Some academics at the annual Indian Science Congress dismissed the findings of Isaac Newton and Albert Einstein.
Hindu mythology and religion-based theories have increasingly become part of the Indian Science Congress agenda.
But experts said remarks at this year's summit were especially ludicrous.
[...] The head of a southern Indian university cited an old Hindu text as proof that stem cell research was discovered in India thousands of years ago.
G Nageshwar Rao, vice chancellor of Andhra University, also said a demon king from the Hindu religious epic, Ramayana, had 24 types of aircraft and a network of landing strips in modern day Sri Lanka.
Another scientist from a university in the southern state of Tamil Nadu told conference attendees that Isaac Newton and Albert Einstein were both wrong and that gravitational waves should be renamed "Narendra Modi Waves" [Narendra Modi is the current Prime Minister of India].

Heating the water increases the volume the water takes up where the photon hits, this is the opposite of what would happen if you hit it with matter (the water would move away from that spot).
Im just saying photons arent matter and have no volume, not arguing about the mass. Its in the intro to that wikipedia matter page.

You are inaccurate. The water does indeed move away from the spot as energy is imparted to it from the photon. What is different is that water can fully absorb the energy of the photon.
Wave/particle duality is as much a thing for photons too. The whole issue is a red herring. Dark matter is just a label like dark energy. What generates the observed effect described by the label need not be matter any more than the latter need be energy.

No, in the usual context dark matter means some sort of exotic matter at this point: https://en.wikipedia.org/wiki/Lambda-CDM_model [wikipedia.org]
And you have chosen to have your own definition of "matter" different from everyone else, whatever, but stop pushing it like it is standard

khallow is using 'matter' where he should be using 'mass', but other than that minor difference in terminology, he is pretty much entirely correct.

Yes, I know. That is the topic of discussion. Here is what I said above:
Khallow dont agree.

That amounts to less than nothing, since khallow is not a scientist, or astrophysicist, or meretrician or opthamologist. Khallow is just, khallow, a teenager who has read Ayn Rand, and can't get her out of his pants. So sad, too bad. Poor khallow. Sometimes, suicide is the only honorable way out. That, or accepting that as an non-communalist, you still have to accept Medicare and Social Security, because the Commies prevented you from having a pony at your twelve birthday, so something like that.

And I don't agree because the distinction is meaningless. Everything with mass has volume (and hence, checks off all the boxes for "matter")? Nor when we actually look at cosmological scales does the actual volume of would-be matter become relevant. For example, global clusters, large clumps of stars, which sometimes have billions of stars in them, can orbit for long periods of time without a collision occurring (for example, we have yet to observe such a collision in the globular clusters that we can see with the human eye, which is several centuries worth of observation over several dozen huge clusters). The volume of the matter in the global clusters from the stars is a minuscule portion of the volume of the globular cluster.
I don't believe in paying lip service to pedantic semantics when it's irrelevant to the topic.

Everything with mass has volume. Photons have volume. Therefore, photons have mass.
Corollary: interstellar space has volume. Therefore, interstellar space has mass. No need for dark matter.
