space questions

[TCIB]

Your most welcome mate.

I missed the bit about deflation.
This is where our understanding of physics breaks down tbh mate.
Like are we in a black hole now, inside another, inside another.
These are theoretical possibilities physics allows for but there are things we just do not know like what is beyond the event horizon of a dark star (black hole).

You add in the chance of a multiverse a concept i personally feel is perfectly feasible.
Like bubbles in a glass, each a universe. Well we do not know if this is the reality of this universe right now.
These ideas and theories are possible but we simply do not know how the universe came to be as it stands or how it works on the grandest of scales.

How hot can something get? Is there a limit or does it just keep going on and on... And what's the hottest thing in the universe.

Same for cold.

1.416833(85) x 10^32 Kelvin is the theoretical maximum temperature in this universe.

Sorry its late. :-)

If you could somehow travel 100 million light years from earth in an instance and you had an extremely powerful telescope pointed at earth, that could see everything. Would you see dinosaurs?

even I could work this one out and the answer is no

when we see light from very distant or even long dead stars it is because it has been travelling for so long to reach us and nothing to do with actual time travel

The answer is yes by travelling 100 million light years instantly you have travelled faster than the speed of light so the light you would see from the earth would indeed be from 100 million light years ago, much the same as we see stars now, which may have died out a million years ago.

This the simplest answer that doesn't factor in the theory of relativity that states the faster you approach the speed of light the slow time goes relative to someone else observing it, the clock on the international space station will tick over slower than a clock on earth so astronauts that live on there come back to earth ever so slightly younger than if they'd stayed on earth, but that's another story

if you could travel faster than the speed of radio waves you would eventually catch up with the Aguerooooooo moment which would be live, it takes 30 minutes to receive a radio signal from mars 'that should give you some idea of how far you would have to travel', the Aguero goal would be near to Alpha Centauri around now which can be seen in the night sky and is just over two light years away, Hitlers speech declaring war would now be at planet called HD217107 which is 65 million light years away again that can be seen with the naked eye

Talking with my dad the other day after watching a programme on black holes and the scientists working on that sort of thing and we both thought the same thing what do we gain from this knowledge of all this stuff. I can understand going to the moon and Mars as our next step in the universe but why do we need to know about stuff billions of light years away what good does it do surely that money could be used for better things.

black holes or inventing the wheel, both the same things in terms of scientific research, its human nature to progress and better what you have, if we want to progress and travel in space we need to know how black holes are born, work and then die

So all the rags on Alpha Centauri will have seen it then? Just imagine their little green faces....

I thought about this the other day, just the moral side to it really, the money spent on finding all this stuff out. I wonder who decides how much money or time we are to spend actively researching this stuff. If the answer is "we do" as in mankind in general, then I reckon in a few hundred years, this kind of question won't even be asked.
What else is there to do? I've found myself asking. We can only keep going as long as there are new things to understand can't we? Do you ever think we'll get the answer to everything? We can't predict the weather can we because of the chaos, but maybe one day we will be able to.
I don't know. How important should discovery be? Is there even an answer to that.
