    If we can move at the speed of light, can we pass a small hole?

    If… If you assume something that's impossible, you can conclude anything. So yes, if massive objects can move the speed of light, they can also pass through small holes.

    Why do people think the universe is finite?

    What a lot of questions! As a starter to a starter, I would like to comment. Why do people think the universe is finite? - It depends, whether you mean *some* people or people in general. Some people think the universe must be finite because they consider infinity as a construct of the human...

    Question about dark matter gravity and the expanding universe.

    Thanks for clarifying this. I knew the cosmological constant had something to do with it, but had no idea the formula was as simpe as that. I guess those papers are so full of formulas that I couldn't grasp the essence. However, two questions remain unsolved for me. 1. Why do we regard the...

    Question about dark matter gravity and the expanding universe.

    I would like to reply to the original question. It has already correctly remarked that dark matter still has normal positive mass, and can therefore not be a source of "anti-gravity". However, dark energy might have that property. Although the formulas for electromagnetism and gravity are...

    Sum of squares of prime factors

    Yes, it's obvious, because in series A166319 it is allowed to incude 1's in the factorization. That means that you can make any sum of squares that is deficient (d_n<0) equal to the required number by adding an arbitrary number of 1's. A166319 also allows non-prime factors, but this is just a...
