I think we are collectively getting a good overall look at this. After thinking about it overnight, I can see that the hot air is being forced along...

There is a party trick. You hold a tube over a candle. The real “chimney” accelerates the flow even more than the natural effect. It’s also the cross...

Is there a way to age stars, within a galaxy 8 billion, years away. Can we look at one star in the galaxy and say it looks 4 billion year old at the...

Midway in the Mk1-2 builds, which made rings using steel plates, SpaceX iterated the design to use monolithic (one piece, single weld) rings...

Thanks Is Reverse Time Dilation better?

Turbulence with that greater distance might help get the wheel turning, overcoming the static coefficient of friction. I still think the increase in...

You are right - in the convention you are using I left out the minus sign. My bad. So if you are happy with this statement then there is no...

Thx.

'Expert judgement', eh?

The verb to age meaning "determine the age of" rather than "allow to mature by the passage of time", I think. Grant Hutchison

You misunderstood me, I never claimed that this is one event, Shaula, I defined 2 events as the limits of the spacetime interval. What I mean, is...

It may be a more minor point, but I'm not so sure 'we are probably not ready' for replacing the naivety of MIR thinking with the responsibility that...

Unless you are talking about creating whiskey at high redshifts, your question doesn't make much sense. Could you ask it again, perhaps with more...

Location of a fan/heater off frame perhaps. A lot of things have to come together

In regions near hot stars, some hydrogen atoms will be excited to energy states of N=3 or higher (where N=1 is the state with lowest energy, also...

Just his grousing I suppose. So, how would the SLS and Starship tank failures compare, psi wise. I've heard it said that SLS did well after exposure...

You can add text to the box in your original graphic simply by opening it in a text editor and replacing some of the spaces with characters to spell...

Where R-7 was strong enough to walk on, so the saying goes. The West thought to shave weight off every little thing. The Russian answer? Make...

Where's the angular momentum coming from?

You defined two points in space. Your example treated them as one event. What you actually have is "The observer makes a measurement of the...

I wonder if an invisible vortex might be at work, hairy ball and all that. Spacing the candles just so may be an influence?...

I wonder how that compares to Starship's tank test.

Sad all the same.

Now for some model spacecraft from him---I hope.

I like this thread https://www.trekbbs.com/threads/feline-follies.162271/page-192#post-13153955

Once this ability exists for humans to have an impact on their evolution, either intentionally or unintentionally, would evolution have the same...

A bad few days...
