Description

Dark Energy

  • What observations led to the proposal of Dark Energy? Typically in science, you do not come up with an extension of your theory or propose a new hypothesis unless new data contradicts existing ideas. In other words, why did scientists begin proposing that there was a new thing we call Dark Energy and why is it called Dark Energy?
  • What other hypothesis exist for explain the observations you listed in part #1 if any?
  • What is currently known about Dark Energy?
  • What are some of the current unknowns of Dark Energy?
  • What future experiments are being done that can shed light on Dark Energy?
  • In light of all of this, what is your personal opinion on Dark Energy and its validity as a scientific explanation?

Dark Matter

Typically in science, you do not come up with an extension of your theory or propose a new hypothesis unless new data contradicts existing ideas. In other words, why did scientists begin proposing that there was a new thing we call Dark Energy and why is it called Dark Energy? 2) What other hypothesis exist for explain the observations you listed in part #1 if any? 3) What is currently known about Dark Energy? 4) What are some of the current unknowns of Dark Energy? 5) What future experiments are being done that can shed light on Dark Energy? 6) In light of all of this, what is your personal opinion on Dark Energy and its validity as a scientific explanation? To answer these questions you will watch two documentaries and read a few articles to perform your analysis.

I would be disappointed, but not for very long because that's the way science is. You have to accept the evidence. And if it turns out that I wasted my life working on the wrong hypothesis, so be it. What I really want to know is what is the universe made of. Let it be cold. Let it be warm. I just want to know what it is.— Professor Carlos Frenk, who’s spent his life researching Dark Matter In this lab we will examine the evidence for Dark Matter and Dark Energy and look at some recent research results. We will go through the scientific process and despite not being experts (or science majors!) you will present your findings at the end of this study. The parts to your report will not be a formal lab report but rather in the following format for both Dark Matter and Dark Energy: Dark Matter 1) What observations led to the proposal of Dark Matter?

Part 1
Dark Energy
Dark energy is defined as a form energy that is known to exert negative pressure but also its
known to be different and opposite to gravity. The energy is known to accelerate expansion in
the universe. This conclusion has been driven from the gradational observations that are from
interactions from astronomical objects. According to the recent studies the mysterious energy is
what is pulling the universe apart and it is doing so at an increasing speed. The mysterious
energy is known to have bee from the universe matter that seems to be invisible.
Other observation is that dark energy is also a property space. The explanation of the existence
of dark energy is based on quantum theory. The theory explains that the empty space is full of
temporary particles and they seem to contribute no energy to the universe. Another explanation
the energy is a new dynamic energy fluid (Perlov, et al. 2017). Dark energy is the o...
