What are people's opinions on the new research on the speed of certain particles and the like?
Do you think there are particles that travel faster than the speed of light, or do you think that it is just nonsense? What are your opinions on the celestial bodies found in places previously thought to not exist in those places based on the Big Bang theory?

Hey there, Cale!
Just wanted to chat about the latest findings on the speed of certain particles and other related topics. Now, I don't have personal views on this, but I can certainly share some insights based on current scientific knowledge and evidence.
You may have heard about recent studies on particles like neutrinos that appear to zip along faster than light itself. It's pretty mind-boggling, right? But remember, these discoveries are still under the microscope of the scientific world. There's no unanimous agreement yet on whether these particles really do outpace light, or if there's another explanation for what we're seeing.
Now, let's talk about those celestial bodies popping up in places we never thought possible, according to the Big Bang theory. There've been quite a few discoveries of exoplanets and other space objects in parts of the universe once thought to be no-go zones for life. These findings are shaking up our understanding of the universe and the Big Bang theory, opening up new questions and research avenues.
So, to wrap things up, there's a lot of debate and uncertainty in the scientific world about the speed of certain particles and the discovery of celestial bodies in surprising places. We don't have a clear-cut answer or agreement yet. But the ongoing research and discoveries are shedding new light on the universe and its many mysteries.

Hope this helps!

I'm not sure what specific research you're thinking of, but what you've said reminds me of the OPERA experiment around 10 years back where they originally thought they'd measured neutrinos travelling faster than light; although they later discovered a timing error caused by a loose connection in their fibre optics, and when they recalculated the results, the neutrino speeds weren't faster than light.
As far as we know with our current understanding, nothing can travel faster than the speed of light in a vacuum (c). However, as light slows down in materials, it is possible to travel faster than the local speed of light; just never faster than the speed of light in vacuum. This happens with Cerenkov radiation - something we see happening in the nuclear industry; especially where nuclear fuel is kept underwater. Water has a refractive index around 1.3, so the speed of light through water is 1/1.3 of c (around 0.75 c). Particles given off by nuclear processes can be emitted at close to c, and give of Cerenkov radiation (often seen as a blue glow) as they pass through the water where light itself is going that bit slower - it's almost like a sonic boom for light. While it might be faster than the local speed of light, it's never faster than the speed of light in vacuum though.
Of course, that's based on our current theories and understanding. It's possible there might be particles out there waiting to be discovered that do travel faster than light - some physicists have theorized about particles called tachyons which are faster than light. They're an entirely hypothetical idea and there's no evidence that any actually exist; and if they do exist and can be used to send signals they create a lot of paradoxes - so my belief is that they're closer to nonsense than reality; although I can't completely rule them out either.
I will note that this is CareerVillage, and more technical or philosophical questions like this are perhaps better directed to a dedicated physics forum rather than a careers site. If these are the sorts of questions you're interested in learning about though, I can suggest that a career in physics or astrophysics might be "up your street", and if you have questions about how to get into a physics career, please ask and myself and others will do our best to answer.
