional concepts of physics. Regardless, it quite is bodily achieveable to commute at just about c relative to different bodies. At such speeds, there is definitely no longer something diverse occurring than at relax. it quite is the completed factor of Relativity: that anybody traveling at consistent velocity can justifiably evaluate himself at relax. velocity itself does definitely no longer something on your physique, to the spaceship, nor do something by any ability to alter the end results of any test interior of it from the outcomes you may locate at relax relative to different bodies. You journey time and age via precisely the quantity it quite is examine out on your watch, which operates precisely the way it does everywhere else. you may ought to shelter the spaceship fairly lots however, for the astonishing energies with which the atoms of diffuse hydrogen gas and visual easy blueshifted into the perplexing gamma ray could be hitting it could tear it aside.

Bone mass decreases.

Virtually none.
Unless we can travel at speed of light or just below.
