Time Machine.

First, we wont get broken down to pieces in a wormhole. Whole idea of it is to create a shortcut in space fabric - like a tunnel through mountain.

 

Hypothetically you need a white hole and a lack hole to create a tunnel. If u get broken down in wormhole, ur doomed

 

And about Timetravel... you can travel into future for sure, but past... i doubt... you can only see past.

And once you travel to the future, you cant get back (unless someone invents timetravel to past- but then again perhaps he changed something in past and timetravel will never be invented Oo).

 

Well then, you know more than anyone else on this planet , young sir.

max.. No.. I do not see why thermodynamics would be affected by the speed of the traveller?

 

If in my rocket I have an oscillating atom radially to the travelling direction (and let's say it is 'fuelled' by temperature, or rather is a function of temperature), then why as the speed would increase, would the system lose thermodynamic energy?

Actually, that makes sense. If someone is looking from outside the ship, they would see that all the people are approaching stillness and not moving. So, the particles also get slown down. The definition of temperature? The average thermal collisions by the movement of the particles. At absolute zero, the movement of the particles is zero. The electrons even stop spinning.

 

Of course only somebody on the outside of the ship would see the temperature at 0° Kelvin, inside the ship it seems normal.

No object ever reaches absolute zero. They only approach it. It is an unattainable idealization, and, additionally, the temperature "outside the ship" is above it. Not trying to take the wind out of your sails, but perhaps help you to keep your feet on the ground.

Okay, here's a better analogy to help you with this, I think -

 

We, at the Earth, treat our OWN *moving* reference as the "still" reference. We are moving - around our own planet, around the sun, around the galaxy, etc etc.

We are not, however, the absolute reference frame, because such a think does not exist.

 

For that matter, an entity living in a "slower moving" reference frame than us would consider us the faster moving reference, and would philosophize on what we feel when time slows us for us.

 

The fact is that we *don't* feel it. For us, this is the "correct" time frame and anything slower or faster is the different reference.

 

There are no absolutes. Everything is relative. That's the point. Conceptually, there's no difference between the relationship of our reference to your moving reference and between an entity moving slower than us to us.

 

There is no absolute reference.
