New method 'confirms dark energy'
First results from a major astronomical survey have confirmed the existence of mysterious dark energy using a cutting-edge technique.

Dark energy makes up some 74% of the Universe and its existence explains why the Universe appears to be expanding at an accelerating rate.

The finding was based on studies of more than 200,000 galaxies.

Scientists used two separate kinds of observation to provide an independent check on previous dark energy results.

3. How so?
We would still be constrained by the speed of light, right? The nearest galaxy is, IIRC, like 25,000 light years away.

Subjective time.

6. You are mistaken. Dark Energy does not move objects. It expands the space between them.
You can't travel with Dark Energy. You can increase the distance between you and your starting point, but that doesn't mean the distance between you and your point of destination would decrease.

5. Bingo.
They are right. There is a cosmological constant.


And they are right about it having some thing to do with dark mater.

And yes. It has a lot to do with going to other galaxies.
