Finally, there is Red Supergiant planet that is hugely bigger than other planets.

What is the Universe Expanding Into?

I think that if America gives up all of its nuclear weapons, America won’t be safe. And I think other countries that have nuclear weapons such as China, Russia, the UK, Israel, Pakistan, France, and India will not give up their nuclear weapons. Also, since North Korea is developing their nuclear weapon, they will not give it up. My opinion is that such countries would not give up nuclear weapons and terrorists also would keep strict watch against these countries.
