...to make it closed or open?

Neutrinos are usually thought of as having no mass. However, recently it has been suggested that they may indeed have a very tiny mass. If this is true, because there are so many neutrinos in existence 'flying' about all over the place (millions and millions are passing through your own body all the time - they don't interact very much and so won't hurt you!), their combined mass would be substantial. This mass would then contibute to the mass of the Universe and would tend to close the Universe. It is possible that the neutrino mass could be enough to cause complete closure so we would be living in a spherical universe, and may even provide enough mass to cause the Universe to collapse in the very distant future causing a Big Crunch - the opposite of the Big Bang when the Universe was created.

Isn't this a bit of a confused question? Have you thought-out what you want to know?
First, don't you mean 'neutrinos'? And why ever should they affect 'Universe gravity' - to make it closed or open? (I presume you mean the Universe to be closed or open?).

No. I dont see the correlation. Read about neutrinos and gravity.
