5 Cosmic Phenomena EXPLAINED

Dr. Joseph Pesce explains five cosmic phenomena to include fast radio bursts, neutron stars, black widow binaries, magnetars, and dark matter. He is an astrophysicist with the National Science Foundation and has been studying space for over 30 years.

Dr. Pesce is a Program Director at the NSF, Directorate for Mathematical & Physical Sciences, Division of Astronomical Sciences. An Astrophysicist with 30 years of experience, his primary areas of interest is in the external environments of galaxies hosting super massive black holes (Active Galactic Nuclei – AGN – in particular blazars); formation and evolution of AGN and galaxies; intergalactic medium in clusters of galaxies; imaging and spectroscopy of AGN (optical, IR, UV, X-ray); multiwavelength (radio to gamma) monitoring studies of blazars; cool stars and stellar atmospheres (AGB stars, supernovae progenitors).

He is the Program Officer responsible for the National Radio Astronomy Observatory (NRAO), the Atacama Large Millimeter/submillimeter Array (ALMA), the Central Development Laboratory (CDL), the Very Large Array (VLA), and the Very Long Baseline Array (VLBA).

I have questions such as should the peanut gallery have extraordinarily real insight into this limiting the possibilities to 2 and an way to figure out which is which; what to do with that information in a zero trust environment?

Wasn't this video posted before? I mean the clipped one, not the livestream.

QUESTION: Do all galaxies eventually collapse in upon themselves? (Or is modern science wrong about 'gravity' being matter bending the fabric of spacetime?).

[LurkerAnonymous]

Dark matter is related to the expansion of the universe and you won't find that in the particle accelerator.

Consider the following:
a. Numbers: Modern science does not even know how numbers and certain mathematical constants exist for math to do what math does. (And nobody as of yet has been able to show me how numbers and certain mathematical constants can come from the Standard Model Of Particle Physics).

b. Space: Modern science does not even know what 'space' actually is nor how it could actually expand.

c. Time: Modern science does not even know what 'time' actually is nor how it could actually vary.

d. Gravity: Modern science does not even know what 'gravity' actually is nor how gravity actually does what it appears to do.

e. Speed of Light: 'Speed', distance divided by time, distance being two points in space with space between those two points. But yet, here again, modern science does not even know what space and time actually are that makes up 'speed' and they also claim that space can expand and time can vary, so how could they truly know even what the speed of light actually is that they utilize in many of the formulas? Speed of light should also vary depending upon what space and time it was in. And if the speed of light can vary in space and time, how then do far away astronomical observations actually work that are based upon light and the speed of light that could vary in actual reality?
