According to Einstein's theory of relativity, as the speed of a spaceship approaches the speed of light,?

Question

a) metabolism and mass decrease
b) metabolism and mass increase
c) metabolism and mass remain constant
d) aging, relative to earth, would speed up
e) aging, relative to earth, would slow down

Answer 1

E is correct as written.

C is correct, relative to people in the spaceship.

Relative to the earth, metabolism would slow, aging would slow, time would slow, and mass would increase.

Answer 2

You make a statement as to einstein being wrong because of what you believe IF you could prove what you say is correct then einstein would be wrong But every experiment has shown einstein to be correct Just making a statement does not make him wrong, evidence does. The fact that you ask Lola to elaborate cos you dont understand means that you do not have a clue as the WHAT einstein said or proved about the speed of light, or ANY of the experimental evidence that supports the fact that the speed of light is constant "isn't that light technically traveling faster than light according to another galaxies point of view" IT aint traveling faster the light either technically, in your imagination, or any other way

Answer 3

c) metabolism and mass remain constant
e).aging, RELATIVE to earth, would slow down .

These two are correct. d) is not correct as e) is correct.
a),b), are are not correct as c) is correct.

c) is correct becasue

With in the space ship, the physical laws remain the same.

Nothing special can be observed.

We have to consider a) and b) only if C) is wrong

C) Would have been wrong if it was stated that ‘with respect to earth, the metabolism and mass remain constant’.

Answer 4

Mass increases (towards infinity)
Length contracts
Time slows down for the traveller
Nuclear/Atomic reactions slow down
(Metabolism and aging slow down)

Answer 5

I know that E is true. If there are more then one answers then I would have no idea.

The theory says basically, that once you reach the speed of light, time stops, which why in science fiction movies, you need to travel the speed of light in order for time machines to work (back to the future, you needed a lightning bolt to power, etc)

Answer 6

E
metabolism would appear to slow and mass would rise

Answer 7

time slows and mass increases it's e

Answer 8

aging relative 2 earth will slow down... TWIN PARADOX theories..........i hope

Answer 9

I've heard of E being true....not sure about the others.

Answer 10

E - never heard any of the others . . . .that'd be crazy!
