DELVE DEEPER

[davidtimmerman]

the big bang's problem is that it didn't happen

[nobigbang]

The big bang's biggest problem that it has never happened.

[swavekbu]

200 years from now, "Remember when we used to believe in the Big Bang?"

[Quantumfluxfield]

0:40 Sean Carroll would not have allowed Edwin Hubble on his stage because in his last paper Hubble expressed skepticism of the 'Big Bang' theory and in the interpretation of the red shift as a doppler effect..

"That's the Big Bang model - it is true. There is no point in doubting..." - I would say no point in listening after this statement :) Not doubting is characteristic of religions, not science.

[p_sg]

Big Bangs, Dark Matter, Dark Energy. When are these hypotheses likely to be proved to be fact? I think never. The old adage " the more we think we know the less we realise we know"

[boy]

Humans thinks they know everything but we actually don't know shi*** about outside earth

[savedfaves]

“We don’t let people in stage if they doubt the Big Bang model”. That my friends is what’s wrong with science, the human ego.

[ericlind]

It’s not a foregone conclusion that the universe is expanding. Hubble explanation of redshifting due to Doppler effect is just an assumption.

[infinitecosmos]

Science then: Sean Carroll: We don't even let people who doubt the Big Bang on stage!
Science today: *Eric Lerner has entered the stage*

[projectprofit]

“It when from being very smooth to being very lumpy, ” as if the theory presumes this was some gradual process. No Sean. The theory the purport behind the theory is that the universe went from “nothing” to the entire lumpy universe in less than a fraction of a second, not from smooth. Because of the constant gloss over of the flaws, I’m starting to believe that this theory and many others are part of a cult. Why is there such fear of being forward about the validity of the problems with this theory?

[felixvandiggelen]

Hahaha, you should have given us Roger Penrose explaining Big Bang problems.

[brantgentry]

Well where is the antimatter from the energy that was the original singularity that formed matter? Where are the magnetic monopoles? Why isn't the conservation of angular momentum consistent? Just three questions avoided by big bang believers.

[robertsmith]

What I can’t wrap my head around is how the hell can nothing explode

[peterwilliamson]

His cred fell away when he said non BB believers were not allowed on the stage! Should have put the other side on the table.

[sinisamilisavljevic]

If there was nothing a moment before the Universe "banged", then there was not only no time, but was no space either. Knowing that, it means that the space is also expanding together with the Universe.
One of the biggest problems that I see is the question: Is matter (including light) expanding WITH the space, or WITHIN the space? This also implies questions about Gravitational Redshift.
BTW, how much of the Background Radiation can be assigned to mechanism similar to the Olbers Paradox?

[mightymips]

They claim to be able to imagine things that arent imaginable for any human being. It feels like cosmology is today more a belief (clothed by sophisticated scientific research) than a science. How can they say that they know this theory is 100% true and then keep on adding unproofable components (dark matter or energy) to their equations. How can they claim to know how the properties of light may change or not change after traveling for billions of years ....if one of their multiple guesses is wrong then everything is wrong.

[ssvvgghammer]

big bang isnt real.... honestly the truth is we dont know what happened 14 billion years ago....bruh that was along time

[christophiluslovingchristb]

How did all the matter & energy we presently see in the Universe get so very compressed?

[therealist]

Infinite energy bound into a single point in space doesn't make sense, let's just be honest here people. The running the clock backwards thing makes sense but that's the only thing that makes sense about the theory.
