I like the part where he describes the Higgs Particle in empty vacuum as being present. Have you heard Kim Giest's explanation that each CM3 of empty space weighs 1 trillion tons & do you agree with this?

[stevebd1]

I think what you're referring to there is the cosmological constant problem. Using cosmology, the 'density' of the vacuum is calculated as being about 0.67x10^-26 kg/m^3 but using quantum mechanics, the figure works out at 2.08x10^94 kg/m^3(!) which is a staggering difference in the order of 10^120.

[stevebd1]

To account for this large difference, it's thought that there's some process in place where virtually all of this mass/energy is cancelled out at quantum level, leaving the small amount we observe in cosmology. One analogy would be when using long division to divide a large number; we generate a lot of intermediate numbers which we then discard once we have the answer. This is one of the major problems facing physicits in unifying GR and QFT.

this kook doesnt know what he is doing he talks of science that is untested and he is creating theories out of calculations by Hawkins theory black holes in any shape or form should never be created no matter how safe they say they r

@dem0nthesis Richard Feynman is one of the most famous theoretical physicists and he didn't smoke weed that often. Being a theoretical physicist is a hard and long path that takes a lot more than pot-smoking

[frisc45]

how exactly do you get vibrations in a vacuum when there is no medium to cause vibration?

@dem0nthesis

before i became a theoretical physicist i was a pot head.

ironic

[musicalgenius1234]

@dem0nthesis What the fuck are you on about. Im doing a phD in theoretical physics and Iv never encountered any evidence of an elevated substance abuse amoung theoretical physicists. Lol what a bizarre comment!

[dem0nthesis]

SCREW THEORETICAL PHYSICIST, Seriously every pot head in my school claims to want to be one, no offense to this guy he knows his stuff, but most of the theoretical physicist majors i know are pot heads pretending that lighting up and bouncing ideas off one another will help them discover something that people care about. Why is theoretical physics such a pothead magnet?

To bad we're all going to die when the thermohaline circulation shuts down. Wont it suck...?

Science is mankinds pursuit of knowledge and truth. Because what we are finding over and over and over again discredits faith based ideologies, we see people all over the internet attacking science with outlandish claims and ignorant and/or manipulative statements. Grow up people. We only have one Earth, one life, and one chance. Its time we stop depending on a supernatural ideology and start working together for the betterment of mankind.

@Midnightrider1126 I love that you use a FICTIONAL movie to try and confirm your point. Based on this short paragraph, your way of understanding astounds me. Science is about UNDERSTANDING. no more no less.

You ever seen the movie Hell Boy.Watch the first one,pay attention to the beginning on where the so called Hell Boy came from.Read Genesis chapter 6 verse 4 -7.Studying the world is not the intent at all.Trying to disprove creation is, bringing back the fallen angels is.Look up the Nephilim giants on you tube.The gov has put a lid on this,because this gives credit to the Old Testament.Look it up for yourself.You really have to start in Genesis and continue to read,it all falls into place.
