Effectively if we look at the orbit velocities of galaxies as a function of the radius, further out stars orbit faster than they should if we consider only luminous material in a galaxy as mass. On a larger scale this happens with galaxy clusters. We therefore posit the existence of a new form of non luminous "dark" matter to explain it. The matter discrepancy also popps up elsewhere giving the same expected mass ratio of 10 parts dark matter to every one part of luminous matter.
Dark energy drives the expansion of the universe. It is the non-zero vacuum energy of spacetime (and the reason gravitation dosesnt play nicely with field theory). As the universe expands this dark energy, which is effectively a non zero energy density at every point, increases as there is more space in the universe so acceleratingly drives expansion.

alright
what do ur job propsects look like?

No, not near death stuff.
Its been studied for decades so its most definitely reproducible. Some of the examples are so far beyond chance that there has to be something to it.
For example, someone gets told to remote view jupiter. Noone believes what he reports, then 5 years later its discovered he was right.

Hey OP. What's your opinion on worm holes? I've read about them being created in a lab environment eventually. And what about super massive black holes? Do you think that telescope cluster is going to find something significant about the milky ways black hole?

Physics major heading in to second year… I feel the same. I really have no idea where I am going with it but I figure I can't end up a total failure if I complete the degree, and I feel it is a pretty noble pursuit. Like you I am racist and cynical but my inner-aristocrat tells me to take the path that will lead to higher knowledge rather than the one that will lead to monetary reward.
Did you finish your degree? Am I a retard and should I look in to engineering as soon as possible? pls respond
Nathaniel Moore
Some of the smartest physicists to ever live would disagree with you.
Hey OP, how would you have responded to pic related? Showed up in a completely unrelated thread a few days back.

So we know that God created the universe and gave his only son so that we may all be saved but is there a way physics can prove God's moving hand in the universe?

I think we need to wait for gravitational wave astronomy to get big. This will take about 10 years. Then we will see some really cool shit.
If you are feeling meh about physics and don't enjoy it, don't go into it. The good news is that it is easy to jump into engineering and u will make big bucks. Your call man. I just finished my degree.
What people don't understand about general relativity is that it is the theory where truths are the same in all frames related by a lorentz boost or translation. That is how it is built up. "relativity" is a bad name because the whole point is that truth is the same in all these frames. Nothing relative about it.
We have just confirmed gravity waves directly and every binary system decays according to GR. It is our second best tested theory after quantum field theories.
The main point with the eclipse test is that the sun acts as a lens. The EM field of the sun is not constant around its circumference thus even if the EM field could bend light it wouldn't act as a lens.

you must be confused sir the universe was made from akashaand jesus was a hermetic wizard
