Life is only given motion through various particles of matter in many forms.

Currently, however, these observations do not provide a clear picture of what a dark matter particle looks like.

In and of itself, it's obviously not a demonstration that we've detected dark matter particles.

In theory, absolute zero is the temperature where the particles of matter stop moving.

They became curious about the bonds that held the smallest particles of matter together.

Secondly, because one particle alone of matter cannot be cogitative.

This collision changes the velocity of the second particle, just as if there had been a force between the two matter particles.

It is based on the theory that in the early universe, cold and slow moving dark matter particles clumped together.

Atoms, which are particles of matter, couldn't pass through.

There is not probably, at present, in the whole universe, one particle of matter at absolute rest.
