1. Yes, the consensus is that the big bang started as a singularity, but you must have misread. Though it was the source of protons, neutrons, and electrons, those things could not exist in a singularity, not in the way we know it to exist anyway. And though there are alternative theories, none come close to the amount of supporting and compelling evidence that the big bang has. Whether the Big Bang happened or not isn’t the big question anymore. The real question is what came before the Big Bang.

2. Anyways, thanks for discussing this with me. I have leamed a lot.

3. I’ve read up on some proposed theories that the big bang arose from a singularity which contained everything (protons, nuetrons, electrons, electromagnetic radiation, exe…). That makes some since to me, but like you said, no one really knows. Something gave rise to something else, hense an infinitive process. Maybe the big bang didn’t happen. There are alternative theories. Whatever the case may be, I think one must look outside of time, matter, and space to find the answer.

4. And where did it come from? Like I said before that’s outside the realm of science.

5. Though matter absorbs and re-emits electromagnetic waves, that doesn’t mean matter is the original source of electromagnetic waves. Especially because you would still have to ask where said matter received that energy in the first place. Energy existed first and then later converted into the fundamental particles (which are ironically, ridiculously complex) not the other way around. Complex things don’t simply appear. Practically speaking, raw electromagnetic energy is as simple as you can get.

6. From what I can gather, as atoms have energy put into them, such as heating an element, they also lose evergy which is released as electromagnetic waves of radiation. So I guess I’m wondering how electromagnetic radiation could have been given off if matter was not previously present. If not given off, then where did it come from? Are there other sources that could have emitted this radiation?

7. There was no initial fusion or fission that produced the big bang. In science, the big bang is the beginning. What caused the big bang is outside the realm of science, because it is outside of the knowable/observable universe.

8. I’m sorry I should have been more specific. I meant electromagnetic radiation, which is light, not matter. So there was definitely no alpha radiation which is matter (it’s actually helium nuclei). There was gamma radiation which is already in the form of light. And then beta radiation, which are just electrons, were later formed from that energy (E=mc^2). The processes you’re referring to that produces alpha, beta, and gamma radiation from matter are fusion and fission.

9. You’re right, energy is not composed of anything. I stand corrected. From what little I understand of radiation, there are three types being alpha, beta, and gamma radiation, all of which are produced from matter. So it’s my naive understanding that some form of matter was present giving off radiation which somehow caused the big bang. Following that were fission and fussion processes which converted lighter elements into heavier elements, hense chemical evolution.

10. Energy isn’t “composed” of anything but it takes different forms. What energy is CAN be difficult to explain or wrap your head around. The energy of the big bang wasn’t any kind of “special” energy that is different from the kind of energy we have today. It was basically in the form of radiation which was then converted into matter and kinetic energy. Matter itself is not energy, but matter and energy have a conversion factor given by: E = mc^2.

11. What was that raw energy composed of if you don’t mind me asking? I mean we have nuclear power plants that are powered by the process of fission. Some time in the near future, they will be replaced by nuclear fussion power plants. Has this explosive release of raw energy that you speak of ever been artifically simulated?

12. No, fusion came much later. The Big Bang was, to put very simply, an explosion/expansion of raw energy. That raw energy quickly converted into “matter” in the form of simple particles like protons. Later on those protons would fuse together to form heavier elements. Later, some of those heavier elements decayed back to lighter elements by Fission.

13. Thankyou for your answer. Do you mean to say that fussion was the process that caused the big bang? I’ve just begun to take a greater interest in science, and so I have a lot of questions.

14. Actually, matter came about through the big bang in a very different way. And, the vast majority of what was formed early on was mostly protons (hydrogen nuclei). The much larger/heavier elements such as uranium were created much later through FUSION reactions as opposed to the FISSION reactions like the one seen in this video.

15. Great illustration! Could this in any way explain the big bang theory? Just curious.

16. Nice Teaching Method! I like all of your videos! I Love Science! Keep it up! I love to learn! 5/5!

17. good job

18. Right on!!! Keep ’em coming!
