They are guessing, using known facts but those particular facts in no way support or show that theory. They’re snake oil salesman or you are. Haven’t seen scientist doing the actual research as dogmatic as you all on here.

The Big Bang Theory is our best guess about how the universe began.
Thank you for demonstrating to me that you didn't read beyond the headline, thus confirming what I said in the last post.
No wonder you think scientists are just guessing. You can't even be bothered to read the science behind it.
You're not going to learn anything that way.
Snake oil salesmen don't tend to have evidence that their snake oil does anything they claim it does.
Scientists have a lot more than that, thankfully. If you'd just read the article you linked beyond the headline, you'd know that too. There's a reason I keep referring to cosmic microwave background radiation and Doppler red shifts, which of course, are discussed in that article.
Read it through to the end, I dare you.
