CRCT QUESTIONAccording to the big bang theory, the universe is about
A. 470 billion years old.B. 500 billion years old.C. 4.7 billion years old.D. 13.7 billion years old.
Prove that the following wff is valid by means of resolution:
xp(x)v xq(x)xp(x)vq(x)Why can’t you do this problem?
You cannot do these problems because you do not know the math between what you now know and what you would need to know to do the problem!
You will have the same problem with understanding the process that scientists call the big bang.
Just because you cannot understand some of what scientists say about the big bang does not mean that scientists do not understand it clearly!They know the science between what you know and what is needed to be known to understand the big bang!
e. Instead, it was theexpansion of space and time itself, and thereforeoccurred everywhereat the same time.
f. Any galaxies fartherthan ~ 13.7 billion ly away we cannot see!
Why: because the light hasn’t had time to get here!!!
Are there galaxies beyond what we can
see?
Astronomers think that answer is
yes. We just can’t see them.
RED SHIFT
What you just heard was the Doppler effect with sound. Red shift is the Doppler effect with light.
3. From our position in the universe, it looks like we are the center because everything appears to be moving away from us.
Ex: If your galaxy was a raisin, notice that every raisin is moving away from every other raisin. In fact, a raisin far away from you is moving away faster than those that are closer. Our expanding universe acts the same way.
Ex. This is like an oven that was used to make cookies. The cookies are not visible but the smell is there (evidence) and when you open the oven door there is just a little bit of heat still there (another piece of evidence).
What are the two pieces of evidence that
support the Big Bang Theory that we
discussed?
