Hallo, I have a new theory:

- We all know that matter and energy can change to eachother. (e=mc2)

- If matter has a weak attraction effect (known as gravity), maybe energy has a weak repel effect (dark energy?).

There is some experiments that we can do to test this theory. We can weigh a block two times. At the first time we weigh it hot, and at the second time we weigh it cold. The hot block must be lighter than the cold one (becouse the hot energy repels with the gravity of Earth). We need to have a very precisely weighing-machine to do that.

Another experiment is to look at the moon when it is half lighted. My picture shows my idea. The illuminated side has more energy (is hot) as the dark side (is cold). The light of a star saw near the hot side must be less bended than another one near the dark side.



If that is correct, the expansion effect in the universe can be results of repel effect of the energy of the cosmic microwave background radiation.

What you think?

You seem to be saying that because energy and mass are the same, they should behave oppositely, which just seems illogical to me.

I will make a prediction on the outcome of your experiment. You will find that the hot block weighs more.

I think its a great creative idea!  Now you just have to test and try to prove it!

You will first have to find a way to make the block heat up from itself, because if you heat it with another device, there's transfer of energy from the heater to the block, which would make the comparison to weighing the cold block rather senseless

The link indicates that a chunk of metal heated in a certain way loses mass because of out-gassing. If matter is allowed to leave the scene, measurements won't mean much, unless you are interested in the out-gassed product.
