Which of the following forces may halt the expansion of the universe?

Question

a) Nuclear Forces b) Electrical Forces c) Magnetic Forces d) Gravitational Forces

Answer 1

none of them. the universe will expand for ever. the universe will eventually burn out. unless this dark matter they talk about really exists

Answer 2

Gravitational Forces

Answer 3

d) Gravitational Force

Gravitational Force is the only force that works over vast distance such between galaxies so it is the only force that has the ability to pull all the stars and galaxies together.

By the way, there are is no such thing as an electrical force. There are four force know to man kind and they are strong force, weak force, electromagnetic force and gravity. Strong force and weak force is what makes up nuclear force.

Answer 4

Your final paragraph actually references the Anthropic theory, which says we under no circumstances would've existed in a universe which could no longer help life, subsequently we does not be around to invite a majority of those questions. yet as you suggested, it does make one ask your self no count if there are different many universes available, as a manner to offer sufficient numbers to develop the risk that a minimum of one would be ideal for all times. yet there are different the form to look at this too. life greater to in high quality condition this universe, no longer any different way around. If circumstances were distinctive, in step with probability another form of high quality count would've arisen, that ought to've allowed another style of life. in step with probability our universe is cyclical, with the countless cycles being rather short and subsequently sterile of life. or in step with probability there's a solid reason those ultimately-tuned actual constants have their recent values; our expertise of physics isn't so solid that we can definitively answer that query. in step with probability those values are no longer loose to variety at random reckoning on what universe they are in. Trillions and trillions of years from now, each and all of the stars will finally burn out, or maybe protons themselves would in all probability decay away. Even then, some scientists suspect that there may well be good arrangements of electrons and antielectrons orbiting one yet another, that ought to act fairly like the classic atomic count around us. it might take an unimaginably long term for those debris to end an orbit, and the orbits may well be as huge as a reducing-part galaxy, yet in this long distant destiny, time and area would be sufficient, although rather chilly. in step with probability even then a sparkling form of life ought to strengthen. And if it did, it might probable see our recent era as a procedures too warm and short-lived for all times to strengthen, lots as we view the 1st few seconds after the massive bang. base line, i do no longer think of all of us understand sufficient approximately physics to respond to this question yet. yet it particularly isn't any reason to leap to the tip that it had to be created by using a deity.

Answer 5

Gravitational in a closed or flat universe http://en.wikipedia.org/wiki/Shape_of_the_universe

Answer 6

gravity has a slim chance, but there is just not enough to halt the universe

Answer 7

D In this case its a question of mass and velocity.
