No one knows whether dark matter exists or not, and very few even know what it is. The name along with its natural connotation, however, only add to the mystery enshrouding dark matter.

Dark matter was discovered in 1933 by Fritz Zwicky, a Swiss scientist. It was originally called "Missing Mass." Theoretically, dark matter makes up about 27% of all mass in the universe.

Dark matter was named as such because no light can be seen from inside the mass, making it essentially...invisible. This is due to the fact that dark matter does not emit or absorb light or any other kind of electromagnetic energy. Because of this, we know far less than we would hope to know. Fortunately, with the aid of modern technology, we can see dark matter through x-rays.

We are always researching and learning more about the universe. And perhaps someday, we will find other life.

I've been super busy lately with school work, studying, etc. Besides the fact that I do nothing but AP chemistry and AP economics, I constantly think of stupid questions that are almost impossible to answer. So, maybe you could answer them for me, and if not then we can both wonder what the answers to these 15 questions could be.

To My Loving Boyfriend,

  • Thank you for all that you do for me
  • Thank you for working through disagreements with me
  • Thank you for always supporting me
  • I appreciate you more than words can express
  • You have helped me grow and become a better person
  • I can't wait to see where life takes us next
  • I promise to cherish every moment with you
  • Thank you for being my best friend and confidante
  • I love you and everything you do

To start off, here's something I don't say nearly enough: thank you. Thank you, thank you, thank you from the bottom of my heart. You do so much for me that I can't even put into words how much I appreciate everything you do - and have done - for me over the course of our relationship so far. While every couple has their fair share of tiffs and disagreements, thank you for getting through all of them with me and making us a better couple at the other end. With any argument, we don't just throw in the towel and say we're done, but we work towards a solution that puts us in a greater place each day. Thank you for always working with me and never giving up on us.

Hauppauge is home to people of all kinds. We always have new families joining the community but honestly, the majority of the town is filled with people who never leave (high school alumni) and elders who have raised their kids here. Around the town, there are some just some landmarks and places that only the people of Hauppauge will ever understand the importance or even the annoyance of.
