many thanks Chronos

I've heard that most of dark matter is located in the outer portions of galaxies. If that is so, wouldn't the gravity from the dark matter tend to pull the galaxies apart?

doesn't flat mean that the universe on average is not warped by gravity. It is warped locally by every particle of mass but on the average the warped space and the unwarped space even out. If true, that seems to me that the unwarped space is getting additional space from other dimensions.

Since it takes time for gravity to have an effect on a neutrino, wouldn't a neutrinos velocity be greater than expected when entering and passing through a gravitational field, i.e. faster than light neutrinos passing through part of the earth?

does weakly interacting also mean that they interact infrequently?

does the fact that neutrinos are only weakly interactive change that? In other words, since neutrinos are weakly interactive they didn't know to slow down in the presence of relatively high gravity.

Those faster than light neutrinos were moving through a location of high gravity (inside the earth). In such locations space is contracted more than in empty space. Therefore getting from A to Z is a contracted distance. Question: could neutrinos move through contracted space at a greater...

Why do we need helium for star formation?

thanks.

at the end of these 100,000 year cycles of temperature, what causes the peak temperature to fall?

thanks.

I understand how increased CO2 increases the temperature but how does an increase in temperature increase the CO2 level?

is it practical to plant large amounts of these types of vegetation to make up for increased CO2 production?

what type of vegetation uses the most co2?
