    Undergrad Could a planet get heavier without needing to grow in size?

    Hi! Could we (at least) in theory change a planet's weight with denser core material so that it could be as large as it is, but have increased the gravity to the level like earth?

    Undergrad Why do sources give different ages for the first radiation in the universe?

    Sorry, have been off for some days.. ..Thanks, the acoustic peak was something new. I will absolutely report back if I find any more of information from the web.

    Undergrad Why do sources give different ages for the first radiation in the universe?

    Because I am new I cannot really discuss more in detail about complicated things yet.. But I can try to.. :) If there was gravitational waves, wouldn't they leak out from any fog whatsoever? Also, would the waves even survive 13.7 b-years if we could detect them?

    Undergrad Why do sources give different ages for the first radiation in the universe?

    Ok thank you, so there was radiation and later even optic light maybe before 3 min but everything was blocked by gasses until 380 000?

    Undergrad Why do sources give different ages for the first radiation in the universe?

    Hello, When did the really first radiation occur in the universe? I'm very confused from different sources: 1." The oldest radiation in space comes from 380 000 years after the big bang. 2. In the photon epoch three minutes after the bigbang was almost only gamma radiation. 3...

    How is Deuterium formed from Hydrogen in the universe?

    Thanks for your help , If I also might ask: Did the decay have anything to do with the process of creating the first atoms, or, did it happen after? And, which came first, Alfa-decay or Beta-decay? Alfa decay is from what I've understand only for helium-nucleus.

    How is Deuterium formed from Hydrogen in the universe?

    Hi, quite new in chemistry.. I would like to know the beginning of the atoms in the universe. Therefore I must understand the process from Hydrogen to Helium. But to create Helium you need the isotope(#2) "Deuterium" from Hydrogen. But how did the Deuterium form? From two Protons...
