It is a legitimate area of research. But its is very much not accepted science. That is to say its ok to dive deep into the maths of how the Big Bang got going (inflation) and work with things like the Inflaton Field and perhaps there might be parts of String Theory where this stuff is part of the research. But its not like the Big Bang as in something that is widely accepted.

No there’s many research papers on those topics you can read yourself! Here’s one about the multiverse: https://space.mit.edu/home/tegmark/multiverse.pdf

There are people who make pseudoscientific theories/claims and even papers but most of them barely make it past peer review.

I’m sure with a massive amount of energy and effort we could manage it. Say we figure out wormholes maybe.

For all we know the other universes could have completely different sets of laws of physics. Or maybe the other universes are just copies of our own from every single possibility or maybe ours is a copy of another.

I’m sorry to say that the answer to your question is only hypothetical but it’s impossible to really know with the information we know now.

The multiverse idea is highly speculative. And we still do not understand whether the laws of physics as we observe them are the only way a Universe can be organised. So there is no scientific answer to your question but the multiverse theories such as the Inflaton Field would not likely end up with our laws of physics. The concept of space and time is rooted in our Universe, the Universe as far as we know. So there would not be 4 dimensions for us in other "multiverses"

My family lives in northern france and my dad enjoys space stuff. What must they expect to see ? Is it gonna be like a shooting star or bigger ? How long does it take to burn ? And does anyone knows where to look at in the sky ? (Like around which constellation)

Edit: Aaaaah I'm too late, I just realized

Not unusual at all, sadly, and many people don't even know they're missing it. I'm glad you have the experience now.

Take this as a call to action. Maintaining and even expanding dark skies is a choice. One that only gets made with the support of people like you who can share things like this.

I've seen the Milky Way. First saw it when I went to Clearlake camping with my family and our family friends. I looked up and said "what's that glittery stuff in the sky." My cousin replied it was the milky way. I stared at it in awe for a good 10 minutes before a friend snapped me out of it to grab dinner. "Your alien family will be here soon they said." He told me

It's exactly zero threat. The headline is a clickbait.

About 25 million meteorites enter Earth's atmosphere daily. Most of these are tiny, but there's larger chunk of rock here and there among them. Almost all burn up in the atmosphere, depositing some 1000 tons of dust. Every single day.

For something to survive trip through the atmosphere all the way down to the surface, it'd need to be at least 5 meters in diameter. About 5 times wider than this thing. Give or take, about 2 make it to the surface every single day.

If somebody lives in northern France, they should enjoy the show. Not panic. This thing is way too small. It's likely not even the largest one to hit the Earth today.
